WIRELESS COMMUNICATION SYSTEM AND COMMUNICATION METHOD USING THE SAME

PROBLEM TO BE SOLVED: To provide a wireless communication system and communication method using the system capable of implementing wireless communication connection while easily performing pairing of devices including a portable terminal device transmitting an RDA and having high security, in the case of performing connection control using Bluetooth communication between a master device and a slave device.SOLUTION: When power of an LED lighting fixture 20 is turned ON, a PDA and D/N are transmitted. After that, when remote controller operation or remote-controlled operation is performed, an S/ID is transmitted in addition to the PDA and D/N only during a period predetermined for the LED lighting fixture 20. A portable terminal device 1 stores the S/ID and performs pairing. The portable terminal device 1's transmission of at least the D/N, the S/ID, and U/D-A enables the portable terminal device 1 to perform various operation/control for the LED lighting fixture 20 by communicating with the lighting fixture. 【課題】マスタ装置とスレーブ装置との間でBluetooth 通信で接続制御を行う場合、無線通信接続を、ＲＤＡを送信する携帯端末装置も含めて、容易にペアリングでき、かつ高いセキュリティを持って実現することができる無線通信システムおよび該システムを用いた通信方法を提供する。【解決手段】ＬＥＤ照明器具２０の電源ＯＮによりＰＤＡとＤ／Ｎが送信され、リモコン操作またはプルレス操作がなされると、所定の時間だけ上記データの他にＳ／ＩＤも発信する。携帯端末装置１はＳ／ＩＤを保存し、ペアリングを行う。携帯端末装置１は少なくともＤ／Ｎ，Ｓ／ＩＤおよびＵ／Ｄ−Ａを送ることにより、ＬＥＤ照明器具２０との間で照明器具に対する種々の操作・制御が可能になる。【選択図】図１Ａ
