when transmitting data, a wake-up code for
a certain period of time is added.
WOR transmitter
The radio cannot transmit data and works
in WOR monitoring mode. The monitoring
1
period is shown below (WOR period),
which can save a lot of power
consumption.

The relationship between power and
current is non-linear. At the maximum
power, the power supply has the highest
efficiency; the current will not decrease
in the same proportion as the power
decreases.
Actual frequency = 410.125 + CH *1M
After being enabled, the radio receives
wireless data and outputs it through the
serial port TXD, followed by an RSSI
strength byte.
During fixed-point transmission, the
radio will recognize the three bytes of
serial data as: address high + address low
+ channel, and use it as a wireless
transmission target.
After the relay function is enabled, if the
target address is not the radio station
itself, the radio station will start a
forwarding;
In order to prevent data return, it is
recommended to use it in conjunction
with the fixed-point mode; that is, the
destination address and the source
address are different.
After enabling, the wireless data will be
monitored before transmission, which
can avoid interference to a certain extent,
but it may cause data delay;
The maximum stay time of LBT is 2
seconds, and it will be issued forcibly
when it reaches 2 seconds.
Only valid for mode 1;
After the WOR receiver receives the
wireless data and outputs it through the
serial port, it will wait 1000ms before
entering the WOR again. During this
period, the user can input the serial data
and return it wirelessly;
Each serial port byte will be refreshed for
1000ms;
The user must initiate the first byte
within 1000ms.
Only valid for mode 1;
