摘要： A method for communication link connection in a data transmission between devices using visible light communication (VLC) that can provide a visible indication prior to establishing a communication link between the devices. The method includes activating a VLC mode by a first VLC apparatus in order to transmit the data; scanning other apparatuses to establish a communication link with a second VLC apparatus; requesting a communication link to the second VLC apparatus in order to transmit the data; and receiving a response, indicating whether data can be received from the second VLC apparatus, and establishing communication link connection. A user can easily recognize the visual indication before the establishment of the communication link, providing an opportunity for the user to arrange the apparatus for optimal communication distance/angle from another device, and for a status of the communication.
