@alterfritz thanks. Now we know where in the code the crash occurs. Hopefully @marceloaqno can figure out what's wrong. I'll take a look as well, but I am not familiar with that code so I am not sure I will understand it.

[alterfritz]

Thanks a lot. Looking forward to any update... have a nice weekend, I will try the version for ESP8266 in the meantime, however run it on the pi would be preferred.

Thanks again!

[alterfritz]

Just to let you know - I have uploaded the ESP8266 sketch (from 2.1.1) via Arduino IDE, seems to run stable with the same NRF24L01 module.

But if possible I would like to go back to have all run on the raspi.

Again thanks for all that support here!

[tekka]

@alterfritz I've prepared a PR that should fix the segmentation fault: https://github.com/tekka007/MySensors/tree/nullptr - can you test this PR?

[alterfritz]

Many thanks - yes, will do today. Let you know results.

[alterfritz]

Seems this does the trick. Thanks!

[tekka]

@alterfritz Thanks for the feedback, PR merged to 2.2.0-rc.2

[mfalkvidd]

Excellent work. Thanks everyone!
