Detailed Description

The technical scheme of the application will be described below with reference to the accompanying drawings.

Fig. 1 is a schematic view of a scenario in which an embodiment of the present application is applicable. As shown in fig. 1, a stylus (stylus) 100 and an electronic device 200 are included in the scene. An electronic device 200 is illustrated in fig. 1 as a tablet computer (tablet). The stylus 100 may provide input to the electronic device 200, and the electronic device 200 performs an operation responsive to the input based on the input of the stylus 100. In one embodiment, the stylus 100 and the electronic device 200 may be interconnected by a communication network to enable interaction of wireless signals. The communication network may be, but is not limited to: wireless fidelity (wireless fidelity, WI-FI) hotspot network, WI-FI point-to-point (P2P) network, bluetooth network, zigbee network, or near field communication (near field communication, NFC) network.

The stylus 100 may be, but is not limited to: inductive pens and capacitive pens. When the electronic device 200 has a touch screen 201 and the stylus 100 is an inductive pen, an electromagnetic induction board needs to be integrated on the touch screen 201 of the electronic device 200 that interacts with the stylus 100. The electromagnetic induction plate is provided with coils, and the induction pen is also integrated with the coils. Based on the electromagnetic induction principle, in the magnetic field range generated by the electromagnetic induction plate, along with the movement of the induction pen, the induction pen can accumulate electric energy. The inductive pen can transmit the accumulated electric energy to the electromagnetic induction plate through the coil in the inductive pen through free oscillation. The electromagnetic induction plate can scan the coil on the electromagnetic induction plate based on the electric energy from the induction pen, and calculate the position of the induction pen on the touch screen 201. The touch screen 201 in the electronic device 200 may also be referred to as a touch screen and the stylus 100 may also be referred to as a stylus.

The capacitive pen may include: passive capacitive pens and active capacitive pens. Passive capacitive pens may be referred to as passive capacitive pens and active capacitive pens may be referred to as active capacitive pens.

One or more electrodes may be provided in the active capacitive pen (e.g., within the pen tip), through which the active capacitive pen may emit a signal. When the stylus 100 is an active capacitive stylus, an integrated electrode array is required on the touch screen 201 of the electronic device 200 that interacts with the stylus 100. In one embodiment, the electrode array may be a capacitive electrode array. The electronic device 200 may receive a signal from the active capacitive pen through the electrode array, and further identify the position of the active capacitive pen on the touch screen and the tilt angle of the active capacitive pen based on the change of the capacitance value on the touch screen 201 when the signal is received.

Fig. 2 is a schematic structural diagram of a stylus according to an embodiment of the present application. As shown in fig. 2, the stylus 100 may include a nib 10, a barrel 20, and a rear cover 30. The inside of the pen holder 20 is a hollow structure, the pen point 10 and the rear cover 30 are respectively positioned at two ends of the pen holder 20, the rear cover 30 and the pen holder 20 can be inserted or clamped, and the matching relationship between the pen point 10 and the pen holder 20 is detailed in the description of fig. 3.

Fig. 3 is a schematic diagram of a partially disassembled structure of a stylus according to an embodiment of the present application. As shown in fig. 3, the stylus 100 further includes a spindle assembly 50, the spindle assembly 50 is located in the pen holder 20, and the spindle assembly 50 is slidably disposed in the pen holder 20. Spindle assembly 50 has external threads 51 thereon and nib 10 includes writing end 11 and connecting end 12, wherein connecting end 12 of nib 10 has internal threads (not shown) that mate with external threads 51.

When the spindle assembly 50 is assembled into the barrel 20, the connecting end 12 of the nib 10 extends into the barrel 20 and is threadedly coupled with the external threads 51 of the spindle assembly 50. In some other examples, the connection between the connection end 12 of the pen tip 10 and the spindle assembly 50 may also be achieved by a removable manner, such as a snap fit. The replacement of the nib 10 is achieved by the removable connection between the connecting end 12 of the nib 10 and the spindle assembly 50.

