Thanks, that's very helpful. I added the 0x0206 and 0x0207 but NOW i
see i didn't do it correctly based on your information.
btw i tried running 'bluetoothctl' on a machine running mainline Linux
kernel with 'hcidump' running on the FreeBSD machine, kinda looks like
a good way to find issues/debug. I don't yet see how to query from
FreeBSD so that it's 'parsing' the sdp records.

hcidump log https://gist.github.com/waitman/c3f8a3bc9b046e36dbb5
it's showing me the 0x0206 is incorrect, but now i think realize how
it should be structured based on your information. Thank you.
