Hi Rihab,

No need for that, as you have already got my experienced colleague Håkon on the case.

Kind regards,
Øyvind

Since you are using bsp module you are using app_timer and you have to use app_timer API to ensure correct operation. Use app_timer_cnt_get to get the current counter value of the RTC and app_timer_cnt_diff_compute to calculate the difference between to RTC counter values. If no timers are running the app_timer module will stop the RTC, so if you have no timers running create a "dummy" timer.

Have you started LFCLK? For example with:

NRF_CLOCK->EVENTS_LFCLKSTARTED = 0;

NRF_CLOCK->TASKS_LFCLKSTART = 1;
while(NRF_CLOCK->EVENTS_LFCLKSTARTED == 0);
