[About creating SSID list]
FIG. 2 is a diagram schematically showing a Wi-Fi beacon. The Wi-Fi beacon is defined by the Wi-Fi standard, and the SSID is described as one item of network information in the part where the information according to the determined format is described. The access point 30 periodically broadcasts a Wi-Fi beacon. The Wi-Fi communication unit 13 receives the Wi-Fi beacon broadcast from the access point 30.

The device control unit 11a acquires the SSID included in the Wi-Fi beacon received by the Wi-Fi communication unit 13 from the Wi-Fi communication unit 13. The device control unit 11a describes the SSID acquired from the Wi-Fi communication unit 13 in the SSID list 11b. At this time, if the SSID acquired from the Wi-Fi communication unit 13 is already included in the SSID list 11b, the same SSID is not duplicated in the SSID list 11b. FIG. 3 shows a configuration example of the SSID list according to the present embodiment. The SSID values exemplified in FIG. 3 are values for convenience.

The device control unit 11a controls the Wi-Fi communication unit 13, receives the Wi-Fi beacon at regular intervals, and updates the SSID list 11b based on the reception result of the Wi-Fi beacon. As a result, the SSID list 11b is updated at regular intervals.

Among the access points 30, there may be a so-called "stealth AP (stealth access point)" in which the SSID value is NULL or the SSID length is 0. The following two examples can be mentioned as the SSID included in the Wi-Fi beacon broadcast from the stealth AP.

(Example 1 of SSID of stealth AP)
When the SSID value is NULL, for example, when the SSID length is 4 (SSID Length = 4), the SSID value is NULL (¥ 0) by the length of the SSID (SSID ='¥ 0). ¥ 0 ¥ 0 ¥ 0').

(Stealth AP SSID Example 2)
When the SSID length is 0 (SSID Length = 0), "SSID =''" as the SSID value.

In the device control unit 11a, the SSID acquired from the Wi-Fi communication unit 13 is Example 1 of the SSID of the above-mentioned stealth AP (the value of the SSID is FULL) or Example 2 of the SSID of the above-mentioned stealth AP (the length of the SSID is 0). ), And if applicable, “SSID value is FULL” or “SSID length is 0” is described in the SSID list 11b as the SSID. In the present embodiment, "the value of SSID is NULL" or "the length of SSID is 0" described in the SSID list 11b corresponds to the stealth access point information.

[System operation]
The operation of the system 1 according to the present embodiment will be described with reference to FIGS. 4 to 7. 4 to 7 are sequence charts for explaining the operation of the system 1 according to the present embodiment. In FIGS. 4 to 7, AP refers to the access point 30, PR refers to the printing device 10, and TE refers to the terminal device 20.

First, in FIG. 4, in the terminal device 20, the processing unit 21 executes an application, and the function of the terminal control unit 21a is realized. Further, in the terminal device 20, the BLE communication unit 22 is activated under the control of the terminal control unit 11b. Further, the SSID and password of the access point 30 are not set in the printing device 10.

(Step S101) The power of the printing device 10 is turned on. When the power of the printing device 10 is turned on, the processing unit 11 executes the firmware recorded in the memory, and the function of the device control unit 11a is realized.

(Step S102) The device control unit 11a controls the Wi-Fi communication unit 23, receives the Wi-Fi beacon, and creates the SSID list 11b based on the reception result of the Wi-Fi beacon. The device control unit 11a stores the created SSID list 11b in the memory.

(Step S103) The device control unit 11a controls the BLE communication unit 12 to transmit an advertising packet as a BLE standard beacon signal.

(Step S104) In the terminal device 20, when the terminal control unit 21a receives the advertisement packet by the BLE communication unit 22, the touch panel display 24 displays a screen of "notification asking whether to connect to the printing device via wireless LAN". When the user accepts the operation of "approving the wireless LAN connection with the printing device" by the touch panel display 24, the terminal control unit 21a selects the printing device 10 as the partner for establishing the first wireless communication 110. After that, the process proceeds to step S105.

