The accessory device matches the target device number with the first device number, and determines the electronic device corresponding to the first device number that is consistent with the target device number as the target device, and the first device number is the same as the target device number. The device number of the electronic device to which the accessory device has established a wireless connection;

The accessory device is paired with the target device.

It should be noted that when the accessory device is in contact with an electronic device, a first communication connection can be established between the accessory device and the electronic device.

The above electronic device may transmit the first signal to the accessory device through the first communication connection. The first signal includes a target device number, and the target device number is the device number of the electronic device.

The specific type of the first communication connection can be set according to the actual situation. In some embodiments, the first communication connection may be an electrode channel formed by the electrode of the electronic device and the electrode of the accessory device.

At this time, the electrodes of the electronic equipment, the electrodes of the accessory equipment, and the insulating medium between them form a capacitor. The capacitor has the characteristics of passing AC and blocking DC, so the above-mentioned electronic device can transmit the first signal to the accessory device through the above-mentioned first communication connection.

In other embodiments, the first communication connection may be an NFC connection established between a Near Field Communication (Near Field Communication, NFC) module of the electronic device and an NFC module of an accessory device.

Because the communication distance of NFC connection is short, usually 0 to 4 cm, when an accessory device is in contact with an electronic device, the accessory device can usually only establish an NFC connection with the electronic device, but cannot establish an NFC connection with other electronic devices. , thus ensuring that accessory devices are not disturbed by non-contact electronic devices.

When the accessory device obtains the target device number through the first communication connection, the target device number can be matched with each first device number.

The first device number is the device number of the electronic device that currently establishes a wireless connection with the accessory device.

If there is a first device number consistent with the target device number, the accessory device may determine the electronic device corresponding to the first device number consistent with the target device number as the target device, and pair with the target device.

As shown in FIG. 5 , a first information channel, a second information channel and a third information channel may be formed between the accessory device 101 and the electronic device 102 .

The first information channel (ie the above wireless connection):

The wireless communication module 208 of the accessory device 101 and the wireless communication module 360 of the electronic device 102 have at least one communication processing module of the same type, and the wireless communication module 208 and the wireless communication module 360 establish the first information through the same type of communication processing module described above. aisle.

For example, assuming that the wireless communication module 208 includes a BLE module and the wireless communication module 360 also includes a BLE module, the wireless communication module 208 and the wireless communication module 360 can establish a BLE connection channel.

The accessory device 101 and the electronic device 102 may exchange wireless communication information through the first information channel. For example, the accessory device 101 can send pressure-sensitive information to the electronic device 102 through the first information channel, so that the electronic device 102 renders a handwriting effect according to the pressure-sensitive information; the electronic device 102 can send configuration information to the accessory device 101 through the first information channel.

The second information channel (ie the above-mentioned second communication connection):

The second information channel is a channel through which the signal transmitting circuit 205 of the accessory device 101 transmits a signal (PWM signal) to the screen of the electronic device 102 .

The second information channel may include a first sub-channel, and the first sub-channel is composed of one electrode included in the signal transmitting circuit 205 of the pen tip of the accessory device 101 and the screen of the electronic device 102 . The first sub-channel is used for the pen tip electrode of the accessory device 101 to cause the electrode of the signal transmitting circuit 205 to transmit a signal (eg, a PWM signal) to the screen of the electronic device 102 , and the signal is used for the electronic device 102 to obtain the report point information of the accessory device 101 . The principle is explained in detail below.

Referring to FIG. 6 , the in-screen touch sensor 380K of the electronic device 102 may include an X-axis electrode layer and a Y-axis electrode layer. The X-axis electrode layer may include a plurality of transmit (transmit, Tx) electrodes distributed in a matrix, and the Y-axis electrode layer may include a plurality of receive (receive, Rx) electrodes distributed in a matrix. The Tx electrodes and the Rx electrodes form a crisscross network, and the intersections (ie coordinate points) of the Tx electrodes and the Rx electrodes form a mutual capacitance (ie the capacitance formed by the Tx electrodes and the adjacent Rx electrodes).

When the electronic device 102 detects the mutual capacitance of each coordinate point on the touch sensor 380K, the touch chip connected to the touch sensor 380K can send an excitation signal to each Tx electrode in turn, and then the touch chip scans each receiving Rx electrode to receive an excitation signal. signal, convert the measured voltage value to digital signal and calculate the capacitance value.

The electronic device 102 detects the touch operation of the finger, and the principle of detecting the input content of the accessory device 101 is different.

When a finger touches the screen, the finger, the touch sensor 380K and the insulating material between them (such as the protective glass of the screen) can form a coupling capacitance, causing a slight change in current and a change in mutual capacitance. The electronic device 102 detects the change of the capacitance of the touch point by scanning the X-axis electrode matrix and the Y-axis electrode matrix, and calculates the position of the finger.

When the electronic device 102 enters the accessory device detection mode, that is, during the signal detection period of the working cycle of the electronic device 102, the Tx electrodes on the touch sensor 380K are converted into Rx electrodes, which alternate with the original Rx electrodes in the X and Y axes. The transmit signal of the accessory device 101 (eg, an active capacitive pen) is sensed. The signal received on the Tx electrode (which has been converted into Rx electrode) and the original Rx electrode can be amplified by the amplifying circuit of the touch chip. The numerical envelope composed of the amplitude value of the received signal (or the capacitance value of the X-axis and Y-axis) can be obtained on the X-axis electrode and the Y-axis electrode respectively, and the coordinates (x, y) of the signal receiving point can be obtained by calculation. , that is, the position point of the pen tip of the accessory device 101 on the screen, that is, reporting point information. For example, a calculation method can be performed by substituting the numerical envelope into the prior envelope model of the accessory device 101 . Those skilled in the art can understand that the calculation method can be a conventional solution in the field, and details are not repeated here. The touch chip transforms the signal from time-frequency to frequency domain, such as performing fast Fourier transform on the signal, to obtain the frequency of the signal sent by the accessory device 101 .

In some embodiments, the second information channel may further include a second sub-channel, which consists of one electrode included in the signal transmitting circuit 205 of the pen tip of the accessory device 101 and the screen of the electronic device 102 . The electrodes in the second subchannel are different from the electrodes in the first subchannel. The second sub-channel is used for the pen tip electrode of the accessory device 101 to transmit a signal (eg, a PWM signal) to the screen of the electronic device 102 . The signal transmitted by the second sub-channel, and the signal transmitted by the first sub-channel, are combined for the electronic device 102 to know the inclination of the accessory device 101 .

In the following embodiments of the present application, the signal transmitted by the first subchannel may be referred to as the first signal (or, the first signal may also be referred to as an alarm signal), and the signal transmitted by the second subchannel may be referred to as the second signal .

The third information channel (ie the above-mentioned first communication connection):

The third information channel is the channel through which the screen of the electronic device 102 transmits a signal (eg, a DSSS signal) to the signal detection circuit 206 of the accessory device 101 .

The third information channel consists of the screen of the electronic device 102 and one or more receive electrodes of the signal detection circuit 206 of the accessory device 101 .

Specifically, a signal, such as a signal modulated by DSSS, is sent by one or more Tx electrodes of the touch sensor 380K in the screen of the electronic device 102 and/or Tx electrodes converted from the Rx electrodes, and the signal is sent by the accessory device 101 One or more receiving electrodes of the pen tip receive. This signal may be referred to as an uplink signal, and the uplink signal is used for the accessory device 101 to obtain the device number of the electronic device 102 . Among them, the form of the device number can be set according to actual needs. For example, the device number can be a 2-bit or 3-bit binary number. When the device number is a binary number, the optional numbers can include four numbers: 00, 01, 10, and 11. The device number of the electronic device 102 may be a number arbitrarily selected from each optional number when the electronic device 102 is connected to the accessory device 101 for the first time; or, the device number of the electronic device 102 may be preset in the internal software system of the electronic device 102 Alternatively, the device number of the electronic device 102 may be a number designated by the user in the user interface of the electronic device 102 . The electronic device 102 can change the device number of the electronic device 102 through software upgrade or user setting. Before the number of the electronic device 102 is changed, the same device number is used when the electronic device 102 is connected to each accessory device 101 . It can be seen from the above that when the accessory device 101 writes on the electronic device 102, the uplink signal (eg DSSS signal) sent by the electronic device 102 to the accessory device 101, the signal sent by the accessory device 101 to the electronic device 102 (eg the first signal, the The two signals) are signals transmitted between the screen of the electronic device 102 and the pen tip of the accessory device 101 , and need to be detected or sent by the screen of the electronic device 102 or the pen tip of the accessory device 101 .

