Not connecting with SPP_CA, no rfcomm channel.

[anneranch]

After Blueman is running , it identifiers several Bluetooth devices - including SPP-CA.
The remote Bluetooth device (SPP_CA) light is flashing - as it shoud...
Selecting its icon , I get options - including "Connect to : Serial".
After "Serial" is selected - the pop-up menu goes away, and I get small pop-up with "Connecting" message. Then at the bottom left I get "progress bar", and after few seconds I receive an error message to the effect that rfcomm channel was not established, the remote device LED keeps flashing - hence there is no connection.

My question is - what am I missing in my procedure ?
