In sleep mode（M0=1，M1=1）,
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.

Remark
Must be 0xC0 or 0xC2
UART mode can be different between
communication parties
UART baud rate can be different
between communication parties
The UART baud rate has nothing to do
with wireless transmission parameters &
won't affect the wireless transmit /
receive features.
The lower the air data rate, the longer
the
transmitting
anti-interference performance and longer
transmitting time
The air data rate must keep the same for
both communication parties.
