Detailed Description

Embodiments of the present application are described below with reference to the accompanying drawings.

The Bluetooth pairing method provided by the embodiment of the application is suitable for the pairing process between devices in Bluetooth communication. First, a pairing process will be described.

In bluetooth communication, a pairing process needs to be performed first before two devices perform bluetooth communication for the first time. After the two devices are paired, information such as a bluetooth address (bluetooth device address, bd_addr), a key, and the like is stored in the devices, so that bluetooth communication is possible. Subsequently, if the information such as the bluetooth address and the key stored in the two devices is not emptied, when the bluetooth communication is performed again, a bluetooth connection request can be sent between the two devices according to the bluetooth address, and the pairing process is not required to be performed again.

By way of example, fig. 1 is a schematic diagram of a scenario of bluetooth communication. As shown in fig. 1, both the electronic device 100 and the bluetooth device 200 support bluetooth functions, and the electronic device 100 and the bluetooth device 200 can perform bluetooth communication.

The types and names of the electronic device 100 and the bluetooth device 200 are not limited. Examples of some electronic devices are, for example: a wireless terminal in a cell phone, tablet, notebook, palm, wearable device, smart screen, teaching device, internet of things (internet of things, IOT) device, or smart home (smart home), etc. Optionally, the electronic device 100 has a display screen. Examples of some bluetooth devices are: bluetooth headset, bluetooth sound box, bluetooth handwriting pen, etc.

For convenience of explanation, the embodiment of the present application will be described taking the electronic device 100 as a mobile phone and the bluetooth device 200 as a bluetooth headset as an example.

Next, a message flow in the pairing process will be described. To facilitate understanding, the pairing process may include a discovery device phase and a pairing phase. In the discovery device phase, the electronic device can discover the paired bluetooth device, and interact with the bluetooth device with relevant information required in the pairing phase, such as the bluetooth address of the bluetooth device. In the pairing phase, the electronic device and the Bluetooth device can exchange information such as keys for subsequent Bluetooth communication.

Fig. 2 is a message interaction diagram of the bluetooth device and the electronic device in fig. 1 during pairing. As shown in fig. 2, the pairing process between devices in bluetooth communication may include:

s21, the Bluetooth device responds to the operation of the user on the Bluetooth device and enters a pairing mode.

Specifically, the user needs to operate the bluetooth device so that the bluetooth device enters a pairing mode. When the bluetooth device is in the pairing mode, the electronic device may search for a query request (query request) sent by the electronic device, and reply a query response (query response) to the electronic device, so that the electronic device discovers the bluetooth device. When the use states of the bluetooth devices are different, the operations of the users on the bluetooth devices can be different.

Optionally, in one implementation, the first case of using the bluetooth headset is opened. As shown on the left side of fig. 3A, the bluetooth headset includes a cover 201 and a case 202. The Bluetooth headset is never used after leaving the factory. As shown on the right side of fig. 3A, when the bluetooth headset is first opened for use, the bluetooth headset may be triggered to enter the pairing mode. Correspondingly, the Bluetooth headset enters a pairing mode in response to the operation of a user.

Alternatively, in another implementation, a scenario in which the bluetooth headset is not first used is provided. As shown on the left side of fig. 3B, the bluetooth headset has been used to communicate bluetooth with at least one electronic device. As shown on the right side of fig. 3B, when the bluetooth headset needs to perform bluetooth communication with an unpaired electronic device, or when bluetooth communication with an electronic device that has been historically paired but needs to be paired again, the user may press the physical key 203 on the box 202, triggering the bluetooth headset to enter the pairing mode. Accordingly, the bluetooth headset enters a pairing mode in response to an operation of the user pressing the physical key 203.

It should be noted that, in the embodiment of the present application, the name of the pairing mode is not limited. For example, the pairing mode may also be referred to as a pairing state or a query scan (query scan) state.

S22, the electronic equipment sends a query request (query request). Correspondingly, bluetooth devices in a pairing mode around the electronic device can scan the inquiry request and receive the inquiry request.

Specifically, after the electronic device turns on the bluetooth function, the electronic device may enter an inquiry (inquiry) state, and send an inquiry request to surrounding devices. Accordingly, if the surrounding bluetooth devices are in the pairing mode, the inquiry request may be scanned, and an inquiry response (query response) may be replied to the electronic device, so that the electronic device may discover the bluetooth device.

