Communication module, such as any one of 2G communication module, 3G communication module, 4G communication module, 5G communication module, NB-IOT communication module, etc.

An embodiment of the present application provides a method for restoring a function of a wireless communication module, and the method can be applied to any form of electronic equipment, such as a wireless communication module. As shown in Figure 2, the function recovery method of the function module includes:

Step 201: When it is determined that the wireless communication module enters the recovery mode, a target transmission interface for communicating with the host is determined from a preset transmission interface cluster of the wireless communication module, and the preset transmission interface cluster includes at least two transport interface.

In some embodiments, a preset transmission interface cluster is set on the wireless communication module, and the preset transmission interface cluster includes at least two transmission interfaces. When the wireless communication module is in use, any transmission interface of the wireless communication module can be correspondingly connected with the transmission interface of the host used by the wireless communication module, so as to perform data transmission through the connected transmission interface. It can be understood that, on the host used by the wireless communication module, a plurality of transmission interfaces can also be set to connect the wireless communication module with the same interface on the host correspondingly.

Specifically, after the wireless communication module is connected to the host and powered on, if the Bootloader determines that the wireless communication module enters the recovery mode, it first determines the target transmission interface for communication with the host from the preset transmission interface cluster of the wireless communication module.

The wireless communication module may be a product with a bootloader capable of realizing certain functions. For example, the wireless communication module may be, but not limited to, a wireless communication module.

The interface types of the transmission interfaces included in the preset transmission interface cluster may be, but not limited to, a Universal Serial Bus (USB) interface, a Serial Peripheral Interface (SPI) interface, and a Universal Asynchronous Receiver Transmitter (UART) interface. and Ethernet (ETH) interface.

Further, the interface type of the transmission interface in the preset transmission interface cluster may be at least one of the above-mentioned interface types, that is, the at least two transmission interfaces may be the same interface type or different interface types. can be selected according to the actual situation.

Further, in addition to setting the transmission interface on the wireless communication module, the driver of each transmission interface in the preset transmission interface cluster will also be integrated in the startup guide program of the wireless communication module, so that the target transmission interface is used to perform the process. During data transmission, the driver of the target transmission interface can be called, and the function of the target transmission interface can be realized based on the driver.

There are various ways to determine that the wireless communication module enters the recovery mode. In an optional embodiment, determining that the wireless communication module enters the recovery mode includes:

When the boot program fails to start the advanced operating system in the wireless communication module, it is determined that the wireless communication module enters the recovery mode.

In some embodiments, after the wireless communication module is turned on, the Bootloader in the wireless communication module is started first, and after the startup, the advanced operating system in the wireless communication module is loaded. If the advanced operating system is successfully started, the wireless communication module The group enters the normal function state to achieve normal functions; if the advanced operating system fails to start, it is determined that the wireless communication module is in recovery mode, and the firmware image file needs to be re-obtained for upgrade and repair.

In an optional embodiment, determining the target transmission interface for communication with the host in the preset transmission interface cluster of the wireless communication module includes:

Detecting whether the transmission interface in the preset transmission interface cluster has received the request sent by the host; and determining that the transmission interface that has received the request sent by the host is the target transmission interface.

In some embodiments, after the wireless communication module enters the recovery mode, the Bootloader will detect whether the transmission interface in the preset transmission interface cluster has received the request sent by the host. The transmission interface establishes a communication connection with the host, so that the transmission interface that receives the request is used as the target transmission interface.

Among them, there are many ways for the Bootloader to detect whether the transmission interface receives the request sent by the host, and the following two real-time ways are used as examples to illustrate. It can be understood that, in the actual implementation process, it is not limited to the following two ways.

In an optional embodiment, the detecting whether the transmission interface in the preset transmission interface cluster receives the request sent by the host includes:

According to the detection period of each transmission interface in the preset transmission interface cluster, in each detection period, it is detected whether the transmission interface receives the request sent by the host.

In some embodiments, a detection period may be set for each transmission interface, and for the detection of the transmission interface, whether the transmission interface receives a request sent by the host may be detected once per detection period.

It can be understood that the detection period for each transmission interface may be the same or different. If the detection period of each transmission interface is different, the detection can be performed according to its own detection period; if the detection period of each transmission interface is the same, each transmission interface can be detected in sequence within the same detection period.

