System administrator but have always loved tinkering with electronics. Started with arduino and quickly went to custom since its just better. Still partially arduino at the root though since I have yet to fully leave the arduino code base.
Alright so I have been tinkering and finally read something that fixed the problem for me. I saw a note about power issues and needed more current then the trace could source quickly. So I grabbed my scope and checked. I was seeing a .6v drop when the TX started. I have now added a 22uf cap between ground and VCC and everything including reboot is functioning correctly. I hope this helps.

I am experiences the same issues where the devices fail to reconnect. But I am using the RF24 Library not the MySensors Library right now.
