btsco occasional loud bursts of static

I have a dlink dbt-120 rev. b4 bluetooth adapter with a motorola hs850 and I use btsco to talk with people online. When I have my laptop sitting on my lap, everything works fine. However, when I start to walk around, the sound transmitted to the other person from my headset will have bursts of loud static. I am guessing that this is a problem with the connection being worse. I would like to get this resolved, and I can do some coding as well. I have a 2 MB hcidump which somewhere near the end has the offending sound packets. I can't find any documentation on the SCO protocol, so I can't find where the static was. Can anyone point me in the right direction?

Thank you,
Chase Douglas

One thing to check is the code we have to accommodate a byte getting lost. If we don't watch for this, subsequent samples have what should be a high byte in the low position and vice-versa, so the result is loud noise for the remainder of the connection.

I haven't looked closely at this, but it's really baffling to think a single byte could be lost from a stream of 16-bit samples like that. The protocol should drop entire samples when the signal is bad--losing *half* a sample is a worst-case scenario.

Hi,
We're a group of 4 french students and we have a project to do. We have decidec to pick up a topic from the ToDo list but after searching on the archive, I found that almost all things have been begun. So we would like to know if there's any point that need development. Or maybe I'm wrong and anybody have begin something from the ToDo list (and in this case, i apologize). We need a precise subject because it's a work for the university. Regards, Chi-Minh

ps : sorry if my english is not very comprehensive

The bluetooth audio has todo items (moving into alsa/gstreamer plugins). I've done some of the stereo transmission work without any headset by sending from one pc to another, so it doesn't require special hardware.
