Hi ,
I have that resolved this issue by following these steps:
1.) Steps for resolve BT connectivity issue on NV ref board
a.) Install pulseaudio-module-bluetooth using
sudo apt-get install pulseaudio-module-bluetooth
b.) Edit this file: /lib/systemd/system/bluetooth.service.d/nv-bluetooth-service.conf
remove --noplugin=audio,a2dp,avrcp from this line ExecStart=/usr/lib/bluetooth/bluetoothd -d --noplugin=audio,a2dp,avrcp
c.) Enter above comamnd to start pulseaudio
/usr/bin/pulseaudio --start
d.) Now Check Bluetooth class address using
sudo hciconfig -a
NOTE: If address is NULL than follow step e otherwise proceed further
e.) become a normal user(NOT superuser) and enter following command
/usr/bin/pulseaudio --start
f.) Enter "sudo hciconfig -a" to check the Bluetooth class address (now it will assign)
