3. ATAT command instructions
Command format: In the AT command mode, the system can be configured through the AT
command of the serial port. The command format is as follows:
at+[command]=[value],[value],[value]......
All commands start with "at" and end with "\r". If the command is not encapsulated in this
format, it will not be processed, and the module will return different return values according to
different commands.
For example: "at+ver=?"
The module will return: HLK-B36 (b.1.00.120191206180224)
Query command format:
at+[command]=?
