[0038] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, although the disclosure in the present application is introduced according to one or more exemplary examples, it should be understood that each aspect of these disclosures can also constitute a complete implementation method separately.

[0039] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0040] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0041] In the related art, when the working mode of the WiFi chip is switched from one mode to another mode, the user is required to manually control the hardware switch corresponding to the other mode to turn on (or implement it through a serial port AT command), which makes the user operation complicated.

[0042] In order to simplify user operations in the process of switching the working mode of a WiFi chip from one mode to another, in the present application, the inventors conceived of configuring a near field communication (NFC) tag for the WiFi chip, writing mode switching information in the NFC tag, and when the distance between the NFC tag and the WiFi chip is close, the mode of the WiFi chip can be switched according to the mode switching information in the NFC tag.

[0043] Figure 1 This is an application scenario diagram of the mode switching method of the WiFi chip provided in the embodiment of the present application. Figure 1As shown, it includes: NFC tag, system on chip (SoC), NFC detection chip, WiFi chip. The NFC detection chip and WiFi chip can be set on the SoC.

[0044] Optionally, a WiFi chip may be included in the NFC detection chip.

[0045] Among them, SoC, also known as system on chip, is an integrated circuit with a dedicated purpose, which contains all the contents of a complete system and embedded software.

[0046] When the distance between the NFC tag and the NFC detection chip is close, the NFC detection chip can receive mode switching information, and the SoC can switch the mode of the WiFi chip according to the mode switching information, thereby simplifying user operations and avoiding the need for users to manually control the corresponding hardware switch to turn on when switching the working mode of the WiFi chip from one mode to another.

[0047] The mode switching method of the WiFi chip provided by the present application is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0048] Figure 2 The process of the mode switching method of the WiFi chip provided in the embodiment of the present application Figure 1 .like Figure 2 As shown, the method includes:

[0049] S201. Receive mode switching information sent by an NFC tag, where the mode switching information is used to instruct to switch the mode of the WiFi chip to a target WiFi mode.

[0050] The mode switching method of the WiFi chip provided in the embodiment of the present application can be applied to various electronic devices including SoC, such as routers, mobile terminals, smart phones, PDAs, handheld devices with wireless communication functions, computing devices, vehicle-mounted devices, wearable devices, and household appliances such as televisions, stereos, and refrigerators. The specific form of the electronic device is not limited in the embodiment of the present application, as long as the electronic device has a WiFi chip.

[0051] The NFC tag is the tag corresponding to the target WiFi mode.

[0052] For example, an NFC tag may be a tag specially configured for an electronic device.

[0053] For example, the NFC tag may also be an NFC module in a mobile phone, and the NFC module is a module implemented by hardware and / or software. When the NFC tag is an NFC module in a mobile phone, the user can switch information through a custom editing mode.

[0054] The modes of the WiFi chip include but are not limited to at least one of the following modes: AP mode, STA mode, AP and STA coexistence mode, Mesh mode, Monitor (MON) mode, Independent Basic Service Set (IBSS) mode (Ad-hoc mode), Wireless Distribution System (WDS) mode, custom mode, etc. The custom mode may be, for example, a sniffer filtering air broadcast packet mode.

[0055] The target WiFi mode may be any one of the at least one mode mentioned above.

[0056] Optionally, when the NFC tag is a tag specially configured for the electronic device, if there are multiple modes of the WiFi chip, there may also be multiple NFC tags, wherein the target WiFi modes indicated by the multiple NFC tags are different.

[0057] S202: Obtain a target identifier of a target WiFi mode from the mode switching information.

[0058] Optionally, the mode switching information may include a target identifier of a target WiFi mode, may include encrypted information obtained by encrypting the target identifier of the target WiFi mode, may include mapping information corresponding to the target identifier, and may include preset information.

[0059] For example, when the mode switching information includes the target identifier, the target identifier may be directly acquired from the mode switching information.

[0060] For example, when the mode switching information includes encrypted information obtained by encrypting the target identifier, the encrypted information is decrypted according to a preset decryption algorithm to obtain the target identifier of the target WiFi mode.

[0061] For example, when the mode switching information includes mapping information corresponding to the target identifier, the mapping information is obtained from the mode switching information, wherein the mapping information indicates the target identifier; the mode identifier corresponding to the mapping information is searched in a pre-stored mapping list, and the mode identifier corresponding to the mapping information is determined as the target identifier of the target WiFi mode. The mapping list includes multiple mapping information and the mode identifier corresponding to each mapping information.

[0062] For example, when the mode switching information includes a preset information, the electronic device counts the total number of times the preset information is currently received, searches for the mode identifier corresponding to the total number of times in the pre-stored information list, and determines the mode identifier corresponding to the total number of times as the target identifier of the target WiFi mode. The information list includes multiple times and the mode identifier corresponding to each time.

