Feature: Bluetooth 3.0 + High Speed (HS) Support
Description: The driver enables the AR5BBU12 module to utilize the Bluetooth Core Specification Version 3.0 + HS. This is a significant feature because it allows the Bluetooth controller to utilize the device's 802.11 (Wi-Fi) radio to achieve data transfer speeds of up to 24 Mbit/s.
This is a substantial upgrade over standard Bluetooth 2.0/2.1 modules (which are capped at 2.1 Mbit/s), allowing for faster file transfers and improved audio streaming bandwidth while maintaining lower power consumption when idle. The driver acts as the critical bridge that manages the alternating use of the Wi-Fi radio for these high-speed Bluetooth data bursts.
