Just to conclude this particular thread, the power usage was indeed caused by the RTC. The jitter between the advertisements were actually RTC ticks.

Yes, looks like something is turned on. What is the actual power consumption we are seeing her?

It is my own code, but the code blocks when calling sd_app_evt_wait since there is no event to be handled. I have set a LED to be turned on if that function ever returns, but that is not the case. I currently suspect it is a running timer/rtc but no rtc/timer interrupt is called. The frequency of the spikes (the zoomed in part is not shown in my picture) matches the configuration of the RTC, but it should be disabled.

Is this an SDK example? What do you do in your loop while advertising? Can you try to call this function: static void power_manage(void) { uint32_t err_code = sd_app_evt_wait(); APP_ERROR_CHECK(err_code); }
