Hello!
I use BT5, and bluetooth works fine. (2.6.38)
I`ve upgraded it to R1 (2.6.39.4), and that caused trouble with my bluetooth connections.
When I run hciconfig -a hci0 - ok, I see the device, it`s up and working
hcitool scan --all - ok, I can see the device I`m trying to connect with. But when I run sdptool browse %bd_addr% - I see this error

Failed to connect to SDP server on %bd_addr%: Protocol not supported

So, the question is - how to fix this? I`d like 2 use R1, but with working bluetooth...
