Instruction format: in AT instruction mode, the system can be configured through the AT
instructions of the serial port. The command format is as follows:
at+[command]=[value],[value],[value]......
All commands begin with "at" and "\ r" end. If the command is not encapsulated in this format,
it will not be processed and will return a different return value depending on the command module.
For example:“at+ver=?”
Module will return: HLK-B32 (V1.00 (Nov 30 2017)
Query instruction format: at+[command]=?