In order to detect the pressure applied to the writing end 11 of the nib 10, as shown in fig. 2, a gap 10a is provided between the nib 10 and the barrel 20, so that when the writing end 11 of the nib 10 is subjected to an external force, the nib 10 can move towards the barrel 20, and the movement of the nib 10 drives the spindle assembly 50 to move in the barrel 20. In the detection of the external force, referring to fig. 3, a pressure sensing assembly 60 is provided on the spindle assembly 50, and a portion of the pressure sensing assembly 60 is fixedly connected with a fixing structure in the pen holder 20, and a portion of the pressure sensing assembly 60 is fixedly connected with the spindle assembly 50. Thus, when the spindle assembly 50 moves along with the pen tip 10, since a portion of the pressure sensing assembly 60 is fixedly connected with the fixing structure in the pen holder 20, the movement of the spindle assembly 50 drives the pressure sensing assembly 60 to deform, the deformation of the pressure sensing assembly 60 is transmitted to the circuit board 70 (for example, the pressure sensing assembly 60 and the circuit board 70 can be electrically connected through a wire or a flexible circuit board), and the circuit board 70 detects the pressure of the writing end 11 of the pen tip 10 according to the deformation of the pressure sensing assembly 60, so that the thickness of the line of the writing end 11 is controlled according to the pressure of the writing end 11 of the pen tip 10.

Note that the pressure detection of the pen tip 10 includes, but is not limited to, the above method. For example, the pressure of the pen tip 10 may be detected by a pressure sensor provided in the writing end 11 of the pen tip 10.

In this embodiment, as shown in fig. 3, the stylus pen 100 further includes a plurality of electrodes, which may be, for example, a first transmitting electrode 41, a ground electrode 43, and a second transmitting electrode 42. The first emitter electrode 41, the ground electrode 43, and the second emitter electrode 42 are all electrically connected to the circuit board 70. The first transmitting electrode 41 may be located in the pen tip 10 and close to the writing end 11, and the circuit board 70 may be configured as a control board that may provide signals to the first transmitting electrode 41 and the second transmitting electrode 42, respectively, the first transmitting electrode 41 being configured to transmit a first signal, and when the first transmitting electrode 41 is close to the touch screen 201 of the electronic device 200, a coupling capacitance may be formed between the first transmitting electrode 41 and the touch screen 201 of the electronic device 200, so that the electronic device 200 may receive the first signal. The second transmitting electrode 42 is configured to transmit a second signal, and the electronic device 200 may determine the tilt angle of the stylus 100 according to the received second signal. In an embodiment of the present application, the second emitter electrode 42 may be located on the inner wall of the barrel 20. In one example, the second emitter electrode 42 may also be located on the spindle assembly 50.

The ground electrode 43 may be located between the first and second transmitting electrodes 41 and 42, or the ground electrode 43 may be located at the outer circumference of the first and second transmitting electrodes 41 and 42, the ground electrode 43 serving to reduce coupling of the first and second transmitting electrodes 41 and 42 with each other.

When the electronic device 200 receives the first signal from the stylus 100, the capacitance value at the corresponding position of the touch screen 201 changes. Accordingly, the electronic device 200 may determine the location of the stylus 100 (or the tip of the stylus 100) on the touch screen 201 based on the change in capacitance value on the touch screen 201. In addition, the electronic device 200 may acquire the tilt angle of the stylus 100 using a dual-nib projection method in the tilt angle detection algorithm. The positions of the first transmitting electrode 41 and the second transmitting electrode 42 in the stylus 100 are different, so when the electronic device 200 receives the first signal and the second signal from the stylus 100, the capacitance values at two positions on the touch screen 201 will change. The electronic device 200 may obtain the tilt angle of the stylus 100 according to the distance between the first emitter electrode 41 and the second emitter electrode 42 and the distance between the two positions where the capacitance value changes on the touch screen 201, and more detailed obtaining of the tilt angle of the stylus 100 may be described with reference to the related art dual-nib projection method.

In this embodiment, as shown in fig. 3, the stylus 100 further includes: and a battery assembly 80, the battery assembly 80 being configured to provide power to the circuit board 70. The battery assembly 80 may include a lithium ion battery, or the battery assembly 80 may include a nickel-chromium battery, an alkaline battery, a nickel-hydrogen battery, or the like. In one embodiment, the battery included in the battery assembly 80 may be a rechargeable battery or a disposable battery, wherein when the battery included in the battery assembly 80 is a rechargeable battery, the stylus 100 may charge the battery in the battery assembly 80 by wireless charging.

