[0027] In addition to the configurations shown in the drawings, the electronic device 2 and the electronic device 3 may also have other functions to realize the functions of each device. For example, a printer has a configuration for printing. A scanner has a configuration for reading an image.

[0028] While the electronic device 2 and the electronic device 3 are both powered on, the NFC-IF 241 Or, NFC-IF341 periodically transmits a signal to communicate with the user via wireless communication using the NFC method. For example, when the NFC function is enabled, The information processing terminal 1 is within a predetermined distance range of the NFC-IF241 or the NFC-IF341.

It is equipped with Wi-Fi Direct (hereinafter referred to as "WFD") type wireless communication. That is, the electronic device 2 and the electronic device 3 each store connection information in the WFD format. The group owner device remembers the group ID and manages the network. The WFD method has the function of building a network with the NFC device. The communication method is different, and it has a wider communication range and faster communication speed than the NFC method.

[0030] Specifically, the electronic device 2 and the electronic device 3 communicate with each other by wireless communication using, for example, the NFC method. When the connection becomes possible, the WFD connection information of the own device is transmitted by the NFC method. When the management terminal 1 receives the WFD connection information via the NFC method, the wireless LAN 42, the device becomes a client device by transmitting the received WFD connection information.

[0033] In this embodiment, the electronic device 2 has already acquired the connection information of the access point 4. The setup to connect to the access point 4 is complete. The electronic device 2 On the other hand, the electronic device 3 is an example of a first electronic device. The electronic device 3 does not have the connection information and the setup is not completed. This is an example of a device.

[0034] The wireless network using access point 4 is a highly secure wireless network. However, in the vicinity of the electronic device 3, there are access points connected to a low-security wireless network. However, there may be other access points other than access point 4. It is not desirable to connect the electronic device 3 to the information processing terminal 1. The setup to connect to the computer 4 may or may not be completed. Terminal 1 has completed the setup to connect to an access point other than access point 4. It's fine if it is.

[0035] Next, in the communication system 100 of this embodiment, the electronic device 3 is connected to the access point 4 Sequence diagrams and flows for the various steps to complete the setup to connect to The procedure of this embodiment will be described with reference to the chart. For example, This is executed when a new electronic device 3 is added to the wireless network. In the sequence diagram, the processing of the information processing terminal 1 is executed by the CPU 11, and the processing of the electronic device 2 is executed by the CPU 12. The processing of the electronic device 3 is executed by a CPU 21 , and the processing of the electronic device 3 is executed by a CPU 31 .

[0036] A new electronic device 3 is added to a wireless network using an access point 4. In this case, the user operates the information processing terminal 1 to start the information transmission application 121 and The user takes a picture including the connection information of the point 4 with the camera 15. An image including connection information 222 of the access point 4 is displayed on the user interface 23 of the electronic device 2. The image may be photographed or printed on a label attached to the access point 4. Alternatively, an image including the connection information 41 stored in the camera may be captured.

[0037] First, set up a new electronic device 3 using the already set up electronic device 2. The procedure for updating the electronic device 2 will be described with reference to the sequence diagram of FIG. A device connected to a wireless network via an access point 4. In this procedure, it is assumed that information processing terminal 1 is not connected to access point 4.

[0038] The information processing terminal 1 accepts a start instruction from a user and starts the information transmission application 121. When the user inputs the information (A01), the information processing terminal 1 transmits a display instruction to the electronic device 2 (A02). The terminal 1 judges whether the device information 123 is stored in the memory 12 and If the electronic device is set up, the device information 123 is read out. The information processing terminal 1 acquires information on the electronic device 2 for which the setup has been completed. A message prompting the user to hold the information processing terminal 1 over the user interface 13 is displayed on the user interface 13. When the electronic device 2 is connected to the electronic device 2 via NFC, a frame indicating a display instruction is displayed on the electronic device 2. After transmitting the command, the information processing terminal 1 disconnects the connection with the electronic device 2. do.

[0039] The information processing terminal 1 displays a message urging the user to hold the information processing terminal 1 over the electronic device 2. Instead of displaying the message, the user operates the electronic device 2 that has been set up. A message prompting the user to input a display command to display the connection information 222 is sent to the user interface 13. In this case, the information processing terminal 1 transmits a display instruction to the electronic device 2. Without this, the electronic device 2 receives a user instruction to display the connection information 222 via the user IF 23. Input may be accepted.

