How to make a RFCOMM socket inAndroid without UUID

view full story

http://stackoverflow.com – I want to connect an Android Device to a computer with Ubuntu OS. In the side of Ubuntu I don't need to use UUID but in Android side I should use UUIDs and I think that's the reason I can't connect them. I'm looking for a way for making a socket for Android without using UUIDs but I still haven't find anything for that. Does anyone know how can I do this? (HowTos)