The following describes the mechanism of the pen tip of the accessory device 101 and the screen detection and signal transmission mechanism of the electronic device 102 .

In some embodiments, accessory device 101 may continuously transmit signals (eg, PWM signals), and may also continuously detect signals (eg, DSSS signals) transmitted by electronic device 102 .

In other embodiments, accessory device 101 may detect and transmit signals periodically, and transmit and detect may be separated in timing. That is, the accessory device 101 performs signal transmission and signal detection respectively in different time periods of the same cycle. In this way, interference between signals can be avoided, and the power of the accessory device 101 can be saved.

In some embodiments, the electronic device 102 may continuously transmit a signal (eg, a DSSS signal), and may also continuously detect a signal (eg, a PWM signal) transmitted by the accessory device 101 .

In other embodiments, the electronic device 102 may detect and transmit signals periodically, and may separate transmission and detection in timing. In this way, interference between signals can be avoided and the power of the electronic device 102 can be saved. When the accessory device 101 transmits two signals (ie, the first signal and the second signal) in one cycle, the two signals may have overlapping parts in timing, or may not overlap in timing. No restrictions apply.

Hereinafter, the device pairing method provided by the embodiments of the present application will be described in detail according to the device pairing systems shown in FIG. 1 to FIG. 6 and in combination with specific application scenarios.

1. The first pairing of the accessory device 101 and the electronic device 102 .

The pairing of the accessory device 101 and the electronic device 102 means that the accessory device 101 and the electronic device 102 mutually set each other as the default data transmission object. For example, assuming that the accessory device 101 is a stylus, the electronic device 102 includes a tablet computer 1 and a tablet computer 2, the stylus pen and the tablet computer 1 and the tablet computer 2 have established a first information channel, and the stylus pen is paired with the tablet computer 1, then the subsequent When the stylus detects the pressure-sensitive information, the stylus will transmit the pressure-sensitive information to the tablet computer 1 by default, and will not transmit the pressure-sensitive information to the tablet computer 2 by default.

When both the accessory device 101 and the electronic device 102 have the wireless communication function enabled, the accessory device 101 and the electronic device 102 can discover each other and establish a first information channel through the wireless communication module 208 and the wireless communication module 360 . After that, the accessory device 101 and the electronic device 102 can perform data interaction through the above-mentioned first information channel.

For example, referring to FIG. 7 , it is assumed that the accessory device 101 is a stylus, the electronic device 102 is a tablet computer, and both the wireless communication module 208 and the wireless communication module 360 include a Bluetooth module. The processor 201 of the stylus can be provided with a stylus driver 705, and the stylus driver 705 can perform data interaction with the Bluetooth module 706 of the stylus; the processor 310 of the tablet computer can include an application program 702, a stylus service 701 and an input In the system 703, the Bluetooth module of the tablet computer may include a Bluetooth protocol stack 704; after the Bluetooth module 706 of the stylus and the Bluetooth module of the tablet computer establish a Bluetooth connection channel, the stylus driver 705 can send data through the Bluetooth module 706 of the stylus To the Bluetooth protocol stack 704 of the tablet computer, the Bluetooth protocol stack 704 transmits the data to the stylus service 701, and the stylus service 701 transmits the data transmitted by the Bluetooth protocol stack 704 and the data transmitted by the application 702 to the input system 703 for processing; Alternatively, the stylus service 701 can also send data to the stylus Bluetooth module 706 through the Bluetooth protocol stack 704, and the stylus Bluetooth module 706 transmits the data transmitted by the Bluetooth protocol stack 704 to the stylus driver 705 for processing.

The process of establishing the first information channel between the accessory device 101 and the electronic device 102 for the first time may be the process of pairing the accessory device 101 and the electronic device 102 for the first time, or the process of establishing the first information channel between the accessory device 101 and the electronic device 102 for the first time may not be an accessory. The process of pairing the device 101 and the electronic device 102 for the first time.

For example, it is assumed that the accessory device A and the electronic device B have never established a first information channel and have never been paired.

At this time, if both the accessory device A and the electronic device B have enabled the wireless communication function, the accessory device A and the electronic device B can establish the first information channel for the first time, but the accessory device A and the electronic device B do not set each other as the default The information transmission object, accessory device A and electronic device B are not paired. In this case, the process of establishing the first information channel between the accessory device A and the electronic device B for the first time is not the process of pairing the accessory device A and the electronic device B for the first time.

Alternatively, the accessory device A and the electronic device B may perform the pairing operation for the first time in response to the user's operation. When performing the pairing operation, the accessory device A and the electronic device need to enable the wireless communication function to establish the first information channel, and set the other party as the default information transmission object. In this case, the first pairing process of the accessory device A and the electronic device B is the process of establishing the first information channel between the accessory device A and the electronic device B for the first time.

When the accessory device 101 and the electronic device 102 are paired for the first time, the accessory device 101 may be paired with the electronic device 102 according to a preset pairing manner.

In some possible implementations, the accessory device 101 and the electronic device 102 may be paired by magnetic pairing.

As shown in FIG. 8 , the accessory device 101 and the electronic device 102 may be provided with a magnetic attraction structure (for example, a Hall device) in a specific area. When the magnetic attraction structure of the accessory device 101 is close to the magnetic attraction structure of the electronic device 102 , the The magnetic attraction structure is attracted to the magnetic attraction structure of the electronic device 102 .

When the magnetic attraction structure of the accessory device 101 is adsorbed and connected to the magnetic attraction structure of the electronic device 102 , the pairing operation of the accessory device 101 and the electronic device 102 is triggered.

When the pairing operation is triggered, the electronic device 102 may display a prompt box on the display interface. For example, as shown in FIG. 8 , the electronic device 102 may display a prompt box on the display interface to prompt the user whether to connect with the accessory device 101 (ie, “My Stylus Pen”), and provide two options of “Connect” and “Cancel” .

Then, as shown in FIG. 9 , the electronic device 102 may send a first connection request to the accessory device 101 through the first information channel in response to the user's clicking operation on the “connection” option.

After receiving the first connection request, the accessory device 101 returns the first confirmation information to the electronic device 102 , completes the connection operation, and establishes a first information channel with the electronic device 102 . After that, the electronic device 102 and the accessory device 101 can perform data interaction through the first information channel.

The first connection request may include the device number of the electronic device 102 ; alternatively, the electronic device 102 may also send the device number of the electronic device 102 to the accessory device 101 after establishing the first information channel. After receiving the device number of the electronic device 102 , the accessory device saves the device number and wireless communication address of the electronic device 102 , and completes the first pairing of the accessory device 101 and the electronic device 102 .

In some other possible implementation manners, the accessory device 101 and the electronic device 102 may be paired by connection and pairing.

For example, referring to FIG. 10 and FIG. 11 , one end of the accessory device 101 may be provided with a pen cap, and the pen cap and the main body of the accessory device 101 are detachable connection structures. When the cap of the accessory device 101 is disassembled, the connecting head provided on the accessory device 101 can be viewed. The electronic device 102 may be provided with an interface. When the connector of the accessory device 101 is in contact with the interface of the electronic device 102, the pairing operation of the accessory device 101 and the electronic device 102 is triggered.

When the pairing operation is triggered, the electronic device 102 may display a prompt box on the display interface. For example, as shown in FIG. 11 , the electronic device 102 may display a prompt box on the display interface to prompt the user whether to connect with the accessory device 101 (ie, “My Stylus Pen”), and provide two options of “connect” and “cancel”.