When the stylus 100 is an active capacitive stylus, referring to fig. 4, after the electronic device 200 is wirelessly connected to the stylus 100, the electronic device 200 may send an uplink signal to the stylus 100 through an electrode array integrated on the touch screen 201. The stylus 100 may receive the uplink signal through the receiving electrode, and the stylus 100 transmits the downlink signal through the transmitting electrode (e.g., the first transmitting electrode 41 and the second transmitting electrode 42). The downstream signal includes the first signal and the second signal described above. When the tip 10 of the stylus 100 contacts the touch screen 201, the capacitance value at the corresponding position of the touch screen 201 changes, and the electronic device 200 may determine the position of the tip 10 of the stylus 100 on the touch screen 201 based on the capacitance value on the touch screen 201. In one embodiment, the upstream and downstream signals may be square wave signals.

The sensor layer can operate in a variety of modes. If operating in mutual capacitance mode, the column and row traces form a single capacitive sense node at each overlap point (e.g., a "vertical" mutual capacitance). If operating in self-capacitance mode, the column and row traces form two (vertically aligned) capacitive sense nodes at each overlap point. In another embodiment, if operating in a mutual capacitance mode, adjacent column traces and/or adjacent row traces may each form a single capacitive sense node (e.g., a "horizontal" mutual capacitance). As described above, the sensor layer may detect the presence of the tip 10 of the stylus 100 and/or the touch of a user's finger by monitoring the capacitance (e.g., mutual capacitance or self capacitance) change presented at each capacitive sensing node. In many cases, coordination engine 230 may be configured to detect tip and ring signals received from stylus 100 through the sensor layer via capacitive coupling.

Wherein the tip signal and/or the ring signal may include specific information and/or data that may be configured to cause the electronic device 200 to identify the stylus 100. Such information is generally referred to herein as "stylus identity" information. This information and/or data may be received by the sensor layer and interpreted, decoded, and/or demodulated by coordination engine 230.

Processor 210 may use the stylus identity information to simultaneously receive input from more than one stylus. In particular, coordination engine 230 may be configured to communicate to processor 210 the position and/or angular position of each of the number of styluses detected by coordination engine 230. In other cases, coordination engine 230 may also transmit information to processor 210 regarding the relative positions and/or relative angular positions of the plurality of styluses detected by coordination engine 230. For example, coordination engine 230 may notify processor 210 that the detected first stylus is located away from the detected second stylus.

In other cases, the end signal and/or ring signal may also include specific information and/or data for causing the electronic device 200 to identify a specific user. Such information is generally referred to herein as "user identity" information.

Coordination engine 230 may forward user identity information (if detected and/or recoverable) to processor 210. If the user identity information cannot be recovered from the tip signal and/or the ring signal, coordination engine 230 may optionally indicate to processor 210 that the user identity information is not available. Processor 210 can utilize user identity information (or the absence of such information) in any suitable manner, including but not limited to: accepting or rejecting input from a particular user, allowing or rejecting access to a particular function of the electronic device, etc. Processor 210 may use the user identity information to simultaneously receive input from more than one user.

In still other cases, the tip signal and/or the ring signal may include specific information and/or data that may be configured to cause the electronic device 200 to identify settings or preferences of the user or the stylus 100. Such information is generally referred to herein as "stylus setup" information.

Coordination engine 230 may forward the stylus setup information (if detected and/or recoverable) to processor 210. If the stylus setting information is not recoverable from the tip signal and/or the ring signal, coordination engine 230 may optionally indicate to processor 210 that the stylus setting information is not available. The electronic device 200 can utilize the stylus setting information (or the absence of the information) in any suitable manner, including but not limited to: applying settings to an electronic device, applying settings to a program running on an electronic device, changing line thickness, color, pattern presented by a graphics program of an electronic device, changing settings of a video game operating on an electronic device, and so forth.

