RE: Current consumption increase when enabling LIS2DH trigger

Thank you very much, adding sense-edge-mask = <0xffffffff>; to &gpio in my DTS brought the consumption to the expected value range!

I forget where I originally found this advice, but I remember someone suggesting to use Sense for GPIO that aren't very high frequency (as opposed to GPIOTE by default).

I forget what kind of power savings I saw, but it wasn't negligible.

Here's a link that actually mentions using sense for LIS2DH. And here's another talking about general power savings and sense.

For example, in DTS, just

&gpio0 {
    sense-edge-mask = <0xffff>;
};
