Hi,

The simplest is to power cycle the board and not start a new debug session. You could event disconnect the debugger to be on the safe side. You could also disable logging in just in case, though RTT logging should not have a significant effect as long as you don't actually read it (by enabling the debug interface using for instance a RTT viewer).

hello Einar Thorsrud.

Thank you for your kind response.

Currently i have doubt on ,how we can terminate the debug session before entering system off mode?

By disabling the RTT log ,will debug session be terminated?

Thank you.

Hi,

The nRF52832 will not actually enter system OFF mode when it is in a debug session. Instead, it will use emulated system OFF, which is essentially an eternal loop. So in this case the CPU will be active, consuming a lot of current. You should get the expected behaviour if you test without having a debugger connected.
