7.4. Reset Command
Command Format Description
C4+C4+C4
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.
7.5. Parameter Configuration Commands
No. Item Description Remarks
0 HEAD Fix 0xC0 or 0xC2, it means this frame data is control command
Must be 0xC0 or 0xC2
C0: Save the parameters when power-down
C2: Do not save the parameters when
power-down

Under continuous transmission mode, the
baud rate must be the same.

2 1 0 Air data rate (bps)
Under non-continuous transmission mode,
baud rate has nothing to do with RF
parameters, and will not affect the
transmission characteristics.
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, the better
anti-interference performance and the
longer transmitting time.
The air data rates on both sides must be the
same.
