It certainly looks to me like some issue with power supply.
Have you added a capacitor close to the power pins of the radio?
It's also a good idea to power the radio directly from the power supply instead of through the arduino supply which is very limited.
Thanks for all the input and ideas - I'll go with cr2032 and see how it goes. Batteries, holders and ceramic caps are all on their way, so time will tell on this one.
Thanks all! :)
Thank you, I did find some examples, but when I tried removing and including code I would get a blank screen. But besides that, its a great thing to have under the build section. I'm sure others would benefit, making an awesome thing even better :)
@signal15 that depends on whether you by "turn on" mean require signed messages, if you run the official release or beta release and if you have the relaxed security flag enabled. The documentation describes all possible scenarios. Just make sure you read the version that correspond to the version you use (beta or release).