After receiving the first connection request, the accessory device 101 returns the first confirmation information to the electronic device 102, completes the connection operation, and establishes a first information channel with the electronic device 102. After that, the electronic device 102 and the accessory device 101 can perform data interaction through the first information channel.

The types of the above connectors can be set according to actual needs. For example, the above connector may be any one of a Micro-B connector, a Universal Serial Bus (Universal Serial Bus, USB) Type-C connector, a Lightning connector and the like.

Correspondingly, the above-mentioned interface is an interface matched with the connector. For example, the above-mentioned interface can be any one of Micro-B interface, USB Type-C interface, Lightning interface and other interfaces.

In addition, each electronic device 102 may be provided with a corresponding device number. The device number of the electronic device 102 may be preset at the factory, or the device number of the electronic device 102 may also be user-defined.

The device numbers of the electronic devices 102 may be the same, or the device numbers of the electronic devices 102 may also be different.

It can be understood that although in the above example, the electronic device 102 transmits the device number of the electronic device 102 to the accessory device 101 during the first pairing process of the accessory device 101 and the electronic device 102 . However, in an actual application process, the electronic device 102 may not transmit the device number during the first pairing process.

For example, after the accessory device 101 and the electronic device 102 establish the first information channel for the first time, the electronic device 102 may transmit the device number of the electronic device 102 to the accessory device 101 through the first information channel.

That is to say, the accessory device 101 and the electronic device 102 may have never been paired, but the accessory device 101 and the electronic device 102 should have established the first information channel at least once, so that the electronic device 102 can pass its device number to the device through the first information channel. Accessory device 101 .

This embodiment of the present application does not impose any restrictions on the timing when the electronic device 102 transmits its device number to the accessory device 101 .

For ease of understanding, the above-mentioned process of first pairing the accessory device 101 with the electronic device 102 will be described below with reference to specific application scenarios.

Application Scenario 1:

In this embodiment, it is assumed that the accessory device 101 is a stylus and the electronic device 102 is a tablet computer. The stylus and the tablet are both provided with a magnetic attraction structure, and both the stylus and the tablet are provided with a BLE module.

When the accessory device 101 and the electronic device 102 are provided with a BLE module, the above-mentioned first information channel is a BLE connection channel. The BLE connection channel includes a Generic Attribute Profile (GATT) connection channel and a generic attribute-based Human Interface Device Interaction Protocol (HID Over Gatt Profile, HoGP) connection channel.

At this time, the fact that the accessory device 101 is connected to multiple electronic devices 102 means that the accessory device 101 establishes a GATT connection channel with the multiple electronic devices 102 . The pairing of the accessory device 101 and a certain electronic device 102 means that the accessory device 101 establishes a HoGP connection channel with the electronic device 102 .

A plurality of initial device numbers are preset in the tablet computer, and the tablet computer selects an initial device number from the initial device numbers as the device number of the tablet computer.

When both the stylus and the tablet have the Bluetooth BLE function turned on, the stylus and the tablet can discover each other and establish a GATT connection channel.

As shown in Figure 12, when a stylus and a tablet computer establish a GATT connection channel, they can interact based on GATT until the GATT connection channel is established.

For example, a stylus can send an advertising physical channel PDU to a tablet's BLE module by sending it to the BLE module. PDUs are protocol data units. The type of broadcast physical channel PDU can be ADV_IND PDU, AVD_EXT_IND PDU, AUX_ADV_IND PDU, AUX_SYNC_IND and other PDU messages.

After receiving the broadcast physical channel PDU, the tablet can send a scan request PDU (eg SCAN_REQ PDU) to the stylus.

After the stylus receives the scan request PDU, it returns the scan response PDU (eg SCAN_RSP PDU) to the tablet.

The tablet sends a connection request (CONNECT_IND) to the stylus to establish a GATT connection channel.

After that, the stylus and the tablet can communicate with each other by passing the Data Physical Channel PDU (Data Physical Channel PDU) through the GATT connection channel.

After the GATT connection channel is established, the stylus can read the screen type, device parameters and other information of the tablet computer based on the GATT connection channel. The tablet can pass the device number to the stylus based on the GATT connection channel.

As shown in FIG. 8 , when the magnetic attraction structure of the stylus is adsorbed and connected with the magnetic attraction structure of the tablet computer, the pairing operation of the stylus pen and the tablet computer is triggered.

At this point, if the stylus and the tablet are paired for the first time, a system prompt box will pop up on the display interface of the tablet, asking the user whether to connect with the stylus (ie, "My Stylus").

Then, the tablet computer can control the BLE module to send a first connection request to the stylus in response to the user's click operation on the "connect" option, the stylus pen returns the first confirmation information, and the tablet computer and the stylus establish a GATT connection. Then, based on the GATT connection, the tablet sends the device number to the stylus, and the stylus learns and stores the device number of the tablet.

Then, the stylus and the tablet establish a HoGP connection channel to complete the first pairing of the stylus and the tablet.

After the stylus and the tablet computer establish the HoGP connection channel, the service-related content specified in the protocol can be transmitted based on the HoGP. For example, the stylus can send pressure-sensitive information to the tablet computer through the HoGP connection channel based on the format and process of stylus transmission information specified in HoGP.

2. Use and switching of accessory equipment 101 .

As shown in FIG. 5 , when the accessory device 101 is in contact with the electronic device 102, the signal transmitting circuit 205 of the accessory device 101 can establish a second information channel with the screen of the electronic device 102, and the signal detecting circuit 206 of the accessory device 101 can communicate with the electronic device 102. The screen of 102 establishes a third information channel.

In addition, the accessory device 101 is provided with a pressure sensor 207. When the accessory device 101 is in contact with the electronic device 102, the pressure sensor 207 of the accessory device 101 can detect pressure-sensing information (hereinafter referred to as the pressure-sensing information currently detected by the accessory device 101 for short). is the first pressure-sensitive information).

As shown in FIG. 13 , the accessory device 101 can send an announcement signal to the touch sensor 380K of the electronic device 102 through the second information channel. The action of the accessory device 101 sending the announcement signal is called “announcement”.

The accessory device 101 may generate an announcement signal through a preset announcement signal generation method. For example, the accessory device 101 may generate an alarm signal through a pulse width modulation (Pulse Width Modulation, PWM) technology.

After the touch sensor 380K of the electronic device 102 receives the report signal, it can transmit the report signal to the processor 310, and the processor 310 performs frequency domain conversion on the report signal to obtain the frequency of the report signal. The frequency determines the type of announcing signal, and determines the pen tip position of the accessory device 101 according to the announcing signal, and then displays a corresponding handwriting effect at the pen tip position or responds to a touch command corresponding to the pen tip position.

Wherein, if the accessory device 101 does not detect other pressure-sensing information (hereinafter referred to as the second pressure-sensing information) within the first preset time period before detecting the first pressure-sensing information, the report sent by the accessory device 101 this time The point signal is determined to be the first point announcement signal, and the accessory device 101 records the first time when the first point announcement signal is sent.

When the electronic device 102 receives an announcement signal, if within the second preset time period before receiving the current announcement signal (hereinafter referred to as the first announcement signal), other announcement signals (hereinafter referred to as the first announcement signal) are not received. The second report signal), the electronic device 102 determines that the behavior of receiving the first report signal is the first time the report is received, and the electronic device 102 records the second time when the report is received for the first time.

The specific values of the first preset duration and the second preset duration may be set according to actual requirements. For example, according to research, when the user uses the accessory device 101 on different electronic devices 102, the switching time spent by the user each time switching the object of use of the accessory device 101 is usually greater than 500 ms. Therefore, the first preset time duration can be and the second preset duration is set to 500ms.

Moreover, the first preset duration may be consistent with the second preset duration, or, the first preset duration may also be inconsistent with the second preset duration. For example, both the first preset duration and the second preset duration may be set to 500ms; or, the first preset duration may be set to 500ms, and the second preset duration may be set to 510ms.

