How the bluetooth internally used in mobile?

Bluetooth in a mobile device works internally through a combination of hardware and software. The Bluetooth chip acts as a radio transmitter and receiver, enabling wireless communication with other devices. The device's operating system manages connections via a protocol stack, allowing functions like file sharing, audio streaming, and connecting to accessories. The internal architecture includes a controller for radio operations and a host for managing data and user applications, all working together for seamless wireless connectivity.