The execution order of S21 and S22 is not limited. For example, the user triggers the bluetooth headset to enter the pairing mode by pressing a physical key on the bluetooth headset box, and then the electronic device turns on the bluetooth function, i.e., performs S21 first and then S22. For another example, the electronic device turns on the bluetooth function first, and then the user first opens the box to trigger the bluetooth headset to enter the pairing mode using the bluetooth headset, that is, S22 is executed first and S21 is executed second.

The inquiry request includes a bluetooth address of the electronic device, and the bluetooth address may refer to related content in a bluetooth protocol, which is not described herein.

Alternatively, the electronic device may send the query request according to the first period. Alternatively, the bluetooth device in pairing mode may scan for inquiry requests according to the second period. Alternatively, the first period and the second period may be the same or different.

S23, the Bluetooth device sends a query response (query response) to the electronic device. Correspondingly, the electronic equipment receives the inquiry response sent by the Bluetooth equipment.

The inquiry response comprises the Bluetooth address of the Bluetooth device.

Specifically, after the bluetooth device in the pairing mode scans the inquiry request sent by the electronic device, an inquiry response can be returned to the electronic device according to the bluetooth address of the electronic device in the inquiry request, so that the electronic device can find the bluetooth device and continue to perform a subsequent pairing process with the electronic device.

The discovery device stage includes, but is not limited to, S21 to S23. For example, in the discovery device phase, the electronic device and the bluetooth device may also obtain at least one of the following information through interaction of messages: device name of the bluetooth device, device support characteristics (device supported feature) information of the electronic device, device support characteristics information of the bluetooth device. The device supporting feature information may also be referred to as capability information, and reference may be made to content related to a device feature (device feature) in the bluetooth protocol, which is not described herein.

By the discovery device phase, the electronic device can discover nearby paired bluetooth devices. By way of example, fig. 4A shows a schematic interface diagram of an electronic device at the discovery device stage. As shown in fig. 4A, the bluetooth main interface 40 of the mobile phone includes a bluetooth-enabled switch control 41, an open-detected switch control 42, a "device name" tab 43, a "received file" tab 44, paired devices 45, and available devices 46. The name of the handset is "handset 2" as known from the "device name" tab 43. The paired device 45 shows the device that the handset 2 historically successfully paired, e.g., handset 1. The available device 46 displays the currently paired devices found by the handset 2, for example a bluetooth headset. As shown in fig. 4A, the user may click on the bluetooth headset in the available device 46 to pair the handset 2 with the bluetooth headset. Correspondingly, the mobile phone 2 starts a pairing phase in the pairing process in response to the operation of the user.

Optionally, before pairing with the bluetooth headset, the mobile phone 2 may also display a prompt message. Illustratively, after the user clicks on the Bluetooth headset in the available device 46 in FIG. 4A, a variation of the Bluetooth master interface 40 may be seen in FIG. 4B. As shown in fig. 4B, the handset 2 pops out the pairing popup window 47 in the bluetooth main interface 40. The user operates by looking at the prompt in the pairing pop-up 47. For example, the hint information includes: "to pair with: bluetooth earphone. Also included in pairing pop-up window 47 are a cancel key and a pairing key. The user may click on the pairing button 48 to cause the handset 2 to pair with the bluetooth headset. Accordingly, the mobile phone 2 executes the message flow of the pairing phase in response to the operation of clicking the pairing key 48 by the user, specifically see S24.

And S24, the electronic equipment sends a pairing request to the Bluetooth equipment. Correspondingly, the Bluetooth device receives a pairing request sent by the electronic device.

And S25, the Bluetooth device sends a pairing response (pairing response) to the electronic device. Correspondingly, the electronic equipment receives the pairing response sent by the Bluetooth equipment.

Specifically, in the pairing stage, the electronic device may send a pairing request to the bluetooth device according to the bluetooth address of the bluetooth device, and the bluetooth device may send a pairing response to the electronic device according to the bluetooth address of the electronic device, where the pairing request and the pairing response are used to exchange configuration information, and the configuration information is used to determine a pairing mode and assign a key.