In addition, the electronic device 102 may periodically generate an uplink signal, and send the uplink signal to the signal detection circuit 206 of the accessory device 101 through the above-mentioned third information channel.

The uplink signal is used to transmit the device number of the electronic device 102 , and the accessory device 101 can determine whether the accessory 101 has approached the electronic device 102 by detecting the uplink signal. The electronic device 102 may generate an uplink signal according to a preset uplink signal generation manner. For example, the electronic device 102 may generate the above-mentioned uplink signal by using a direct sequence spread spectrum (Direct Sequence Spread Spectrum, DSSS) technology.

After receiving the uplink signal, the signal detection circuit 206 of the accessory device 101 transmits the uplink signal to the processor 201, and the processor 201 performs frequency domain conversion on the uplink signal to obtain the frequency of the uplink signal, and determines the frequency of the uplink signal according to the frequency of the uplink signal. type. In addition, the processor 201 can analyze the uplink signal to obtain the device number of the electronic device 102 .

It should be noted that the above-mentioned second information channel and third information channel may be two different information channels, and in this case, the second information channel and the third information channel are composed of different electrodes. Alternatively, the second information channel and the third information channel may be the same information channel, and in this case, the second information channel and the third information channel are composed of the same electrodes.

When the second information channel and the third information channel are the same information channel, the accessory device 101 and the electronic device 102 transmit the point announcement signal and the uplink signal through the same information channel.

After receiving the point report signal, the electronic device 102 needs to determine the position of the pen tip of the accessory device 101 according to the point report signal, and render the handwriting effect at the position of the pen point. Therefore, the accessory device 101 needs to transmit the pressure-sensitive information to the electronic device 102, so that the electronic device 102 renders the handwriting effect according to the pressure-sensitive information.

For example, as shown in FIG. 14 , assuming that the accessory device 101 is a stylus 1401 and the electronic device 102 is a tablet computer 1402, when the stylus 1011 is written on the tablet 1402 by the user with different strengths, the pressure sensor of the stylus 1401 207 can detect different pressure-sensitive information, the stylus 1011 transmits the pressure-sensitive information to the tablet computer 1402, and the tablet computer 1402 renders the thickness of the handwriting according to the pressure-sensitive information. The greater the pressure-sensitive information, the thicker the handwriting.

When the user uses the accessory device 101 on a plurality of electronic devices 102 , it takes a certain period of time to switch each time the object of use of the accessory device 101 is switched.

For example, as shown in FIG. 15 and FIG. 16 , at the initial moment, the stylus 1501 establishes a GATT connection channel with the tablet computer 1502 and the tablet computer 1503, and the tablet computer 1502 and the tablet computer 1503 send their respective device numbers to the stylus 1501. When the user uses the stylus 1501 on the tablet computer 1502, the tablet computer 1502 and the stylus 1501 establish a HoGP connection channel. After that, if the user wants to use the stylus 1501 on the tablet computer 1503, the user can move the stylus 1501 from the tablet computer 1502 to the tablet computer 1503, then the stylus 1501 disconnects the HoGP connection channel with the tablet computer 1502 and keeps the GATT connection channel (basic data connection channel), the stylus and the tablet computer 1503 establish a HoGP connection channel. The process of the user moving the stylus 1501 from the tablet computer 1502 to the tablet computer 1503 takes a certain amount of time, that is, the switching time.

Therefore, the accessory device 101 can determine whether the default device needs to be re-determined according to the above-mentioned first preset duration. The default device is the electronic device 102 currently paired with the accessory device 101 . For example, when the above-mentioned first information channel is a BLE connection channel, the default device is the electronic device 102 that has established a HoGP connection channel with the accessory device 101 .

If the accessory device 101 has detected the second pressure-sensing information within the first preset period of time before detecting the first pressure-sensing information, it means that the time interval between the accessory device 101 detecting the pressure-sensing information twice is not long enough for the accessory device 101 to detect the pressure-sensing information twice. When the user switches the use object of the accessory device 101, the accessory device 101 does not switch the default device, and sends the pressure-sensitive signal to the default device through the first information channel. The pressure-sensitive signal includes first pressure-sensitive information, and the default device can render a handwriting effect according to the first pressure-sensitive information.

If the accessory device 101 has not detected the second pressure-sensing information within the first preset time period before detecting the first pressure-sensing information, it means that the target device may not be the default device. The target device is the electronic device 102 that the accessory device 101 actually contacts.

At this time, the accessory device 101 needs to identify the target device according to the target device number, pair with the target device, and set the target device as a new default device. The target device number is the device number of the target device, and the target device number can be obtained by parsing the above-mentioned uplink signal by the accessory device 101 .

When the accessory device 101 parses the target device number, the following situations exist:

2.1. The target device number is the device number of the default device, and among the verification devices, only the default device matches the target device number.

The verification device is the electronic device 102 that currently establishes the first information channel with the accessory device 101 .

Since the device numbers of each electronic device 102 may be the same device number, when the target device number is the device number of the default device, the target device may be the default device, or the target device may not be the default device.

At this time, the accessory device 101 may acquire the device numbers of each verification device (ie, the first device number), and determine whether there are multiple verification devices whose device numbers match the target device numbers. Wherein, the verification device includes a default device.

If only the device number of the default device matches the target device number among the verification devices, it means that the target device is the default device. At this time, the accessory device 101 does not switch the default device, and sends a pressure-sensitive signal to the default device.

The pressure-sensitive signal includes the above-mentioned first pressure-sensitive information. After receiving the first pressure-sensitivity information, the default device may render a handwriting effect at the position of the pen tip according to the first pressure-sensitivity information.

2.2. The target device number is the device number of the default device, and there are multiple matching devices in the verification device, or the target device number is not the device number of the default device, but there is a matching device.

The matching device is the authentication device that matches the target device number.

If the target device number is the default device number and there are multiple matching devices in the verification device, or if the target device number is a device number that is not the default device, but there is a matching device, the accessory device 101 cannot directly identify the target from the matching device equipment.

At this time, the accessory device 101 may send the first consultation information to each matching device.

The content of the first consultation information may be set according to the actual situation. For example, the first consultation information may include the first point identification and the first time.

In some possible implementations, the accessory device 101 may synchronously send the above-mentioned first consultation information to each matching device through the first information channel.

After the matching device receives the first consultation information, the matching device can determine whether the last time announcing signal is received for the first time, and calculate the deviation between the second time locally recorded by the device and the first time.

If the last time the matching device receives an announcement signal is not the first time, the matching device does not record the second time, or the above deviation value is greater than or equal to the preset deviation threshold, the matching device returns pairing failure information to the accessory device 101 .

If the last time the matching device receives the report signal is the first time the report is received, and the deviation value is less than the preset deviation threshold, the matching device returns pairing confirmation information to the accessory device 101 .

The above-mentioned preset deviation threshold can be set according to actual needs. For example, in some embodiments, it is found through statistics that the sum of the time consumed by the accessory device 101 to transmit the alarm signal and the time consumed by the electronic device 102 to process the alarm signal is less than 2ms, then the user can set the preset deviation threshold to 2ms Alternatively, in other embodiments, the user may also set the preset deviation threshold to values such as 1ms, 3ms, and 5ms according to other influencing factors.

After the accessory device 101 can send the first consultation information to each matching device, if the accessory device 101 receives the pairing confirmation information returned by any matching device, the accessory device 101 confirms the matching device that sent the pairing confirmation information as the target device, and matches the target device with the target device. Device pairing sets the target device as the new default device. For example, when the above-mentioned first information channel is a BLE connection channel, after the accessory device 101 confirms the matching device that sent the pairing confirmation information as the target device, the accessory device 101 pairs with the target device, that is, the accessory device 101 establishes a HoGP connection channel with the target device , set the target device as the new default device.

