Code: static const nrf_drv_rtc_t rtc = NRF_DRV_RTC_INSTANCE(2); static void rtc_handler(nrf_drv_rtc_int_type_t int_type) { ifen-USTelligent Community 13Thu, 06 Jul 2017 19:05:06 GMThttps://devzone.nordicsemi.com/thread/91668?ContentTypeID=1Thu, 06 Jul 2017 19:05:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:253a6c78-24fe-4e99-b2f5-b7546dbbb69fJ&#248;rgen Holmefjord<p>Hi,</p> <p>Interrupt on COMPARE events is disabled in <code>nrf_drv_rtc_int_handler()</code>. You need to change the interrupt handler, as described in <a href="https://devzone.nordicsemi.com/question/48619/rtc-nrf51-sdk-example-matches-compare0-only-once/?answer=49056#post-id-49056">this answer</a>, or call <code>nrf_drv_rtc_cc_set()</code> in your <code>rtc_handler</code> to enable interrupts for COMPARE events again.</p> <p>Best regards,</p> <p>Jørgen</p><div style="clear:both;"></div>
