    BlueZ Core in that diagram is the main host stack software. It communicates with the BT hardware using HCI protocol to do general control of the hardware. You would have to read the BT spec to get a full picture of what all of the HCI protocol commands do. But at a high level there are things like reading HW features, versions, initiating scanning states, parsing out scanning results, managing connections, etc.
