Thanks for your answer. I found out what my problem was. There are 2 functions named "RTC1_IRQHandler" : one in "app_timer.c" and another in "nrf_drv_rtc.c". I wrongly used the function from "nrf_drv_rtc.c". The moment I enabled the function from "app_timer.c" - everything worked fine.

Hi yaron. In my case when no soft-device is enabled and wants to use timer, I use this function.

static void lfclk_config(void)
{

    /* enable clock as Internal 32KHz oscillator*/

    NRF_CLOCK->LFCLKSRC            = (CLOCK_LFCLKSRC_SRC_RC << CLOCK_LFCLKSRC_SRC_Pos);
    NRF_CLOCK->EVENTS_LFCLKSTARTED = 0;
    NRF_CLOCK->TASKS_LFCLKSTART    = 1;

    while (NRF_CLOCK->EVENTS_LFCLKSTARTED == 0)
    {
        /* Do Nothing */
    }
    NRF_CLOCK->EVENTS_LFCLKSTARTED = 0;
}
