7 Enable RSSI bytes

When enabled, the module

receives wireless data, which will
follow an RSSI intensity byte when
output through the serial port TXD.

0 Disable (default)

1 start using

6 transmission method

The module will recognize the

first three bytes of the serial data as:
address high + address low +
channel, and use them as the wireless
transmit target.

0 Transparent transmission (default)

1 fixed-point transmission

5 relay function

When the relay function is

enabled, the module will initiate a
forwarding if the destination address
is not the module itself.

In order to prevent data

backhauling, it is recommended to
use it in conjunction with fixed-point
mode. That is, the destination address
is different from the source address.

0 Disable trunking (default)

1 Enable relay function

4 LBT Enable

When enabled, wireless data

will

be

listened

to

before

transmitting,

which

can

avoid

interference to a certain extent, but
may bring data delays

The LBT has a maximum dwell
