bluetooth doesn't start

Dieter@be · 2009-08-24 14:46:38

I'm reading http://wiki.archlinux.org/index.php/Bluetooth
The goal is to pair my phone (sony ericsson k810i) with my PC (which has a broadcom dongle)
I got the dongle working by doing 'sudo hcitool hci0 up' and 'hcitool scan' shows my phone.

But now the main problem is, I cannot pair my phone with my pc:

dieter@dieter-ws-a7n8x-arch ~ hcitool dev

    hci0    00:02:72:C4:7C:06

    message, timeout)

http://www.adamish.com/blog/ suggests that bluetoothd is probably not running, and this is correct.
However, i fail to make it run:

To try to find out why it starts, but exits again, I tried strace but I don't really see what's up:

dieter@dieter-ws-a7n8x-arch ~ sudo strace -f bluetoothd
execve("/usr/sbin/bluetoothd", ["bluetoothd"], [/* 17 vars */]) = 0

Dumb question, but is dbus running? I always have it running on my system, so I have no idea if its required. If you don't mind a bit of 'bloat', I'd recommend blueman for managing your bluetooth, got mine working that way.

Aha I'm a step further. As per http://bbs.archlinux.org/viewtopic.php?id=65935, I needed to HID2HCI_ENABLE="true" and restart the bluetooth daemon. Weird..

Now "sudo bluez-simple-agent" registers the agent and "listens". But when I make my phone search for new devices, it doesn't find my pc.

I kinda sortof succeeded.. I guess http://www.archlinux.org/pipermail/arch … 07077.html
