Wow, I think it may be time to go back to Arduino. This could not be any more complicated if you tried! The documents appear to be outdated. The information that I can find about loading libraries doesnt look anything like what I see. It looks like there used to be a way to upload a library in the old IDE but not any more. I cannot even locate in the Particle Dev where or how to upload the RadioHead library for starters.
Just so I understand, the thread you sent me to is for the LoRa radio you are using so therefore it does not apply to the nRF24L01?
I appreciate your help and guidence. Time for a break. I have spent the better part of a day to get a headache!
