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
