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

The air rate of both communication parties must
be the same;
The higher the air rate, the smaller the delay and
the shorter the transmission distance.
