Dear all,
I've got a linux kernel 2.4.20 with bluez libs/utils 3.23 on a ARM linux
platform.
I can successfully ping and pair my headset, but I am not able to
connect a SCO channel.
As soon as I try to connect a SCO channel (using the scotest utility,
and also other applications) the call always fails with a timeout error.
Here are some useful traces:

scotest[104]: Can't connect: Connection timed out (110)
It seems that the only reply to the Add SCO Connection command is an
unexpected Command Complete event and than the connect() system call
fails with a timeout (40sec) error.
As far as I know the only possible replies to the Add SCO Connection
command should be the Command Status event and the Command Complete
event.
Have you ever experienced this problem ? Any hints ?
Thank you a lot in advance,
Andrea Bondavalli