Alternatively, the configuration information may include input-output capabilities of the electronic device. Different electronic devices are different in type, different in hardware configuration and different in input and output capabilities. For example, the input-output capability may indicate at least one of: whether the electronic device can input, the input mode when the electronic device can input, whether the electronic device can display, and the like. Alternatively, the input-output capabilities of the electronic device may include any one of the following: no input and no output, only display, with display and selectable "yes/no", only keyboard, with keyboard and display.

The pairing stage includes, but is not limited to, S24 to S25. For example, in the pairing phase, it is also necessary to determine a pairing algorithm of the electronic device and the bluetooth device, establish an encryption link, and transmit a key, which can be referred to as content of pairing authentication in the bluetooth protocol, which is not described herein.

After the electronic equipment and the Bluetooth equipment are paired, information such as a secret key is stored in the equipment, and Bluetooth communication can be carried out between the electronic equipment and the Bluetooth equipment subsequently. By way of example, fig. 4C shows a schematic diagram of an interface of an electronic device after pairing of the electronic device and a bluetooth device is completed. In contrast to fig. 4A, as shown in fig. 4C, in the bluetooth main interface 40, the paired device 45 includes the handset 1 and the bluetooth headset, which indicates that the handset 2 and the bluetooth headset have completed pairing, and bluetooth communication can be performed subsequently.

The embodiment of the application does not limit the type of the service. Such as telephony services and audio services. Optionally, the call service includes, but is not limited to: voice call or video call; audio services include, but are not limited to: play music, alert tones, navigation tones, alarm clocks, games, video, etc.

Through the message flow of the pairing process shown in fig. 2, it can be known that when the bluetooth device is paired with the electronic device, the bluetooth device needs to be in a pairing mode, so that the bluetooth device can scan the inquiry request sent by the electronic device and reply to the inquiry response. Correspondingly, the electronic device discovers the Bluetooth device which can be paired, acquires the Bluetooth address of the Bluetooth device from the inquiry response sent by the Bluetooth device, and can send a pairing request to the Bluetooth device according to the Bluetooth address of the Bluetooth device subsequently to continue the pairing process.

Currently, controlling a bluetooth headset to enter a pairing mode requires a user to operate the bluetooth headset. When the Bluetooth device is used for the first time, a user opens the box to trigger the Bluetooth headset to enter a pairing mode. The bluetooth headset is used for the first time only once, and in most application scenes, the bluetooth equipment is in a used state, and at the moment, a user needs to manually operate a physical key on the bluetooth headset box to enable the bluetooth headset to enter a pairing mode. However, many users are not aware of this operation, so that the bluetooth headset which is not used for the first time cannot enter a pairing mode, and cannot complete the pairing process with the electronic device, so that subsequent bluetooth communication and service cannot be performed, and the use feeling of the user on the bluetooth headset is seriously affected.

The embodiment of the application provides a Bluetooth pairing method, by means of a third party device except electronic equipment and Bluetooth equipment, the Bluetooth equipment can be controlled to enter a pairing mode through the third party device, so that the situation that a user can trigger the Bluetooth equipment to enter the pairing mode after operating the Bluetooth equipment is avoided, and inconvenience of operating the Bluetooth equipment by the user is eliminated. Moreover, the electronic equipment can obtain the Bluetooth address of the Bluetooth equipment without sending a query request to the Bluetooth equipment, so that the message flow of the pairing process is simplified, the realizability and convenience of the pairing process of the Bluetooth equipment which is not used for the first time and the electronic equipment which is not paired are improved, and the use experience of a user is improved.

For convenience of explanation, an electronic device that needs to be paired with a bluetooth device is referred to as a first electronic device, a third party device other than the first electronic device and the bluetooth device is referred to as a second electronic device, and the bluetooth device is historically paired with the second electronic device successfully without clearing data.

Fig. 6 is a message interaction diagram of a bluetooth pairing method according to an embodiment of the present application. The bluetooth pairing method provided by the embodiment is suitable for the scene shown in fig. 5, and the execution subject relates to bluetooth equipment, first electronic equipment and second electronic equipment. Optionally, the execution body may also relate to a third electronic device. For ease of illustration, in some examples, the bluetooth device is a bluetooth headset, the first electronic device is a cell phone 1, the second electronic device is a cell phone 2, and the third electronic device is a display 3. As shown in fig. 6, the bluetooth pairing method provided in this embodiment may include:

s61, the Bluetooth device establishes Bluetooth connection with the second electronic device.

