https://devzone.nordicsemi.com/f/nordic-q-a/98955/high-idle-current-with-smp-server-example-on-nrf5340dkI ran into a high idle current ~500uA on a custom board using the nRF5340. So I’ve reverted to working with the nRF5340dk, isolating all the modules I’m using, and making sure I can drive the idle current down as far as it goes in each case.
