Detailed Description

The invention will be further illustrated with reference to specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.

Referring to fig. 1, the invention discloses a wireless debugging system for intelligent devices, which includes a wireless debugging tool 2 composed of an ESP-writer-KITV 2 development board, a wireless router 3, a plurality of intelligent devices 1 to be debugged, and an SD card.

In the SD card interface 5 of the intelligent wireless device debugging system of this embodiment, an SD card is inserted, and a display screen 4 is also provided, so based on this embodiment, the debugging method using the intelligent wireless device debugging system includes the steps of:

The principle of the screening is to select the intelligent device 1 to be debugged according to Wi-Fi signal strength (low signal-to-noise ratio caused by weak signal strength can affect debugging efficiency) or equipment manufacturer (MAC address) of the intelligent device 1, and establish hardware connection.

Step 3, the wireless debugging tool 2 configures the intelligent devices 1 to be debugged one by one, and establishes software connection between the debugging service module and each debugging client module; in this step, the wireless debugging tool 2 sends configuration information to each of the intelligent devices 1 to be debugged one by one.

After the configuration is completed, each intelligent device 1 to be debugged returns the state of whether the configuration is successful to the wireless debugging tool 2, and under the condition of successful configuration, the MAC address of the wireless debugging tool 2 is recorded, so that when the intelligent device 1 is abnormal, the intelligent device is capable of and will actively send abnormal information to the wireless debugging tool 2.

Step 4, the debugging service module sends a debugging command to the debugging client module; the debugging client module executes the debugging command and returns a result to the debugging service module. For example, a firmware version of the intelligent device 1 may be acquired through a command, or the intelligent device 1 may be restarted, or log information generated by the intelligent device 1 in a previous operation may be acquired through a log command.

Step 5, the debugging service module inquires the state of the intelligent equipment 1 from the debugging client module; the debugging client module returns the state of the intelligent device to the debugging service module, and the wireless debugging module displays the state of the intelligent device 1 on the LCD after analyzing the result.

8.2, the debugging client module inquires the core dump of the intelligent device 1 and returns a core dump result to the debugging service module; and if the current equipment does not have the core dump, returning a result to the debugging service module to inform the debugging service module that the core dump does not exist currently.

Step 8.3, if the debugging client module returns the core memory, the debugging service module stores the core dump result into the SD card;
