WOR transmitter
The
module
receiving
and
transmitting functions are turned on, and a
wake-up code is added when transmitting data.
Receiving is turned on.

WOR receiver
（

The module is unable to transmit data
and works in WOR monitoring mode. The
monitoring period is as follows (WOR cycle),
which can save a lot of power.

When enabled, the module receives wireless data
and it will follow an RSSI strength byte after output
via the serial port TXD
.---------------------------------------
The module recognizes the first three bytes of the
serial data as: address high + address low + channel
and takes it as the wireless transmitting target.
---------------------------------------
After the reply function is enabled, if the target
address is not the module itself, the module will
forward it once.
In order to prevent data return-back, it is
recommended to use it in conjunction with the fixed
point mode. That is: the target address is different
from the source address.
----------------------------------------
When enabled, wireless data will be monitored
before it is transmitted, which can avoid interference
to a certain extent, but may cause data delay.
----------------------------------------
Valid only for mode 1.
After the WOR receiver receives the wireless data
and outputs it through the serial port, it will wait for
1000ms before entering the WOR again. Users can
input the serial port data and return it via the wireless
during this period. Each serial byte will be refreshed
for 1000ms. Users must transmit the first byte within
1000ms.
---------------------------------------------
Valid only for mode 1.
Period T = (1 + WOR) * 500ms, maximum 4000ms,
minimum 500ms
The longer the WOR monitoring interval period, the
lower the average power consumption, but the
greater the data delay
Both the transmitter and the receiver must be the
same (very important).

Used for user encryption to avoid intercepting
airborne wireless data by similar modules.
The module will internally use these two bytes as a
calculation factor to transform and encrypt the
over-the-air wireless signal.
