Firstly make sure you've got the following packages e.g.:
% sudo apt-get install bluez alsa-utils
To do it you need to make sure all the bluetooth kernel modules are loaded - the following command should show the bluetooth modules if they're loaded e.g.:
% lsmod | grep blue bluetooth 158479 23 bnep,rfcomm,btusb
Then you can check the bluetooth adapter is operational by showing its address info e.g.:
$ hciconfig hci0: Type: BR/EDR Bus: USB BD Address: 00:02:7e:16:0D:0a ACL MTU: 384:8 SCO MTU: 64:8 UP RUNNING PSCAN ISCAN RX bytes:58444 acl:314 sco:0 events:6846 errors:0 TX bytes:4821276 acl:17765 sco:0 commands:152 errors:0
Next you need to switch on your headset and put it into discovery mode (e.g. push and hold the power button or something). Then you get your laptop to scan for it e.g.:
% hcitool scan Scanning ... 00:0B:E4:9A:15:E4 Nokia BH-214
Then you need to pair with this device as follows - It will ask you for the PIN code for your device (e.g. 0000 or 1111 or something) and then it will add it to the list on your machine (you'll need to replace the bluetooth interface 'hci#' with your one in this part e.g. hci0) e.g.:
% sudo bluez-simple-agent hci# 00:0B:E4:9A:15:E4 RequestPinCode (/org/bluez/9261/hci0/dev_00_0B_E4_9A_15_E4) Enter PIN Code: 0000 Release New device (/org/bluez/9261/hci0/dev_00_0B_E4_9A_15_E4)
Now you need to set up the device for use by ALSA sound system - create a file called ~/.asoundrc containing the following (you'll need to replace the bluetooth address with your one in this part) e.g.:
pcm.bluetooth {
type bluetooth
device 00:0B:E4:9A:15:E4
}
Finally you can now play audio to your headset:
aplay -D bluetooth myaudio.wav
Or you can select the bluetooth audio device in other audio apps.
