I have a permissions problem on openSUSE with Bluetooth /dev/rfcomm0. I've written a small test application which opens /dev/rfcomm0 and sends a request message and retrieves a response message. At first my problem was a permission denied error on /dev/rfcomm0 until I added the user account to the dialup users group. Now I get a System.IO.IOException Interrupted system call error whenever I run the app.

I can sudo my application and it runs fine. I'm not sure how and which permissions to set to get this work work under my normal user account.

Guess this should be on Stack Overflow since it's quite programming related. – Shiki Jun 12 '10 at 18:42
Not sure it is actually a programming issue since sudo works. I've also asked this on SO with more details as to the exception trace. – Chief A-G Jun 12 '10 at 20:55