In general, the processor 210 may be configured to perform, coordinate, and/or manage the functions of the electronic device 200. Such functions may include, but are not limited to: communication and/or transaction data with other subsystems of the electronic device 200, communication and/or transaction data with the stylus 100, data communication and/or transaction data over a wireless interface, data communication and/or transaction data over a wired interface, facilitating power exchange over a wireless (e.g., inductive, resonant, etc.) or wired interface, receiving a position and angular position of one or more styluses, etc.

Processor 210 may be implemented as any electronic device capable of processing, receiving, or transmitting data or instructions. For example, the processor may be a microprocessor, a central processing unit, an application specific integrated circuit, a field programmable gate array, a digital signal processor, an analog circuit, a digital circuit, or a combination of these devices. The processor may be a single-threaded or multi-threaded processor. The processor may be a single core or multi-core processor.

During use, processor 210 may be configured to access a memory storing instructions. The instructions may be configured to cause the processor to perform, coordinate, or monitor one or more operations or functions of the electronic device 200.

The instructions stored in the memory may be configured to control or coordinate the operation of other components of the electronic device 200, such as, but not limited to: another processor, analog or digital circuitry, a volatile or non-volatile memory module, a display, a speaker, a microphone, a rotational input device, buttons or other physical input devices, biometric sensors and/or systems, force or touch input/output components, a communication module (such as a wireless interface and/or power connector), and/or a haptic or tactile feedback device.

The memory may also store electronic data that may be used by the stylus or the processor. For example, the memory may store electronic data or content (such as media files, documents, and applications), device settings and preferences, timing signals and control signals, or data for various modules, data structures or databases, files or configurations related to detecting tip signals and/or ring signals, and so forth. The memory may be configured as any type of memory. For example, the memory may be implemented as random access memory, read only memory, flash memory, removable memory, other types of storage elements, or a combination of such devices.

The electronic device 200 also includes a power subsystem 240. The power subsystem 240 may include a battery or other power source. The power subsystem 240 may be configured to provide power to the electronic device 200. The power subsystem 240 may also be coupled to a power connector 250. The power connector 250 may be any suitable connector or port that may be configured to receive power from an external power source and/or to provide power to an external load. For example, in some embodiments, the power connector 250 may be used to recharge a battery within the power subsystem 240. In another embodiment, the power connector 250 may be used to transfer power stored (or available) within the power subsystem 240 to the stylus 100.

The electronic device 200 also includes a wireless interface 260 to facilitate electronic communications between the electronic device 200 and the stylus 100. In one embodiment, the electronic device 200 may be configured to communicate with the stylus 100 via a low energy bluetooth communication interface or a near field communication interface. In other examples, the communication interface facilitates electronic communications between the electronic device 200 and an external communication network, device, or platform.

The wireless interface 260 (whether the communication interface between the electronic device 200 and the stylus 100 or another communication interface) may be implemented as one or more wireless interfaces, bluetooth interfaces, near field communication interfaces, magnetic interfaces, universal serial bus interfaces, inductive interfaces, resonant interfaces, capacitively coupled interfaces, WI-FI interfaces, transmission control protocol/internet protocol (transmission control protocol/internet protocol, TCP/IP) interfaces, network communication interfaces, optical interfaces, acoustical interfaces, or any conventional communication interfaces.

The electronic device 200 also includes a display 270. The display 270 may be located behind the input surface 220 or may be integral therewith. A display 270 may be communicatively coupled to the processor 210. Processor 210 may present information to a user using display 270. In many cases, the processor 210 uses the display 270 to present an interface with which a user may interact. In many cases, the user manipulates the stylus 100 to interact with the interface.

It will be apparent to one skilled in the art that some of the specific details presented above with respect to the electronic device 200 may not be required to practice a particular described embodiment or equivalent thereof. Similarly, other electronic devices may include a greater number of subsystems, modules, components, etc. Some of the sub-modules may be implemented as software or hardware, where appropriate. It should be understood, therefore, that the foregoing description is not intended to be exhaustive or to limit the disclosure to the precise form described herein. On the contrary, many modifications and variations will be apparent to those of ordinary skill in the art in light of the above disclosure.

