Power Profiler Kit II - App v3.4.3 - timescale?

[Achim Kraus]

Using the Power Profiler Kit II with

nRF Connect for Desktop (v 3.11.1) on Ubuntu 20.04 with the Power Profiler App v3.4.3

I'm wondering about the value of the time axis.

E.g. is send two messages. According all other logs, the second message is sent about 50s after the first.

According the Power Profiler, it's about 16s.

Also according this second screenshot, the time span (start - stop) in the log window is about 2:20, in the chart it's about 43s.

Seems, that the times displayed in the must in the chart must be multiplied by 3.

(As secondary issue, the value of charge must be multiplied by 3.)

Using Windows 10, the times are well ;-).

That issue seems to depend on the used USB port!

I use the nRf9160-DK and the "Trace Collector V2 preview, v0.3.2" in parallel.

If is switch my USB ports of the PPK and the nRF9160-DK, the times are valid.

But if I switch them back, I the displayed time doesn't match.

Sounds like a bug, I will report this internally.

Just to say:

It may be not that easy to reproduce it. (Which, of course, is also a sign not to fix it ;-) ). If the developera want to fix it and need some log or similar information, let me know.

Hi Achim,

Based on your knowledge, can we use Power Profiler Kit to measure current for other boards apart from the DK kits.

Tks.
