PROBLEM TO BE SOLVED: To provide a short-range wireless communication device capable of improving the responsiveness of communication.SOLUTION: A vehicle 1 and an electronic key 2 perform collation communication to confirm whether the electronic key 2 is right or not upon establishing a link by Bluetooth communication. At this time, a connection interval T, i.e. a repetition interval of calling from the electronic key 2 to the vehicle 1 is set to a shorter "Ta." After collation establishment is confirmed in collation communication, regular communication is performed between the vehicle 1 and the electronic key 2, and the connection interval T at this time is set to a longer "Tb(>Ta)."SELECTED DRAWING: Figure 3

    【課題】通信の応答性を向上することができる近距離無線通信装置を提供する。【解決手段】車両1及び電子キー2は、ブルートゥース通信のリンクが確立すると、電子キー2の正否を確認する照合通信を実行する。このとき、電子キー2から車両1への呼び掛けの繰り返し間隔である接続インターバルTは、短めの「Ta」に設定される。照合通信において照合成立が確認されると、続いて車両1及び電子キー2の間で定期通信が実行されるが、このときの接続インターバルTは、長めの「Tb(>Ta)」に設定される。【選択図】図3