It should be noted that in the process of engineering practice, it is difficult for electronic equipment to start executing multiple tasks at the same time. If the time when electronic equipment starts to execute multiple tasks is within a certain error range, it can be regarded as electronic equipment synchronization. Start multiple tasks. Therefore, when the accessory device 101 sends the first consultation information to each matching device synchronously, it can be understood that the time when the accessory device 101 sends the first consultation information to each matching device is within a preset error range. The error range can be set according to the actual situation.

Application Scenario Two:

Referring to FIG. 17 , in the scenario shown in FIG. 17 , the accessory device 101 includes a stylus 1701 , and the electronic device 102 includes a tablet computer 1702 , a tablet computer 1703 , and a tablet computer 1704 .

On the stylus 1701, a Bluetooth module 17011 is provided; on the tablet computer 1702, a Bluetooth module 17021 is provided; on the tablet computer 1703, a Bluetooth module 17031 is provided; on the tablet computer 1704, a Bluetooth module 17041 is provided.

At the first moment, the stylus 1701 is paired with the tablet computer 1703, the stylus 1701 writes on the tablet computer 1703, and the Bluetooth module 17011 of the stylus 1701 establishes a HoGP connection channel with the Bluetooth module 17031 of the tablet computer 1703.

The Bluetooth module 17011 of the stylus 1701 establishes a GATT connection channel with the Bluetooth module 17021 of the tablet computer 1702 and the Bluetooth module 17041 of the tablet computer 1704 respectively.

As shown in FIG. 18 , at the second moment, the stylus 1701 is moved to the tablet computer 1702 , and in response to the user's operation, writes on the tablet computer 1702 and contacts the tablet computer 1702 .

When the stylus 1701 is in contact with the tablet computer 1702, the stylus 1701 sends the first point signal to the tablet computer 1702 through the second information channel, and the tablet computer 1702 sends the uplink signal to the stylus 1701 through the third information channel.

The pressure sensor 207 of the stylus 1701 detects the first pressure-sensing information, and the stylus 1701 does not detect the second pressure-sensing information within the first preset time period before detecting the first pressure-sensing information, so the stylus 1701 records The first time at which the first point signal is sent.

The tablet computer 1702 receives the first point notification signal, and the tablet computer 1702 does not detect the second point notification signal within the second preset time period before receiving the first point notification signal, so the tablet computer 1702 will receive the first point notification signal. The point signal is determined to be the first time announcing point is received, and the second time of first receiving announcing point is recorded.

Since the stylus 1701 does not detect the second pressure-sensing information within the first preset time period before detecting the first pressure-sensing information, the stylus 1701 parses the uplink signal to obtain the target device number.

At this time, according to the target device number, the stylus 1701 determines that the tablet computer 1702 , the tablet computer 1703 , and the tablet computer 1704 all match the target device number.

Therefore, the stylus 1701 sends the first consultation information to the tablet computer 1702 , the tablet computer 1703 and the tablet computer 1704 synchronously. The first consultation information includes the first point identifier and the first time.

After receiving the first consultation information, the tablet computer 1702 detects that the last time announcing signal is received for the first time, and then obtains the second time, subtracts the first time from the second time, and obtains the difference between the second time and the first time. Deviation.

When the tablet computer 1702 detects that the deviation value is smaller than the preset deviation threshold, it returns a pairing confirmation message to the stylus 1701 .

After the tablet computer 1703 and the tablet computer 1704 receive the first consultation information, since the last time the tablet computer 1703 and the tablet computer 1704 received the report point signal is not the first time to receive the report point, the tablet computer 1703 returns a pairing failure message to the stylus 1701 , the tablet computer 1704 returns a pairing failure message to the stylus 1701 .

After receiving the pairing confirmation message sent by the tablet computer 1702, the stylus 1701 determines the tablet computer 1702 as the target device, establishes a HoGP connection channel with the tablet computer 1702, sets the tablet computer 1702 as the new default device, and sends the pairing instruction information to the tablet computer Computer 1702. After receiving the pairing instruction information, the tablet computer 1702 completes the pairing operation with the stylus 1701 .

After the stylus 1701 and the tablet computer 1702 establish a HoGP connection channel, the stylus 1701 sends the first pressure-sensitive information to the tablet computer 1702, and the tablet computer 1702 renders a handwriting effect according to the first pressure-sensitive information.

In some other possible implementation manners, the accessory device 101 may determine the polling sequence of each matching device according to the first preset rule, and poll each matching device in turn according to the polling sequence.

The first preset rule can be set according to actual needs. For example, in some embodiments, the first preset rule may be set to determine the polling order of each matching device according to the time when each matching device and the accessory device 101 establish the first information channel, and sorting in order from near to far. . In other embodiments, the first preset rule may be set to be sorted according to the time when each matching device has been set as the default device, in order from near to far, and the matching device that has not been set as the default device is sorted according to The time for establishing the first information channel between each matching device and the accessory device 101 is sorted in order from near to far, so as to determine the polling sequence of each matching device.

After determining the polling sequence of each matching device, the accessory device 101 sequentially sends the first consultation information to each matching device according to the polling sequence.

If the accessory device 101 receives the pairing failure information sent by the matching device, it sends the first consultation information to the next matching device according to the polling sequence.

If the accessory device 101 receives pairing confirmation information sent by the matching device, it stops polling, determines the matching device that sent the pairing confirmation information as the target device, pairs with the target device, and sets the target device as a new default device.

Application scenario three:

Referring to FIG. 19 , in the scenario shown in FIG. 19 , the accessory device 101 includes a stylus 1901 , and the electronic device 102 includes a tablet computer 1902 and a tablet computer 1903 .

On the stylus 1901, a Bluetooth module 19011 is provided; on the tablet computer 1902, a Bluetooth module 19021 is provided; on the tablet computer 1903, a Bluetooth module 19031 is provided.

At the third moment, the stylus 1901 is paired with the tablet computer 1903, the stylus 1901 writes on the tablet computer 1903, and the Bluetooth module 19011 of the stylus 1901 establishes a HoGP connection channel with the Bluetooth module 19031 of the tablet computer 1903.

The Bluetooth module 19011 of the stylus 1901 and the Bluetooth module 19021 of the tablet computer 1902 establish a GATT connection channel.

At the fourth moment, the stylus 1901 is moved to the tablet computer 1902, and in response to the user's operation, writes on the tablet computer 1902 and contacts the tablet computer 1902.

When the stylus 1901 is in contact with the tablet computer 1902, the stylus 1901 sends the first point signal to the tablet computer 1902 through the second information channel, and the tablet computer 1902 sends the uplink signal to the stylus 1901 through the third information channel.

The pressure sensor 207 of the stylus 1901 detects the first pressure-sensitive information, and the stylus 1901 does not detect the second pressure-sensitive information within the first preset time period before detecting the first pressure-sensitive information, so the stylus 1901 records The first time at which the first point signal is sent.

The tablet computer 1902 receives the first report signal, and the tablet computer 1902 does not detect the second report signal within the second preset time period before receiving the first report signal, so the tablet computer 1902 will receive the first report. The point signal is determined to be the first time announcing point is received, and the second time of first receiving announcing point is recorded.

Since the stylus 1901 does not detect the second pressure-sensing information within the first preset time period before detecting the first pressure-sensing information, the stylus 1901 parses the uplink signal to obtain the target device number.

At this time, the stylus 1901 determines that both the tablet computer 1902 and the tablet computer 1903 match the target device number according to the target device number.

Since there are multiple matching devices, the stylus 1901 determines the polling order of the tablet computer 1902 and the tablet computer 1903 according to the first preset rule.

The first preset rule is that the stylus 1901 sorts according to the time when each matching device has been set as the default device, according to the order from near to far. The time of establishing the first information channel with the stylus 1901 is sorted in order from near to far, so as to determine the polling order of each matching device.

Since the tablet computer 1903 is the default device currently paired with the stylus 1901 , the polling sequence of the tablet computer 1902 and the tablet computer 1903 is to query the tablet computer 1903 first, and then query the tablet computer 1902 .

Therefore, the stylus 1901 sends the first consultation information to the tablet computer 1903 first. The first consultation information includes the first point identifier and the first time.

