PURPOSE: An electronic blackboard system using a bluetooth and a method for processing data thereof are provided to transmit data and a voice by wireless using a bluetooth which is a local area wireless communication and to supply prepared note information and voice information on an electronic blackboard in real time without changing hardware and software by performing a porting of a host part of the bluetooth to a microprocessor for a compatibility with conventional electronic blackboards. CONSTITUTION: An electronic blackboard(201) writes transmission contents by an electronic blackboard pen. A coordinate calculator(202) converts note contents of the electronic blackboard(201) into coordinate data. A UART(Universal Asynchronous Receiver and Transmitter,203) transmits the coordinate data to a bluetooth module. A transmission bluetooth module(204) transmits the coordinate data and voice data inputted through a mike(205) by wireless. A receipt bluetooth module(206) receives the coordinate data and the voice data being transmitted from the transmission bluetooth module(204) and inputs the data in a UART(207) and a sound card(208). The UART(207) inputs the coordinate data being output from the receipt bluetooth module(206) to a computer(209). The sound card(208) inputs the voice information being output from the receipt bluetooth module(206) to the computer(209). The computer(209) receives and stores the coordinate data and voice data, displays the coordinate data, and outputs the voice data.
