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

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
anti-interference performance and longer
transmitting time
The air data rate must keep the same for
both communication parties.
