Sending and receiving data between two evaluation boards with the GHz Radio

I'm sorry for the late answer, but if you're looking for simple two-way communication between two boards, I'd strongly recommend you to look into Gazell. There are examples available in the SDK in the gzll sub-folder, and a documentation page that explains a little about the protocol and how it works here.

Yes, I understand this, but the code doesn't explain an easy way to do this. I need one radio to wait for a message, and when it receives the message, to send a reply package in response.

I need the other radio to send a message until it knows it's sent, then wait for the reply message. There are no examples of how to do this. I've tried just alternating the radio mode in the while loop, but then the radios neither send nor receive.

Is there any documentation on this?

The radio is not able to be a transmitter or a receiver at the same time. When one board is sending the other board needs to listen and vice versa.

To switch the state of the radio, you need to disable the radio and start it again in the new mode.
