Looks like you're using the 5v version of the bme280, there's an extra 3.3v regulator on this board, this could be the culprit.

RE: SmartSleep wake up message always get NACK
@berkseo Hi, could you post the link to your pull request ? I don't see any traces of it in MySensors Github repository.
BTW with my setup (genuine/good quality NRF24L01) increase lines 67 & 114 of RF24.ccp to 50 do the trick.
