Debugging Mode Only When Supplied With External Supply

[Burnie Barren]

Hello,

I am running ble_app_beacon on nRF52 DK. To check functionality, I try with all power sources in turn, i.e. USB cable, battery and external source. Today I realized that only when supplying with external source, the board starts in the debugging mode, i.e. draws an additional 1mA. When I press the reset button it returns back to normal but this did not happen before today. Why do you think this is the case and how can I fix this?

Thank you for your attention.

Hi there,

How do you determine that the chip inters debug mode when you use external supply versus the other configurations? Is it based only on the current draw?

Hello Jared,

Yes, and on returning to nominal values after pressing reset button. What am I missing?