As shown in FIG. 20 , after the tablet computer 1903 receives the first consultation information, it detects that the last time the tablet computer 1903 received an announcement signal is not the first time to receive an announcement. Therefore, the tablet computer 1903 returns a pairing failure message to the stylus 1901 .

After receiving the pairing failure information returned by the tablet computer 1903, the stylus pen 1901 sends the first consultation information to the tablet computer 1902 according to the above polling sequence.

After receiving the first consultation information, the tablet computer 1902 detects that the last time announcing signal is received for the first time, and then obtains the second time, subtracts the first time from the second time, and obtains the difference between the second time and the first time. Deviation.

As shown in FIG. 21 , when the tablet computer 1902 detects that the deviation value is smaller than the preset deviation threshold, it returns a pairing confirmation message to the stylus 1901, and renders the handwriting effect according to the first pressure-sensitive information.

After receiving the pairing confirmation message sent by the tablet computer 1902, the stylus 1901 determines the tablet computer 1902 as the target device, establishes a HoGP connection channel with the tablet computer 1902, sets the tablet computer 1902 as the new default device, and sends the pairing instruction information to the tablet computer Computer 1902. After receiving the pairing instruction information, the tablet computer 1902 completes the pairing operation with the stylus 1901 .

After the stylus 1901 and the tablet computer 1902 establish a HoGP connection channel, the stylus 1901 sends the first pressure-sensitive information to the tablet computer 1902, and the tablet computer 1902 renders the handwriting effect according to the first pressure-sensitive information.

If the accessory device 101 has inquired about all matching devices and still does not receive the pairing confirmation message, it means that the target device may not have the wireless communication function enabled, so that the accessory device 101 cannot establish the first information channel with the target device.

At this time, the accessory device 101 may perform a preset prompt operation, and remind the user to enable the wireless communication function of the target device through the preset prompt operation.

The content of the preset prompt operation can be set according to the actual situation. Specifically, the preset prompting operation may be any one or a combination of any one or a combination of prompting methods such as vibration, buzzer sounding, and speaker voice broadcast.

For example, as shown in FIG. 22 , it is assumed that the stylus 2201 is writing on the tablet computer 2202, and the tablet computer 2202 does not have the Bluetooth function enabled, so that the stylus 2201 cannot find the target device. At this time, the stylus 2201 can remind the user to turn on the Bluetooth function of the tablet computer 2202 by means of vibration; or, as shown in FIG. 23 , when the stylus 2201 is provided with a buzzer, the stylus 2201 can also control the buzzer to emit The sound of "di" reminds the user to turn on the Bluetooth function of the tablet computer 2202; or, as shown in Figure 24, when the stylus 2201 is provided with a speaker, the stylus 2201 can also control the speaker to broadcast "Please turn on the Bluetooth function", In this way, the user is reminded to turn on the Bluetooth function of the tablet computer 2202 .

Application scenario four:

Referring to FIG. 25 , in the scenario shown in FIG. 25 , the accessory device 101 includes a stylus 2501 and a stylus 2502 , and the electronic device 102 includes a mobile phone 2503 and a tablet computer 2504 .

The stylus 2501 is provided with a Bluetooth module 25011; the stylus 2502 is provided with a Bluetooth module 25021; the mobile phone 2503 is provided with a Bluetooth module 25031; and the tablet computer 2504 is provided with a Bluetooth module 25041.

At the fifth moment, the stylus 2501 is paired with the mobile phone 2503, the stylus 2501 writes on the mobile phone 2503, and the Bluetooth module 25011 of the stylus 2501 establishes a HoGP connection channel with the Bluetooth module 25031 of the mobile phone 2503.

The Bluetooth module 25011 of the stylus 2501 and the Bluetooth module 25041 of the tablet computer 2504 establish a GATT connection channel.

The stylus 2502 is paired with the tablet computer 2504, the stylus 2502 writes on the tablet computer 2504, and the Bluetooth module 25021 of the stylus 2502 establishes a HoGP connection channel with the Bluetooth module 25041 of the tablet computer 2504.

The Bluetooth module 25021 of the stylus 2502 and the Bluetooth module 25031 of the mobile phone 2503 establish a GATT connection channel.

After that, the stylus 2501 leaves the mobile phone 2503, and the stylus 2502 leaves the tablet 2504.

As shown in FIG. 26, at the sixth moment, the stylus 2502 is moved to the mobile phone 2503, and in response to the user's operation, writes on the mobile phone 2503 and contacts the mobile phone 2503.

When the stylus 2502 is in contact with the mobile phone 2503, the stylus 2502 sends the report signal 1 to the mobile phone 2503 through the second information channel, and the mobile phone 2503 sends the uplink signal 1 to the stylus 2502 through the third information channel.

The pressure sensor of the stylus 2502 detects the pressure-sensitive information 1, and the stylus 2502 does not detect other pressure-sensitive information within the first preset time period before detecting the pressure-sensitive information 1, so the stylus 2502 records and sends the report point signal 1 at time T1.

The mobile phone 2503 receives the report signal 1, and the mobile phone 2503 does not detect other report signals within the second preset time period before receiving the report signal 1, so the mobile phone 2503 determines that the report signal 1 is received for the first time. point, and record the time T2 when the point is first received.

Since the stylus 2502 does not detect other pressure-sensitive information within the first preset time period before detecting the pressure-sensitive information 1, the stylus 2502 parses the uplink signal 1 to obtain the target device number 1.

At this time, according to the target device number 1, the stylus 2502 determines that both the mobile phone 2503 and the tablet computer 2504 match the target device number 1.

Therefore, the stylus 2502 sends consultation information 1 to the mobile phone 2503 and the tablet computer 2504. The consultation information 1 includes the first point identifier and the time T1.

After the mobile phone 2503 receives the consultation information 1, it detects that the last received report signal is the received report signal 1, and the received report signal 1 is the first time to receive the report. Therefore, the mobile phone 2503 obtains the time T2 and subtracts the time T1 from the time T2. , the first deviation value between time T2 and time T1 is obtained.

When the mobile phone 2503 detects that the first deviation value is smaller than the preset deviation threshold, it returns a pairing confirmation message to the stylus 2503 .

After the tablet computer 2504 receives the consultation information 1, it detects that the last time the tablet computer 2504 receives an announcement signal is not the first time to receive an announcement. Therefore, the tablet computer 2504 returns a pairing failure message to the stylus 2502.

After the stylus 2502 receives the pairing confirmation message sent by the mobile phone 2503, it determines the mobile phone 2503 as the target device, pairs with the mobile phone 2503, sets the mobile phone 2503 as the new default device, establishes a HoGP connection channel with the mobile phone 2503, and sends the pairing instruction information to Phone 2503. After receiving the pairing instruction information, the mobile phone 2503 completes the pairing operation with the stylus 2502 .

After the stylus 2502 and the mobile phone 2503 establish a HoGP connection channel, the stylus 2502 sends the pressure sensitive information 1 to the mobile phone 2503 , and the mobile phone 2503 renders the handwriting effect according to the pressure sensitive information 1 .

As shown in FIG. 27 , at the seventh moment, the stylus 2501 is moved to the tablet computer 2504 , and in response to the user's operation, writes on the tablet computer 2504 and contacts the tablet computer 2504 .

When the stylus 2501 is in contact with the tablet computer 2504, the stylus 2501 sends an announcement signal 2 to the tablet computer 2504 through the AC connection channel, and the tablet computer 2504 sends the uplink signal 2 to the stylus pen 2501 through the AC connection channel.

The pressure sensor of the stylus 2501 detects the pressure-sensitive information 2, and the stylus 2501 does not detect other pressure-sensitive information within the first preset period of time before detecting the pressure-sensitive information 2, so the stylus 2501 records and sends the reporting point signal 2 at time T3.

The tablet computer 2504 receives the reporting point signal 2, and the tablet computer 2504 does not detect other reporting point signals within the second preset time period before receiving the reporting point signal 2, so the tablet computer 2504 determines that the received reporting point signal 2 is the first. Receive the report point for the second time, and record the time T4 when the report point is received for the first time.

