Host Controller Interface

The Host Controller Interface (HCI) provides a command interface to the baseband controller and link manager and allows access to the hardware status and control registers. This interface provides a uniform method for accessing the hardware Bluetooth capabilities.

The HCI usually consists of three entities:

• The actual Bluetooth hardware device, which is often called the Host Controller. In addition, this device also contains the HCI firmware that implements the HCI commands.

• The HCI driver is the involved software entity. It is capable of sending commands to the firmware and receiving events that occur in the Host Controller.

• To connect the firmware in the Host Controller and the HCI driver together, a transport layer is needed. Both can be connected over various transport protocols, but nowadays the Host Controller is usually connected over the USB.
