IV. Bluetooth Architecture Components of Bluetooth Architecture (e.g., Bluetooth modules, profiles) Bluetooth architecture consists of various components that enable communication between devices and define their functionalities. Bluetooth Modules: Physical components embedded in devices to enable Bluetooth connectivity. These modules integrate Bluetooth hardware and software components, providing a standardized interface for device manufacturers to incorporate Bluetooth technology into their products. Bluetooth Profiles: Specifications defining the functions and protocols that Bluetooth-enabled devices must support to communicate with each other. Examples include the Hands-Free Profile (HFP) for wireless headphones and the Advanced Audio Distribution Profile (A2DP) for streaming audio. Device Roles: Master, Slave, and Peer-to-Peer Connections In Bluetooth communication, devices assume different roles based on their capabilities and requirements. Master: A device that initiates and controls the connect
