well I have tried Meanies approach to this, and I am getting a "unknown interface" any ideas why bnep is not created?

btw obex seems to work at least from the z to the phone, guess its a start.

lets assume you're connecting from Z to the PC, the latter is running linux

is sdpd running on the PC, and if you use "sdptool browse" on Z does it see the PC? If it won't do anything, try deleting the file /etc/bluetooth/link_key on both, and check the pin.

if sdptool indicates the Z can see the PC, have you tried running pand manually at both ends, connect on Z, listen on PC?
