are you implementing your own or deploying what we have in bluez?

the tables have changed a lot from the spec--there was some math we
could precompute and that meant rebuilding the tables. We also changed
to fixed point, so it would be hard to recognize the original values.

If you don't already have the spec you'll find it at bluetooth.com
