Enable RSSI bytes
When enabled, the module receives wireless data,
which will follow an RSSI intensity byte when
output through the serial port TXD.

Transmission method
For fixed-point transmission, the module
identifies the first three bytes of the serial data as:
address high + address low + channel, and uses
them as the wireless transmitting target.
0
Transparent transmission (default)
1
Fixed-point transmission
5
Relay function
(a) When the relay function is enabled, the
module will initiate a forwarding if the destination
address is not the module itself.
To prevent data backhaul, it is recommended to
use with fixed-point mode; i.e., the destination
and source addresses are different.

4
LBT enable
When enabled, wireless data is listened to before
it is transmitted, which can avoid interference to
some extent, but may introduce data delays.
The maximum dwell time of LBT is 2 seconds,
and it will be forced to issue when it reaches two
seconds.

WOR mode transceiver control
Valid only for mode 1.
1. wor's receive mode, the module can modify the
delay time after waking up, the default time is 0.
2. The receiver needs to send the command C0 09
02 03 E8 in configuration mode (C0 is the write
command, 09 is the host initiator address, 02 is
the length, 03 E8 is the set delay time, the
maximum FFFF that is 65535ms, set to 0 to turn
off the wake-up delay).
3. Data can be sent within the delay time
0
WOR recipient (default)
Working in WOR listening mode, see below for
the listening period (WOR cycle), can save a lot
of power consumption.
1
WOR launcher
The module sends and receives on and adds a
wake-up code for a certain time when
transmitting data.

WOR Cycle
Valid only for mode 1.
Cycle time T= (1+WOR)*500ms, maximum
4000ms, minimum 500ms.
The longer the WOR listening interval cycle time,
the lower the average power consumption, but the
greater the data latency.
Both sending and receiving parties must agree
(very important)
