Hi Vinicius,
More on Key Distribution:
When we are an SM responder, we are suppose to AND the requested key
distribution values with our values (what we expect, and what we
generate). So for instance, if we have 07 07 as our prefered key
distribution values, and we receive 00 01, then we should mask
everything out except for the Responder LTK distribution PRIOR to
responding with the Pairing Response, and then of course only distribute
that one LTK key after link encryption.
Currently, we are always responding with 07 07 regardless of what the
Initiator requested, and then always distribute all possible keys.
Regards,
--