At present, when a stylus is connected with an electronic device and an upgrade data packet is acquired, no matter what state the stylus is in, system upgrade can be immediately performed, and in the process of system upgrade, the stylus is disconnected with the electronic device, so that the stylus cannot be used. For example, the direct system upgrade may be performed without the user's knowledge, and thus, when the stylus is not available during the system upgrade, the user may be considered to be a stylus damage, reducing the user experience.

In view of this, the present application provides a system upgrade method and related apparatus, so that a stylus pen can determine that a software update interface is not opened in a foreground through mode information (whether the software update interface is opened in the foreground) of an electronic device carried in a query message sent by the electronic device, and when an upgrade instruction is not received, the stylus pen waits for a specified upgrade time to perform a system upgrade, and when the stylus pen is in a state of waiting for an upgrade, the stylus pen can be used normally, or the software update interface is not opened in the foreground, and the stylus pen performs a system upgrade according to the received upgrade instruction, thereby improving the experience of a user using the stylus pen.

For purposes of clarity in describing the embodiments of the present application, the words "exemplary" or "such as" are used herein to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

Furthermore, "at least one" means one or more, and "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a alone, a and B together, and B alone, wherein a, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship. "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one (one) of a, b, and c may represent: a, b, or c, or a and b, or a and c, or b and c, or a, b and c, wherein a, b and c can be single or multiple.

The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The same or similar concepts or processes may not be described in detail in some embodiments.

Fig. 7 is a schematic flow chart of a system upgrade method 700 provided by an embodiment of the present application. As shown in fig. 7, the method 700 may include the steps of:

s701, the electronic equipment searches for packages. The searching packet is an upgrade data packet used for upgrading by searching the stylus.

It should be appreciated that each search of the electronic device may be triggered when the electronic device establishes a connection with the stylus communication; or the electronic equipment and the touch pen are in a connection state, and the electronic equipment is triggered under the condition of bright screen. Illustratively, a bright screen search is a search once within 24 hours.

It should also be appreciated that the connection between the electronic device and the stylus may be described with reference to the above related descriptions, and will not be repeated here.

S702, the electronic equipment downloads the upgrade data packet.

It should be understood that, before S701, the electronic device establishes a communication connection with the stylus, and sends respective device information and status information (for example, the device information may include a media access control (medium access control, MAC) address of the stylus, a system version number, a device type, a device name, etc., and the status information may include whether the electronic device is in a state of waiting for a system upgrade) to the other party in the process of establishing the communication connection, and the electronic device may determine current system version information of the stylus from the acquired information. And the electronic equipment requests the server (namely the searching process) according to the acquired system version information, and if a new system version exists, the electronic equipment downloads an upgrade data packet corresponding to the new system version and stores the upgrade data packet in the local.

S703, the electronic device sends a query message to the stylus. Correspondingly, the stylus receives the query message.

The query message is used for inquiring whether the stylus allows upgrading, and an instruction (first identification) for indicating whether the current electronic device is in a foreground mode or a background mode is carried in the query message.

It should be understood that the foreground mode refers to an interface that is displayed as a software update when the electronic device sends a query message (the software update interface is open in the foreground of the electronic device), and the background mode refers to an interface that is not displayed as a software update when the electronic device sends a query message (the software update interface is not open in the foreground of the electronic device).

S704, the touch pen sends a query result to the electronic equipment.

The query result is used for indicating whether the current stylus allows upgrading.

It should be appreciated that the query result is a response message to the query message.

Illustratively, the stylus is not allowed to upgrade, or in the case of insufficient power, etc., and a query result is returned that cannot be upgraded.

Optionally, in the case that the stylus does not allow the upgrade, the flow of the system upgrade is ended.

Optionally, in case the stylus allows for upgrades, the subsequent steps are continued.

S705, the electronic device negotiates upgrade parameters with the stylus.

Illustratively, the parameter negotiation process is: the electronic device sends a parameter negotiation instruction to the touch control pen, and the touch control pen returns relevant parameters of upgrading to the electronic device after receiving the instruction, for example, parameters such as timeout waiting time of checking upgrading data packets, timeout time of restarting upgrading, sending time of the data packets and the like.

S706, the stylus sends an instruction for applying data to the electronic equipment.

