Hi Marcel!
The log is below. The prog. on laptop listens on the HF channel,
receives connection, sends 3 AT's, receiving responses, closes the
channel, exits. On closing channel SE630 changes icon from HF to BT
connected.
Kind regards,
Victor Shcherbatyuk.

sounds like a bug in the phone. Send in the "hcidump -X -V" for it.

please try 2.6.11-rc5 and check what is in
/proc/bluetooth/rfcomm/{dlc|sock}
Maybe the phones implementation is bad, but actually we can also close
the DLCI 0 at this time if no other RFCOMM channel is connected.
I don't have a SE 630 for testing and so it might be hard to get this
fixed this easy. However send me the application that you are using.

Something with the decoder is wrong here. Please send me the binary dump
created with "hcidump -w <file>".
