HANDS-FREE BLUETOOTH CAR SYSTEM

摘要

A hands-free Bluetooth system is described. The Bluetooth system comprises a base unit and a controller unit. The controller includes a built-in speaker, a built-in microphone and a control button configured to receive an action from a user and transmit a signal which corresponds to the action to the base unit. The controller unit automatically pairs through Bluetooth to the base unit and directs audio signals received from the base unit to the built-in speaker. The base unit pairs through Bluetooth to a smartphone. The base connects to an audio system through an audio connection. Upon receiving a signal for an incoming call through the smartphone, the base unit tests whether it is connected to the speaker of the audio system. If it is connected, the base unit directs the incoming call to the audio system. However, if it is not connected, the base unit directs the incoming call to the controller.