Alternatively, the bluetooth connection may comprise an asynchronous connection (asynchronous connection-oriented, ACL) connection. The ACL connection is a connection on the physical layer in the bluetooth protocol, and may refer to the relevant content in the bluetooth protocol, which is not described herein.

Optionally, the bluetooth connection may further comprise at least one of the following: a synchronous oriented link (SCO) connection, an advanced audio distribution profile (advanced audio distribution profile, A2 DP) connection, or a Hands Free Profile (HFP) connection. The SCO connection is a connection on a physical layer in the bluetooth protocol, and the A2DP connection and the HFP connection are connections on an application layer in the bluetooth protocol, which may refer to related contents in the bluetooth protocol, and are not described herein.

In this embodiment, the time for establishing bluetooth connection between the bluetooth device and the second electronic device in the application scenario is not limited.

Optionally, in an application scenario, the bluetooth device does not currently establish a bluetooth connection with the second electronic device. When the Bluetooth device needs to be paired with the first electronic device, the Bluetooth device establishes a Bluetooth connection with the second electronic device. For example, the handset 2 does not currently have bluetooth functionality on. When the Bluetooth headset needs to be paired with the mobile phone 1, the user opens the Bluetooth function of the mobile phone 2, and the mobile phone 2 can automatically establish Bluetooth connection with the Bluetooth headset.

Optionally, in another application scenario, when the bluetooth device needs to be paired with the first electronic device, the bluetooth device has already established a bluetooth connection with the second electronic device. For example, the user is listening to music played on the handset 2 via a bluetooth headset, which also needs to be paired with the handset 1.

And S62, the second electronic device sends notification information to the Bluetooth device, wherein the notification information is used for indicating the Bluetooth device to enter a pairing mode. Correspondingly, the Bluetooth device receives the notification information sent by the second electronic device.

The second electronic device sends notification information to the Bluetooth device to indicate the Bluetooth device to enter the pairing mode, so that the situation that a user must operate the Bluetooth device to enable the Bluetooth device to enter the pairing mode is avoided, inconvenience in operation of the Bluetooth device by the user is avoided, and feeling of using the Bluetooth device by the user is improved.

Alternatively, in one implementation, after the bluetooth device establishes a bluetooth connection with the second electronic device, the second electronic device may be triggered to send notification information to the bluetooth device. For example, a user may wish to pair a bluetooth headset with a handset 1, where the bluetooth headset and handset 1 are located, the user typically knows a second electronic device in the environment, e.g., handset 2. For example, the mobile phone 1 and the mobile phone 2 are mobile phones used by the user 1; alternatively, user 1 uses mobile phone 1, and user 1 knows that user 2 uses mobile phone 2. Like this, when user 1 need pair bluetooth headset with cell-phone 1, can open the bluetooth function of cell-phone 2, cell-phone 2 establishes bluetooth with bluetooth headset and is connected to trigger cell-phone 2 to send the notice information to bluetooth headset, instruct bluetooth headset to get into the mode of pairing.

Alternatively, in another implementation manner, the first operation may be performed on the second electronic device by the user, so as to trigger the second electronic device to send notification information to the bluetooth device.

The first operation of the second electronic device is not limited by the user in this embodiment. For example, the first operation by the user may be any one of the following: the method comprises the steps of performing touch operation on a related interface displayed by the second electronic device by a user, performing gesture operation on a display screen of the second electronic device by the user, performing operation on physical keys on the second electronic device by the user, inputting voice by a microphone of the second electronic device by the user, or inputting an image by a camera of the second electronic device by the user. Optionally, the second electronic device may be provided with an Application (APP) for managing the bluetooth device, and in this embodiment, the name and function of the APP are not limited, and the content and layout in the relevant interface of the APP are not limited.

The following is illustrated by way of example.

Alternatively, in one example, as shown in fig. 7A, the handset 2 is currently running a system application, displaying a bluetooth host interface 70 in the system application. It is known from the paired device 71 in the bluetooth main interface 70 that the bluetooth connection is currently made between the handset 2 and both the handset 1 and the bluetooth headset. The user may click on the bluetooth headset in the paired device 71, triggering the handset 2 to send notification information to the bluetooth headset. Accordingly, the mobile phone 2 transmits notification information to the bluetooth headset in response to the user's operation.

