To facilitate an understanding of the embodiments disclosed herein, some concepts related to the embodiments of the present application will be first explained. The description of these concepts includes, but is not limited to, the following.
Wi-Fi middleware hostapd: the application is a daemon program of a user space, and is mainly used on an Access Point (AP) and an authentication server, and the daemon program is used as an authentication server of the AP and is responsible for controlling access and authentication of management stations (for example, generally, a PC with a wireless network card).

Wi-Fi firmware (firmware): is a type of software embedded in a hardware device. Typically it is in a flash memory or EEPROM or PROM located in an Application Specific Integrated Circuit (ASIC) or Programmable Logic Device (PLD), some of which can be updated by the user. The method can be applied to very wide electronic products, and the shadow can be seen from a remote controller, a calculator, a keyboard and a hard disk in a computer, and even an industrial robot.
Based on the above description, an embodiment of the present application proposes a Wi-Fi management method as shown in fig. 2, where the method is applied to a terminal device, where the terminal device includes a Wi-Fi software architecture as shown in fig. 3, a web application (AP web application and STA web application), a Wi-Fi Manager (Manager), a Wi-Fi Driver, and a Wi-Fi Firmware, where the Wi-Fi Driver is hosted by the Wi-Fi Manager, and the Wi-Fi management method may include steps S201 to S203:
s201: and the network application program receives the control instruction and sends the control instruction to the Wi-Fi Manager, wherein the control instruction comprises a control instruction corresponding to the wireless access point or a control instruction corresponding to the site.
The user inputs a control instruction through the network application program, and the network application program forwards the control instruction to the Wi-Fi Manager. The network application may be understood as an application that may call (or turn on) a network hotspot (e.g., an AP network application in fig. 3), and/or may call (or turn on/use) an application use of Wi-Fi (e.g., an STA network application in fig. 3). When a user inputs a control instruction through an AP network application program of the terminal equipment, the control instruction is a control instruction corresponding to the wireless access point. When a user inputs a control instruction through an STA network application program of the terminal equipment, the control instruction is a control instruction corresponding to the station.
It should be noted that the control instruction is a control instruction corresponding to the AP, and may be understood as a control instruction received when the terminal device is used as the AP, for example, a network hotspot opening instruction. Similarly, the control instruction is a control instruction corresponding to a Station (STA), and may be understood as a control instruction received when the terminal device is taken as an STA, for example, a Wi-Fi instruction is turned on. In an application scenario, the same terminal device may serve as both an STA and an AP. As shown in fig. 4, fig. 4 is a schematic diagram of an application scenario. In the application scenario, the terminal device 1 serves as an AP to provide a wireless network for the terminal device 2, and meanwhile, in the application scenario, the terminal device 1 also serves as a network hotspot where an STA is connected to the terminal device 3. Wi-FiDriver is hosted by the Wi-Fi Manager can be understood as the Wi-FiDriver is hosted by the Wi-Fi Manager process.
In a possible implementation, when the control instruction is a control instruction corresponding to the STA, the control instruction may include: an instruction to turn on STA mode, an instruction to scan Wi-Fi network, an instruction to connect Wi-Fi network, an instruction to disconnect Wi-Fi network, and an instruction to turn off STA mode.
In one possible implementation, the control instruction is a control instruction corresponding to the AP, and the control instruction may include: an instruction for opening the AP mode, an instruction for opening the hot spot, an instruction for closing the hot spot and an instruction for closing the AP mode.
In one possible implementation, the network Application receives the control command and invokes an Application Programming Interface (API) to send the control command to the Wi-Fi Manager. By the method, the network application program transmits the control instruction to the Wi-Fi Manager in a function call (function call) mode, and the efficiency of transmitting the control instruction to the Wi-Fi Manager is improved.
S202: and the Wi-Fi Manager verifies whether the control instruction is legal or not, and sends the control instruction to the Wi-Fi Driver after verifying that the control instruction is legal.
The Wi-Fi Manager verifies whether the control instruction is legal or not by using a logic unit of the Wi-Fi Manager, namely, whether the control instruction can be executed by the terminal equipment or not is verified, if the control instruction can be executed by the terminal equipment, the control instruction is determined to be legal, and the control instruction is sent to the Wi-Fi Driver.