S707, after receiving the instruction of applying for data, the electronic device sends an upgrade data packet to the touch control pen.

It should be understood that the upgrade data packet may include a plurality of data packets, for example, data packet 1, data packet 2, data packet 3, …, and data packet N (N is an integer greater than 1). In connection with this example, the above-described instruction for applying for data may be used to apply for transmitting the data packet 1 to the data packet 5 to the electronic device, and correspondingly, the electronic device transmits the data packet 1 to the data packet 5 to the stylus according to the instruction.

S708, the stylus sends a reception completion message to the electronic device.

S709, the electronic device sends a confirmation message to the stylus, where the message is used to notify the stylus that all upgrade data packets have been received.

The receiving completion message is used for indicating that the stylus is completed to receive the upgrade data packet. That is, after receiving the upgrade data packet, the stylus feeds back the received upgrade data packet to the stylus.

In combination with the above example of the data packet, the data packets applied by the stylus are data packet 1 to data packet 5, and correspondingly, the data packets sent by the electronic device to the stylus are data packet 1 to data packet 5. After the stylus receives the data packet, the received data packet is sent to the electronic device, so that the electronic device can confirm whether all or part of the data packets 1 to 5 need to be retransmitted, until the stylus receives all the upgrade data packets (data packets 1 to N), the electronic device sends the confirmation information to the stylus, and the stylus is informed of the fact that all the upgrade data packets have been received.

It should be noted that, after receiving all the upgrade data packets, the stylus determines whether to directly upgrade the system according to specific conditions. The following describes the way of system upgrade after the stylus receives the upgrade data packet in two cases.

In the first case, the instruction carried in the query message indicates that the electronic device is in the foreground mode, that is, the first identifier indicates that the software update interface is opened in the foreground of the electronic device.

The first case is executed: s710, the stylus directly upgrades the system based on the received upgrade data packet.

Optionally, after S710, the stylus sends system version information to the electronic device, where the system version information is used to indicate the current system version of the stylus, and may be, for example, a system version number; the electronic equipment compares the received system version with the system version corresponding to the downloaded upgrade data packet, and if the system version and the system version are the same, the electronic equipment deletes the downloaded upgrade data packet; if the update data packets are different, the downloaded update data packets are saved, and the update data packets are waited for being used after the next triggering of the system update.

In the embodiment of the application, the touch pen can directly upgrade the system according to the received first identifier under the condition of indicating that the electronic equipment is in the foreground mode. It should be understood that when the electronic device is in the foreground mode, it indicates that the user has great willingness to perform system upgrade, and at this time, the stylus can determine that the electronic device is in the foreground mode according to the received first identifier, so that system upgrade is immediately performed, and experience of the user using the stylus is improved.

And secondly, the instruction carried in the query message indicates that the electronic equipment is in a background mode, that is, the first identifier indicates that the software update interface is not opened in the foreground of the electronic equipment.

In one possible implementation, after the query message, the electronic device displays a software update interface in response to the operation of the user, and S711 and S712 are executed when the electronic device determines that the electronic device is still in the software update interface while the stylus receives the upgrade data packet, as follows:

s711, the electronic equipment sends an upgrade instruction to the touch pen, wherein the upgrade instruction is used for indicating the touch pen to upgrade the system. Correspondingly, the stylus receives the upgrade instruction.

S712, the stylus performs system upgrade based on the instruction and the upgrade data packet.

In another possible implementation manner, after confirming that the reception of the upgrade data packet is completed, the electronic device is in the background mode (the software update interface is not opened in the foreground of the electronic device), and S713 is executed, where the stylus enters an upgrade waiting state, and waits for a specified upgrade time to perform a system upgrade.

It should be appreciated that the user may use the stylus normally with the stylus entering an upgrade wait state and the stylus being connected to the electronic device.

It should also be appreciated that the designated upgrade time in the embodiment of the present application may be a time preset on the stylus by the developer, which may be determined by counting the time the user is not using the stylus, for example, 5 a.m. or other time points, which is not limited in this regard.

Optionally, the electronic device displays a software update interface in response to a user operation while the stylus waits for a specified upgrade. At the moment, the electronic equipment acquires that the touch pen is in an upgrade waiting state, and the system version of the touch pen is not the latest version, and then the electronic equipment sends an upgrade instruction to the touch pen; and the stylus performs system upgrading based on the received instruction.

