Actually I faked both when I posted it. Most devices don't have c0:ed

That's good to know. I think that I have these set...

The whole pairing thing is kind of ugly atm in FreeBSD. I used big
hammers, I think, to make it work. In other OSes, I just see what is
discoverable, click a couple of times, maybe enter a PIN and I then
promptly forget about it until I have to 'unpair'.

: that is probably fixed pin 0000 if not in the documentation
Yes, it is :) The default is to no pin, so it wasn't authenticating.

It is ok. Not as good as the happy hacking keyboard, but certainly
nice enough to use. Better than most to my feel, but ymmv.
btw, is there some way I can easily list the paired devices?
