https://devzone.nordicsemi.com/f/nordic-q-a/32034/how-to-time-between-functions-timer-usedHi. I want to know the time difference between functions by using a timer instead of a difference. I&#39;ve looked at app_timer.h, but it&#39;s hard to understand. I do not need the Repeat function and I just want to be able to measure the time.

If you want to know the actual time, you need some reference to set the time, and keep track time, for instance as shown in <a href="https://github.com/NordicPlayground/nrf5-calendar-example">this example</a>.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