[0063] It should be noted that when the mode switching information includes a preset information, if the total number of times is greater than the preset threshold, the electronic device will restart the counting from 0. For example, when the modes of the WiFi chip include AP mode, STA mode, and Mesh mode, when the preset information is received for the first time, the target identifier may be the identifier of the AP mode, when the preset information is received for the second time, the target identifier may be the identifier of the STA mode, and when the preset information is received for the third time, the target identifier may be the identifier of the Mesh mode. For example, when the preset threshold is equal to 3, starting from 0, when the preset information is received for the first time, the target identifier may be the identifier of the AP mode, when the preset information is received for the second time, the target identifier may be the identifier of the STA mode, and when the preset information is received for the third time, the target identifier may be the identifier of the Mesh mode. Repeating this process can enable WiFi to cyclically switch between multiple modes.

[0064] Optionally, after the target identifier is acquired, the target identifier may be recorded and stored first.

[0065] S203, obtaining the target firmware corresponding to the target identifier, and controlling the WiFi chip to run the target firmware in the target WiFi mode.

[0066] Specifically, the operating system in the SoC initializes the WiFi chip, obtains the target firmware corresponding to the target identifier, and controls the WiFi chip to run the target firmware in the target WiFi mode.

[0067] Specifically, obtaining the target firmware corresponding to the target identifier includes: determining whether the target identifier is identical to the identifier of the current WiFi mode of the WiFi chip; if not, executing S203. Further, if identical, stopping executing S203.

[0068] Acquiring the target firmware corresponding to the target identifier may include: a boot ROM acquires the target firmware corresponding to the target identifier from a flash memory (FLASH), and downloads the target firmware to a random access memory (Random Access Memory, RAM).

[0069] The flash memory stores firmware corresponding to a plurality of identifiers, each firmware has a different storage address in the flash memory, and the firmware corresponding to the plurality of identifiers includes a target firmware corresponding to the target identifier.

[0070] Specifically, a list including multiple mode identifiers and storage addresses corresponding to each mode identifier can be pre-stored in the electronic device (or SoC), and the multiple mode identifiers include a target identifier; the boot program can search the list according to the target identifier to obtain the storage address corresponding to the target identifier, and obtain the target firmware corresponding to the target identifier from the storage address corresponding to the target identifier.

[0071] It should be noted that in this application, when the mode of the WiFi chip is different, the electronic device has different functions. For example, when the electronic device is a device including a High Definition Multimedia Interface (HDMI), the mode of the WiFi chip in the device can be switched to AP mode through an NFC tag, so that the electronic device can also be used as an AP device for transmitting WiFi signals. The mode of the WiFi chip in the device can also be switched to STA mode through an NFC tag, so that the electronic device can be used as a STA device for WIFI multicast video formation.

[0072] exist Figure 2 In the mode switching method of the WiFi chip provided in the embodiment, the mode switching information sent by the near field communication NFC tag is received, and the target identifier of the target WiFi mode is obtained from the mode switching information; the target firmware corresponding to the target identifier is obtained, and the WiFi chip is controlled to run the target firmware in the target WiFi mode, so that the WiFi chip has the target WiFi mode. In practical applications, for example, when a user holds an NFC tag and makes the NFC tag touch an electronic device (i.e., the distance between the NFC tag and the electronic device is less than or equal to the preset distance), the mode switching method of the WiFi chip can be executed, thereby realizing the mode switching of the WiFi chip, simplifying the user's operation.

[0073] In actual applications, as technology develops, a single hardware may have dual systems (i.e., the number of systems is equal to 2) or multiple systems (the number of systems is greater than 2). For example, USB may switch between different devices or buses as the system switches. Similarly, WiFi chips may switch to different modes as the system switches.

[0074] Combine the following Figure 3 Explains how to switch the WiFi chip mode between different systems.

[0075] Figure 3 The process of the mode switching method of the WiFi chip provided in the embodiment of the present application Figure 2 .like Figure 3 As shown, the method includes:

[0076] S301, control the NFC detection chip to turn on.

[0077] When the WiFi chip works in a certain mode, the NFC detection chip can handle the closed state (i.e., the power-off state). Since the NFC detection chip is in the open state (i.e., the power-on state) for a long time, it wastes the power of the electronic device, which will cause the battery life of the electronic device to be reduced. Therefore, in this application, when the mode of the WiFi chip needs to be switched, the NFC detection chip is controlled to be turned on, which can save the power of the electronic device and extend the battery life of the electronic device.

[0078] S302: Receive mode switching information sent by the NFC tag through the NFC detection chip. The mode switching information is used to instruct to switch the mode of the WiFi chip to the target WiFi mode.

[0079] Specifically, the execution method of S302 is similar to the execution method of S201, and the execution process of S302 is not repeated here.

[0080] S303: Obtain a target identifier of the target WiFi mode from the mode switching information.

