[SOLVED] Bluetooth detected but not working

Hi,
I installed arch on my new laptop. Sound, Graphics etc are working except Bluetooth.
System Settings-> Bluetooth says No Bluetooth adapters have been found.

dmesg | grep Blue gives following

[   10.026565] Bluetooth: Core ver 2.19
[   10.026576] Bluetooth: HCI device and connection manager initialized
[   10.026580] Bluetooth: HCI socket layer initialized
[   10.026581] Bluetooth: L2CAP socket layer initialized
[   10.026585] Bluetooth: SCO socket layer initialized
[   10.076714] Bluetooth: hci0: read Intel version: 370710018002030d00
[   10.103738] Bluetooth: hci0: Intel Bluetooth firmware file: intel/ibt-hw-37.7.10-fw-1.80.2.3.d.bseq
[   10.307009] Bluetooth: hci0: Intel Bluetooth firmware patch completed and activated

I also tried to use bluetoothctl, but it doesn't allow me to enter any command just freezes.

hcitool dev also doesn't list device

[samtech@localhost ~]$ hcitool dev
Devices:

I tried to turn on hci0 using hciconfig, after that hcitool was able to find device but KDE still not recognizing adapter.

[samtech@localhost ~]$ sudo hciconfig hci0 up
[samtech@localhost ~]$ hcitool dev
Devices:
        hci0    80:19:34:97:4D:97

Also hciconfig hci0 up/down does not turn on/off bluetooth LED.

Can anyone help to make bluetooh working?

Re: [SOLVED] Bluetooth detected but not working

Did you install bluedevil ?
Did you start the systemd service ?
What about

# journalctl -b |grep -i bluetooth

---

do it good first, it will be faster than do it twice the saint

Re: [SOLVED] Bluetooth detected but not working

# systemctl is-enabled bluetooth

Sorry, my memory may fail a bit, command to be checked.
EDIT
If you get a negative answer you do

# systemctl enable bluetooth

This will start next boot

# systemctl start bluetooth

This will immediately start

Re: [SOLVED] Bluetooth detected but not working

I suspect NM conflicts with bluedevil. Try to disable the option in networkmanager,

Re: [SOLVED] Bluetooth detected but not working

Thanks TheSaint, Bluetooth is working now!

bluetooth service was disabled

But there is still a glitch. When i turn off bluetooth it doesn't turn off it's LED, means it is only turning off bluetooth at software but not the hardware.
While Debian with KDE 4.8 on same machine (dual boot) is able to turn off/on bluetooth hardware as well.

Is there something i can do to turn off bluetooth radio completely?

Re: [SOLVED] Bluetooth detected but not working

The actual problem of bluetooth not working has been solved, so marking thread as SOLVED.
For the second problem 'turn on/off hardware' i will post new thread.

Thanks for your support!!
