Hello to all,
I'm working with Berlin + COM Module and I'm trying to play audio to a bluetooth headset.
I'm able to perform pairing with bluez-simple-agent and connection is estabilished:
I entered the following in /etc/asound.conf
When I try to play with aplay I can see something change in connection:
but no audio is played. Also, after a while I see a lot of debug messages on serial port like the following and connection is lost.
Please, what I'm missing?
Thanks in advance for any answers

Hi Fabiano,
Use the BT (audio down/up link) it's not easy, probably you should start looking the audio driver due all audio / BT is integrated in the same module so take a look here:

Page: 703
There you've the Audio module diagram, see at top left, there you've the BT paths (green is connected to CSR BT audio, blue is connected to DM3730), probably the right choice is use the audio kernel module for configure it as you need for your application ...

0Hi fabiano,
Please check if TPS65950 has the bluetooth function enabled:

0Dear Fabiano.
When you say that you can pair your COM Module and your headset, using bluez-simple-agent, which is that? A shell script?
I'm trying to connect my COM Module to an Android device during 2/3 weeks, but I can't establish a connection. Which are the shell commands you used to connect them?
Thank you
