Under configuration mode (M0=0, M1=1, M2 =0), send command (HEX format) to the serial: C4 C4 C4, the module
will conduct a reset;
During reset, the module will conduct self-check, AUX outputs low level, when reset is completed, AUX outputs high
level, the module starts to work normally. Now, user could switch mode or send another command.
Description
Fix 0xC0 or 0xC2, it means this frame data is control command
High address byte of module
（the default 00H）
Low address byte of module
（the default 00H）

The serial modes can be different on two
sides;
Under normal mode, the mode can be
different；
Under continuous transmission mode, the
baud rate must be the same.
Under non-continuous transmission mode,
baud rate has nothing to do with RF
parameters,

Under continuous transmission mode, baud
rate decides the air data rate. The high the
baud rate, the faster the data transmission
and the shorter communication range.
The lower the air data rate, the longer the
transmitting
distance,

longer transmitting time.
The air data rates on both sides must be the
