@gregl Thank you for your guide how to do the hardware changes. I'm more of a software guy, so I would like to try that route. You mentioned the software changes to the RF24 library in the wiki, but where should I change this library? I'm would like to use the EthernetGateway.ino on the iBoard, but I'm missing something and I can't figure out what it is. Just started with MySensors.

I hope you can give me some pointers.
Thanks a lot!