Optionally, the bluetooth main interface 70 includes prompt information for guiding the user to perform the first operation. For example, in fig. 7A, there is a prompt "click on bluetooth headset to enter pairing mode" below bluetooth headset.

Optionally, before the second electronic device sends the notification information to the bluetooth device, a prompt message may be displayed to the user. Illustratively, as shown in fig. 7A, the user clicks on the bluetooth headset in the paired device 71, triggering the handset 2 to send notification information to the bluetooth headset. Accordingly, as shown in fig. 7B, the cellular phone 2 pops up the pop-up window 72 in the bluetooth main interface 70 in response to the user's operation. The user operates by viewing the prompt in the pop-up window 72. For example, the hint information includes: "bluetooth headset enters pairing mode". Also included in the pop-up window 72 are a cancel button and a ok button. The user may click the ok button 73 triggering the handset 2 to send a notification message to the bluetooth headset. Accordingly, in response to the user clicking the ok button 73, the mobile phone 2 transmits notification information to the bluetooth headset, instructing the bluetooth headset to enter the pairing mode.

Alternatively, in another example, fig. 8A shows another interface diagram of the handset 2. Fig. 8A and 7A differ in that: in fig. 7A, the handset 2 runs a system application, displaying a bluetooth host interface 70 in the system application; in fig. 8A, the handset 2 runs a third party application for managing other devices in communication with the handset 2. The name, function and interface layout of the third party application are not limited in the embodiments of the present application. For example, as shown in fig. 8A, the handset 2 currently displays a "my devices" interface 80 in a third party application, and the devices that communicate with the handset 2 include: door lock 001, bluetooth headset, gateway 1 and cell-phone 1 in the house. The right side of the bluetooth headset in the interface 80 has a button 85. The user may click on button 85 triggering the handset 2 to send a notification message to the bluetooth headset. Accordingly, the cellular phone 2 ejects the pop-up window 81 in the interface 80 in response to the user's operation, see fig. 8B. The popup window 81 can be referred to as popup window 72 in fig. 7B, and the principle is similar, and will not be described herein. Optionally, the interface 80 includes prompt information for guiding the user to perform the first operation. For example, in fig. 8A, a prompt "click right button" is provided below the bluetooth headset, and the bluetooth headset enters the pairing mode.

Fig. 7A to 7B and fig. 8A to 8B are only examples, and are not limited to the relevant interface and the first operation of the user. For example, in fig. 7A or fig. 8A, the setting interface of the bluetooth headset may be accessed through a related operation of the user, and by performing a first operation in the setting interface, the mobile phone 2 is triggered to send notification information to the bluetooth headset.

Optionally, the notification information may be carried in an interaction message defined in the bluetooth protocol, or may be carried in a private message defined between the second electronic device and the bluetooth device, where the name of the message and the carrying manner of the notification information in the message are not limited in this embodiment.

Alternatively, the second electronic device may send the notification information through an Echo (Echo or Echo) channel of the logical link control and adaptation protocol (logical link control and adaptation layer protocol, L2 CAP). The ECHO protocol may refer to the CORE Host section of the bluetooth protocol, e.g., section PartA 4.8.

S91, the second electronic device sends an l2cap_echo_req (logical link control and adaptation protocol ECHO request) message to the bluetooth device, where the l2cap_echo_req message includes notification information. Accordingly, the bluetooth device receives the l2cap_echo_req message transmitted by the second electronic device.

S92, the bluetooth device sends an l2cap_echo_rsp (logical link control and adaptation protocol ECHO response) message to the second electronic device, where the l2cap_echo_rsp message is used to indicate that the bluetooth device receives the l2cap_echo_req message.

Specifically, in the ECHO protocol, an ECHO request (ECHO request or echo_req or l2cap_echo_req) is typically used to request a response from a remote L2CAP entity, which may be used to test a link or to transmit specific information using an optional data field. After receiving the valid ECHO request packet, the L2CAP entity replies with an ECHO response (ECHO response or echo_rsp or l2cap_echo_rsp) packet. In the present embodiment, the specific information is notification information.

