7 6 5 UART Serial Port Rate
（
bps
）
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
congestion caused by the same baud rate, and may
even be lost;
It is generally recommended that the baud rate of
the two communication parties be the same.
0 0 0 UART Rate is 1200
0 0 1 UART Rate is 2400
0 1 0 UART Rate is 4800
0 1 1 UART Rate is 9600
（

）
1 0 0 UART Rate is 19200
1 0 1 UART Rate is 38400
1 1 0 UART Rate is 57600
1 1 1 UART Rate is 115200
4 3 Serial Parity Bit
The serial port mode of the communication parties
can be different;

0 1 8O1
1 0 8E1
1 1 8N1

2 1 0 Air Data Rate
（
bps
）
The air rate of both parties must be the same;
The higher the air rate, the smaller the delay and
the shorter the transmission distance.
0 0 0 Air Data Rate 2.4k
0 0 1 Air Data Rate 2.4k
0 1 0 Air Data Rate 2.4k

0 1 1 Air Data Rate 4.8k
1 0 0 Air Data Rate 9.6k
1 0 1 Air Data Rate 19.2k
1 1 0 Air Data Rate 38.4k
1 1 1 Air Data Rate 62.5k

7 6 Sub-Packet Setting
The data sent by the user is less than the
sub-packet length, and the serial port output of the
receiving end appears as an uninterrupted
continuous output;
The data sent by the user is larger than the packet
length, and the serial port of the receiving end will
be output in packets.

5 RSSI Ambient noise enable
After enabling, you can send commands C0 C1
C2 C3 in transmission mode or WOR sending
mode to read registers;
Register 0x00: Current environmental noise RSSI;
Register 0X01: RSSI when receiving data last
time
(The current channel noise is: dBm = -
（
256 -
RSSI
）
);
Instruction format: C0 C1 C2 C3+start
read length;
Return: C1 + a read read valid
value; for example: send C0 C1 C2 C3 00 01
Return C1 00 01 RSSI (address can only start
from 00)
