Hi Peter,

Unless OP responds here, you can consider making a new case for this as well. Or alternatively try what I suggested.

Could you try reading the register of the GPIO to see how it is configured?

Hey

I am having the same problem, any updates on how to fix this?

Hello again, and sorry about the wait.

However, if I enable a button using the zephyr input subsystem "zephyr,gpio-keys", even just the definition in the device tree, the average jumps to 16.5uA.

Yeah that sounds a bit excessive. I guess that by only adding that definition, we're not specifically making it draw as little power as possible.

Hello Francois,

Just letting you know that I am looking into it, but I'll have to get back to you about this.

I had a quick look at the Zephyr code, the high consumption while sleeping comes from the use of the edge interrupt right?

I reverted to CAF and I can confirm that I don't have this high consumption issue.
