It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the application described herein may be implemented, for example, in sequences other than those illustrated or otherwise described herein.

In the related art, when the operation mode of the WiFi chip is switched from one mode to another mode, a user is required to manually control a hardware switch corresponding to the other mode to be turned on (or through a serial AT command), thereby complicating the user operation.
In order to simplify the user operation in the process of switching the working mode of the WiFi chip from one mode to another mode, the inventor thinks that a Near Field Communication (NFC) tag is configured for the WiFi chip, mode switching information is written in the NFC tag, and when the NFC tag is close to the WiFi chip, the mode of the WiFi chip can be switched according to the mode switching information in the NFC tag.
Fig. 1 is an application scenario diagram of a mode switching method of a WiFi chip provided by an embodiment of the present application. As shown in fig. 1, the System on Chip (SoC) includes an NFC tag, an NFC detection Chip, and a WiFi Chip. The NFC detection chip and the WiFi chip may be disposed on the SoC.
Optionally, a WiFi chip may be included in the NFC detection chip.
Among them, the SoC is also called a system-on-chip, which is an integrated circuit with a dedicated target, containing the complete system and having the entire contents of embedded software.
When the NFC label is closer to the NFC detection chip, the NFC detection chip can receive the mode switching information, and the SoC can switch the mode of the WiFi chip according to the mode switching information, so that user operation is simplified, and the situation that a user is required to manually control a corresponding hardware switch to be turned on in the process of switching the working mode of the WiFi chip from one mode to the other mode is avoided.
The mode switching method of the WiFi chip provided by the application is described in detail in specific embodiments. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.
Fig. 2 is a flowchart of a mode switching method of a WiFi chip according to an embodiment of the present application. As shown in fig. 2, the method includes:
S201, receiving mode switching information sent by the NFC tag, wherein the mode switching information is used for indicating to switch the mode of the WiFi chip to a target WiFi mode.
The mode switching method of the WiFi chip provided by the embodiment of the application can be applied to various types of electronic equipment including SoC, such as routers, mobile terminals, smart phones, palm (Personal DIGITAL ASSISTANT, PDA for short), handheld equipment with wireless communication function, computing equipment, vehicle-mounted equipment, wearable equipment, televisions, sound equipment, refrigerators and other household appliances. The embodiment of the application does not limit the specific form of the electronic equipment, so long as the electronic equipment is provided with a WiFi chip.
The NFC tag is a tag corresponding to the target WiFi mode.
For example, NFC tags may be specially configured tags for electronic devices.
For example, the NFC tag may also be an NFC module in a mobile phone, where the NFC module is a module implemented in hardware and/or software. When the NFC tag is in the NFC module in the mobile phone, the user can switch information through the custom editing mode.
The mode of the WiFi chip includes, but is not limited to, at least one of an AP mode, a STA mode, a coexistence mode of the AP and the STA, a Mesh mode, a Monitor (MON) mode, an independent basic service set (INDEPENDENT BASIC SERVICE SET, IBSS) mode (Ad-hoc mode), a wireless distribution system (Wireless Distribution System, WDS) mode, a custom mode, and the like. The custom mode may be, for example, sniffer filtered over-the-air packet mode.
The target WiFi mode may be any one of the at least one modes described above.
Optionally, when the NFC tag is a tag specifically configured for the electronic device, if there are multiple modes of the WiFi chip, there may be multiple NFC tags. The target WiFi modes indicated by the NFC tags are different from each other.
S202, acquiring a target identifier of a target WiFi mode from the mode switching information.
Optionally, the mode switching information may include a target identifier of the target WiFi mode, encrypted information obtained by encrypting the target identifier of the target WiFi mode, mapping information corresponding to the target identifier, and preset information.
For example, when the target identifier is included in the mode switching information, the target identifier may be directly acquired from the mode switching information.
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.
For example, when the mode switching information includes mapping information corresponding to the target identifier, the mapping information is acquired 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 comprises a plurality of mapping information and a mode identifier corresponding to each mapping information.
For example, when the mode switching information includes one piece of preset information, the electronic device counts the total number of times of the preset information currently received, searches a mode identifier corresponding to the total number of times in a pre-stored information list, and determines the mode identifier corresponding to the total number of times as a target identifier of the target WiFi mode. The information list comprises a plurality of times and mode identifications corresponding to the times.
It should be noted that, when the mode switching information includes one preset information, if the total number of times is greater than the preset threshold, the electronic device starts to count again from 0. For example, when the modes of the WiFi chip include an AP mode, an STA mode, and a Mesh mode, the target identifier may be an identifier of the AP mode when the preset information is received for the first time, the target identifier may be an identifier of the STA mode when the preset information is received for the second time, and the target identifier may be an identifier of the Mesh mode when the preset information is received for the third time. For example, when the preset threshold is equal to 3, starting from 0, when preset information is received for the first time, the target identifier may be an identifier of an AP mode, when preset information is received for the second time, the target identifier may be an identifier of an STA mode, and when preset information is received for the third time, the target identifier may be an identifier of a Mesh mode, so that WiFi can be cyclically switched among multiple modes.
Alternatively, after the target identifier is acquired, the target identifier may be recorded and stored first.
S203, acquiring target firmware corresponding to the target identifier, and controlling the WiFi chip to operate the target firmware in a target WiFi mode.
Specifically, an operating system in the SoC initializes the WiFi chip, acquires target firmware corresponding to the target identifier, and controls the WiFi chip to operate the target firmware in a target WiFi mode.
Specifically, the target firmware corresponding to the target identifier is obtained, which includes judging whether the target identifier is the same as the identifier of the current WiFi mode of the WiFi chip, and executing S203 if the target identifier is not the same as the identifier of the current WiFi mode of the WiFi chip. Further, if the same, execution of S203 is stopped.
The obtaining the target firmware corresponding to the target identifier may include a boot strap program (BOOTROM) obtaining the target firmware corresponding to the target identifier from a FLASH memory (FLASH), and downloading the target firmware into a random access memory (Random Access Memory, RAM).
The flash memory stores a plurality of firmware corresponding to the identifiers, each firmware has different storage addresses in the flash memory, and the firmware corresponding to the identifiers comprises target firmware corresponding to the target identifier.
Specifically, the electronic device (or SoC) may store in advance a list including a plurality of mode identifiers and storage addresses corresponding to each mode identifier, where the plurality of mode identifiers include target identifiers, and the bootstrap program may search the list according to the target identifiers to obtain the storage addresses corresponding to the target identifiers, and obtain target firmware corresponding to the target identifiers from the storage addresses corresponding to the target identifiers.
It should be noted that, in the present application, when the modes of the WiFi chip are different, the electronic device has different functions. For example, when the electronic device is a device including a high-definition multimedia interface (High Definition Multimedia Interface, HDMI), the mode of the WiFi chip in the device may be switched to the AP mode by the NFC tag, so that the electronic device may also be used as an AP device to transmit a WiFi signal outwards. The mode of the WiFi chip in the device can be switched to the STA mode through the NFC tag, so that the electronic device can be used as the STA device for WIFI multicast video construction.
In the mode switching method of the WiFi chip provided in the embodiment of fig. 2, mode switching information sent by a near field communication NFC tag is received, a target identifier of a target WiFi mode is obtained from the mode switching information, a target firmware corresponding to the target identifier is obtained, and the WiFi chip is controlled to operate the target firmware in the target WiFi mode, so that the WiFi chip has the target WiFi mode. In practical applications, for example, a user holds the NFC tag, so that the NFC tag contacts the electronic device (i.e., the distance between the NFC tag and the electronic device is smaller than or equal to a preset distance), so that the mode switching method of the WiFi chip is performed, thereby implementing mode switching of the WiFi chip, and simplifying operation of the user.
In practical applications, with the development of technology, a single hardware may have two 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 also switch between different devices or buses with the switching of systems. The WiFi chip can also switch to different modes along with the system switching.
How to switch the mode of the WiFi chip between different systems is described below in connection with fig. 3.
Fig. 3 is a flowchart two of a mode switching method of a WiFi chip provided by an embodiment of the application. As shown in fig. 3, the method includes:
s301, controlling the NFC detection chip to be started.
When the WiFi chip operates in a certain mode, the NFC detection chip may process the off state (i.e., the power-off state). When the NFC detection chip is in an on state (i.e., an energized state) for a long period of time, the electric quantity of the electronic device is wasted, which results in a reduction in the duration of the electronic device. Therefore, in the application, when the mode of the WiFi chip is required to be switched, the NFC detection chip is controlled to be started, the electric quantity of the electronic equipment can be saved, and the duration of the electronic equipment can be prolonged.
S302, receiving mode switching information sent by the NFC tag through the NFC detection chip. The mode switching information is used for indicating to switch the mode of the WiFi chip to a target WiFi mode.
Specifically, the execution method of S302 is similar to the execution method of S201, and the execution process of S302 is not described here again.
S303, acquiring a target identifier of a target WiFi mode from the mode switching information.
