Therefore, as shown in FIG. 7, a flexible RSSI value authentication method Can be adopted.

That is, in the present invention, when the measured values are basically the same,

Even if the RSSI value of the current master Bluetooth 400 measured by the slave Bluetooth 300 is equal to the value that was authenticated in the past, it can be regarded as the authentication success.

      In addition, the RSSI values that have been authenticated in the past are summed and divided into a sum, and an average value is derived. Even if the derived average value is equal to the currently received RSSI value, it can be regarded as authentication success.

In this series of processes, the present invention refers to a case where authentication is considered to be successful or inconsistent with the determination result of the RSSI value through a series of steps as shown in FIG. 6, and through the dead bolt drive operation step, Is transmitted to the smartphone 401 equipped with the master Bluetooth 400 and the state of the door opened in the application of the smartphone 401 is displayed as a character or figure so that the user of the smartphone 401 confirms the door opened state 7, if the RSSI value is not equal to or equal to the previous RSSI value or is not equal to the average value, the RSSI value determination result is not authenticated. Therefore, the deadbolt motor 803 is not operated, The door opening completion status signal is not transmitted from the slave Bluetooth device 300 to the master Bluetooth device 400. Therefore, at this time, a character or a picture corresponding to the door open failure is displayed in the application of the smart phone 401 carried by the user. At this time, when the user inputs a number inputted as an emergency opening number at the time of installing the application for opening the door, ) Receives the emergency opening number, and if the emergency opening number is the same as that input in the initialization process, executes the deadbolt driving operation in the same manner as in the case of authenticating the RSSI value determination and transmits the door opening completion status to the master Bluetooth 400 The state of the completed text is displayed as a character or a picture in the same manner as in the case of the normal authentication based on the RSSI value.
