There are a couple of steps to the setup.

Step 1: Install and Enable the Bluetooth Service

[elatov@klaptop ~]$ sudo yum install bluez bluez-libs

After it’s installed you should see the following:

[elatov@klaptop ~]$ rpm -qa | grep bluez
bluez-libs-4.99-2.fc17.i686
bluez-4.99-2.fc17.i686

After the package is installed it should be automatically enabled to be started up on boot.

[elatov@klaptop ~]$ sudo service bluetooth status
Redirecting to /bin/systemctl status bluetooth.service
bluetooth.service - Bluetooth Manager
Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled)
Active: active (running) since Sun, 16 Sep 2012 11:13:11 -0600; 26min ago
Main PID: 589 (bluetoothd)
CGroup: name=systemd:/system/bluetooth.service
└ 589 /usr/sbin/bluetoothd -n

If for some reason the service was not auto started after the install and wasn’t setup to start on boot up, run the following to start the service and to enable the service to start on boot:

[elatov@klaptop ~]$sudo service bluetooth enable
[elatov@klaptop ~]$sudo service bluetooth start

Step 2: Enable HID2HCI

From the Fedora “Documentation/Bluetooth”:

Q: My Dell/Apple laptop (or Logitech dongle) is supposed to have Bluetooth built-in, but doesn’t show up.

A: You’ll need to un-comment the line HID2HCI_ENABLE=true in the /etc/sysconfig/bluetooth file. Start the bluetooth service again with service bluetooth restart as root (or restart your machine) and the Bluetooth device should now be available.

Note: this is not a configuration option in Fedora 11 (updates), and later versions, it is automatic. For Fedora 16 and later, you will need to install the bluez-hid2hci package to enable this feature.

[elatov@klaptop ~]$ sudo yum install bluez-hid2hci

After it’s installed you should see the following packages:

[elatov@klaptop ~]$ rpm -qa | grep bluez
bluez-libs-4.99-2.fc17.i686
bluez-hid2hci-4.99-2.fc17.i686
bluez-4.99-2.fc17.i686

If you want more information on how Bluetooth interacts with HID, I would recommend reading “Manage HID Bluetooth devices in Linux

Step 3: Confirm your Bluetooth Device on your Laptop is Enabled and Available

Check to see if lsusb shows the device:

[elatov@klaptop ~]$ lsusb | grep Blue
Bus 003 Device 002: ID 0a5c:4500 Broadcom Corp. BCM2046B1 USB 2.0 Hub (part of BCM2046 Bluetooth)
Bus 003 Device 005: ID 413c:8160 Dell Computer Corp. Wireless 365 Bluetooth

Check to make sure the device is enabled:

[elatov@klaptop ~]$ rfkill list
0: phy0: Wireless LAN
   Soft blocked: no
   Hard blocked: no
1: hci0: Bluetooth
   Soft blocked: no
   Hard blocked: no

Make sure the device is up:

[elatov@klaptop ~]$ hciconfig -a
hci0:   Type: BR/EDR  Bus: USB
    BD Address: 50:63:13:91:3A:AC  ACL MTU: 1021:8  SCO MTU: 64:1

Lastly make sure the device is available with hcitool:

[elatov@klaptop ~]$ hcitool dev
Devices:
   hci0 50:63:13:91:3A:AC

Step 4: Put the Keyboard in Discoverable Mode and Ensure you Can See it

From “Bluetooth: How to set up your Apple Wireless Keyboard

Now pair the keyboard with the computer:

  1. Press and release the On/Off switch to turn on your wireless keyboard.
  2. The green LED should begin blinking if the keyboard is not already paired and connected to another computer. The blinking LED indicates that the keyboard is in the discoverable mode. If you don’t pair your keyboard with your Mac within three minutes, the indicator light and keyboard will turn off to preserve battery life. If this happens, press the On/Off switch to turn your keyboard on again.

Note: If the LED doesn’t turn on, make sure you have good batteries in the keyboard and that they are properly installed.