Since the stylus 2501 does not detect other pressure-sensitive information within the first preset time period before detecting the pressure-sensitive information 2 , the stylus 2501 parses the uplink signal 2 to obtain the target device number 1 .

At this time, according to the target device number 1, the stylus 2501 determines that both the mobile phone 2503 and the tablet computer 2504 match the target device number 1.

Therefore, the stylus 2501 sends the consultation information 2 to the mobile phone 2503 and the tablet computer 2504 through the above. The consultation information 2 includes the first point identifier and the time T3.

Since the stylus pen 2502 writes on the mobile phone 2503, after the mobile phone 2503 receives the consultation information 2, it detects that the last time the mobile phone 2503 receives the report signal is not the first time to receive the report, so the mobile phone 2503 returns a pairing failure message to the stylus 2501 .

After the tablet computer 2504 receives the consultation information 2, it detects that the last received report signal is the received report signal 2, and the received report signal 2 is the first time to receive the report. Therefore, the tablet computer 2504 obtains the time T4 and subtracts the time T4 from the time T4. At time T3, a second deviation value between time T4 and time T3 is obtained.

When the tablet computer 2504 detects that the second deviation value is smaller than the preset deviation threshold, it returns a pairing confirmation message to the stylus 2504 .

After receiving the pairing confirmation message sent by the tablet computer 2504, the stylus 2501 determines the tablet computer 2504 as the target device, pairs with the tablet computer 2504, sets the tablet computer 2504 as the new default device, and establishes a HoGP connection channel with the tablet computer 2504. Send pairing instructions to tablet 2504. After receiving the pairing instruction information, the tablet computer 2504 completes the pairing operation with the stylus 2501 .

After the stylus 2502 and the tablet computer 2504 establish a HoGP connection channel, the stylus 2502 sends the pressure-sensitive information 2 to the tablet computer 2504 , and the tablet computer 2504 renders the handwriting effect according to the pressure-sensitive information 2 .

2.3. The target device number is not the device number of the default device, and there is no matching device in the verification device.

If the target device number is not the device number of the default device, and there is no matching device in the verification device, it means that the target device number does not match each verification device.

For example, it is assumed that device number 1 and device number 2 are stored in accessory device A.

Suppose accessory device A is writing on the default device. The default device changed the device number from device number 1 to device number 3 and did not notify accessory device A. At this time, the target device number obtained by accessory device A is device number 3, but accessory device A does not record device number 3. Therefore, accessory device A determines that the target device number is not the device number of the default device, and there is no match in the verification device. equipment.

Alternatively, the device number of the electronic device B is device number 3, and the wireless communication function is not enabled for the electronic device B. At this time, the accessory device A writes on the electronic device B, and the obtained target device number is device number 3. However, the electronic device B has never been connected to the accessory device A, and the wireless communication function is not currently enabled. Therefore, the accessory device A has never recorded the device number 3, so the accessory device determines that the target device number is not the device number of the default device, and verifies the device number in the device. No matching device exists.

In some possible implementations, when the target device number does not match each verification device, the accessory device 101 may directly determine the current default device as the target device without switching the default device, and send a pressure-sensitive signal to the default device.

After receiving the pressure-sensitive signal, the default device renders a handwriting effect according to the first pressure-sensitive information in the pressure-sensitive signal.

In other possible implementation manners, when the target device number does not match each verification device, the accessory device 101 may also perform a preset prompt operation to remind the user to enable the wireless communication function of the target device through the preset prompt operation.

To sum up, in the device pairing method provided in this embodiment, when the accessory device 101 and the electronic device 102 are in contact, the electronic device 102 can transmit an uplink signal to the accessory device 101 through the third information channel. The target device number of the electronic device 102 is included in the uplink signal. The accessory device 101 can determine whether the default device needs to be switched according to the target device number. When the accessory device 101 needs to switch the default device, it can send the first consultation information to the corresponding electronic device 102 according to the target device number, thereby identifying the target device, pairing with the target device, and setting the target device as a new default device. During the process of the accessory device 101 switching the paired default device, the accessory device 101 can determine whether to switch the paired electronic device 102 and identify the target device by itself. This process does not require the user to actively perform a specific pairing operation, which improves the ability of the accessory device 101 to switch the use object. The fluency, and strong ease of use and practicability, improve the user experience.

It should be understood that the size of the sequence numbers of the steps in the above embodiments does not mean the sequence of execution, and the execution sequence of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

Hereinafter, another device pairing method provided by an embodiment of the present application will be described in detail from the perspective of an accessory device. Referring to FIG. 28, the device pairing method provided by this embodiment includes:

S2801, the accessory device is in contact with the electronic device.

When the accessory device is in contact with the electronic device, the pressure sensor of the accessory device detects the first pressure-sensitive information, and the signal transmitting circuit of the accessory device can establish a second information channel with the screen of the electronic device, and the signal detection circuit of the accessory device can A third information channel is established with the screen of the electronic device.

At this time, the accessory device can send the first point announcement signal to the electronic device through the second information channel, and the electronic device sends the uplink signal to the accessory device through the third information channel.

After receiving the first report signal, the electronic device can determine the position of the pen tip according to the first report signal, and then render the handwriting effect at the position of the pen tip or respond to the touch command corresponding to the position of the pen tip.

After the accessory device receives the uplink signal, it can parse the uplink signal to obtain the target device number of the target device (ie, the electronic device currently in contact with the accessory device).

S2802. The accessory device determines whether the second pressure-sensing information is not detected within the first preset time period before the first pressure-sensing information is detected, and if so, executes S2803, and if not, executes S2805.

When the accessory device detects the first pressure-sensing information, it may detect whether other pressure-sensing information, that is, the second pressure-sensing information, has been detected in the previous first preset time period.

If the accessory device has detected the second pressure-sensing information within the first preset period of time before the first pressure-sensing information is detected, it means that the time interval between the accessory device detecting the pressure-sensing information twice adjacently is not enough for the user to switch the accessory The use object of the device, the target device is the electronic device currently paired with the accessory device (ie the default device). At this time, the accessory device executes S2805.

For example, it is assumed that the accessory device has detected the second pressure-sensitivity information within a first preset time period before detecting the first pressure-sensitivity information, and the time when the accessory device detected the first pressure-sensitivity information is the same as when the second pressure-sensitivity information was detected. The time interval is 87ms, and 87ms is not enough for the user to change the use object of the accessory device. At this time, the accessory device can determine that the user has not changed the use object of the accessory device, and the target object is still the default device.

If the accessory device does not detect the second pressure-sensing information within the first preset time period before detecting the first pressure-sensing information, it indicates that the target device may not be the default device.

For example, it is assumed that the first preset duration is set to 500ms. If the accessory device does not detect the second pressure-sensing information within 500ms before detecting the first pressure-sensing information, it means that the interval between the user's current use of the accessory device and the last time the user used the accessory device is sufficient for the user to replace the accessory device object of use. At this time, the target device may still be the default device, that is, the user is still using the accessory device on the same electronic device; or, the target device may not be the default device, that is, the user has moved the accessory device to another electronic device for use.

At this time, the accessory device records the first time when the first pressure-sensing information is detected, and executes S2803.

S2803, the accessory device determines whether the target device number can be obtained by analysis, if so, execute S2804, and if not, execute S2814.

If the accessory device does not detect the second pressure-sensing information within the first preset time period before detecting the first pressure-sensing information, the accessory device parses the uplink signal to determine whether the target device number can be obtained by parsing.

If the accessory device cannot parse the target device number, it may be that the accessory support function (such as the stylus function) is not enabled on the target device. Therefore, the target device does not transmit the uplink signal to the accessory device, and the accessory device cannot receive the uplink signal and cannot connect to the accessory device. The upstream signal is parsed, and the target device number cannot be obtained. Therefore, the accessory device executes S2814.

If the accessory device can obtain the target device number by parsing, S2804 is executed.

S2804, the accessory device determines whether there is a verification device matching the target device number, if yes, execute S2806, and if not, execute S2805.