[0040] When the electronic device 2 receives the display instruction, it starts the image display application 221 and stores the image in the memory. 12 and generates an image including the connection information 222. The electronic device 2 encrypts the connection information 222 (A03) and transmits the encrypted connection information A two-dimensional code including the encrypted information and the user's own device information is generated, and the generated two-dimensional code is An image of the card is displayed on the user IF 23 (A04). A04 is an example of the display process. The two-dimensional code may be a QR code or a unique code that can be analyzed by the information transmission application 121. The code may be:

[0041] After transmitting the display instruction, the information processing terminal 1 activates the camera 15 (A05). Before the camera 15 is started, the information processing terminal 1 may, for example, A message prompting the user to take a picture of the 3D code is displayed on the user IF 13. Before starting the camera 15, a start instruction from the user may be accepted.

[0042] When the user operates the shooting button (A06), the information processing terminal 1 In A06, the user executes the process of acquiring the image data of the electronic device 2 (A07). The two-dimensional code displayed on the user interface 23 is photographed by the camera 15 of the information processing terminal 1. In this way, the information processing terminal 1 obtains the image data of the two-dimensional code. The processing terminal 1 receives an instruction from the user to check or retake an image before A07. is also good.

[0043] Furthermore, the information processing terminal 1 analyzes the image of the acquired image data (A08 ), and obtains device information and encryption information. A08 is an example of an obtaining process. The information processing terminal 1 adds the device information stored in the memory 12 to the information acquired in A08. In this procedure, the electronic device 2 determines whether the set information 123 is included. The setup is complete, and the device information 123 contains the device information of the electronic device 2. Therefore, the information processing terminal 1 adds the information acquired in A08 to the information stored in the memory 12. The device information 123 stored in the memory is included (A09). This is an example of a judgment process. A09 judges that there is an electronic device whose setup is complete. This is the procedure to determine whether

[0044] The information acquired from the image captured by the camera 15 includes device information of the electronic device 2. In rare cases, it is determined that the device information of the electronic device 2 is included in the device information 123. Then, the information processing terminal 1 executes a setup procedure for setting up the electronic device 3. Get started.

[0045] The information processing terminal 1 displays a message urging the user to hold the information processing terminal 1 over the NFC-IF 341 of the electronic device 3. The user then displays the message on the user IF 13, and the information processing terminal 1 is connected to the electronic device 3 by the user. When the information processing terminal 1 and the electronic device 3 are held up to each other (U01), wireless communication is performed using the NFC method between the information processing terminal 1 and the electronic device 3. The information processing terminal 1 receives the wireless communication from the electronic device 3 via the NFC-IF 141. The FD connection information is received, and a WFD connection is requested to the electronic device 3. This enables wireless communication in the WFD system between the information processing terminal 1 and the electronic device 3 ( U02).

[0046] The information processing terminal 1 starts the setup application 321 of the electronic device 3 in the WFD method. The electronic device 3 starts the setup application 321 ( The information processing terminal 1 transmits information indicating that the startup has been completed (U05). After receiving the completion information, the information processing terminal 1 notifies the electronic device 3 of the connection of the access point 4. The electronic device 3 transmits information including the follow-up information to the information processing terminal 1 at U06. The process U06 is an example of a transmission process, and the process U07 is an example of a reception process. It is.

[0047] In this procedure, the information processing terminal 1 receives the connection information encrypted by the electronic device 2. Since the encryption information was obtained by image analysis of A08, U06 The electronic device 3 receives the connection information and transmits the connection information to the electronic device 3. Since the received information is encrypted, the encrypted information is decrypted and the connection information 222 is obtained. For example, if electronic device 2 and electronic device 3 are devices of the same series, If so, the electronic device 2 has a common encryption function and encrypts the connection information 222. The electronic device 3 can decrypt the encrypted information. The processing terminal 1 cannot decrypt the encrypted information and cannot use it, so the security of the connection information is not guaranteed. do.

[0048] The electronic device 3 transmits the acquired connection information 222 to the access point 4 and sets up The setup process is completed (U07). U07 is an example of the setup process. When sending encrypted information in U07, the management terminal 1 sends the command to decrypt and set up The access point 4 that has received the connection information 222 also transmits the IP address to the electronic device 3. The IP address is assigned to the electronic device 3 and the IP address information is transmitted to the electronic device 3 (U08). The electronic device 3 that has received the P address information indicates that the setup is complete. A completion notification including device information of the own device is transmitted to the information processing terminal 1 (U0 9). U09 is an example of a setup result transmission process. Setup is complete. Then, the connection information 322 is stored in the memory 32 of the electronic device 3 .

