The HC-06 draft states for the case with SAC 1 and SAM 11:-
"11: 0 bits. The address is derived using context information and
possibly the link-layer addresses."
There are two cases where this mode is useful:-
(1) Sending to an address in a remote network, where a 128 bit context
contains the entire address and so the link-layer address is not used.
(2) Sending to an address within the LowPAN using a global address
prefix. Here, the context is 64 bits of global address prefix and the
link-layer address is used.
The draft could be clarified by changing the above sentence to " The
address is derived using context information. If the context length is
less than 128, the lower 64 bits are computed form the link-layer
address as defined in [RFC4944]."