Fig. 10A is a schematic diagram of a format of a data packet corresponding to an l2cap_echo_req message provided in an embodiment of the present application, and fig. 10B is a schematic diagram of a format of a data packet corresponding to an l2cap_echo_rsp message provided in an embodiment of the present application. As shown in fig. 10A, the data Packet (Packet) corresponding to the l2cap_echo_req message has the least significant bit (least significant bit, LSB) on the left and the most significant bit (most significant bit, MSB) on the right, and includes: a Code field, an Identifier field, a Length field, and a Data field. Wherein the data field is an optional field. The packet provided by the ECHO protocol may carry custom information in optional data fields. In this embodiment, notification information may be carried in the data field. The format of the data packet corresponding to the l2cap_echo_rsp message shown in fig. 10B is similar to the format of the data packet corresponding to the l2cap_echo_req message shown in fig. 10A, wherein the identifier fields in the l2cap_echo_rsp message and the l2cap_echo_req message match, and the encoding fields match. For example, the identifier field in fig. 10A and 10B has the same value. For example, the code field in fig. 10A has a value of 0x08, and the code field in fig. 10B has a value of 0x09.

Next, based on the embodiment shown in fig. 6, a specific embodiment in which the first electronic device acquires pairing information from the second electronic device or the bluetooth device or the third electronic device in S64 is provided. For convenience of explanation, pairing information is taken as an example including bluetooth address and capability information of a bluetooth device.

Optionally, in one embodiment, in S64, the first electronic device obtains the pairing information by scanning the pairing information displayed by the second electronic device in a visual form. For convenience of explanation, the pairing information in a visual form is two-dimensional code information. As shown in fig. 11, in S64, the first electronic device obtains pairing information from the second electronic device, which may include:

and S111, the second electronic device generates two-dimension code information according to the Bluetooth address and the capability information of the Bluetooth device.

Specifically, the second electronic device performs bluetooth communication with the bluetooth device, and bluetooth address and capability information of the bluetooth device are stored. The second electronic device may generate two-dimensional code information according to the bluetooth address and the capability information of the bluetooth device, so as to be provided to the first electronic device subsequently. The two-dimensional code information may be generated by using an existing algorithm, which is not described in detail in this embodiment.

Here, S111 is executed after S61, but the execution order between S111 and S62 to S63 is not limited.

Optionally, in the first implementation, S111 is performed before S62, and after the bluetooth device establishes a bluetooth connection with the second electronic device in S61, the second electronic device is triggered to perform S111. For example, the user uses handset 1 and handset 2, handset 2 successfully pairs with the bluetooth headset, and handset 1 never pairs with the bluetooth headset. Like this, when the user need pair bluetooth headset with cell-phone 1, can open the bluetooth function of cell-phone 2, cell-phone 2 establishes bluetooth with bluetooth headset and is connected, triggers cell-phone 2 and generates two-dimensional code information according to bluetooth headset's bluetooth address and ability information.

Optionally, in a second implementation, S111 is performed before S62, and the second electronic device is triggered to perform S111 by the user performing a second operation on the second electronic device.

Illustratively, as shown in fig. 7A, the handset 2 is currently running a system application, displaying a bluetooth host interface 70 in the system application. The bluetooth connection between the handset 2 and both the handset 1 and the bluetooth headset is known from the paired device 71 in the bluetooth main interface 70. The user may click on the bluetooth headset in the paired device 71, triggering the mobile phone 2 to generate two-dimensional code information according to the bluetooth address and capability information of the bluetooth headset. Correspondingly, the mobile phone 2 responds to the operation of the user to generate two-dimensional code information.

Optionally, the bluetooth main interface 70 includes prompt information for guiding the user to perform the second operation. For example, a prompt message "click on a bluetooth headset to share pairing information of the bluetooth headset" may be displayed.

Optionally, before the second electronic device generates the two-dimensional code information according to the bluetooth address and the capability information of the bluetooth device, prompt information may be displayed to the user.

Illustratively, in one example, as shown in FIG. 7A, the user clicks on a Bluetooth headset in the paired device 71. Accordingly, as shown in fig. 7C, the cellular phone 2 pops up the pop-up window 74 in the bluetooth main interface 70 in response to the user's operation. The user operates by viewing the prompt in the pop-up window 74. For example, the hint information includes: "pairing information of bluetooth headset is displayed". Also included in the pop-up window 74 are a cancel button and a ok button. The user can click the determining button to trigger the mobile phone 2 to generate two-dimension code information according to the Bluetooth address and the capability information of the Bluetooth headset. Correspondingly, the mobile phone 2 responds to the operation of clicking the determination key by the user, and generates two-dimension code information according to the Bluetooth address and the capability information of the Bluetooth headset.

