I'm working on B-L072Z-LRWAN1 lora discovery kit and i have an issue.
I'm able to upload my program on STM32 and it run when the STM is plug in on USB STLINK.
My issue is when i want run my STM on 3AAA battery.
I just have the LD7 LED and my program (send data with LoRa) seems to not working ...
Have you an idea ?
PS : i use the EndNode Cube default project