[0049] When the information processing terminal 1 receives the completion notification, the information processing terminal 1 The device information indicating the electronic device 3 that has completed the setup is The information processing terminal 1 then stores the information in the WFD 123 (U10). Then, the connection between the electronic device 2 and the power supply 1 is cut off (U11). The child device 3 is connected to the same access point 4. There is no need for the terminal 1 to be connected to the access point 4 .

[0050] After the setup procedures U01 to U11, the information processing terminal 1 The data is deleted (A20), and the information transmission application 121 is terminated (A21). The child device 2 ends the image display application 221 that was started in response to the instruction from the A02, and The device 3 ends the setup application 321 started in U04. The processing terminal 1 may transmit a termination instruction to each of the electronic devices 2 and 3, or the user may instruct the electronic devices 2 and 3 to terminate the processing. It can be set to terminate when a command is received, or when a certain time has elapsed since launch. You can do that.

[0051] In this way, the second electronic device that has already been set up can receive the secondary data containing the connection information. By displaying the original code and including device information in the two-dimensional code, The terminal 1 can obtain the connection information and device information simply by reading the two-dimensional code. Furthermore, the information processing terminal 1 receives the device information 123 and displays the two-dimensional code. You can confirm that the device is electronic device 2, which has already been set up. The wireless network to which the electronic device 2 is connected is a highly secure wireless Since it can be assumed that the network is a wired network, the security of the connection information is guaranteed. Even if the user of the information processing terminal 1 does not know the location or connection information of the access point 4, An electronic device 3 can be connected.

[0052] Next, it is determined that device information 123 is included at A09 in the sequence diagram of Figure 2. If the electronic device 3 is not installed, the procedure for setting up a new electronic device 3 is as shown in FIG. For example, if the information acquired in A08 includes device information, If there is no device, or if the device information included in the information acquired in A08 is If it is not included in 123, in the sequence diagram of Figure 2, A09, the setup It is not possible to determine whether there is an electronic device that has already been set up. Electronic device 2 is not available, electronic device 2 cannot be used, electronic device 2 is occupied by other processes In the state where the electronic device 2 has the 2D code, the electronic device 2 cannot display the 2D code. Therefore, the steps in the sequence diagram in Figure 2 cannot be executed.

[0053] If the user is unable to display the two-dimensional code on the electronic device 2, the user may Instead, the procedure shown in FIG. 4 is executed in the communication system shown in FIG. At 100, a step of setting up a new electronic device 3 without using the electronic device 2. In FIG. 4, the same steps as those in FIG. 2 are denoted by the same reference numerals and will be described in the same order. Omitted.

[0054] When the information transmission application 121 is started (A01), the information processing terminal 1 stores the data in the memory 12. Determine whether the device information 123 is stored. If the device 2 is not present, it is determined that the device information 123 is not stored. Even if the electronic device information 123 is stored, if the electronic device 2 cannot be used, the information The processing terminal 1 sends an instruction to the user IF 13 to set up without using the electronic device 2. If a negative determination is made in A09 of FIG. 2, the information processing terminal 1 may accept the request. A message will be displayed saying that the scanned 2D code does not contain device information. An instruction to set up without using the electronic device 2 is received at the user IF 13. Good too.

[0055] The information processing terminal 1 displays a message on the user IF 13 prompting the user to photograph the connection information 41, The camera 15 is started (A05). In A05, the information processing terminal 1 A message will appear prompting you to take a picture of the label containing the connection information for point 4. That's fine.

[0056] When the user operates the shooting button (A06), the information processing terminal 1 In this procedure, the user performs the connection of the access point 4 and obtains the image data. Since the information 41 is photographed, the information processing terminal 1 receives the connection information 41 of the access point 4. Image data of an image is acquired (B01).

[0057] When the image of the connection information is acquired, the information processing terminal 1 analyzes the acquired image (B02), The connection information is acquired. B02 is an example of an acquisition process. If the image is a QR code, the information contained in the QR code is read and the connection information 41 is extracted. If the captured image is a text image, the character recognition function is used to obtain the connection information 41. The connection information 41 is automatically read from the image captured by the camera 15, and the user can input the connection information 41. The information processing terminal 1 can easily obtain the connection information 41 without having to input the image. If the image is a character image, the user is asked whether the character recognition result is correct or not. It would be good to accept suggestions for correction.

