7.2 E22-400/900T30D, E22-400/900T30S register description
High byte and low byte in the module address;
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.
Network address, used to distinguish the network.
When two or more modules need to communicate
with each other, their network address should be
the same.
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.
Serial port baud rate 1200
Serial port baud rate 2400
Serial port baud rate 4800
Serial port baud rate 9600
（default）
Serial port baud rate 19200
Serial port baud rate 38400
Serial port baud rate 57600
Serial port baud rate 115200
The communication parties can have different
serial parity bit.
Wireless air data rate（bps）
The communication parties must have the same
air data rate.
The higher the air data rate is, the smaller the
delay in response, and the shorter the transmission
distance is.
Air data rate 2.4k
（
default
）
When the data sent is smaller than the sub packet
length, the serial output of the receiving end is an
uninterrupted continuous output.
