hi list
i am trying to implement handsfree profile on my system.
i have downloaded a application which works to make my linux system a headset.
i am using a Bt dongle and trying to connect my nokia 6600 to my system.
i am able to pair them, and establish a ACL connection between them.
but i cant establish a sco connection. The RING code is being received on the system.
but not being heard. Some commands are being exchanged.
My doubt is what is the socket or interface from where the audio data can be received?
Is it a socket ID got from SCO connection?
I am really in trouble with this?
i am sending the log of hcidump command
[root@localhost dev]# /usr/local/sbin/hcidump -V -a
