The JN-Micro does not receive native packets either. - End of ideas for the time being. Rolf

I think it is me that is confused. I have mixed two different forum topics. JohnO
19:38 Support: RE: Jeenode Micro in RF12_COMPAT mode?
Incidentally your latest code doesn't have RF12_COMPAT or RF69_COMPAT. JohnO

Ah, I see you do rf12_initialize twice, once in setup() and again in loop(). JohnO

I would add a 1000ms delay after powering up the radio before calling the rf12_initialize. JohnO