Exemplarily, taking the number of transmission interfaces as two as an example, the detection period of the first transmission interface may be set to be detected once in 0.02 microseconds, and the detection period of the first transmission interface may be set to be detected once in 0.03 microseconds.

In an optional embodiment, the detecting whether the transmission interface in the preset transmission interface cluster receives the request sent by the host includes:

At every preset time interval, it is sequentially detected whether the transmission interfaces in the preset transmission interface cluster receive the request sent by the host.

In some embodiments, the detection order of the transmission interfaces can be set according to actual needs, or when the detection order is not preset, during the first detection, one of the transmission interfaces in the preset transmission interface cluster can be randomly selected for the detection. Detection, until each transmission interface in the preset transmission interface cluster has been detected once, if the target transmission interface is not detected, according to the sequence of the first detection, every preset time interval, the preset transmission interface cluster is detected. The transmission interface performs subsequent detection.

Wherein, the preset duration may be set according to the actual situation, which is not limited here. For example, the preset duration may be 0.01 to 0.03 microseconds.

Step 202: Acquire a firmware image file sent by the host based on the target transmission interface.

In some embodiments, after determining the target transmission interface, the host sends the firmware image file to the wireless communication module through the target transmission interface, so that the wireless communication module obtains the firmware image file sent by the host through the target transmission interface.

The host stores corresponding firmware, and when the wireless communication module enters the recovery mode, the host can copy the firmware to obtain a firmware image file and send it to the wireless communication module.

The firmware in the host may be obtained from the cloud, or it may be configured by the developer after the host is developed.

Step 203: Load the firmware image file into the wireless communication module, so as to restore the normal function of the wireless communication module.

In some embodiments, after obtaining the firmware image file, the Bootloader can store the firmware image file in the corresponding area of the wireless communication module, so that the firmware image file is activated by the Bootloader to realize the restart of the wireless communication module, thereby enabling the The wireless communication module returns to normal function.

Wherein, the above-mentioned restoration of normal function means that the wireless communication module can operate according to the program internally configured.

In an optional embodiment, after the firmware image file is loaded into the wireless communication module, the method further includes:

The wireless communication module is restarted based on the firmware image file to restore the normal function of the wireless communication module.

In some embodiments, the execution program of the above-mentioned advanced operating system is stored in the firmware image file. Therefore, after the firmware image file is loaded into the wireless communication module, the Bootloader restarts and starts the advanced operating system in the firmware image file. If the advanced operating system is successfully started, the wireless communication module can resume normal functions.

In a specific embodiment, referring to FIG. 3 , the method for restoring the function of a wireless communication module in this application can be applied to a product that supports multiple hardware transmission interfaces integrated. Among them, the integrated transmission interface in this product includes USB hardware interface, SPI hardware interface, UART hardware interface and ETH hardware interface. A new function is added to the Bootloader of this product, and the multiple hardware transmission interface driver codes that need to be supported are integrated into the Bootloader, thereby realizing the function of "download adapter" in the Bootloader. Specifically, the method includes:

First, regularly detect the USB hardware interface, if the host can receive a request to download the firmware image, select this hardware interface to implement the download process;

Second, regularly detect the SPI hardware interface, if the host can receive a request to download the firmware image, select this hardware interface to implement the download process;

Third, regularly detect the UART hardware interface, if the host can receive a request to download the firmware image, select this hardware interface to implement the download process;

Fourth, regularly detect the ETH hardware interface, if the host can receive a request to download the firmware image, select this hardware interface to implement the download process;

Fifth, regularly detect other hardware interfaces that need to be supported. If the host can receive a request to download a firmware image, select this hardware interface to implement the download process.

Sixth, after the Bootloader enters the recovery mode, use the hardware interface detected by the "download adapter" to complete the "redownload, upgrade, repair" process of the firmware.

The function recovery method of the present application can make the product in the recovery mode no longer limited by a single hardware transmission interface, and allow the Bootloader to flexibly adapt to a variety of hardware transmission interfaces in the recovery mode, which can greatly enhance the reliability of the product. The flexibility enables the same product to meet the hardware integration design requirements of different manufacturers.
