Team,
I can get the atmega into sleep, recovering from idle sleep also works, but I need to spend a little more time to recover from power down 
Also having sleep as the 4th mode is not that convenient as its unclear whether the bee should bee in transmit/receive/transceive mode after wakeup…
I’ll give it a try to sort it out and to also include the WOR stuff, might take some time though
Cheers,
Hans
