I would suggest reading the RTC chapter (19) in the <a href="http://infocenter.nordicsemi.com/pdf/nRF51_RM_v3.0.pdf">Reference Manua</a>l to get a more thorough understanding of the RTC.</p> <p>Also be aware that app_timer will clear the timer sometimes, so if app_timer_cnt_get() is called two consecutive times the second value may be lower than the first.</p><div style="clear:both;"></div>
