README.md

See https://community.volumio.com/t/guide-volumio-bluetooth-receiver/7859

Install dependencies:

sudo apt-get update 
sudo apt-get install dh-autoreconf libasound2-dev libortp-dev pi-bluetooth
sudo apt-get install libusb-dev libglib2.0-dev libudev-dev libical-dev libreadline-dev libsbc1 libsbc-dev

Compile Bluez 5.51:

git clone git://git.kernel.org/pub/scm/bluetooth/bluez.git
cd bluez
git checkout 5.51
./bootstrap
./configure --enable-library --enable-experimental --enable-tools
make
sudo make install

sudo ln -s /usr/local/lib/libbluetooth.so.3.19.0 /usr/lib/arm-linux-gnueabihf/libbluetooth.so
sudo ln -s /usr/local/lib/libbluetooth.so.3.19.0 /usr/lib/arm-linux-gnueabihf/libbluetooth.so.3
sudo ln -s /usr/local/lib/libbluetooth.so.3.19.0 /usr/lib/arm-linux-gnueabihf/libbluetooth.so.3.19.0

Compile Bluez-Alsa

cd
git clone https://github.com/Arkq/bluez-alsa.git
cd bluez-alsa
git checkout v4.0.0
autoreconf --install
mkdir build && cd build
../configure --disable-hcitop --with-alsaplugindir=/usr/lib/arm-linux-gnueabihf/alsa-lib 
make
sudo make install

Configure Bluetooth subsystem:

Create file /etc/bluetooth/audio.conf

sudo nano /etc/bluetooth/audio.conf

add

[General]
Class = 0x200428
Enable = Source,Sink,Media,Socket

0x200428 - Hifi Audio Device, see http://bluetooth-pentest.narod.ru/software/bluetooth_class_of_device-service_generator.html

Update file /etc/bluetooth/main.conf

sudo nano /etc/bluetooth/main.conf

add

[General]
Class = 0x200428

Automate BluezAlsa: Set BlueAlsa as a service Create file /lib/systemd/system/bluealsa.service

sudo nano /lib/systemd/system/bluealsa.service

Add

[Unit]
Description=BluezAlsa proxy
Requires=bluetooth.service
After=bluetooth.service

[Service]
Type=simple
User=root
Group=audio
ExecStart=/usr/bin/bluealsa -p a2dp-source -p a2dp-sink

[Install]
WantedBy=multi-user.target

Enable BluezAlsa starts from boot:

sudo systemctl daemon-reload && sudo systemctl enable bluealsa.service

Set bluealsa-aplay as a service: Create file /lib/systemd/system/[email protected] hw1:0 is the hifiberry audio device I want to use. There may be better way to link it. Use aplay -l or aplay -L to find the device (https://superuser.com/questions/53957/what-do-alsa-devices-like-hw0-0-mean-how-do-i-figure-out-which-to-use).

sudo nano /lib/systemd/system/[email protected]

Add

[Unit] 
Description=BlueAlsa-Aplay %I -Dhw:1,0
Requires=bluetooth.service bluealsa.service

[Service]
Type=simple
User=volumio
Group=audio
ExecStart=/usr/bin/bluealsa-aplay %I -Dhw:1,0
[Install]
WantedBy=multi-user.target

sudo systemctl daemon-reload

Add UDEV rules Create file /etc/udev/rules.d/99-input.rules

sudo nano /etc/udev/rules.d/99-input.rules

Add

KERNEL=="input[0-9]*", RUN+="/home/volumio/a2dp-autoconnect"

Tell Bluetooth how to create a bluetooth->Alsa connection: Create file /home/volumio/a2dp-autoconnect

nano /home/volumio/a2dp-autoconnect

Add

#!/bin/bash
# Run at each BT connection/disconnection start/stop the service bluealsa-aplay
#!/bin/bash

BTMAC=${NAME//\"/}

function log {
  echo "[$(date)]: $*" >> /var/log/a2dp-autoconnect
}

if echo "$BTMAC" | grep -n -E "^([0-9A-F]{2}:){5}[0-9A-F]{2}$"; then
  if [ "$ACTION" = "remove" ]; then
    log "Stop Played Connection " "$BTMAC"
    sudo systemctl stop bluealsa-aplay@"$BTMAC"
  elif [ "$ACTION" = "add" ]; then
    log "Start Played Connection " "$BTMAC"
    sudo systemctl start bluealsa-aplay@"$BTMAC"
  else
    log "Other action " "$ACTION"
  fi
fi

Set the right access permissions:

sudo chmod a+rwx /home/volumio/a2dp-autoconnect
sudo touch /var/log/a2dp-autoconnect
sudo chmod a+rw /var/log/a2dp-autoconnect

REBOOT

After reboot, use bluetoothctl to connect to your bluetooth music source:

sudo bluetoothctl

power on
agent on
default-agent
scan on => xx:xx of your device
pair xx:xx
trust xx:xx
exit

On your mobile, connect volumio. Should work. Once the device is connected you should be able to play something …

Checking

To check if the services are all up and running:

systemctl | grep blue

You should get something like that:

sys-subsystem-bluetooth-devices-hci0.device loaded active plugged /sys/subsystem/bluetooth/devices/hci0

sys-subsystem-bluetooth-devices-hci0:11.device loaded active plugged /sys/subsystem/bluetooth/devices/hci0:11 

bluealsa-aplay@68:FB:7E:24:25:52.service loaded active running BlueAlsa-Aplay 68:FB:7E:24:25:52 -dhw:1,0 

bluealsa.service loaded active running BluezAlsa proxy 

bluetooth.service loaded active running Bluetooth service 

system-bluealsa\x2daplay.slice loaded active active system-bluealsa\x2daplay.slice 

bluetooth.target loaded active active Bluetooth

Debug udev rules

sudo udevadm control --log-priority=debug
sudo journalctl -f

Do you think your tutorial will work with Volumio x86 version? Thanks

Do you think your tutorial will work with Volumio x86 version? Thanks

I never use a x86 version of Volumio. Is Volumio x86 debian based? If so, it should work.
