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

Yes, the PPK can measure down to 1uA, you can zoom with the mouse wheel to get a better look at the graph. And hold in the right mouse button to get lower/higher current values. The Power Profiler can not show the minimum current. What "switch level option in app" are you talking about? The measurement switches automatically. This video should help you understand the Power Profiler App better.

Best regards,

Simon

Thank you for your reply.

But I can't open this video in China. Can you help to provide the written user guide or of Power Profiler app?
