BLUETOOTH MASTER WITH IMPROVED TRANSMITTING EFFICIENCY AND DATA TRANSMITTING METHOD USING THE SAME

摘要

A Bluetooth master for improving transmission efficiency and a data transmission method using the master are provided to add information on a slave apparatus to data to send the data to a receiving target slave apparatus only, thereby improving transmission efficiency even without changing communication regulations between the Bluetooth master and the slave. An interface unit(230) relays communication with an external apparatus. A storage(210) stores a type of data received through the interface unit and receiving target slave apparatus information corresponding to the type of the data. If predetermined data is received from the external apparatus, a controller(220) transmits the received data to a receiving target slave apparatus by using the type of the received data and the information corresponding to the received data.
