Hi, Lukasz
Thanks for your reply. Following you steps, the previous problem has
been resolved, but it seems that the connection is not stable. When I
execute av connect, I can hear "Connected" from my Bluetooth headset,
but it will be disconnected immediately which i can hear
"disconnected". And it will prompt "I/bluetoothd( 1061):
bluetoothd[1062]: Unable to find matching endpoint". Is this a bug? can
you give some advise?

Hi, Peers
Thanks for your hard work that let us can experience BlueZ for Android. But
I am faced with a audio/a2dp problems that stick me many weeks.
I’m try to port Bluez to kitkat 4.4.3, and many common profiles, such as
HIDP/FTP/GATT can function successfully. But the A2DP profile failed.
So, I try to debug it using haltest tool as follows(with USB Bluetooth
Dongle):
1.bluetooth init
2.bluetooth enable
3.bluetooth get_profile_interface a2dp
4.bluetooth start_discovery
5.bluetooth create_bond xxxxxxxx
Here you should setup A2DP using "av connect <bdaddr>." (don't forget
to do av init before.) Once you are connected you can open stream.
6.audio init
7.audio open_output_stream
Then it will prompts:
D/BlueZ ( 1106):
external/bluetooth/bluez/android/hal-audio.c:audio_open_output_stream()
D/BlueZ ( 1106):
external/bluetooth/bluez/android/hal-audio.c:ipc_open_stream_cmd()
E/BlueZ ( 1106): audio: Invalid cmd socket passed to audio_ipc_cmd
E/BlueZ ( 1106): audio: cannot open output stream
when I debug it , I found that
BlueZ ( 1106): external/bluetooth/bluez/android/hal-audio.c:ipc_handler()
Waiting for connection ...
And it seems that there is no audio socket to connect it.
I’m not familiar with Bluez stack details, can you give some advice? What
should I do to enable audio/a2dp functionality and execute audio play
command? Thanks.
