Note: When the module address is FFFF, it can be
used as the broadcast and listening address, that
is: the module will not perform address filtering.

UART Serial port rate
(
bps
)
For the two modules communicating with each
other, their serial port baud rate can be different,
and their serial parity bit can also be different.
When transmitting large packets continuously,
users need to consider the data blocking and
possible data loss caused by the same baud rate.
It is generally recommended that both
communication parties have the same baud rate.