While you see the blinking LED, check to see if you can discover the keyboard:

[elatov@klaptop ~]$ hcitool scan
Scanning ...
    B8:F6:B1:02:1C:32       Apple Wireless Keyboard

Also check to make sure you can “ping” the device:

[elatov@klaptop ~] sudo l2ping B8:F6:B1:02:1C:32
Ping: B8:F6:B1:02:1C:32 from 50:63:13:91:3A:AC (data size 44) ...

44 bytes from B8:F6:B1:02:1C:32 id 3 time 29.56ms
^C4 sent, 4 received, 0% loss

Step 5: Pair with the Bluetooth Keyboard

There has been a lot of changes between bluez version 3 and 4. Check out “How Ubuntu’s broken bluetooth support came to be”. With version 3 you could use the instructions laid out in the following articles:

But I was on version 4 and it uses dbus to connect to the device. From what I’ve read you should be able to run ‘bluez-simple-agent’, ‘simple-agent’ , or ‘bluetooth-agent’. For more info check out:

But on my fedora install I couldn’t find any of those tools. I then ran into Manually using Bluetooth. From that article:

Please keep in mind that whenever hcid or pand or hidd are mentioned it means that instructions are applicable only to bluez3 systems which is deprecated ages ago. Modern bluez4 uses only one daemon - bluetoothd and you are supposed to use dbus api directly to configure it. For pairing from command line use simple-agent script.

That article also had link to the simple-agent script. Here is the link. It’s a python script which runs all the necessary dbus calls to pair the devices. You could probably run the dbus calls your self, here are some articles which have examples of the dbus calls:

I just downloaded the script and used it to pair the devices:

[elatov@klaptop ~]$ sudo ./simple-agent.py hci0 B8:F6:B1:02:1C:32
RequestPinCode (/org/bluez/589/hci0/dev_B8_F6_B1_02_1C_32)
Enter PIN Code: 1234
Release New device (/org/bluez/589/hci0/dev_B8_F6_B1_02_1C_32)

When the “Enter PIN Code” shows up, use your regular keyboard to enter a new pin. Then click enter, after that you will just see a blank line, then use your bluetooth keyboard to enter the same PIN and then hit enter. If it works successfully you should see the “Release” message.

Step 7: Connect to the keyboard

After the pairing is complete, go ahead and connect to the device:

[elatov@klaptop ~]$ sudo hcitool cc B8:F6:B1:02:1C:32
[elatov@klaptop ~]$ sudo hcitool auth B8:F6:B1:02:1C:32

Steps 3-7: Use the GUI

If you don’t like the command line, then run “bluetooth-wizard” from a terminal and a GUI will show up which will allow you to complete steps 3-7 without the need to download any ‘simple-agent’ scripts. You can also start ‘gnome-control-center’ and then click on bluetooth. After you are done, your successful setup should look like this:

bluetooth

To use ‘bluetooth-wizard’, make sure the following packages are installed:

[elatov@klaptop etc]$ rpm -qa | grep gnome-bluetooth
gnome-bluetooth-libs-3.4.2-1.fc17.i686
gnome-bluetooth-3.4.2-1.fc17.i686

Step 8: Confirm the Bluetooth Connection

You can use hcitool to check for the successful connection:

[elatov@klaptop ~]$ hcitool con
Connections:
    > ACL B8:F6:B1:02:1C:32 handle 11 state 1 lm MASTER AUTH ENCRYPT

If you want more information, you can do the following:

[elatov@klaptop ~]$ hcitool info 7C:ED:8D:68:E1:7D
Requesting information ...
    BD Address:  B8:F6:B1:02:1C:32

    Manufacturer:  Apple, Inc. (76)
    Features: 0xbc 0x02 0x04 0x38 0x08 0x00 0x00 0x00

You can also use ‘sdbtool’ to confirm the connection as well:

$ sdptool browse B8:F6:B1:02:1C:32

I actually used the bluetooth keyboard to write this post :)