[0081] Specifically, the execution method of S303 is the same as the execution method of S202, and the execution process of S303 is not repeated here.

[0082] S304: Determine whether the target WiFi mode matches the current operating system.

[0083] If not, execute S305; otherwise, execute S306.

[0084] Optionally, before S304, the process may further include: determining whether the target identifier is identical to an identifier of a current WiFi mode of the WiFi chip; if they are not identical, executing S304.

[0085] Optionally, determining whether the target WiFi mode matches the current operating system includes: determining whether the target identifier is included in at least one mode identifier corresponding to the system identifier of the current operating system; if so, the target WiFi mode matches the current operating system; if not, the target WiFi mode does not match the current operating system. Among them, the electronic device (or SoC) can pre-store system identifiers of multiple operating systems and at least one mode identifier corresponding to each system identifier. For example, if at least one mode identifier corresponding to the system identifier of the current operating system includes the target identifier, the target WiFi mode matches the current operating system. For example, if at least one mode identifier corresponding to the system identifier of the current operating system does not include the target identifier, the target WiFi mode does not match the current operating system.

[0086] S305: Determine a target operating system corresponding to the target WiFi mode, run the target operating system, obtain a target firmware corresponding to the target identifier, and control the WiFi chip to run the target firmware in the target WiFi mode.

[0087] Optionally, before, after, or during running the target operating system, it may also include: determining whether the target WiFi mode matches the host bus currently connected to the WiFi chip; if not, switching the host bus currently connected to the WiFi chip to a host bus matching the target WiFi mode.

[0088] Currently, WiFi chips support multiple host buses, such as Universal Serial Bus (USB), Secure Digital Input and Output (SDIO) bus, Universal Asynchronous Receiver / Transmitter (UART) bus, high-speed serial computer expansion bus (peripheral component interconnect express, PCIE), Serial Peripheral Interface (SPI) bus, I2C bus, etc.

[0089] Optionally, a bus identifier may be configured for each host bus, and a mapping relationship between multiple bus identifiers and at least one mode identifier corresponding to each bus identifier may be pre-stored, wherein the host bus indicated by the bus identifier matches the mode indicated by the mode identifier corresponding to the bus identifier.

[0090] Specifically, the identifier of the host bus currently connected to the WiFi chip can also be pre-stored

[0091] Furthermore, the identifier of the host bus currently connected to the WiFi chip can be obtained, and it can be determined whether at least one mode identifier corresponding to the identifier of the host bus currently connected to the WiFi chip in the above mapping relationship includes the target mode of the target WiFi mode; if so, the target WiFi mode matches the host bus currently connected to the WiFi chip; if not, the target WiFi mode does not match the host bus currently connected to the WiFi chip.

[0092] In the present application, it is determined whether the target WiFi mode matches the host bus currently connected to the WiFi chip; if not, the host bus currently connected to the WiFi chip is switched to a host bus that matches the target WiFi mode. This allows different host buses to be used for data communication when the throughput of electronic devices is different, thereby improving the data transmission efficiency during data transmission.

[0093] S305: Obtain target firmware corresponding to the target identifier, and control the WiFi chip to run the target firmware in the target WiFi mode.

[0094] Determining the target operating system corresponding to the WiFi mode may include: determining the target system identifier corresponding to the target identifier of the target WiFi mode among at least one mode identifier corresponding to each of the system identifiers of multiple operating systems, and determining the operating system with the target system identifier as the target operating system corresponding to the target WiFi mode.

[0095] Running the target operating system may include: running the target operating system through a boot system in the electronic device.

[0096] Specifically, the method of obtaining the target firmware corresponding to the target identifier and controlling the WiFi chip to run the target firmware in the target WiFi mode is similar to the method in S203 and will not be repeated here.

[0097] It should be noted that in this application, the electronic device can have a variety of WiFi functional device forms. For example, when the WiFi chip mode is AP mode, the target operating system is a router system (openwrt system), the target firmware can be WiFi AP firmware or the firmware corresponding to the WiFi AP and STA coexistence mode, and the electronic device has an AP functional device form. For example, when the WiFi chip mode is STA mode, the target operating system is the mbedos RTOS system, the target firmware can be the WIFI STA firmware, and the electronic device has a STA functional device form.

[0098] exist Figure 3 In the mode switching method of the WiFi chip provided in the embodiment, it is determined whether the target WiFi mode matches the current operating system. If not, the target operating system corresponding to the target WiFi mode is determined, the target operating system is run, and the target firmware corresponding to the target identifier is obtained, and the WiFi chip is controlled to run the target firmware in the target WiFi mode. The mode switching method of the WiFi chip provided in the present application can be applied to electronic devices with dual systems or multiple systems, which expands the application scope of the mode switching method of the WiFi chip and can better meet the needs of the market.
