UART Serial Port Rate
（
bps
）
For the two modules that communicate with each
other, the serial port baud rate can be different,
and the verification method can also be different;
When continuously transmitting large data
packets, users need to consider the data
congestion caused by the same baud rate, and may
even be lost;
It is generally recommended that the baud rate of
the two communication parties be the same.

Air Data Rate
（
bps
）
The air rate of both parties must be the same;
The higher the air rate, the smaller the delay and
the shorter the transmission distance.
