Kdeconnect over Bluetooth

Help
1

I’m trying to get kdeconnect working over bluetooth on nixos. The hardware.bluetooth is enabled and I am able to pair my phone but I am unable to see it in kdeconnect. Is it working for someone else?

kdeconect works via networking, not bluetooth. Your phone and kdeconnect need to be on the same (wifi) network.

Kdeconnect has a bluetooth backend as well. I am in a uni and since the uni wifi is eduroam (isolated clients), I am unable to connect with my phone over wifi.

I tried zerotier and tailscale, but it’s a hit and miss with kdeconnect. There are times when kdeconnect won’t detect my linux machine for days, idk why. Bluetooth sounds like a nice alternative but I am unable to get it working on nixos. Here’s an article on this KDE Connect over Bluetooth and a forum Make KDE Connect work with Bluetooth • KDE Community Forums

kdeconnect needs to be compiled with BLUETOOTH_ENABLED=ON in order to work which ours isn’t. PR?

Is it possible to test this on my system? Idk which attributes to override.

Edit: I came up with this, but I am receiving an error.

    (libsForQt5.kdeconnect-kde.overrideAttrs (oldAttrs: {
        cmakeFlags = ["-DBLUETOOTH_ENABLED=ON"];
     }))

But I am getting this error:

CMake Error at /nix/store/0p9j1kpywyy00126mn46ck7wn4qinpr5-qtbase-5.15.7-dev/lib/cmake/Qt5/Qt5Config.cmake:28 (find_package):

  Could not find a package configuration file provided by "Qt5Bluetooth" with

  Add the installation prefix of "Qt5Bluetooth" to CMAKE_PREFIX_PATH or set
  "Qt5Bluetooth_DIR" to a directory containing one of the above files.  If
  "Qt5Bluetooth" provides a separate development package or SDK, be sure it

Need to add the dependency containng Qt5Bluetooth:

pkgs.libsForQt5.kdeconnect-kde.overrideAttrs (oldAttrs: {
  buildInputs = (oldAttrs.buildInputs or []) ++ [ pkgs.libsForQt5.qtconnectivity ];
  cmakeFlags = (oldAttrs.cmakeFlags or []) ++ [ "-DBLUETOOTH_ENABLED=ON" ];
})

@raphi was able to compile, but still can’t find the device.

I think we need the PAN support for bluetooth to make it work Make KDE Connect work with Bluetooth • KDE Community Forums but blueman does not find the net-tools in path.

That’s separate from KDEConnect over Bluetooth (based on my limited understanding of the subject matter.
