Hi to all.

I want to establish a SCO connection with btsco with two another device (two headset). I need two bluetooth dongle?
At the moment, when I launch two istance of btsco, only the last works.

Using two dongles, hci0 and hci1, how to tell to btsco what interface to use?

Is it possible modify btsco to work with two device or it need kernel changes (snd-bt-sco)? I'm studying source code, but I don't clearly understand the use of bind syscall before the connect.

Thanks in advance!

Cheers,
Pizza

Luca,

It's in our todo list but there is still a significant amount of work to do it...

With two dongles, we would need btsco the daemon to accept a command-line parameter for the adapter to bind to.

With one dongle, we need to load the sco kernel mod with a parameter that tweaks one of the sco settings. This is from memory and it's a bit fuzzy.

Either way, we then need to make multiple alsa devices available using btsco the kernel mod and work out a way to communicate with the corresponding daemon.

Brad,

I could implement the patch of btsco to accept an optional command-line parameter in order to specify the adapter to bind to.
I think it's the easyest way at the moment.

With one dongle, that's a lot of hard work and now I'm not sure I'm able to implement this feature.

After that, I could try to solve multiple alsa device issue.

Thanks a lot.

Cheers,
Pizza
