Thank and sorry for the inconvenience.

Hi Marlene,

Do you also try other USB cables? Can other apps of nRFConnect like Bluetooth Low Engey or Programmer detect the device?

Uninstall nRFConnect and install the version you want. Here is the download link https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-Connect-for-desktop/Download#infotabs

Hi Amanda,

Thank you for your feedback and sorry for my late response.

I connected the Power Profiler Kit PCA63511 used on top of the dev kit PCA10040 per USB to my Mac. I tried different ports on the MAC. (Btw, I connected the USB cable to PCA10040 board and not to the Power Profiler Kit). Whatever MAC USB port used, the Power Profiler App does not detect my device (PCA10040).

Do you close the Power Profiler App, update the files and reopen the app to source the files again?

Actually I checked again and I did downgrade to the version 2.3.0 of Power Profiler App --> But the Power Profiler App still does not detect my device (PCA10040 in my case). The Power Profiler App version 2.3.0 supports engine "NRFConnect 3.3.0" and my current NRFConnect engine is 3.6.1. So I would like to try installing version 3.3 of the pc-nrfconnect-launcher. I downloaded the version 3.3 of the pc-nrfconnect-launcher from https://github.com/NordicSemiconductor/pc-nrfconnect-launcher/tree/release/3.3. Now, how do I downgrade the pc-nrfconnect-launcher?

Thanks!
Best regards,
Marlene

Hi Marlene,

Did you try a different USB port?

The PPK1 can work with the latest Power Profiler App, but not all features are available for PPK 1 though. Mostly the missing features are related to triggering since PPK1 does hardware triggering and there are some limitations. The sampling rate is also lower on PPK1.

[quote user=""]to downgrade the Power Profiler App to a version compatible with PPK (I tried already downgrading to https://github.com/NordicSemiconductor/pc-nrfconnect-ppk/tree/release/2.3 following recommendation here https://devzone.nordicsemi.com/f/nordic-q-a/69755/how-to-downgrade-power-profiler-application but it does not seem to apply to MACOs)[/quote]
