    Help needed to fix Bluetooth

    I need help to re-enable my previously working bluetooth on a Dell laptop (D630) with a "Wireless 360 Bluetooth" adapter.

    When I click on my Bluetooth manager icon->preferences, it says "Bluetooth is disabled" and there is a big Button with "Turn On Bluetooth" which doesn't do anything that I can see. And /etc/init.d/start also doesn't appear to do anything.

    If I use "hciconfig -a" I can see the internal adapter. And with "sudo hciconfig hci0 up" I can enable the interface. Then I can scan with "hcitool scan".
    Here is an example session immediately following a reboot:
    Code:
    $ /etc/init.d/bluetooth status
     * bluetooth is not running
    $ /etc/init.d/bluetooth start
    $ /etc/init.d/bluetooth status
     * bluetooth is not running
    $ hciconfig -a
    hci0:	Type: USB
    	BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0
    	DOWN 
    	RX bytes:0 acl:0 sco:0 events:0 errors:0
    	TX bytes:0 acl:0 sco:0 commands:0 errors:0
    
    $ sudo hciconfig hci0 up
    $ hcitool dev
    Devices:
    	hci0	00:21:86:82:C2:EA
    $ hcitool scan
    Scanning ...
    	00:19:0E:0C:D7:01	BlueZ (0)
    	E4:E0:C5:35:12:B4	DTVBluetooth
    But I have been unable to get gnome-bluetooth (Bluetooth GUI) to work and have not been able to use hcitool to connect to a device.

    Any help getting gnome-bluetooth GUI to work would be much appreciated.
    I've searched through many threads and tried everything that might be remotely related to my problem but to no avail.

    Here is dmesg info (dmesg |grep -i blue):
    Code:
    $ dmesg|grep -i blue
    [   21.031234] Bluetooth: Core ver 2.15
    [   21.036482] Bluetooth: HCI device and connection manager initialized

    install blueman from software center, blueman can turn on bluetooth easily then you can use or setup your bluetooth devices even with gnome bluetooth manager.

    Ok, that was worth a shot but I get an error when I click "System->Preferences->Bluetooth Manager". See attached.

    And:

    try removing bluez then install again, use the command line to uninstall
    Code:
    sudo apt-get remove --purge bluez
    watch the terminal output, if any message that some configuration file or folder is left behind you will have to manually delete it as you will need to completely remove everything to do with bluez from the system then re-install, bluez should work again if you succeeded removing all previous configurations.

    gandaran,

    Thank you for your persistence.
    That "--purge" option did it. I know because I removed and re-installed bluez several times without success.

    So bluetooth is now working again!
    Thanks again.

    Bluetooth not working for me either on installing 12.04

    After installing 12.04 from scratch following an upgrade failure (Grrrrrrr!) and abandoning Unity for Gnome Classic-without-gubbins, I plugged a USB bluetooth adaptor in and found the same problem as started this thread. Following advice on purging bluez appeared to solve this, as there were suddenly lots of options available from the icon in the notification area.

    Unfortunately, an attempt to adjust bluetooth settings failed to open the relevant window, caused the options to disappear from said icon in the notification area and removed the bluetooth icon from system settings. Rather than mess further inexpertly, I'll wait a bit hoping for informed advice
    .
    I think I got that...but then again...
