[gnome-bluetooth] No Bluetooth Found, Plug in a dongle to use Bluetooth

[Bjørn Forsman]

Hi all,

My name is Bjørn, this is my first post to this list.

I'm trying to get gnome-bluetooth working on NixOS, but I'm facing a
blocking issue. This issue also appear on Ubuntu 16.04, so I figure
it's not really a NixOS problem.

The problem:

The "gnome-control-center bluetooth" GUI says "No Bluetooth Found" and
"Plug in a dongle to use Bluetooth", even though I have a working
bluetooth dongle[1].

Turning on verbose output, I see this:

$ gnome-control-center -v bluetooth

What's wrong here? Why doesn't it pick up my bluetooth dongle?

I found this relevant RHEL bug[2], but it's not solved yet.

[1] The dongle shows up in "hcitool dev", bluetoothctl finds the
controller and I can send files with the Ubuntu bluetooth widget in
the top bar.
