Hi,

Are you using that, or to you have the PPK connected to a DK (which you can even if you are measuring current of a external DUT)? The current PPK software does not work correctly with an external J-Link. Also, at which position are the switches on the PPK? You can find the correct setup for various configurations under Configuring Power Profiler Kit. If you have a DK, you should follow Measuring current on custom hardware with nRF5 DK.

A common problem which causes the app to not work is if you accidentally program the PPK with firmware that was intended for the DUT. You need to disconnect the PPK or put the COM switch to the "wrong" position (e.g. EXT if it is connected to the DK) if you want to program the DUT, and then put it back when you want to use the PPK to measure current. If you have accidentally flashed the firmware, then you can erase it and program the firmware that was shipped with the old python based PPK software. You should then be prompted to upgrade when you select it from nRF Connect.

Hi Einar,

Sorry for the late reply.

I have tried to use the newer app, but every time I am facing the issue of detection of serial COM port. In an older version, it was detected but the app was not working.

What should I do?

Hi,

The old version of the PPK software that you are using has a number of issues. Can you try using the newer PPK app for nRF Connect for Desktop instead?
