[Bluez-devel] alsaplugin into btsco

[Brad Midgley]

Hi

I decided to move the alsa plugin stuff into btsco cvs. Build it with
 ./configure --enable-alsaplugin

I actually think there's something fundamentally wrong about how I'm
trying to make the bluetooth connection. The call that usually fails
looks like:

DEBUG: connect_l2cap: Can't connect to AD:32:30:3C:0D:00 on psm 25.
Interrupted system call(4)

There is something going on with an io signal or something with pthreads
that blows up the l2cap connection. I think we need to do the connection
in another thread or inside a different part of the alsa plugin
handler... any ideas?

Brad

try to use a non-blocking L2CAP socket.

is this set using opts.mode before the ioctl? I'm not having much luck
finding examples or docs.

use fcntl() and F_GETFL/F_SETFL as usual.