The verification of whether the control instruction is legal can be understood as verifying whether the control instruction is wrong. For example, the terminal device is not configured with a function as an STA, i.e., cannot connect to Wi-Fi (such as a desktop computer). And if the user inputs an instruction for opening the terminal device Wi-Fi, the control instruction is an error instruction, namely the control instruction is illegal.
Illustratively, the terminal device may be an STA, and the Wi-Fi band that the STA supports scanning at this time is the Wi-Fi of the 4th Generation mobile communication (4G) band. If the Wi-Fi Manager receives a control command for scanning a Wi-Fi signal in an FR1 band, and the FR1 band is the 5th Generation mobile communication (5G) band, the Wi-Fi Manager may determine that the control command is illegal.
In one possible implementation, after the Wi-Fi Manager verifies that the control instruction is legal, the Wi-Fi Manager can call the second API to send the control instruction to the Wi-Fi Driver. By the method, the Wi-Fi Manager transmits the control instruction to the Wi-Fi Driver in a function call (function call) mode, and the efficiency of transmitting the control instruction to the Wi-Fi Driver by the Wi-Fi Manager is improved.
S203: and the Wi-Fi Driver drives the Wi-Fi Firmware to execute the corresponding operation of the control instruction according to the control instruction.
The Wi-Fi over receives a legal control instruction sent by the Wi-Fi Manager, and drives the Wi-Fi Firmware to execute the control instruction according to the legal control instruction, namely the Wi-Fi Firmware executes the operation corresponding to the control instruction.
In the embodiment of the application, after the terminal device receives a control instruction input by a user through a network application program, the network application program sends the control instruction to the Wi-Fi Manager in a function calling mode, and after the Wi-Fi Manager verifies that the control instruction is legal, the control instruction is sent to the Wi-Fi Driver in a function calling mode, so that the Wi-Fi Driver drives the Wi-Fi Firmware to execute corresponding operation of the control instruction according to the control instruction. By the method, the instruction transmission process of receiving the control instruction and executing the operation corresponding to the control instruction by the terminal is simplified, and the efficiency of managing and operating Wi-Fi or network hotspots in the RTOS environment is improved. Meanwhile, due to the fact that the transmission process of the control command is simplified, the Wi-Fi software architecture (comprising the network application program, the Wi-Fi Manager, the Wi-Fi Driver and the Wi-Fi Firmware) occupies a small memory of the terminal device, and is more suitable for the terminal device (such as IoT device) with the small memory.
Based on the above description, an embodiment of the present application provides another Wi-Fi management method as shown in fig. 5, where the method is applied to a terminal device, and the terminal device includes: the Wi-Fi management method comprises the following steps of S501-S506, wherein the Wi-Fi Manager is hosted by the Wi-Fi Manager, the control instruction carries an identifier of the control instruction, the Wi-Fi Manager comprises a state machine, and the method comprises the following steps:
s501: and the network application program receives the control instruction and sends the control instruction to the Wi-Fi Manager, wherein the control instruction comprises a control instruction corresponding to the wireless access point AP or a control instruction corresponding to the station STA.
The specific implementation manner of step S501 may refer to the specific implementation manner of step S201 in the foregoing embodiment, and will not be described in detail herein.
S502: and the Wi-Fi Manager determines the type of the control instruction based on the identification of the control instruction, wherein the type of the control instruction comprises a control instruction corresponding to the AP and a control instruction corresponding to the STA.
The identifier of the control command may be understood as a character or a character string that uniquely corresponds to the control command. Exemplarily, as shown in table 1, the control instruction corresponding to the AP and the control instruction corresponding to the STA are identified.
TABLE 1
As can be seen from table 1, when the identifier of the control instruction received by the Wi-Fi Manager is identifier 01-identifier 05, it can be determined that the control instruction type is the control instruction corresponding to the STA. When the mark of the control instruction received by the Wi-Fi Manager is the mark 06-09, the control instruction type can be determined to be the control instruction corresponding to the AP.
S503: and calling a state machine to acquire a first state corresponding to the type of the control instruction by the Wi-Fi Manager based on the type of the control instruction.
