5.7.2.1. Setting Up Bluetooth A2DP Profile
To add A2DP support to the VAB-820, first copy and replace the
pulseaudio-system.conf,
bluetooth.conf
to the
/etc/dbus-1/system.d
folder. Next, copy and replace the
system.pa files
to the
/etc/pulse/folder
. These files are located in the EVK/BT_Config
folder of the BSP.
To enable the Bluetooth service, use the following command:
$ rfkill unblock bluetooth
$ hciconfig hci0 up
$ hciconfig hci0 piscan
$ /usr/lib/bluez5/bluetooth/bluetoothd -C -d &
Use the following commands to run the “bluetoothctl” to show the Bluetooth MAC
address and set up pairing mode for the
EMIO-2531 or EMIO-5531
.
$ bluetoothctl
