The host controller interface (HCI) provides a uniform interface method for accessing Bluetooth hardware capabilities.
During the initialization sequence, the HCI creates read and write threads, establishes a connection to the Bluetooth transport, and performs a reset and read of device buffer sizes. It then enters an initialized state and is ready to accept clients.
