https://devzone.nordicsemi.com/f/nordic-q-a/68007/high-current-consumption-when-using-timerI have a custom beacon application that is mostly idle. Before adding a timer, the current consumption was 3.2uA. After adding the timer, the current consumption jumped to over 400uA. The timer is used to start the advertising once or twice a day.

I suggest you try utilizing the app_timer for these kind of timers. The app_timer will use the RTC (Real Time Counter, which is the Low frequency timer). This is more power efficient.&nbsp;</p> <p>Look at the implementation in e.g. the ble_app_hrs example for how to use the app_timer.&nbsp;</p> <p></p> <p>Best regards,</p> <p>Edvin</p><div style="clear:both;"></div>