Specifically, the execution method of S303 is the same as the execution method of S202, and the execution process of S303 is not described here again.
S304, judging whether the target WiFi mode is matched with the current operating system.
If not, S305 is executed, otherwise S306 is executed.
Optionally, before S304, judging whether the target identifier is the same as the identifier of the current WiFi mode of the WiFi chip, and if not, executing S304.
Optionally, judging whether the target WiFi mode is matched with the current operating system or not includes judging whether at least one mode identifier corresponding to the system identifier of the current operating system comprises the target identifier or not, if yes, the target WiFi mode is matched with the current operating system, and if not, the target WiFi mode is not matched with the current operating system. The electronic device (or SoC) may store, in advance, system identifiers of a plurality of 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 is matched with 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 is not matched with the current operating system.
S305, determining a target operating system corresponding to the target WiFi mode, running the target operating system, acquiring target firmware corresponding to the target identifier, and controlling the WiFi chip to run the target firmware in the target WiFi mode.
Optionally, before, after or during the operation of the target operating system, the method further comprises the steps of judging whether the target WiFi mode is matched with a host bus currently connected with the WiFi chip, and if not, switching the host bus currently connected with the WiFi chip into a host bus matched with the target WiFi mode.
Currently, wiFi chips support a variety of host buses, such as universal serial bus (Universal Serial Bus, USB), secure digital input output (Secure Digital Input and Output, SDIO) bus, universal asynchronous receiver Transmitter (Universal Asynchronous Receiver/Transmitter, UART) bus, high-speed serial computer expansion bus (PERIPHERAL COMPONENT INTERCONNECT EXPRESS, PCIE), serial peripheral interface (SERIAL PERIPHERAL INTERFACE, SPI) bus, I2C bus, and the like.
Alternatively, a bus identifier may be configured for each host bus, and a mapping relationship between a plurality of bus identifiers and at least one mode identifier corresponding to each bus identifier may be stored in advance. The host bus indicated by the bus identifier is matched with the mode indicated by the mode identifier corresponding to the bus identifier.
Specifically, the identifier of the host bus currently connected with the WiFi chip may also be stored in advance
Further, the identification of the host bus currently connected with the WiFi chip can be obtained, whether at least one mode identification corresponding to the identification of the host bus currently connected with the WiFi chip comprises a target mode of a target WiFi mode or not in the mapping relation is judged, if yes, the target WiFi mode is matched with the host bus currently connected with the WiFi chip, and if not, the target WiFi mode is not matched with the host bus currently connected with the WiFi chip.
According to the method and the device for judging whether the target WiFi mode is matched with the host bus of the WiFi chip currently, if not, the host bus of the WiFi chip currently connected is switched to the host bus matched with the target WiFi mode, and when the throughput of the electronic equipment is different, data communication can be carried out by adopting different host buses, so that the data transmission efficiency in data passing is improved.
S305, acquiring target firmware corresponding to the target identifier, and controlling the WiFi chip to operate the target firmware in a target WiFi mode.
Determining the target operating system corresponding to the WiFi mode may include determining, in at least one mode identifier corresponding to each of system identifiers of the plurality of operating systems, a target system identifier corresponding to a target identifier of the target WiFi mode, and determining the operating system having the target system identifier as a target operating system corresponding to the target WiFi mode.
Running the target operating system may include running the target operating system through a boot system in the electronic device.
Specifically, the method for acquiring the target firmware corresponding to the target identifier and controlling the WiFi chip to operate the target firmware in the target WiFi mode is similar to the method in S203, and will not be described herein.
In the present application, the electronic device may have a plurality of WiFi function device modes. For example, when the mode of the WiFi chip is the AP mode, the target operating system is a router system (openwrt system), and the target firmware may be WiFi AP firmware or firmware corresponding to the WiFi AP and STA coexistence mode, where the electronic device has an AP function device configuration. For example, when the mode of the WiFi chip is the STA mode, the target operating system is mbedos RTOS systems, and the target firmware may be WiFi STA firmware, where the electronic device has an STA function device form.
In the mode switching method of the WiFi chip provided in the embodiment of fig. 3, whether the target WiFi mode is matched with the current operating system is determined, if not, the target operating system corresponding to the target WiFi mode is determined, the target operating system is operated, and the target firmware corresponding to the target identifier is obtained, so that the mode switching method of the WiFi chip provided in the application can be applied to electronic devices with dual systems or multiple systems, the application range of the mode switching method of the WiFi chip is expanded, and the market demand can be better satisfied.
