UART serial port rate
(bps)
Two modules communicating
with each other can have different
serial port baud rates. The checksum
method can also be different.
When transmitting larger
packets continuously, users need to
consider the data blocking and even
possible loss caused by the same
baud
rate. It is generally
recommended that both sides of the
communication have the same baud
rate.
