RTC0 is also used by the SoftDevice, so you should change the calendar example to use RTC2 instead. This&nbsp; could be done in nrf_calendar.h like this:</p> <p><pre class="ui-code" data-mode="text">#define CAL_RTC NRF_RTC2 #define CAL_RTC_IRQn RTC2_IRQn #define CAL_RTC_IRQHandler RTC2_IRQHandler</pre></p> <p>&nbsp;</p><div style="clear:both;"></div>
