In the meantime I found the actual error.

We assume it was caused by us calculating the sleep time inside the K_MSEC() macro in a call to k_sleep().

After moving the calculation out of that call, it appears to finally work.

I see, well, I'm happy that you found the solution.

Marking this as verified then,

best regards

Hi Jared

I've already tried that earlier. But as the two Edits stated the error actually lied somewhere else.

I was gonna delete this, when I saw your reply, since the title now has nothing at all to do with the actual problem.

Hi there,

Could you try the workaround suggested here and see if it lowers the current consumption?
