RE: High power consumption with interrupt enabled

Thanks nordicator_prim3 ! That worked. I also found an alternative solution (not "better", but FYI); use GPIO_INT_LEVEL_ACTIVE and just disable the interrupt again immediately in the interrupt routine (otherwise it keeps firing).

Hi,

I saw saw current in that ballpark recently. If you're using GPIOTE, then the current consumption can be higher than you would think. If the interrupt pin you need isn't high frequency (sounds like it isn't) then you can use the "sense-edge-mask" dts property on your GPIO node to tell it which pins on that port to not use gpiote on.

I found that originally at this github issue which was made before that dts property was added. Later in that thread, they point to where the fix was implemented here.
