Hi,
We are currently working on migrating our NRF SDK code to NCS on our custom board with nrf52833/840 and two peripheral devices.
Because we have a higher power consumption in the new NCS I'm trying to optimize our power consumption using different pm states from pm/state.h,
all states provide similar power consumption except PM_STATE_SOFT_OFF which is not relevant to our case.
I try to build and use custom power management without success and would appreciate help/guidance.
Thanks!
