Ok, I plugged that loop into the code and it seemed to be better at 
first, but the disconnects continue. See attachment. (Attachment 
contains output during failure, loops many times, probably only the 
first couple are of importance).

As you can see from the  line (errno=112:Host is down), the headphones 
are disconnected at this point, and I actually have to turn my 
headphones back on.

I should mention that I also use my bluetooth connection, 
simultaneously, with my phone for internet access, and the a2dpd seems 
to get upset whenever I try to grab data from the net. I figured that my 
bluetooth chip should be able to handle this, as I thought that the 
point of bluetooth was to be able to connect up to 7 devices to a single 
chip, and the one I have (integrated into my laptop) says that it is 
v2.0+EDR, which I figured would be plenty of bandwidth. I gave the ppp 
connection a baud rate of 115200, and set the bitpool at 53 (had to 
hardcode, but that's another topic of discussion) which is i think a 
baud rate of 763200. Now, when I had the bitpool set at 33, or 475200 
baud, the behavior was the same, and the headphones would get kicked off 
frequently.

So, I wonder, based on Brad's comment, if the "transfer=-1" is what 
causes the shutoff of my headphones. And, if that's the case, where 
should I go to change the value being written, and what should that 
value be? If I change the "-1" to some junk data, will that collect on 
the client side, and cause issues there, or could the headphone crashes 
be because of collected junk data?

Let me know what you guys think. And thanks for the help so far.
