Bluetooth Baseband Core
The Bluetooth Baseband Core (BBC) implements all time-critical functions required for high-performance Bluetooth operation. The
BBC manages the buffering, segmentation, and routing of data for all connections. It prioritizes and schedules all RX/TX activities
including adv, paging, scanning, and servicing of connections. In addition to these functions, it independently handles the host
controller interface (HCI) including all commands, events, and data flowing over HCI. The core also handles symbol timing, forward
error correction (FEC), header error control (HEC), cyclic redundancy check (CRC), authentication, data encryption/decryption, and
data whitening/dewhitening.
