Notes
Must be 0xC0 or 0xC2
C0: Save the parameters when power-down
C2: Do not save the parameters when power-down
00H-FFH
00H-FFH
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
distance,
better
performance and longer transmitting time
The air data rate must keep the same for both
communication parties.
Under continuous transmitting mode (M0=1 M1=0
M2=0), this parameter is invalid
anti-interference
