Sorry this is a very long mail > due to debug logs attached The problem seems to be that connect() fails with "Protocol not supported". This problem has been reported a few times, but I don't know how to fix it. It seems like missing functionality in the kernel, so my guess is that you're missing some bluetooth related driver. If you get it working somehow, please report back how you did it. The bluez mailing list might be able to help better. --Â Tanu
