No operation of the DUT possible in ampere mode (without measurement) #42

leostitzing commented 4 months ago

When I use the Power Profiler app from nrf Connect for Desktop and activate the Ampere mode (without starting a measurement), my DUT runs without any problems. If I try this with the ppk2-api-python, my DUT does not start up. It seems that a setting is missing when activating Ampere mode that allows the DUT to run even if a measurement is not started. Since I want to flash the DUT with the PPK2 connected, this function is very important.

That is because the official software sets an initial voltage, whereas this implementation does not. Please do <PPK2_API instance>.set_source_voltage(<source_in_millivolts>) before starting it in amperemeter mode as the API needs the voltage to do calculations.

Hi @wlgrd, thank you! Now it works like a charm.
