High byte and low byte of module address;
Note: When the module address is equal to FFFF,
it can be used as the broadcast and monitor
address, that is: the module will not perform
address filtering at this time
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
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.
The serial port mode of the communication parties
can be different;
The air rate of both parties must be the same;
The higher the air rate, the smaller the delay and
the shorter the transmission distance.