And calling the state machine to acquire a first state of the terminal equipment at the previous moment corresponding to the control instruction type by the Wi-Fi Manager according to the control instruction type. The previous time refers to a time before the terminal device receives the control instruction, or may be understood as a current time when the terminal device does not execute the control instruction.
Illustratively, in the application scenario as shown in fig. 4, the terminal device 1 functions as both an STA (i.e., the network hotspot where the terminal device 1 is currently connected to the terminal device 2) and an AP (i.e., the network hotspot where the terminal device 3 is currently connected to the terminal device 1). If the type of the control instruction received by the Wi-Fi Manager is the control instruction corresponding to the STA, the Wi-Fi Manager calls a state machine to acquire a first state when the terminal device is used as the STA, and the first state is as follows: connect Wi-Fi state.
S504: and the Wi-Fi Manager calls the state machine to determine a second state corresponding to the control instruction based on the type of the control instruction and the control instruction.
And the Wi-Fi Manager calls the state machine to determine that the terminal equipment is in a second state of the type of the control instruction after the terminal equipment executes the control instruction according to the type of the control instruction and the control specification.
Illustratively, in the application scenario as shown in fig. 4, the terminal device 1 functions as both an STA (i.e., the network hotspot where the terminal device 1 is currently connected to the terminal device 2) and an AP (i.e., the network hotspot where the terminal device 3 is currently connected to the terminal device 1). If the control instruction received by the Wi-Fi Manager is an instruction for disconnecting the Wi-Fi network, and it can be seen that the type of the control instruction is a control instruction corresponding to the STA, the Wi-Fi Manager invokes a state machine to determine a second state corresponding to the control instruction, which can be understood that if the terminal device executes the control instruction, the second state of the terminal device as the STA is: the connected state is disconnected.
S505: and the Wi-Fi Manager calls a state machine to verify whether the control instruction is legal or not according to the first state and the second state.
And the Wi-Fi Manager verifies whether the control instruction is legal or not according to the first state, the second state and the logic sequence among the states.
It should be noted that, the logic sequence between the states may be understood that, after the terminal device executes the control instruction, the terminal device can switch from the first state to the second state, and then it is determined that the control instruction is legal. For example, when the first state of the terminal device is the STA mode on state, the terminal device may execute an instruction to scan the Wi-Fi network, and switch the STA mode state of the terminal device to the Wi-Fi scanning state. And when the first state of the terminal equipment is the Wi-Fi network connected state, executing an instruction of disconnecting the Wi-Fi network, and switching the STA mode of the terminal equipment to the network disconnection state. When the first state of the terminal device is the STA mode on state, the terminal device may execute an instruction to turn off the STA mode, and switch the STA mode state of the terminal device to the STA mode off state. When the first state of the terminal device is the AP mode on state, the terminal device can execute the instruction to turn off the AP mode, and the AP mode state of the terminal device is switched to the AP mode off state. When the first state of the terminal device is a hotspot opening state, the terminal device can execute a hotspot closing instruction, and the AP mode state of the terminal device is changed into a hotspot closing state.
Illustratively, when the type of the control command is a control command corresponding to the STA: and if the Wi-Fi network is disconnected, the second state corresponding to the control instruction is as follows: Wi-Fi network disconnect status. If the first state of the STA mode (that is, the terminal device is used as an STA) of the current terminal device obtained according to the type of the control instruction is: and if the Wi-Fi network is in the connected state, determining that the control command is: the "instruction to disconnect Wi-Fi network" is legitimate. If the first state obtained according to the type of the control instruction when the STA mode of the current terminal device (that is, the terminal device serves as the STA) is: and if the STA mode is in the off state, determining that the control command: the "instruction to disconnect Wi-Fi network" is illegal.
S506: and the Wi-Fi Driver drives the Wi-Fi Firmware to execute the corresponding operation of the control instruction according to the control instruction.
The specific implementation manner of step S506 may refer to the specific implementation manner of step S203 in the foregoing embodiment, and will not be described in detail herein.
In the embodiment of the present application, the terminal device determines the type of the control instruction according to the identifier of the control instruction, and then invokes the state machine to determine whether the control instruction is legal according to the type of the control instruction, so as to ensure that the terminal device executes the control instruction with legal operation logic, that is, as shown in fig. 4.
