⚫ The module address is high byte and low byte. Note:
When the module address is FFFF, it can be used as
the broadcast and monitor address, that is the module
will not perform address filtering.
⚫ 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
⚫ The higher the rate, the shorter the distance
