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.
