nRFConnect for Desktop 3.9.0 still has problem with JLink

[choehyunho]

Hi teams,

I noticed nRFConnect v3.9.0 is released.

After upgrading it, I got different errors as following, while detecting my nRF dongle & PPK during BLE app & Power profiler app.

2021-11-10T04:47:51.051Z ERROR Error while probing devices, more details in the debug log: JLINKARM_DLL_ERROR
2021-11-10T04:47:51.051Z DEBUG "Error when running nrfdl_enumerate"

As it says, I tried to find debug.log, but don't know where to find. Let me know if further problem details required.

I am using two J-Link devices and several nRF52833 DKs on my desktop, and using another BLE vendor's board, too.

I can roll back to 3.6.1, and continue to use nRFConnect, but it is quite inconvenient and hope this problem solved.

Is this problem only for my case? I searched forum but no one reported this isssue yet.

I am encountering also similar issue. Since update to 3.8.0 and nRF programmer v2.0.0, i get an error with listing devices (it was an "observer/json" thing in v3.8.0, now i get the "Error while probing devices, more details in the debug log: JLINKARM_DLL_ERROR". In both cases it prevents me from getting my DK showing in the list of connected devices.

With/without usb hub does not change the behaviour. The issue happened immediately after updating to v2.0.0 and v3.8.0 for nRF programmer and nrf Connect respectively.

I am downgrading to previous version. Will let you know if the problem disappears.

[EDIT] By the way, the Bluetooth Low Energy was also not discovering devices, like the nrf52 USB dongle. The devices list was also empty. Had to downgrade it as well.

So after downgrading following this post, it works again perfectly with my DK (i downgraded to v3.7.1). Please Nordic, do something to fix your app ! You can contact me if you need more info.
