Cannot update modem (nrf9160) with "nrf connect 3.8.0"

Modem DFU failed with error: no matching trait found

Installing older versions eg. 3.7.1 -> have issue with Programmer v2.0.0

Hi,

Were you able to update the modem with nRF Connect for Desktop 3.7.1 before you updated to 3.8.0?

I have reported this internally. In the meantime, you can try to downgrade to 3.7.1 and install app versions compatible with 3.7.1:

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

Best regards,

Marte

Yes, I was able to update the modem with nRF Connect for Desktop 3.7.1 before I updated to 3.8.0.

Now I followed your instructions to downgrade to 3.7.1. and have installed the Programmer app version comatible with 3.7.1.

With the 3.7.1. version it is working again.

Hi,

I am happy to hear that you are able to get it working with 3.7.1 again!

I will let you know when I have any updates from the developers regarding this issue.

Best regards,

Hi,

We have just released v3.9.0 of nRF Connect for Desktop, which includes fixes to make enumeration more robust and increase the timeout when enumeration takes a long time. The version is not on the download page yet, but you can update to it directly in the app, and you can find the release and release notes here nRF Connect for Desktop releases.

The developers have also found that the JLink version that is bundled with the latest version of nRF Command Line Tools causes errors in nRF Connect for Desktop. They are working on a fix for this as well, but a temporary workaround is to downgrade JLink to a known working version, v6.88a, from https://www.segger.com/downloads/jlink.

Best regards,

Marte
