RSSI));
Instruction format: C0 C1 C2 C3+start
address+read length;
Return: C1 + address + read length + read
valid value; such as: send C0 C1 C2 C3 00

Return C1 00 01 RSSI (address can only start
from 00)
Power and current have a non-linear
relationship, and the power supply
efficiency is the highest at the maximum
power;
The current does not decrease
proportionally as the power decreases.
Actual frequency = 220.125 + CH * 0.25M
When enabled, the module receives wireless
data and outputs it through the serial port
TXD, followed by an RSSI strength byte.
For fixed-point transmission, the module
identifies the money three bytes of the
serial data as: address high + address low
+ channel, and uses them as the wireless
transmitting target.
(a) When the relay function is enabled, the
module will initiate a forwarding if the
destination address is not the module
itself;
To prevent data backhaul, it is recommended
to use with fixed-point mode; i.e., 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
may cause data delay;
The maximum stay time of LBT is 2 seconds.
When it reaches two seconds, it will be
issued forcibly.
Valid only for mode 1;
1. wor's receive mode, the module can modify
the delay time after wake-up, the default
time is 0;
2. the receiver needs to send the command
C0 09 02 03 E8 in configuration mode (C0 is
the write command, 09 is the host initiator
address, 02 is the length, 03 E8 is the set
delay time, the maximum FFFF that is
65535ms, set to 0 to turn off the wake-up
