
Power and current are nonlinear,
and power efficiency is highest at
maximum power.

The current does not decrease in
proportion to the decrease in
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.
-------------------------------------

Only valid in 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.
