period is shown below (WOR period), which
can save a lot of power consumption.

In order to prevent data from being transmitted
back, it is recommended to use it in conjunction
with fixed-point mode ; that is, the destination
address and source address are different.
When enabled, wireless data will be monitored
before transmission, which can avoid interference
to a certain extent, but may cause data delays;
The maximum dwell time of LBT is 2 seconds.
The wireless data will be transmitted forcibly after
2 seconds.
Below operation is valid for Mode 1 only；
In WOR receiving mode (as WOR receiver), the
delay time after wake-up can be modified. The
default time is 0;
1. To modify the delay time after wake-up, WOR
receiver needs to send the command C0 09 02 03
E8 in the configuration mode (C0 is writing
command, 09 is the starting address of the
and
transmitting
register, 02 is the length, 03 E8 is the set delay,
the maximum delay FFFF is 65535ms, if the delay
is set to 0, the wake-up delay is turn off.)
2. Data can be sent within the delay.
Below description is valid for Mode 1 only；
Cycle time T = (1 + WOR) * 500ms,
max.4000ms, min.500ms;
The longer the cycle time T (WOR listening
interval period), the lower the average power
consumption, but the greater the data delay.
Both the transmitter and the receiver must be set
as the same cycle time T (very important).
Write only, read returns 0;
Used for encryption to avoid interception of
wireless data in the air by similar modules;
The module will internally use these two bytes as
a calculation factor to do a transform encryption
processing for the wireless signal over the air.
