E22-230T30D User Manual
Module address high byte and low byte;
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 perform address filtering at this time.
etwork address, used to distinguish the
network;
When communicating with each other, they
should be set to the same.
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 transmitting large data
packets, users need to consider the data
blocking caused by the same baud rate, and
may even be lost;
It is generally recommended that both sides
of the communication have the same baud
rate.
The serial port modes of both sides of the
communication can be different；
The air speed of both parties must be the
same;
The higher the air rate, the lower the delay
and the shorter the transmission distance.
When the data sent by the user is less than
the packet length, the serial output of the
receiving end is presented as uninterrupted
continuous output;
