https://devzone.nordicsemi.com/f/nordic-q-a/105838/ppk2-unable-to-show-nrf52840dk-current-drawHey I have a Power Profiler Kit 2 that I want to use to measure current from a nRF52840DK, but the profiler software is only showing 0-0.8uA, regardless of whether the DK is powered on or off. I&#39;ve connected the PPK and DK as shown below.