[0058] Then, the information processing terminal 1 adds the information acquired at B02 to the information stored in the memory 12. Determine whether device information 123 is included. This determination is the same as A09 in FIG. 2. The image captured by the camera 15 is an image of a label or the like of the access point 4. In this case, the information obtained by B02 does not include device information. Also, If there is no electronic device 2 connected to the device, the device information 123 is not stored. Even in this case, the information processing terminal 1 adds the information acquired at B02 to the information stored in the memory 12. It is determined that the device information 123 does not include the device information 123 that has been registered (B03). This is an example of a diagnostic process, and B03 determines that there is no electronic device that has completed setup. This is the procedure.

[0059] After the determination in B03, the information processing terminal 1 selects the access point indicated by the acquired connection information 41. Specifically, the information processing terminal 1 connects the acquired The connection is established after completing the setup using the connection information 41 obtained by the terminal setup. This is an example of a setup process for the information processing terminal 1. 1 can use electronic device 3 via a wireless network. If the setup to B04 has been completed, information processing terminal 1 omits B04.

[0060] Then, the information processing terminal 1 transmits information to the wireless network through the wireless network to which it is connected. The information processing terminal transmits a search signal to search for electronic devices connected to the network (B05). When the terminal 1 is connected to the wireless network to which the electronic device 2 is connected, the electronic device The electronic device 2 receives the search signal transmitted from the information processing terminal 1. In response to the received search signal, the information processing terminal 1 transmits a response signal to the information processing terminal 1 (B06). On the other hand, the electronic device 3 has not yet completed setup and has not received a search signal. Since the device cannot receive the signal, it does not transmit a response signal. You can set up your own wireless network by connecting to the You can easily determine whether or not an electronic device has completed updating.

[0061] The electronic device 2 transmits a signal including its own model information as a response signal. The processing terminal 1 acquires model information from the received response signal (B07). The management terminal 1 refers to the model information 122 stored in association with the information transmission application 121. Then, it is determined whether the received response signal is included in the model information 122 (B08). 8 is an example of the completion determination process.

[0062] The model information included in the received response signal matches the model information included in the model information 122. If it is determined that the information matches ([Match]), the information processing terminal 1 sets up the electronic device 3. The setup procedure starts as shown in Figure 2. The procedure is the same as 1 to 11. It is an electronic device with a pre-stored model. A wireless network with connected electronic devices that have been set up is a secure network. It can be assumed that the wireless network is highly reliable. The response signal indicates that the electronic device 2 is connected. This allows the system to determine whether a wireless network is being used or not, which improves the security of wireless networks. The quality is guaranteed.

[0063] On the other hand, if a response signal to the search signal is not received within a predetermined time, the received response If the model information cannot be obtained from the signal, or if the model information contained in the received response signal is not available, If it is determined that the model information does not match the model information in the model information 122 ([Unknown If the user ID matches the acquired connection information, the information processing terminal 1 sends a confirmation message to the user ID prompting the user to confirm the acquired connection information. The command is displayed on F13 (B09) and instructions input by the user are accepted (B10).

[0064] The confirmation message may include the SSID, password, and OK button, as shown in Figure 5. The information processing terminal 1 includes a confirmation message and a cancel button 131. The user can then determine whether the displayed information is the connection information 41 of the access point 4 to which the connection is to be made. Inquiry, input to either the OK button 131 or the Cancel button 132 is accepted. Then, it is determined whether or not an input to the OK button 131 has been accepted (B 11). B11 is an example of a transmission decision process.

[0065] When it is determined that the input to the OK button 131 has been accepted ([OK]), the information processing terminal 1 starts the setup procedure for setting up the electronic device 3. The steps are the same as steps U01 to U11 in FIG. 2. is an example of permission information indicating permission. This makes it more secure to connect new electronic devices to the wireless network. By asking the user whether or not to send connection information and making them enter it, the connection information is not sent randomly. This can avoid the data being sent to

[0066] On the other hand, when an input to the cancel button 132 on the screen shown in FIG. In this case, the information processing terminal 1 does not set up the electronic device 3, and for example, The information indicating that the operation has been cancelled is displayed on the user IF13 (B12). The input to the input section 132 is an example of permission information indicating non-permission. After U11 or B12, the information processing terminal 1 acquires the image at B01. The image data thus acquired is deleted (A20), and the information transmission application 121 is terminated (A21).

