[g1-hackers] Bluetooth Race Condition

[Andrew J. Yeckel]

I believe what I want to do is disable A2DP.  Can anyone recommend how 
to do this?

Here's the setup:

In my car I have a bluetooth stereo which supports connecting to two 
devices, designated "bt phone" and "bt audio".  I believe this 
corresponds to a "hands free" profile and an A2DP profile.  With my old 
phone (Motorola PEBL), I could connect my phone for hands-free phone 
calls, and I could connect my iPod for music.  I now have an ADP1, 
running JF1.51.  When I turn on my car stereo, my phone connects to the 
"bt phone" profile.  If I get the timing right, I can connect my iPod to 
the "bt audio" profile.  However, if I'm slow, my phone, already 
connected to the "bt phone" profile, also connects to the "bt audio" 
profile.

My current solution, if I miss the timing, is to turn off bluetooth on 
my phone, connect my iPod, and then re-enable bluetooth on my phone.  
This is cumbersome.  I would prefer a solution that simply prevents my 
phone from connecting to the "bt audio" profile in the first place, and 
avoids the race condition of both my iPod and phone trying to connect.

I believe the answer to this is to disable the A2DP profile on my phone.  
I think the way to do this is to edit some files in /etc/bluez.  My two 
problems with that are: (1) I'm not familiar with bluez (though I have 
found documentation online for enabling A2DP), and (2) it seems that 
changes I make to these files are not persisted through reboot.

Does anyone have any suggestions?  How can I make my ADP phone and my 
iPod play nice with each other and my car stereo?

Thanks.
