Bluetooth on Dell Inspiron 15 5547 [Solved]

Postby mhzuchini » Wed Aug 13, 2014 21:43

Nevertheless, there is a control under Gnome that tells me I can turn bluetooth ON and OFF.
But nothing happens... I cannot make this machine visible to others (which should appears as "Foobar" as Gnome says) and cannot see anything through bluetooth.

I suspect bluetooth support is broken. When I run
Code: Select all
dmesg | grep bluetooth
I see nothing.

Am I correct on thinking bluetooth hardware was not detected?

New info about dmesg... sorry, I forgot to take care with capital letters...

That's the CORRECT info about hardware detection:
# dmesg | grep -i bluetooth
[ 17.224823] Bluetooth: Core ver 2.19
[ 17.224835] Bluetooth: HCI device and connection manager initialized
[ 17.224841] Bluetooth: HCI socket layer initialized
[ 17.224842] Bluetooth: L2CAP socket layer initialized
[ 17.224849] Bluetooth: SCO socket layer initialized


Nevertheless, I still can't see anyone nor can be seen through bluetooth...

Am I missing something? I have toggled the Gnome switch ON and OFF with no results.

What a lame I was :oops: ... one have to start bluetooth services before using it...

Well, first of all, test if your bluetooth is really disabled (what seems to be default):
Code: Select all
 ~ # hciconfig
hci0:   Type: BR/EDR  Bus: USB
   BD Address: 90:48:9A:EF:57:0A  ACL MTU: 1022:8  SCO MTU: 183:5
   DOWN
   RX bytes:692 acl:0 sco:0 events:51 errors:0
   TX bytes:1071 acl:0 sco:0 commands:49 errors:0

Then, just start the bluetooth service (and optionally gets its status):
Code: Select all
 ~ $ sudo systemctl start bluetooth
 ~ $ sudo systemctl status bluetooth
bluetooth.service - Bluetooth service
   Loaded: loaded (/usr/lib64/systemd/system/bluetooth.service; enabled)
   Active: active (running) since Fri 2014-08-29 11:19:45 BRT; 10s ago
     Docs: man:bluetoothd(8)
 Main PID: 4319 (bluetoothd)
   Status: "Running"
   CGroup: /system.slice/bluetooth.service
           └─4319 /usr/libexec/bluetooth/bluetoothd

Aug 29 11:19:45 calvin bluetoothd[4319]: Bluetooth daemon 5.21
Aug 29 11:19:45 calvin bluetoothd[4319]: Starting SDP server
Aug 29 11:19:45 calvin bluetoothd[4319]: Bluetooth management interface 1.5 initialized
Aug 29 11:19:45 calvin bluetoothd[4319]: Sap driver initialization failed.
Aug 29 11:19:45 calvin bluetoothd[4319]: sap-server: Operation not permitted (1)
Aug 29 11:19:45 calvin bluetoothd[4319]: hci0 Load Connection Parameters failed: Unknown Command (0x01)
Aug 29 11:19:45 calvin systemd[1]: Starting Bluetooth service...
Aug 29 11:19:45 calvin systemd[1]: Started Bluetooth service.

Although some errors appears, bluetooth will now operate and you can confirm that:
Code: Select all
$ hciconfig
hci0:   Type: BR/EDR  Bus: USB
   BD Address: 90:48:9A:EF:57:0A  ACL MTU: 1022:8  SCO MTU: 183:5
   UP RUNNING PSCAN
   RX bytes:1298 acl:0 sco:0 events:87 errors:0
   TX bytes:1769 acl:0 sco:0 commands:85 errors:0


Last, but not least, you can configure bluetooth service to start at boot, what is not the default. If you want to do that:
Code: Select all
$ sudo systemctl enable bluetooth
ln -s '/usr/lib64/systemd/system/bluetooth.service' '/etc/systemd/system/dbus-org.bluez.service'
ln -s '/usr/lib64/systemd/system/bluetooth.service' '/etc/systemd/system/bluetooth.target.wants/bluetooth.service'

After that, bluetooth daemon starts at boot.

Thanks for your patience.
I hope this "lame" post can help someone else.
