I’m using https://github.com/janvl1234/Sodaq_NBIoT_examples/tree/master/Sensors_NB-IoT/Sodaq_NB-IoT_All_Sensors ( a bit adapted to format the data better).
Temp, humidity, pressure and GPS received correctly and shown on AllThingsTalk correctly … but only if I connect the NB-IoT board + Leonardo to my laptop and start the Arduino IDE and the Serial Monitor. It looks like the program blocks if the Serial Monitor is not active. After it started delivering values to AllThingsTalk I am able to close the Serial Monitor and then it keeps sending values.
I suspect DEBUG_STREAM (= Serial). Anyone an idea what is happening with DEBUG.STREAM?
Is anyone using the device with only a power pack for example?