The verification device is the electronic device that currently establishes the first information channel with the accessory device. Validation devices include default devices.

After acquiring the target device number, the accessory device can acquire the device number of each verification device to determine whether there is a verification device matching the target device number. The matching between the verification device and the target device means that the device number of the verification device is consistent with the target device number.

If there is an authentication device matching the target device number, the paired device executes S2806.

If there is no verification device matching the target device number, the accessory device executes S2805 without switching the default device.

S2805, the accessory device does not switch the default device.

In step S2805, the accessory device determines the current default device as the target device, and does not switch the default device.

At this time, the accessory device can send the pressure-sensitive signal to the default device through the first information channel.

The pressure-sensitive signal includes first pressure-sensitive information, and after receiving the pressure-sensitive signal, the default device can render the handwriting effect at the position of the pen tip according to the first pressure-sensitive information in the pressure-sensitive signal.

S2806 , the accessory device determines whether the target device number is the device number of the default device, and if so, executes S2807 , and if not, executes S2808 .

After the accessory device detects that there is a verification device matching the target device number, the accessory device can determine whether the target device number is the device number of the default device.

If the target device number is the device number of the default device, it means that the target device may be the default device, and at this time, the accessory device executes S2807.

If the target device number is not the device number of the default device, it means that the target device is not the default device, and at this time, the accessory device executes S2808.

S2807, the accessory device determines whether there is only one matching device in the verification device, if so, execute S2805, and if not, execute S2809.

After the accessory device determines that the target device number is the device number of the default device, it can determine whether there is only one matching device in the verification device. The matching device is the authentication device that matches the target device number.

Since the default device is also the verification device, if there is only one matching device in the verification device, it means that only the device number of the default device in the verification device is the target device number.

At this time, the accessory device can determine that the target device is the default device, so the accessory device does not need to switch the default device, and S2805 is executed.

If there are multiple matching devices in the verification device, it means that the target device may be the default device, or the target device may not be the default device, and the accessory device cannot directly identify the target device from the matching device.

At this time, the accessory device may execute S2809 to query the default device first.

S2808. The accessory device determines the polling sequence of each matching device according to the first preset rule, sends the first consultation information to each matching device in turn according to the polling sequence, and then executes S2811.

When the target device number is not the device number of the default device, or, when the target device number is the device number of the default device and there are multiple matches, the accessory device cannot directly identify the target device from the matching devices.

Therefore, the accessory device can determine the polling sequence of each matching device according to the first preset rule, send the first consultation information to each matching device in turn according to the polling sequence, and identify the target device according to the information returned by the matching device.

The first preset rule can be set according to actual needs. For example, in some embodiments, the first preset rule may be set to determine the polling order of each matching device according to the time when each matching device and the accessory device establish the first information channel, and sorting in order from near to far. In other embodiments, the first preset rule may be set to be sorted according to the time when each matching device has been set as the default device, in order from near to far, and the matching device that has not been set as the default device is sorted according to The time for establishing the first information channel between each matching device and the accessory device is sorted in order from near to far, so as to determine the polling sequence of each matching device.

S2809. The accessory device sends the first consultation information to the default device, and then executes S2810.

When the target device number is the device number of the default device, and there are multiple matching devices, the accessory device can send the first consultation information to the default device, and the default device is preferentially consulted.

Then, execute S2810, and determine whether the default device is the target device according to the information returned by the default device.

S2810. The accessory device determines whether the pairing failure information returned by the default device is received, and if yes, executes S2808, and if not, executes S2805.

When the electronic equipment receives the first point notification signal, if it has not received other point notification signals, that is, the second point notification signal, within the second preset time period before receiving the first point notification signal, the electronic device can The reception of the first point-reporting signal is determined as the first-time point-receiving point, and the second time when the point-receiving point is received for the first time is recorded.

After receiving the first consultation information, the default device can inquire whether the last received signal is the first to receive the report.

If the last time the default device receives an announcement signal is the first time an announcement is received, the default device may calculate a deviation value between the second time and the first time in the first consultation information.

If the above deviation value is less than the preset deviation threshold, the default device may return pairing confirmation information to the accessory device.

If the last time the default device receives an announcement signal is not the first time to receive an announcement, the default device does not record the second time, or the above deviation value is greater than or equal to the preset deviation threshold, the default device can return pairing failure information to the accessory device.

Therefore, after sending the first consultation information, the accessory device can determine whether to receive the pairing failure information sent by the default device.

If the accessory device receives the pairing failure information sent by the default device, it means that the target device is not the default device. At this time, the accessory device executes S2808 to poll each matching device to identify the target device.

If the accessory device receives the pairing confirmation information sent by the default device, it means that the target device is the default device. At this time, the accessory device does not need to switch the default device, and S2805 is executed.

S2811. The accessory device determines whether the pairing confirmation information returned by the matching device is received, and if so, executes S2813, and if not, executes S2812.

After determining the polling sequence of each matching device, the accessory device may send the first consultation information to each matching device in sequence according to the polling sequence.

After each time the accessory device sends the first consultation information to the matching device, it may determine whether to receive the pairing confirmation information returned by the matching device. The pairing confirmation message carries a confirmation indication.

If the accessory device receives the pairing confirmation information returned by the matching device, the accessory device executes S2813.

If the accessory device receives the pairing failure information returned by the matching device, the accessory device executes S2812.

S2812, the accessory device determines whether all matching devices have been polled, if so, execute S2814, and if not, execute S2808.

After receiving the pairing failure information returned by the matching device, the accessory device can query whether all matching devices have been polled.

If the accessory device has not polled all matching devices, the accessory device may return to S2808, switch to the next matching device according to the polling sequence, send the first consultation information to the next matching device, and continue to perform the query operation.

If the accessory device has polled all matching devices, it means that the target device is not in the verification device, and at this time, the accessory device may execute S2814 to perform a preset prompt operation.

S2813, the accessory device sets the electronic device that sends the pairing confirmation information as a new default device.

If the accessory device receives the pairing confirmation message, it means that the sender of the pairing confirmation message is the target device, the accessory device can be paired with the electronic device that sent the pairing confirmation message, and the pairing of the electronic device that sends the pairing confirmation message is set as the new default device .

S2814, the accessory device performs a preset prompt operation.

The accessory device can perform a preset prompt operation to remind the user to turn on the wireless communication function of the target device.

S2902. The electronic device determines whether the second point notification signal has not been received within the second preset time period before receiving the first point notification signal, and if so, executes S2905, and if not, executes S2903.

After receiving the first point notification signal, the electronic device may determine whether other point notification signals, that is, the second point notification signal, have been received within the second preset time period before receiving the first point notification signal.

If the electronic device has detected the second point notification signal within the second preset time period before detecting the first point notification signal, the electronic device determines that the current reception of the first point notification signal is not the first notification point received. At this time, the electronic device executes S2903.

If the electronic equipment has not detected the second point notification signal within the second preset time period before detecting the first point notification signal, the electronic device determines that the first point notification signal received this time is the first notification point received, and executes S2905 .

S2903. The electronic device receives the first consultation information carrying the first time, and then executes S2904.

When the electronic device receives the report signal for the first time and it is not the first time to receive the report, if it is queried by the accessory device and receives the first consultation information carrying the first time, it means that the accessory device that sent the first consultation information It is not the accessory device currently in contact with the electronic device (hereinafter referred to as the contact device), and at this time, the electronic device executes S2904.

S2904, the electronic device sends the pairing failure information to the sender of the first consultation information.

When the electronic device is inquired by an accessory device other than the contact device, the electronic device may send pairing failure information to the sender of the first inquiry message, so as to inform the accessory device that the inquiring object is wrong.

S2905, the electronic device records the second time, and then executes S2906.

When the electronic device determines that the reception of the first alarm signal is the first time to receive the alarm, the electronic device may record the second time when the first alarm signal is received, so as to perform the verification operation subsequently.

S2906, the electronic device receives the first consultation information carrying the first time, and then executes S2907.
