Dear STM32 Community,
I have a B-L072-ZLRWAN1 that I have programmed using arduino and the libraries from https://github.com/GrumpyOldPizza/ArduinoCore-stm32l0. I use the board to connect to The Things Network and it works, as long as it is connected to my PC. However, if I try to power the board via the battery compartment, only LED 7 lights up but no connection to TTN happens. Any ideas what the reason could be? I am new to this board and couldn't find a solution in the specs. Thank you for your help and time!
