You welcome Nathan. I will await an update from your end then.

I handed this project off to my coworker. I gave him this thread so he may be in contact. Thanks for your help in the meantime!!

I decided to take this case, since Sigurd already had a lot of other cases on his plate 😉

Could you try to enable constant latency mode to see if the problem goes away?

To enable this mode simply run the following code at the start of your program:

NRF_POWER->TASKS_CONSTLAT = 1;

This will keep various system resources running in sleep to ensure fast and consistent timing of PPI events etc, at the cost of higher sleep current.

Best regards
