Re: [Bluez-users] btsco - headset profile activated but no sco packets transmitted ???

[Benny <bennyvasanth@gmail.com>]

Dear Pavel Ruzicka,

I am also involved in testing the BT Headset functionality with the
PC. I am using a CSR based USB BT Dongle on the PC and the BT Mono
Headset is the RFMD Headset kit.

I have taken the latest CVS "btsco" files and compiled. Fedora 3(linux
kernel 2.6.9-1.667) runs on my host PC. I have taken the latest Bluez
libraries and utilities from the bluez site.

After running the "btsco" I am able to run the xmms and play songs and
test for the speaker functionality separately. But I am not able to
test the Sound recorder functionality. The SCO connection is opened
only when I press "play" for the xmms and it closes when I stop the
song. Whether I can test the mic functionality separately.

But my target application is a chat application with the usage of
Speaker and mic working simultaneosly.

Please advice of the setting I need to make.

Thanks & Regards,
Benny
