nRF Connect for Desktop Bluetooth Low Energy fails

Torsten Robitzki

Hello,

after a longer time, I wanted to use nRF Connect for Desktop again, to figure out what exactly my device under development is advertising. I upgraded to the latest version of nRF Connect for Desktop Bluetooth Low Energy (v4.0.4), which fails with the following message <Failed to get the library versions: JLINKARM_DLL_COULD_NOT_BE_OPENED>, when trying to run it:

2024-11-21T15:01:21.177Z DEBUG Application data folder: /Users/todi/Library/Application Support/nrfconnect-bluetooth-low-energy/bundle

I've upgraded to the lastet Segger Jlink software (V8.10h). nrfjprog can see both attached JLinks (one actual and an nrf52 eval board).

Any idea, how to fix that?

OS: MacOS 15.1.1

best regards

    Ok, I see.

    I talked to our nRF Connect for Desktop team, and they said that they had seen this before. The nRF Connect for Desktop -> Bluetooth Low Energy app is, unfortunately archived, but at the same time, a replacement has not yet been made. The reasoning is that it is based off of the old SoftDevice implementation from the nRF5 SDK, so it will not be possible to add new features to it. What you can try is to roll back a version or two, and see if that helps (roll back the version of the Bluetooth Low Energy application, that is). 

    If not, is it possible to use the nRF Connect for Android/iOS? They have much of the same functionality. Although I see that the desktop version has it's advantages, and I tend to use it a lot myself, so I understand if that is not ideal. 

    Also, if you have a windows computer, it should still work there.

    I am sorry for the inconvenience, but this is the state of the Bluetooth Low Energy app as it of today, at least.

    Best regards,

    Edvin
