I connected my Arduino MKR GSM 1400 to the OTII arc using external power supply (7.5V from an adapter) through the 7-9V port, and connected it to the computer using USB port to supply 3.7V.
The current that I measure in the idle state (using both ArduinoLowPower and RTCZero library) is about 9-10mA after pulling up the floating pins as suggested.
This value is much higher than the 3mA as suggested in your video (https://www.youtube.com/watch?v=YVho42UC43Q&t=156s).
Could you kindly advice what I’m doing wrong here to get an idle current so high?
Thanks and Regards,
