sides of the communication have the
same baud rate.
The serial port modes of both sides of the
communication can be different;
The air speed of both parties must be the
same;
The higher the air rate, the lower the
delay and the shorter the transmission
distance.
When the data sent by the user is less
than the packet length, the serial output
of the receiving end is presented as
uninterrupted continuous output;
If the data sent by the user is larger than
the packet length, the serial port of the
receiving end will be output in packets.
After it is enabled, the C0 C1 C2 C3
instruction can be
transmission mode or
transmission mode to read the register;
Register 0x00: Current ambient noise
RSSI;
Register 0X01: RSSI when data was last
received
(The current channel noise is: dBm
=-RSSI/2);
Instruction format: C0 C1 C2 C3 + start
address + read length;
Return: C1 + address address + read
length + read valid value; such as: send
C0 C1 C2 C3 00 01
return C1 00 01 RSSI
The relationship between power and
current is non-linear. At maximum
