| − | ==== Bluez5 & PulseAudio ====
| |
| − | Debian stretch/sid is using BlueZ 5 and PluseAudio 5, which are fairly new.<br>
| |
| − | BlueZ 5 dropped support for alsa, so the solution for now is to use PulseAudio.<br>
| |
| − | PulseAudio 5 only supports the A2DP profile and not HSP/HFP. <br>
| |
| − | * Software to install {{filename|'''pulseaudio'''}}, {{filename|'''pulseaudio-module-bluetooth'''}}
| |
| − | {{Note|{{filename|'''debian-image.tar.bz2'''}} has all these packages pre-installed. Continue to the [[#Start PulseAudio | Start PulseAudio]] section if you use this root filesystem.}}

| − | ===== Bluez5 pairing =====
| |
| − | PulseAudio 5.x supports A2DP per default.<br>
| |
| − | Make sure the following packages are installed:
| |
| − | pulseaudio pulseaudio-module-bluetooth pulseaudio-utils, bluez, bluez-tools.
| |
| − | {{Note|Without {{filename|'''pulseaudio-module-bluetooth'''}} you won't be able to connect after the next pairing and you won't get any usable error messages.}}
| |
| − |
| |
| − | * Start the Bluetooth system:
| |
| − | <pre>
| |
| − | root@cl-som-imx7-sid:~# systemctl start bluetooth
| |
| − | </pre>
| |
| − | Now we can use the {{filename|'''bluetoothctl'''}} command line utility to pair and connect. Run
| |
| − | <pre>
| |
| − | root@cl-som-imx7-sid:~# bluetoothctl
| |
| − | [bluetooth]#
| |
| − | </pre>
| |
| − | to be greeted by its internal command prompt.Then enter:
| |
| − | <pre>
| |
| − | [bluetooth]# power on
| |
| − | [bluetooth]# agent on
| |
| − | [bluetooth]# default-agent
| |
| − | [bluetooth]# scan
| |
| − | </pre>
| |
| − | Now make sure that your headset is in pairing mode. It should be discovered shortly. For example,
| |
| − | <pre>
| |
| − | [NEW] Device 00:07:A4:F2:B3:CB Motorola HT820
| |
| − | </pre>
| |
| − | shows a device that calls itself "Motorola HT820" and has MAC address 00:07:A4:F2:B3:CB.
| |
| − | We will now use that MAC address to initiate the pairing:
| |
| − | <pre>
| |
| − | [bluetooth]# pair 00:07:A4:F2:B3:CB
| |
| − | </pre>
| |
| − | After pairing, you also need to explicitly connect the device:
| |
| − | <pre>
| |
| − | [bluetooth]# connect 00:07:A4:F2:B3:CB
| |
| − | </pre>
| |
| − | If everything works correctly, you now have a separate output device in PulseAudio.<br>
| |
| − | You can now disable scanning again and exit the program:
| |
| − | <pre>
| |
| − | [bluetooth]# scan off
| |
| − | [bluetooth]# exit
| |
| − | </pre>
| |
