I concur. Performance issues appear to be resolved in the latest release. I tested on M1 Mac running macOS 13.0 and profiler v3.5.3

I was having this problem also. FWIW this seems fixed with the latest update:

- nRF Connect for Desktop v3.12.1

- Power Profiler v3.5.3

- macOS Big Sur

Appears related to devzone.nordicsemi.com/.../388898

Am also experiencing this issue. The PPK has been working perfectly, I haven't used it for a month or so, came back and it was super slow.

Using a Mac M1.

Have tried v3.12, 3.7 and 3.6.1 with matching profiler app and they all have the same problem

Hi Sirio

Stian is currently on vacation, and I will handle the case in the mean time.

The fix Stian mentioned earlier hasn't been released yet, and the developers haven't been able to reproduce the issue internally so we can't be sure if the update will solve it either.

It would be very helpful if you can try to downgrade the PPK application to v3.0.3, and see if that fixes the issue.

You can download v3.0.3 of the PPK application here.

For this to work you will need to install an older version of nRF Connect for Desktop as well, from the download page here. Version 3.6.1 should work with v3.0.3 of the PPK app.

On Windows you need to put the content of the package folder in the tgz file into the C:\Users\YOUR_USER_NAME\.nrfconnect-apps\node_modules\pc-nrfconnect-ppk folder.

For Unix systems you will find the folder here: ~/.nrfconnect-apps/node_modules/pc-nrfconnect-ppk/

Also, would you be able to check the value of the buffer used by the PPK application?
You can find this by opening the PPK app, connecting your PPK board, and pressing CTRL + SHIFT + ALT + A. Then there should be a setting called "Max size of buffer" that you can read back.

EDIT: I originally wrote v3.6 of the PPK application, this is now corrected to v3.0.3. Sorry for the confusion.

Best regards
Torbjørn

I have this same issue also, but PPK2 is not in stock with either Mouser or DigiKey.

App versions tested which have this issue:

- nRF Connect 3.7.1; Power Profiler 3.1.3 (both WIndows 10 and MacOS Big Sur)

- nRFConnect 3.11.1; Power Profiler 3.4.3 (both Windows 10 and MacOS Big Sur)

The Power Profiler samples ~1.3sec of data in 5sec of wall time

The only instructions I could find for downgrading nRF Connect apps is here: How to downgrade nRF Connect? ... however the link given for apps.json (http://developer.nordicsemi.com/.pc-tools/nrfconnect-apps/3.7-apps/apps.json) does not work with other version numbers, so I cannot test any other version, and as stated above 3.7 is not working.

Would it be possible to please have an estimate on this fix and to have further instructions on downgrading the Power Profiler tool in the meantime to avoid this bug?

Thank you.

Ok I see. I asked for an update, but all I can say at the moment is that the ppk team has received the bug report and is working on the issue, and a fix will probably be released soon. If you are fine with using the PPK2 instead, I guess that's the best solution anyways, as it has newer and updated hardware.

FWIW we decided to abandon the PPK-1 and use PPK-2 which does not have this problem.

Hi, do you have any updates? It's extremely hard to work.

Hi, thanks for the feedback. I will report the issue to the PPK team.

PPK2 does not show this problem.
