average_measurement_stop() in ppk.py takes more than a minute to execute

[anusha]

Hello Nordic support,

For long term power profiling of nrf52 hardware, I am using the suggestion given here, that makes use of functions in python script ppk.py:
https://devzone.nordicsemi.com/f/nordic-q-a/45770/using-power-profiler-kit-for-average-current-consumption-for-1-hour-or-more

While running the program for the power profiling, I noticed that the function average_measurement_stop takes ~ 70 s to execute and return. Since this function basically just clears the buffer, why does it take a long time to execute? Is there a way to reduce this time?

Thanks.

Hi

I talked to the guy who made the PPK API, and sadly we don't have a workaround for this problem. You could try using the new PPK firmware, found in our nRFConnect app for desktop, as we don't prioritize working on the old PPK any more.

Best regards,

SImon

Unfortunately, the behaviour is the same with the new PPK firmware as well. It would be good to have support for long term logging in nrfConnect PPK app so that we can conduct long term power profiling.
