The maximum lingering time of LBT is 2
seconds, and it will be sent when it reaches 2
seconds.
Valid only for mode 1.
1. In the receiving mode of WOR, the module can
modify the delay time after wake-up.Default time
is 0;
2. The receiving end needs to send the command
C0 09 02 03 E8 in configuration mode (C0 is the
write command, 09 is the register initiator
address, 02 is the length, 03 E8 is the set delay,
the maximum FFFF is 65535ms, set to 0 turns off
the wake-up delay);
3. Data can be sent within the delay.
WOR receiver
（
default
）
The module works in WOR monitoring mode.
The monitoring period is as follows (WOR
cycle), which can save a lot of power.
WOR transmitter
The module receiving and transmitting
functions are turned on, and a wake-up code is
added when transmitting data.
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).
Key high byte (default 0）
Write only, read returns 0
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.