In the embodiment of the application, the touch pen can wait for system upgrade when the electronic equipment is indicated to be in the background mode according to the received first identifier and the preset condition is met (the upgrade instruction is received or the upgrade time is waited for). It should be understood that the electronic device is in a background mode, which indicates that the user does not want to upgrade, at this time, the stylus can wait for a specified upgrade time to upgrade the system (for example, upgrade the system in the 5 am) or upgrade the system according to an upgrade instruction sent by the electronic device when the user opens a software update interface, so that the situation that the stylus cannot be used due to the system upgrade in the process of using the stylus by the user is effectively avoided, and the user experience is improved.

Fig. 8 is a schematic flow chart of another system upgrade method 800 provided by an embodiment of the present application. Before the method 800 shown below, the electronic device and the stylus establish a communication connection, the electronic device may obtain system version information and status information of the stylus, and the electronic device starts searching for an upgrade data packet according to the obtained information, and downloads the upgrade data packet after searching for the upgrade data packet, and stores the upgrade data packet locally. As shown in fig. 8, the method 800 may include S801 and S802, and the steps of the method 800 are described in detail below:

S801, the electronic device sends a first identifier to the stylus, where the first identifier is used to indicate whether the software update interface is opened in a foreground of the electronic device. Correspondingly, the stylus receives the first identification.

It should be appreciated that whether the software update interface described above is open in the foreground of the electronic device indicates whether the current display interface of the electronic device is a software update interface.

It should also be understood that the specific content indicated by the first identifier is determined according to the current display interface when the electronic device sends the first identifier. For example, if the interface displayed by the electronic device is a software update interface, the first identifier indicates that the software update interface is opened in the foreground of the electronic device; the interface displayed by the electronic device is not a software update interface, and the first identifier indicates that the software update interface is not opened in the foreground of the electronic device.

Illustratively, the first identifier may be 1 or 0. For example, a first flag of 1 indicates that the software update interface is open in the foreground of the electronic device (which may also be referred to as the electronic device being in foreground mode), and a first flag of 0 indicates that the software update interface is not open in the foreground of the electronic device (which may also be referred to as the electronic device being in background mode); or, the first identifier is 0, which indicates that the software update interface is opened in the foreground of the electronic device, and the first identifier is 1, which indicates that the software update interface is not opened in the foreground of the electronic device. It should be understood that the first identifier may be represented in other manners, which the present application is not limited to.

S802, when the software updating interface is not opened in the foreground of the electronic equipment, the stylus waits until the preset condition is met to update the system.

The preset conditions comprise: the stylus receives an upgrade instruction from the electronic device, or the stylus reaches a specified upgrade time. The upgrade instruction is used for indicating the stylus to upgrade the system.

It should be appreciated that the above-described software update interface not being opened in the foreground indicates that the current display interface of the electronic device is not a software update interface.

It should also be appreciated that the above-described electronic device sending an upgrade instruction may be triggered when two conditions are satisfied at the same time: 1. the first identifier is used for indicating that the software updating interface is not opened in the foreground of the electronic equipment; 2. the electronic device displays a software update interface in response to a user operation.

In the embodiment of the application, the electronic device indicates whether the interface currently displayed by the electronic device is a software update interface through the first identifier, so that the touch pen receiving the first identifier can perform system upgrade when the first identifier indicates that the software update interface is not opened in the foreground of the electronic device and waits for a preset condition. Under any condition, the system upgrade is directly carried out on the touch pen, so that the situation that the touch pen cannot be used due to upgrade in the using process is effectively avoided, and the experience of a user in using the touch pen is improved.

As an alternative embodiment, the method 800 further includes: and under the condition that the software updating interface is opened at the foreground of the electronic equipment, directly performing system updating without waiting until the preset condition is met.

It should be understood that the preset condition is the same as the preset condition described in S802, and will not be repeated here.

It should also be appreciated that the above described software update interface opens in the foreground of the electronic device to indicate that the current display interface of the electronic device is a software update page.