[0067] According to this procedure, the information processing terminal 1 can access the access point 4 simply by reading the label of the access point 4. In addition, the connection information 41 can be obtained by having the user confirm the connection information 41. Since it can be assumed that the wireless network is highly secure, the security of the connection information 41 is guaranteed. Furthermore, according to this procedure, the information processing terminal 1 can identify the wireless network to which it is connected. The search signal is sent via the network, and based on the response signal, the system determines whether to complete the setup. Furthermore, the device will only reject the signal if it receives a response signal from a model that has been previously stored. This completes the setup process, ensuring greater security for the wireless network.

[0068] Next, the procedure of the information transmission process executed by the information processing terminal 1 of this embodiment will be described with reference to FIG. The information transmission process will be described with reference to a flowchart. When the information is transmitted, the information transmission process is executed by the CPU 11 of the information processing terminal 1. This includes each process of the information processing terminal 1 in each sequence diagram described above.

[0069] In the information transmission process, the CPU 11 first starts the camera 15 and takes a picture in response to a user's instruction to take a picture. Upon receiving the command, the CPU 11 acquires image data (A07 or B01, S101). It is determined whether or not the image of the acquired image data includes a two-dimensional code (S102). The object photographed by the user is the QR code on the label of Access Point 4 or the electronic device. If it is a two-dimensional code displayed on chair 2, the image contains the two-dimensional code.

[0070] When it is determined that a two-dimensional code is included (S102: YES), the CPU 11 Connection information is obtained from the dimensional code (S103). For example, access points and wireless networks If the QR code attached to the work instruction manual is photographed, the connection information can be obtained from the image. Furthermore, the CPU 11 determines whether the two-dimensional code includes device information. When the two-dimensional code displayed on the electronic device 2 is photographed, the image shows The device information is included (A09). On the other hand, the QR code of the access point contains the device information. If it is determined that device information is included (S104: If the device information is stored in the device information 123, the CPU 11 It is determined whether or not the

[0071] If it is determined that the acquired image does not contain a two-dimensional code (S102: NO), The PU 11 performs character recognition on the characters contained in the image (S106) and notifies the user of the recognition result. The character recognition is performed by displaying the character on the display unit F13 and accepting corrections from the user (S107). However, if the SSID and password cannot be obtained, the CPU Instead of accepting the correction, an error message may be displayed and the process may be terminated.

[0072] After S107, or if it is determined that the 2D code does not contain device information (S104: NO), or the device information is not stored in the device information 123. If so (S105: NO) (B03), the CPU 11 The device is connected to the wireless network using the acquired connection information (B04), (B05, S1 08).

[0073] Then, the CPU 11 judges whether or not a response signal in response to the search signal has been received (S 109). If it is determined that a response signal has been received (B06, S109: YES), the CPU 1 indicates that the model information included in the response signal matches the model included in the model information 122. It is determined whether or not the battery is turned on (B08, S110).

[0074] If it is determined that a response signal in response to the search signal has not been received (S109: NO), Or, if it is determined that the model does not match the model included in the model information 122 (B08 If the result is "mismatch" at step S110, S110: NO, the CPU 11 sends the confirmation message shown in FIG. The user input is then received by displaying the result on the IF13 (B10, S111). The PU 11 judges whether or not an input to the OK button 131 has been accepted (B11, S11 2).

[0075] When it is determined that an input to the OK button 131 has been accepted ([OK] in B11, S11 2: YES), or it is determined that the model matches the model included in model information 122. (B08 is [Match], S110: YES) or the device information is When it is determined that the information is stored in the information 123 (A09, S105: YES), the CPU 11 , and determine whether the acquired connection information includes both the SSID and password. (S113). For example, the QR code on the label of access point 4 contains the password. Also, if the password for access point 4 has been changed, In this case, the user may choose to include only the SSID. By not obtaining the password and instead prompting the user to enter the password when sending the connection information, This can better ensure the security of connection information.

[0076] If it is determined that the password is not included (S113: NO), the CPU 11 The input screen for accepting input of words is displayed on the user IF 13, and the input of the user is accepted. (S114). After S114, or if it is determined that the password is included ( S113: YES), the CPU 11 transmits connection information including the SSID and password to the electronic device. In step S115, the CPU 11 transmits the In this way, the information processing terminal 1 and the electronic device 3 are connected in the WFD system, and the electronic device 3 After starting up the setup application 321, connection information is transmitted (U01 to U05).

[0077] After transmitting the connection information, the CPU 11 judges whether or not a completion notice has been received (S11 6) If it is determined that a completion notification has been received (U09, S116: YES), the CPU 11 , the device information of the electronic device 3 is stored in the device information 123 (U10, S117). On the other hand, if the cancel button 132 is pressed in the confirmation message displayed in S111, When it is determined that the request has been cancelled (S112: NO), the CPU 11 A message to this effect is displayed on the user IF 13 (S118).

