PeterH:
This code is designed for use in a non-blocking sketch. The sketch would execute this code at regular intervals and handle radio messages as they arrive. You would need to design the rest of your sketch to be non-blocking too, so that it can execute this code periodically.
Thanks for the prompt reply PeterH
So are you saying that the normal loop would bypass the rf code, until the loop detects incoming data ? And at that point, it would execute the rf section of code and when that is completed, would then continue with the rest of the sketch ?
