I am using the MDBT50Q-1MV2 which has the nRF52840, and have burned the Adafruit Feather Express bootloader using a J-link and the Arduino IDE. The issue is that I have not been able to get the current below ~2.4mA and that is using the systemOff(); function. I am not sure if I am stuck in debugging mode and if I am, how do I get out of it? If its not in debugging mode, then I am also stuck as I have tried many different sleeping function and have not gotten any lower current values.
