,
User gives the module instruction (HEX format): C4 C4 C4, the module resets for one time. During
the reset process, the module will conduct self-check, AUX outputs low level. After reset completing,
the AUX outputs high level, then the module starts to work regularly which the working mode can be
switched or be given another instruction.

UART baud rate can be different between
communication parties
The UART baud rate has nothing to do with

Air data rate
（
bps
）
The lower the air data rate, the longer the
transmitting distance, better anti-interference
performance and longer transmitting time
The air data rate must keep the same for
both communication parties.
