TTL UART baud rate
（
bps
）
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.

Air data rate
（
bps
）
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.

Fixed transmission (similar to MODBUS
）
When it is 1, the first three bytes of each
user data frame can be used as high/low
address and channel. The module changes
its address and channel when transmitting.
And it will revert to original setting after
the process is completed.
It is transparent transmission under
continuous mode.
