I’m using IOT-MCU V1, soldered DIO1 D5 together and my sketch is from [https://www.thethingsnetwork.org/forum/t/arduino-sketch-generator/6542](https://www.thethingsnetwork.org/forum/t/arduino-sketch-generator/6542)

Using the MCCI Library.

It works only one time, (see the data in the console) then die Atmega sleeps and never wakes up again.
