The bluetooth profiles are attached.

Note the earphone works fine on Android phone and with the same laptop using Ubuntu.

I am using Fedora 34 , latest version. Please advise.

Can you pleas try an older kernel version. Press ESC while booting and choose an older boot option.

Is your Desktop Environment KDE or Gnome ?

Note sure if this is kernel issue. Will try it anyway :+1:

It’s kdeconnect , using in Gnome.

You are right it is not a kernel issue:

Fedora uses since 34 Gnome 40 …

Supported platforms

  • Computers running Linux with Plasma 5, Gnome 3, Elementary OS… any distro with Qt5 support given a little work :slight_smile:
  • Android, by installing the KDE Connect app from the Play Store or F-Droid.

You may want to try/find out if this is Gnome 40 compatible:

Thanks.

That seem fixed the issue :slight_smile:
