nRFConnect 3.0.0 unsupported device "serialport"

[Dave_couling]

I updated to nRF Connect 3.0 today and its seemed to causes issues with any Dongles I connect to my PC.  I get the following error:

ERROR Unsupported device with serial number 'CD28EC9EE85A' and traits ["serialport"]

I tried uninstalling and reverting to 2.7 but the issue seems to persist.  I've tested on 3 dongles and I get the same error everytime.

Shows similar except without the "USB: Nordic Semiconductpr nRF52 Connectivity"

This suggests to me that the firmware in the dongle isn't working properly.  I let the nRF Connect attempt to update the firmware once in bootloader mode, but the FW updates always fail.

Here is the log:

I have tested on all available USB port with the same result.

Hi,

Thanks for the update.

You mentioned earlier that a workaround was to program the dongle on a different computer. Was that a computer with an earlier version of nRF Connect for Desktop, or was there another difference between the two?

Yes that other computer had a much earlier version

Hi,

Can you try to program a different hex file onto the Dongle through the nRF Connect Programmer app first? (An SDK example for the PCA10059, so that you can validate that the computer is able to program the Dongle with an application. Also, so that the new application for the DFU performed by the BLE app is different from the one already present on the board, for next step.)

Then, try pressing the button for putting the Dongle into bootloader mode (red light pulsating) before selecting it in the nRF Connect BLE app?

By the way, we just recently released nRF Connect for Desktop v3.3.0, and Bluetooth Low Energy app v2.3.2.

v3.3 seems to fix the issue however it now causes issues with the PCA10031 dongles
