for
distinguishing
networks. It
should be set to
the same when
communicating
with each other.
Two modules
communicating
with each other
can have different
serial port baud
rates. The
checksums can also
be different.
When transmitting
larger data
packets
continuously,
users need to
consider data
blocking and even
possible loss due
to the same baud
rate. It is
generally
recommended that
the baud rates of
both sides of the
communication are
the same.
Both sides of the
communication
must be the same.
The higher the
rate, the lower
the delay and the
shorter the
distance.
