Hey i am working on the HC-12 wireless communication module for a quite while now. I am having a few doubts about it.
I don't understand what channel if properly. Like will the information be transmitter in different frequencies ? what is its advantage ? why cant we just use one channel? how helpful is it in tacking some problems?
Doubt 2 about eh HC-12
To enter the setup mode i give digital low to the set pin. So to exit the setup mode should i give a digital high command? if not how to exit it using the program
Do the "AT" commands not work for you?

It works, but i dont understand like for what can i use it and how.
I have done a program now which can tranmitt about 5 variables at a time.
If necessary i can change the baud rate according to the distance.
So what will i use the different channels for?
The different channels are so you can pick one that has the least interference from noise and other devices.

I live on a 12 acre property. I am building a perimeter monitor, essentially a burglar alarm. I need about 14 sensors. the channels need to be spaced 5 channels apart, and suddenly there are not too many channels
