Hi all,

One of the things I have never been able to get working on any of my Linux systems is bluetooth. Despite having it on several systems there has always been something which has prevented it from functioning. Back in ~2006 this was understandable, but given we're now in 2018 I've finally decided to take another look.

My motherboard has an integrated BCM20702A1 HCI, for which firmware is not available in the kernel. So following the dmesg output I found the firmware online and placed it into the relevant directory. Thus
Code:

[274918.809128] Bluetooth: hci0: BCM: chip id 63
[274918.810109] Bluetooth: hci0: BCM: features 0x07
[274918.826132] Bluetooth: hci0: Fluorine
[274918.827133] Bluetooth: hci0: BCM20702A1 (001.002.014) build 1714
[274919.544137] Bluetooth: hci0: BCM20702A1 (001.002.014) build 1714
[274919.560157] Bluetooth: hci0: Bluetooth USB module

with this I decided to try and run bluetoothctl to get everything up and running. My normal user, freddie, is in the plugdev group and the bluetooth service has been started. However, when I run it, I get:
Code:

freddie@fluorine ~ $ bluetoothctl


where it simply hangs indefinitely. As root
Code:

fluorine # bluetoothctl
Agent registered
[bluetooth]#
[bluetooth]# quit

which I understand to be the expected behaviour. What am I doing wrong and how can I debug this?

I'd like to finish setting up my bluetooth, so let me see if I can help you get as far as I got. I can see devices and pair them, but have not gotten sound to work.

I use genkernel, dunno if that really matters, but it might have filled in some blanks for me automatically.

These are the packages installed on my system. I don't recall which I installed directly and which got pulled in as dependencies:
qtbluetooth
bluez-alsa
blueberry
bluez
bluez-tools
gnome-bluetooth (I use xfce4, I avoid directly installing gnome libs, so this is probably a dep of something else.)

I also have +bluetooth use flag in make.conf.

I have bluetooth and bluealsa in my default runlevel. Blueberry scans for and finds devices and connects to them, but as I mentioned, no sound for me yet. Bluetoothctl connects to agent.

Check for the items I mentioned above and play around for a bit and let me know if you make any progress.
