Idle mode between advertisements

[Radu B.]

Hello,

I am using nrf51822 with softdevice 110.

I have noticed that there is some power usage between advertisements, that is more than what is being used when no advertising is active. It looks like this: http://imgur.com/n1ttnna

Since I expect no connection between advertisements ( 850ms apart), is there a way to make the system go to idle mode between them ? It would seem this would improve power usage quite a lot.

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.
