42.4.3 Bluetooth Low Energy Advertisement Controller

Bluetooth Low Energy advertisement controller is a hardware controller that supports offloading of Bluetooth 5.2 advertisements. This is a simpler advertising scenario requiring much smaller memory.

The task controller manages overall TX/RX functionality and starts TX control FSM / RX control FSM in the baseband as per requirement to transmit/receive a packet. The task controller also manages the coexistence interface with Wi-Fi. The task controller can also be used directly by the firmware to measure the RSSI across various Bluetooth channels, which can, then, be used to generate an AFH channel map.
