Hello, I'm an old programmer trying to use Arduino, then my experience has a lot of limits. I'm trying to establish communication between two Elegoo Uno R3 connected the first to the RF2401 module with antenna (client) and the other one with the second module of RF24L01 (server). I checked the connnection between Arduinos and RF24L01 modules and I think that they are correct.
I'm using the RadioHead NRF24 library. Both client an server are derived by the library examples.
The client, running on COM3, seems to run correctly: init OK, setChannel OK, setRf OK, error when it wait for server response
The server, running on COM5 port, fails when executes the init statement. I am also surprised that after init failure, setChannel and setRf return an ok status. In any case it receive nothing bay the client.
I read many post but my experience couldn't make me able to find out the solution. Can anyone help me? Thanks in advance
