https://devzone.nordicsemi.com/f/nordic-q-a/13638/can-i-change-the-priority-of-rtc2-when-used-along-with-softdeviceHi, we are using RTC2 with APP_IRQ_PRIORITY_LOWEST. But the code hanged inside the interrupt handler. when we did step through debug, we came to know that in nrf_drv_common.c file, there is a following condition which blocked RTC. #ifdef SOFTDEVICE_PRESENTen-USTelligent Community 13Wed, 04 May 2016 09:05:47 GMThttps://devzone.nordicsemi.com/thread/52107?ContentTypeID=1Wed, 04 May 2016 09:05:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:777e8e44-017f-4318-9f12-fd8d88f83501Pavithra<p>Thank you.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/52106?ContentTypeID=1Wed, 04 May 2016 07:56:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a399ae5e-3121-4069-b8f0-47531d034952Susheel Nuguru<p>I think this module is not updated with new priority levels (and added enumvalues). Hence it is a bug.</p> <p>What you did is right but you forgot one enum too</p> <pre><code>#ifdef SOFTDEVICE_PRESENT ASSERT((priority == APP_IRQ_PRIORITY_LOW) || (priority == APP_IRQ_PRIORITY_HIGH) || (priority == APP_IRQ_PRIORITY_MID) || (priority == APP_IRQ_PRIORITY_LOWEST)); #endif </code></pre><div style="clear:both;"></div>