[0078] After S117 or S118, or after the specified time has elapsed, it is determined that the completion notification has not been received. If the image data is not received (S116: NO), the CPU 11 deletes the image data (S119). The transmission process ends.

[0079] As described above in detail, the information processing terminal 1 of the present embodiment uses the access point 4. If you have an electronic device 2 that has completed setup with the wireless network, Since point 4 is assumed to be highly secure, the obtained connection information is sent to electronic device 3. The electronic device 3 is then configured to complete the setup. Without electronic devices2 connected to the network, the security of the wireless network would be insufficient, and the Before transmitting the connection information, the processing terminal 1 determines whether or not to transmit the connection information and transmits it. If the system judges that the information is necessary, it will be sent. If the system judges that the information is not necessary, it will not be sent. This prevents device 3 from randomly connecting to a wireless network access point. This prevents the safety of the electronic device from being compromised.

[0080] It should be noted that the present embodiment is merely an example and does not limit the present invention in any way. Naturally, therefore, the present invention can be modified and changed in various ways without departing from the spirit and scope of the invention. For example, the number of devices constituting the communication system 100 is not limited to the illustrated example, and may be one or more information processing devices. The system may include a management terminal and one or more electronic devices.

[0081] In addition, for example, in the embodiment, the information transmission process including a plurality of steps has been described. It is sufficient to have at least one procedure. Also, it is sufficient to have multiple programs that execute each procedure. It is also possible to realize it as a combined program set.

[0082] Also, for example, in the embodiment, when it is determined that there is no suitable device information (B03 , S104 or S105: NO), send a search signal and check the model information of the response signal Although it is assumed that (B04~B08, S108~S110) should be done, it is not necessary. If it is determined that there is no device information to be used, the information processing terminal 1 displays a confirmation message. (B09, S111), user input may be accepted. Alternatively, If it is determined that there is no information, the information processing terminal 1 displays an error message and You may now exit the pre-processing.

[0083] Also, for example, the confirmation screen accepts instructions to retake the photo in addition to OK and Cancel. When an instruction to retake a photograph is received, the information processing terminal 1 After that, without closing the app, start up the camera 15 again and take a picture.

[0084] For example, the information displayed on the user IF 23 of the electronic device 2 may be a two-dimensional code. It is not limited to this. It can be a one-dimensional code or text information. In that case, the device information 123 may be omitted. The information processing terminal 1 does not judge the device information, and passes the encrypted information to the electronic device 3. In addition, the connection information does not have to be encrypted. However, if the connection information is encrypted and the device If a two-dimensional code including the user's ID and password is displayed, security will be enhanced.

[0085] Also, for example, the response signal does not need to include model information. In that case, the information processing terminal 1 In other words, the information processing terminal 1 does not judge the model of the electronic device that transmits the response signal. If there is an electronic device 3, it may transmit the connection information to the electronic device 3 regardless of its model. In the information transmission process, if a response signal is received, the user is not asked to confirm. However, if the response signal contains model information and the user confirms it, safety can be ensured. Increase.

[0086] Also, for example, the response signal may contain device information instead of model information. In this case, the information processing terminal 1 determines whether the device information acquired from the response signal is valid, instead of the determination in B08. It is advisable to determine whether the device information 123 is stored. Both model information and device information may be included.

[0087] Also, for example, the information processing terminal 1 itself does not need to be set up. The user may be asked whether or not to set up the above.

[0088] Also, for example, in the embodiment, the session in which the electronic device 3 connects to the access point 4 Although the above is a case where the device has not yet completed setup, it may be a device where setup has already been completed. In this case, the electronic device 3 again performs the connection based on the connection information 222 received from the information processing terminal 1. For example, the electronic device 3 may have a different access point than the access point 4. After completing the setup to connect to an access point, connect to Access Point 4. If the electronic device 3 receives the connection information, the electronic device 3 sets up a connection to the access point 4. In this case, the electronic device 3 deletes the connection information of the other access points. Alternatively, only the connection information of the access point 4 may be stored.

[0089] In any of the flowcharts disclosed in the embodiments, any of the steps The order of execution of multiple processes in a group can be changed as desired as long as no contradictions occur in the process content. can be executed simultaneously or in parallel.

[0090] The processes disclosed in the embodiments may be implemented using a single CPU, multiple CPUs, ASICs, etc. The present invention may be implemented in any form of hardware, or a combination thereof.
