Power Profiler Error on v3.2.0

[mcGyver]

Power Profiler software returns an error after I updated it to v3.2.0 with nRfConnect v3.8.0. 

Error message: Error while probing devices: EnumerateWorker json error

Resulting into non detection of Power Profiler Kit ii

Please help. 

Thank you.

Have the same issue on macOS 10.15.7, can't revert back to the old version, because if I download nRF Connect 3.7.2, it wants to download and run the new version of the Power Profiler tool, which doesn't work with nRF Connect 3.7.2.

Hi,

I have reported this internally to the developers, and they are working on it.

Best regards,

Hi,

Our developers are still looking into this issue. In the meantime, a temporary workaround is to downgrade to 3.7 and install app versions compatible with 3.7:

1. Download the latest 3.7 version of nRF Connect for Desktop from https://www.nordicsemi.com/Products/Development-tools/nRF-Connect-for-desktop/Download?lang=en#infotabs (for macOS this is 3.7.2, for Windows and Linux 3.7.1).
2. After starting nRF Connect for Desktop 3.7 a prompt will come up about the 3.8 upgrade. Click “No” on this.
3. In the Settings, click on “Add source”, enter the URL http://developer.nordicsemi.com/.pc-tools/nrfconnect-apps/3.7-apps/apps.json and click “Add”.
4. Back in the list of all apps, all apps should show up twice now, one with “official” below them and one with “3.7 compatible apps” below them. If you want to hide the incompatible versions, click on “Filter” and deselect “Official”.
5. Install the apps you need in the old versions and use them.

I will let you know when the issue is fixed, or if I have any other updates.

Best regards,

Marte

Thank you for providing the work around, reverting back 3.7 version works. While performing the workaround I noticed that the problematic version 3.8.0 of nRF connect is still available for download probably causing many others to run in to this issue. If not already done can the problematic version be removed from Nordic site?

Hi,

Our developers have found that having a JLink device, such as JLink Lite or JLink Plus debuggers, connected to your computer without the device being connected to anything (DK/SoC), will cause this issue. This will be fixed in a new release of nRF Connect for Desktop. I will notify you when this is released. Until then, their solution is to disconnect all JLink devices that are not connected to anything.

Best regards,

Marte
