Sorry for the late reply.

from the spec.

The Bluetooth core system consists of a Host and one or more Controllers. A Host is a logical entity defined as all of the layers below the non-core profiles and above the Host Controller Interface (HCI).

This means that the HOST should contain ATT, ATTDB, GATTC, GATTS, UUID, SMP, L2CAP and GAP
