the subcontract length, and the serial
port output of the receiving end is
presented as uninterrupted continuous
output;
If the data sent by the user is greater
than the subcontract length, the serial
port of the receiving end will
subcontract the output.
The RSSI ambient noise is enabled
When enabled, instruction C0 C1 C2 C3 can
read register in transmission mode or WOR
transmission mode;
Register 0x00: current ambient noise
RSSI;
Register 0X01: RSSI last received
(The current channel noise is: dBm = -
(256-RSSI));
Instruction format: C0 C1 C2 C3 +
starting address + read length;
Return: C1 + address + read length + read
valid value;
Like: send a C0 C1 C2 C3 00 01
Return to C1 00 01 RSSI (address only
starts from 00)
Power and current are nonlinear
relationship, when the maximum power,
the power supply efficiency is the
highest;
The current does not decrease in equal
proportion with the power decrease.
Channel Control (CH)
0 – 64 represent a total of 65 channels,
respectively
Actual frequency = 220.125 + CH * 0.25M
When enabled, the module receives
wireless data and the output through the
serial port TXD will follow an RSSI
strength byte.
During the fixed point transmission, the
module will identify the three bytes of
the serial port data as: address high +
address low + channel, and take it as the
wireless transmission target.
Transparent transfer (by default)
After the relay function is enabled, if
the target address is not the module
itself, the module will start a forward;
To prevent data return, it is recommended
to work with fixed point mode; namely,
target address and source address are
different.
Disable Relay function (default)
