⚫ 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.
⚫ Network address, used to distinguish the network.
When communicating with each other, they
should be set to the same.
7，6，5 UART: Serial port rate（bps）
000: 1200
001: 2400
010: 4800
011: 9600（default）
100: 19200

110: 57600
111: 115200
---------------------------------------
4，3： Serial parity bit
00：8N1（default）
01：8O1
10：8E1

⚫ 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
7，6： Sub packet setting
00: 240 bytes（default）
01: 128 bytes
10: 64 bytes
11: 32 bytes
--------------------------------------
5 ：RSSI Ambient noise enable
1: Enable
0: Disable（default）
--------------------------------------
4，3，2 Reserve
--------------------------------------
1，0： Transmitting power
⚫ When the data is smaller than the sub packet
length, the serial output of the receiving end is an
uninterrupted continuous output.
When the data is larger than the sub packet
length, the receiving end serial port will output
the sub packet.
--------------------------------------------
⚫ When enabled, the C0 C1 C2 C3 command can
be sent in the transmitting mode or WOR
