In order to measure time of a button press, I would use the <a href="https://www.nordicsemi.com/DocLib/Content/SDK_Doc/nRF5_SDK/v15-2-0/lib_timer">Timer library</a>&nbsp;(app_timer.c/h). Which uses the low frequency RTC, and is <a href="https://devzone.nordicsemi.com/f/nordic-q-a/10952/timer-vs-app_timer">sufficient for your needs</a>.</p> <p>The way I would go about measuring the time, is to create a timestamp on button push and button release, and then calculate the difference.