Illustratively, in another example, as shown in FIG. 7A, the user clicks on a Bluetooth headset in the paired device 71. Accordingly, as shown in fig. 7D, the cellular phone 2 pops up a pop-up window 75 in the bluetooth main interface 70 in response to the user's operation. The user operates by viewing the prompt in the pop-up window 75. For example, the hint information includes: "share pairing information of bluetooth headset". The popup 75 includes various sharing manners of pairing information, such as displaying two-dimensional codes, bluetooth sharing, wiFi sharing, and network sharing. The bluetooth sharing means that pairing information is provided for the mobile phone 1 through bluetooth communication between the mobile phone 2 and the mobile phone 1, the WiFi sharing means that pairing information is provided for the mobile phone 1 through WiFi communication between the mobile phone 2 and the mobile phone 1, and the network sharing means that pairing information is provided for the mobile phone 1 through cellular communication between the mobile phone 2 and the mobile phone 1. The pop-up window 75 further includes a cancel button and a confirm button for canceling the sharing pairing information and confirming the sharing pairing information. The user can click on the selection control 76 for displaying the two-dimensional code mode to select the sharing mode of the two-dimensional code. As shown in fig. 7E, the display state of the selection control 76 changes, and the user continues to click the ok button, triggering the mobile phone 2 to generate two-dimensional code information according to the bluetooth address and capability information of the bluetooth headset. Correspondingly, the mobile phone 2 responds to the operation of the user and generates two-dimension code information according to the Bluetooth address and the capability information of the Bluetooth headset.

Alternatively, the second operation and the first operation may be the same operation. For example, as shown in fig. 7A, the user clicks the bluetooth headset in the paired device 71 in the bluetooth main interface 70, triggers the mobile phone 2 to generate two-dimensional code information according to the bluetooth address and capability information of the bluetooth headset, and at the same time triggers the mobile phone 2 to send notification information to the bluetooth headset. For another example, as shown in fig. 7B, the user clicks the ok button 73 in the pop window 72, and triggers the mobile phone 2 to send notification information to the bluetooth headset, and at the same time, triggers the mobile phone 2 to generate two-dimensional code information according to the bluetooth address and capability information of the bluetooth headset. For another example, as shown in fig. 7C, the user clicks the ok button in the pop window 74, triggers the mobile phone 2 to generate two-dimensional code information according to the bluetooth address and capability information of the bluetooth headset, and at the same time triggers the mobile phone 2 to send notification information to the bluetooth headset. For another example, as shown in fig. 7E, the user selects the control 76 in the pop-up window 75, clicks the ok button, triggers the mobile phone 2 to generate two-dimensional code information according to the bluetooth address and capability information of the bluetooth headset, and at the same time triggers the mobile phone 2 to send notification information to the bluetooth headset.

Optionally, in a third implementation, S111 is performed after S62, and after the second electronic device sends notification information to the bluetooth device in S62, the second electronic device is triggered to perform S111.

Optionally, in a fourth implementation, S111 is performed after S62, and the second electronic device is triggered to perform S111 by the user performing a second operation on the second electronic device.

Fig. 7A to 7E are only examples, and do not limit the second operation of the second electronic device by the user.

The user can click the mobile phone 1 to trigger the mobile phone 2 to establish communication connection with the mobile phone 1, so that the subsequent mobile phone 2 can send pairing information of the Bluetooth device to the mobile phone 1. Accordingly, the mobile phone 2 establishes a communication connection with the mobile phone 1 in response to the operation of the user. This scenario is applicable to users knowing pairing information that needs to share bluetooth headset with the handset 1.

Optionally, before the second electronic device establishes a communication connection with the first electronic device, a prompt message may be displayed to the user.

The implementation is applicable to a scenario in which only the first electronic device, the second electronic device and the Bluetooth device are present in the environment.

In the first implementation, optionally, S131 is performed after S62, and the second electronic device is triggered to perform S131 by the user performing a third operation on the second electronic device.
