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 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.

Both parties must be the same
