PROBLEM TO BE SOLVED: To provide a Bluetooth (R) apparatus which is capable of saving electric power when data communication is not maintained, establishing a link in a shorter time, and protecting a logic link against disconnection near a critical communication range in which communication can be maintained. SOLUTION: A Bluetooth (R) apparatus 11 is composed of a radio communication unit 12 which makes radio communication, a link control unit 13 which controls the connection/cutoff of a physical link for the radio communication unit 12, and an application unit 14 which includes the upper layer of a Bluetooth (R) protocol stack and a man-machine interface. The link control unit 13 makes the radio communication unit 12 cut off the physical link and the application unit 14 hold a logic link when the data communication is not maintained. |
