How to connecting the Power Profiler Kit to a computer and measuring current without an nRF5 DK?

[zhangchi]

In spec "PPK_User_Guide_v2.3.1" ,chapter " 6.6 Measuring current on custom hardware without an nRF5 DK "

I connect PPK to computer as the picture above, micro USB for power supply and J-Link for PPK connection. But the app "nRF connector-power profiler" can only find J-Link but can't find PPK device.

What may cause this problem? Is this connection method right? Or what kind of J-Link we should use?

Hi

This error refers to a bug that was present in nRFConnect version 3.0.0. Could you please update nRFConnect to v3.1 and check you're running v2.2.0 of the Power Profiler? If you have already, try uninstalling and reinstalling nRFConnect on your computer.

Best regards,

Simon