If there are a plurality of printing devices 10 that transmit advertisement packets, step S104a (steps S104a-1 and S104a-2) is executed.

(Step S104a-1) When the terminal control unit 21a detects that there are a plurality of printing devices 10 that receive a plurality of advertisement packets by the BLE communication unit 22 and transmit the advertisement packets, a list of the printing devices 10 is displayed on the touch panel display 24. Display the screen of. The list of printing devices 10 shows the printing devices 10 in order of increasing distance from the terminal device 20.

Here, a method of calculating the distance between the terminal device 20 and the printing device 10 will be described. The terminal control unit 21a acquires the received signal strength (RSSI: Received Signal Strength Indication) of the BLE standard beacon signal by the BLE communication unit 22. The terminal control unit 21a obtains the distance from the printing device 10 based on the received signal strength of the BLE standard beacon signal acquired by the BLE communication unit 22. The terminal control unit 21a compares the signal strength value as a reference of the distance included in the BLE standard beacon signal with the received signal strength of the BLE standard beacon signal. The signal strength value that serves as a reference for the distance is the BLE standard beacon signal at the receiving side device when the receiving side device is installed at a position that is a reference distance away from the transmitting side device of the BLE standard beacon signal. Received signal strength. In the example of using the advertisement packet as the beacon signal of the BLE standard, the transmitting side device is a broadcaster and the receiving side device is an observer (Observer). The reference distance is, for example, 1 m, but may be set to a different distance.

The explanation is returned to FIG.
(Step S104a-2) When the terminal control unit 21a receives an operation of selecting one printing device 10 from the list of printing devices 10 by the touch panel display 24, the terminal control unit 21a transfers the selected printing device 10 to the first wireless communication 110. Select as the person to establish. After that, the process proceeds to step S105.

(Step S105) The terminal control unit 21a controls the BLE communication unit 22 and establishes the printing device 10 and the first wireless communication 110 selected as the partner for establishing the first wireless communication 110.

(Step S106) The terminal control unit 21a transmits the message “XXXX” to the printing device 10 via the first wireless communication 110. The message "XXXX" is generated according to a predetermined rule between the application of the terminal device 20 and the firmware of the printing device 10.

(Step S107) In the printing device 10, the device control unit 11a determines whether or not the message “XXXX” received from the terminal device 20 via the first wireless communication 110 is correct. Whether or not the message "XXXX" is correct is determined according to a predetermined rule between the application of the terminal device 20 and the firmware of the printing device 10. When the device control unit 11a determines that the message "XXXX" is correct, the device control unit 11a responds the message "YYYY" to the terminal device 20 via the first wireless communication 110. The message "YYYY" is generated according to a predetermined rule between the application of the terminal device 20 and the firmware of the printing device 10.

In the terminal device 20, the terminal control unit 21a determines whether or not the message "YYYY" received from the printing device 10 via the first wireless communication 110 is correct. Whether or not the message "YYYY" is correct is determined according to a predetermined rule between the application of the terminal device 20 and the firmware of the printing device 10. When the terminal control unit 21a determines that the message "YYYY" is correct, it determines that information is exchanged with the printing device 10 via the first wireless communication 110. On the other hand, when the terminal control unit 21a determines that the message "YYYY" is incorrect, it determines that the information is not exchanged with the printing device 10 via the first wireless communication 110.

The procedure of steps S106 and S107 may be reversed. First, the printing device 10 transmits the message "XXXX" to the terminal device 20, and when the terminal device 20 determines that the message "XXXX" is correct, the terminal device 20 responds to the printing device 10 with the message "YYYY". In the printing device 10, if the device control unit 11a determines that the message "YYYY" is correct, it determines that information is exchanged with the terminal device 20 via the first wireless communication 110. On the other hand, when the device control unit 11a determines that the message "YYYY" is incorrect, it determines that the information is not exchanged with the terminal device 20 via the first wireless communication 110.

Here, as a result of the above steps S106 and S107, it is assumed that the terminal device 20 and the printing device 10 exchange information via the first wireless communication 110.