In the embodiment of the application, the stylus can directly upgrade the system under the condition that the first identifier indicates that the interface displayed by the electronic equipment is a software updating interface. It should be noted that, when the interface displayed by the electronic device is a software update interface, it indicates that a user may have an upgrade intention, at this time, even if the stylus is immediately upgraded, when the stylus cannot be used, the user may not consider that the stylus is damaged, thereby improving the experience of using the stylus by the user.

As an alternative embodiment, the performing the system upgrade includes: performing system upgrade based on an upgrade data packet from the electronic device; and, the method 800 further includes: and under the condition that the stylus allows upgrading, the electronic equipment sends an upgrading data packet to the stylus. Correspondingly, the stylus receives the upgrade data packet.

Optionally, the interface displayed by the first identifier indicates that the interface displayed by the electronic device is a software update interface, and the stylus directly performs system update without waiting after receiving all update data packets. Or, the interface displayed by the electronic device is not a software update interface, and after receiving all the upgrade data packets, the stylus may perform system upgrade in the following two cases: 1. when the upgrade instruction is continuously received, upgrading is carried out; 2. and if the upgrade instruction is not received, waiting for the upgrade time to upgrade the system.

As an alternative embodiment, the stylus sends a reception completion message to the electronic device, the reception completion message being used to instruct the stylus that the reception of the upgrade data packet is completed. Correspondingly, the electronic device receives a message from the stylus that the reception is completed.

The description of the receiving completion message may refer to the description of the receiving completion message in the method 700, which is not repeated herein.

As an optional embodiment, in a case that it is determined that the stylus receives the upgrade data packet, the electronic device detects whether the software update interface is opened in the foreground of the electronic device; if the software updating interface is opened at the foreground of the electronic equipment, the electronic equipment sends an upgrading instruction to the touch control pen, and the upgrading instruction is used for indicating the touch control pen to upgrade the system. Correspondingly, the stylus receives the upgrade instruction.

In an exemplary embodiment, when it is determined that the stylus receives the upgrade data packet, the electronic device directly sends the upgrade instruction when the interface currently displayed by the electronic device is a software update interface.

It should be noted that, after receiving the upgrade data packet for a period of time, the electronic device displays a software update interface in response to the operation of the user. The electronic device needs to determine whether to send an upgrade instruction according to the state of the stylus and the current system version of the stylus: 1. when the touch control pen is in a state of waiting for upgrading time to upgrade the system and the current system version is not a new system version (the system version corresponding to the upgrading data packet), the electronic equipment sends an upgrading instruction; 2. if the current system version of the stylus is a new system version, no upgrade instruction is sent, that is, when the electronic device responds to the operation of the user and displays a software update interface, the stylus is successfully upgraded at the appointed upgrade time.

As an alternative embodiment, the first identifier is carried in a query message, where the query message is used to query whether the stylus allows upgrading; the method 800 further includes: the stylus sends a response message to the electronic device to the query message, the response message indicating whether the stylus allows the upgrade. Correspondingly, the electronic device receives the response message.

It should be appreciated that the condition of whether the stylus allows upgrading may refer to the related description or the known technology in the method 700, and will not be described herein.

As an alternative embodiment, the method 800 further includes: after the system upgrade is completed, the stylus sends system version information to the electronic device, the system version information being used to indicate the current system version of the stylus. Correspondingly, the electronic equipment receives the system version information and determines whether to delete the upgrade data packet based on the system version information.

The above-described system version information may be a system version number, for example.

It should be understood that after the stylus completes the system upgrade, the current system version of the stylus is the new system version, or the system version of the stylus is still the version prior to the system upgrade. That is, after the system upgrade is completed, there are two cases that the upgrade of the stylus is successful or the upgrade fails: 1. after the upgrade is successful, the electronic equipment can delete the downloaded upgrade data packet based on the received system version information; 2. after the upgrade fails, the electronic equipment does not delete the downloaded upgrade data packet so as to be used when the system upgrade is performed by the stylus next time.

It should be understood that the sequence numbers of the above processes do not mean the order of execution, and the execution order of the processes should be determined by the functions and internal logic of the processes, and should not be construed as limiting the implementation process of the embodiments of the present application.
