Data transmission problem

[giubu]

Hi there, I don't know if this is still active, but I'll give it a go anyway...
I am trying to setup two arduino pro micro as transmitter and receiver for an RC car.
when I upload your code, Transmitter reports on monitor that packages are sent, but receiver only reports zeros.
is there a way to check what is going on?

Hello! I apologize but I have not worked on this in many years. However I wonder if everything is wired properly? What happens if you flash the transmitter as a receiver and receiver as a transmitter?
