I'm trying to get a SPK-ProHT Bluetooth speaker and headset working on an

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.
Hi,
I remember there was a kernel problem which prevented some
headsets from working. The bug was introduced in 3.12 and was
fixed in 3.18.
