RE: Power Profiler Measurement Results

Can you please describe your measurement setup. DK version. PPK version. All switch positions on both DK and PPK. PPK in stand alone mode, or PPK on top of DK. USB connected in which ports. External supply or DK supply. Voltage. External or DK JLink debugger. Etc.

If you can take a picture of the setup that would be great.

What is the application doing?

Start out by measuring on a system OFF example to get the lowest idle current (< 1 µA). Then you know if the problem lies with the measurement equipment/setup or the software:

int main(void){
    NRF_POWER->SYSTEMOFF = 1;
    for(;;){}
}
