So far BfA updates android bond state after link key(s) are
distributed. With LE pairing it might happen that no keys are
distributed e.g remote device has Initiator Key Distribution and
Responder Key Distribution set to 0. In such case link is encrypted with
STK and after its disconnected, pairing needs to be done again.
With this patch Android will get update about pairing complete just
after BfA gets pairing complete from the kernel. It solve issue with not
updated Android settings application, which is hanging on "Pairing", in
case when no keys are distributed.
However, bacause Android does not see the difference between bonded /
paired devices and because Android does not allow to update its bond
state if it is not in bonding state, BfA updates Android with BONDED
state on pair_complete with success. This is how we are doing so far
for bonding and non-bonding pairing.
Note: BfA will update its bonded state after link key(s) are
distribiuted.
