Hi Marcel

I investigated the RFCOMM disconnect problem in more detail and found out
that when the device is a listener, it expects the initiator of RFCOMM
connection to disconnect dlci 0. But all devices don't send RFCOMM DISC for
dlci 0. For ex PTS doesn't disconnect dlci 0 in case of HS profile testing 
Test Case: 
-> IUT (BlueZ) is HS Gateway, PTS is HS
-> PTS initiates connection and then disconnect
-> RFCOMM data channel is disconnected by BlueZ but it waits for PTS to
disconnect RFCOMM control channel which doesn't happen.
-> As a result test case fails

The HS Spec says HS Gateway is responsible for disconnecting the connection.
In that case I think there is a misbehaviour here.

If there is something I am missing in understanding the RFCOMM
implementation and this problem, please correct me.
Otherwise do you have a patch to solve this problem, wherein the listener
disconnects dlci 0?

Thanks and Regards,


Sumeet

Hi Sumeet,

I was talking about a recent 2.6 kernel. Not some ancient RHEL4 kernel.

Marcel
