    Abstract: A Bluetooth communication method and system allows a Bluetooth device to rapidly establish a Bluetooth connection. A first Bluetooth device that is in a client mode displays a visual representation of its ID on a display unit. A second Bluetooth device that is in a host mode acquires the displayed visual representation of the ID of the first Bluetooth device via a camera module and extracts the ID of the first Bluetooth device. The second Bluetooth device transmits a Bluetooth communication-connection-request signal to the first Bluetooth device using the extracted ID. The first Bluetooth device transmits a replay signal responding to the Bluetooth communication-connection-request signal to the second Bluetooth device. The second Bluetooth device receives the reply signal and establishes a Bluetooth communication channel with the first Bluetooth device.
