Module
address
Input, range
0-65535 (default
0)
Address of the module
Note: When the module address is equal to FFFF, it can be used as a
broadcast and monitoring address, that is, the module will not perform
address filtering at this time.
10 Parity
8N1 (default)
DTU serial parity check
8O1
8E1
11
WOR cycle
500 ms
The longer the WOR monitoring interval cycle time, the lower the
average power consumption, but the greater the data delay;
1000 ms
1500 ms
2000 ms (default)
2500 ms
3000 ms
3500 ms

LBT enabled
Off (default)
turn on
After enabling, wireless data will be monitored before transmission,
which can avoid interference to some extent, but may cause data delay;
13
Frequency
channel
Input, range 0-83
(default 23)
The maximum lingering time of LBT is 2 seconds, and it will be issued
when it reaches 2 seconds.
14
Air speed
0.3 Kbps
The air speed of both communication parties must be the same;
The higher the air speed, the smaller the delay and the shorter the
transmission distance.
1.2 Kbps
2.4 Kbps (default)
4.8 Kbps
9.6 Kbps
19.2 Kbps
38.4 Kbps
62.5 Kbps

Module
power
Off (default)
Module transmit power
Power and current are non-linear, and the power supply has the highest
efficiency at maximum power;
The current does not decrease in proportion to the decrease in power.
turn on
Input, range 0-83
(default 23)
0.3 Kbps
16
Data RSSI
1.2 Kbps
2.4 Kbps (default)
After being enabled, the module will receive the wireless data and output
through the serial port TXD, followed by an RSSI strength byte.
17 Network ID Off (default)
Network address, used to distinguish the network;
When communicating with each other, they should be set to the same.
18
Sub-contract
length
turn on
The data sent by the user is less than the length of the sub-packet, and the
serial port output of the receiving end appears as an uninterrupted
continuous output;
The data sent by the user is longer than the packet length, and the serial
Input, range 0-83
(default 23)
