Functional Description
Bluetooth Baseband Core
The Bluetooth Baseband Core (BBC) implements all of the time-critical functions required for high-performance Bluetooth operation.
The BBC manages the buffering, segmentation, and routing of data for all connections. It also buffers data that passes through it,
handles data flow control, schedules ACL and TX/RX transactions, monitors Bluetooth slot usage, optimally segments and packages
data into baseband packets, manages connection status indicators, and composes and decodes HCI packets. In addition to these
functions, it independently handles HCI event types, and HCI command types.
Link Control Layer
The link control layer is part of the Bluetooth link control functions that are implemented in dedicated logic in the link control unit (LCU).
This layer consists of the command controller that takes commands from the software, and other controllers that are activated or
configured by the command controller, to perform the link control tasks. Each task is performed in a different state or substate in the
Bluetooth Link Controller.

Advertising
Scanning
