remarks
Module address of high and low bytes;
Note: When the module address is equal to FFFF,
it can be used as a broadcast and listening address,
that is, the module will not filter the address
Network address, used to distinguish networks;
When communicating with each other, set it as the
same.
The two modules of mutual communication, the
serial port port rate can be different, the
calibration mode can also be different;
When large data packets
continuously, users need to consider the data
blocking caused by the same port rate, or may
even be lost;
It is generally recommended that the same have
the same the same.
The communication two sides serial port mode
can be different;
