The new library can be found here at github and enables communication to/from NRF24l01+ devices using the RF24 API, it can also be used of course for NRF52 to NRF52 communication.
I was sent a new XIAO BLE Sense device by https://www.seeedstudio.com/ so decided I would figure out how to manage communication. It was quite a project, since the Enhanced ShockBurst protocol has to be implemented in software. I have a few things to figure out, but the library is mostly functional, I'm looking for input on issues etc. and or improvements to make. It has been tested with the complete RF24 communication stack, although the RF24Network and higher libs need modifications to work with this library.
If anybody wants to try it out, please log any issues on GitHub.
