Hello. I've bought two RF modules, a transmitter and a receiver, both at 315 MHz to make 2 microcontrollers talk to each other.
But i have problem making them talk using their serial ports. So i wonder:
Before doing anything else is there a simple way, i.e. a simple circuit to try, that i can be sure that they work properly?
Because it's a loss of time trying to make something work if it has a hardware problem.
Thanks!
