Hi Gabriele, if there is no output, chances are the receiver side packet detector doesn't see any valid packets. Make sure tx and rx parameters match, and adjust the RX gain. Make sure no under/overflows happen. There's quite a lot of things that can go wrong in a real-world transceiver, but these are the most likely to happen in my experience.
