  First, when a user designates a connection model of a device to be connected via short-range wireless communication and operates a connection setting SW (connection setting switch), the navigation device 20 detects an operation of the connection setting SW in the process of step S11. Then, the switch designated from the operation unit 24 is detected.

  Then, the navigation device reads the two-dimensional code corresponding to the corresponding model from the recognition image data storage unit 28 and displays it on the display unit 25 in the process of step S12. The two-dimensional code displayed here is a two-dimensional code obtained by converting the ID corresponding to the connected model, the user ID, and the connection authentication code as described above.

  When the two-dimensional code is displayed on the display unit 25, the mobile phone 10 images the two-dimensional code displayed on the display unit 25 of the navigation device 20 by the imaging unit 13 in the process of step S21 in the flowchart shown in FIG. . In step S22, it is determined whether the captured image is a photographed image or a two-dimensional code for connection setting.

  If the captured image is not a two-dimensional code for connection setting, it is displayed in step S29 that a connection setting error has occurred, and the process is terminated. If it is a two-dimensional code, the process proceeds to step S23, the connection setting function is turned on, the two-dimensional code is decoded, and an authentication code or the like is stored (set) in the data storage unit 18.

  The processing for setting the connection between the navigation device 20 and the mobile phone 10 is completed by the processing so far.

  Thereafter, returning to the flowchart of FIG. 2, the navigation device 20 sends an authentication code message to the connected device in the process of step S13, and starts a timer in the process of step S14. This process is a process for timing out and ending the process when there is no response to the authentication message from the mobile phone 10 within a predetermined time.

  When the timer is started in the process of step S14, reception of a response message to the authentication message from the mobile phone 10 is monitored in the process of step S15. If a response message is received by the process of step S15, connection will be made in the process of step S19 and communication will be started.

  If no response message is received in the process of step S15, the count value of the timer is checked in the process of step S16 to determine whether a time-out has occurred. If not timed out, the process returns to step S15 to wait for reception of a response message. If it is time-out, the process proceeds to step S17, the sending of the authentication message is stopped, and in step S18, a connection error is displayed and the process is terminated.

  On the other hand, when the mobile phone 10 requests connection to the navigation device 20, an authentication message is transmitted to the navigation device 20 based on the authentication data stored in the data storage unit 18 in the process of step S24 in the flowchart of FIG. A timer is started in the process of S25. This process is a process for timing out and ending the process when there is no response to the authentication message from the navigation device 20 within a predetermined time.

  When the timer is started in the process of step S25, reception of a response message to the authentication message from the navigation device 20 is monitored in the process of step S26. If a response message is received by the process of step S26, connection will be made in the process of step S30 and communication will be started.

  If no response message has been received in the process of step S26, the count value of the timer is checked in the process of step S27 to determine whether a timeout has occurred. If not timed out, the process returns to step S26 to wait for reception of a response message. If it is time-out, the process proceeds to step S28, the sending of the authentication message is stopped, and in step S29, a connection error is displayed and the process is terminated.

  In the above embodiment, the image data for authentication is captured at the time of connection setting. In the following, an example in which mutual authentication is performed based on a connection authentication request has been described. However, the present invention is not limited to such an embodiment. You may comprise.
