Embodiments of the present invention will be described in detail below with reference to the drawings. Note that the following embodiments do not limit the claimed invention, and not all combinations of features described in the embodiments are essential to the solution of the invention.

<First embodiment>
In this embodiment, a printer will be described as an example of a communication device to be connected, a smartphone will be an information processing device that performs wireless setting processing for the communication device, and a PC will be used as another information processing device. However, the present invention is not limited to this, and the information processing device may be a PC, the other information processing device may be a smartphone, or the information processing device and the other information processing device may be the same type of device. Furthermore, the processing of the communication device, information processing device, or other information processing device in this embodiment may be applied to various devices such as a digital camera.

In this embodiment, a PC (first device) connected to an access point (AP) wirelessly connects a smartphone (second device) and a printer to the AP, and uses wireless communication to communicate via the AP. Perform the setting process.

In the conventional approach, a user sends information about the AP to which the printer is to be connected from a first device connected to the AP to the printer, wirelessly connects the printer to the AP, and then connects the second device to the AP. Ta.

At this time, the first device or the second device establishes a P2P connection (direct wireless connection) with the printer in order to transmit information regarding the AP to the printer. In order to perform a P2P connection, the first device or the second device needs to identify the SSID of the printer to be connected. In order to identify the SSID of the printer, the first device or the second device performs processing to search for the SSIDs of surrounding APs (hereinafter referred to as AP search), and selects the SSID of the printer from the list of obtained SSIDs. , determining the connection destination. Next, the first device automatically identifies the AP to which the first device is connected among the APs to which the printer can be connected, and transmits information regarding that AP to the printer. The printer then uses that information to connect to that AP. Information regarding the AP includes an AP identifier (SSID, etc.) and authentication information (password, etc.) used in AP authentication processing.

In such a scenario, for example, an application performing connection processing for the first device may not be able to obtain the AP search result from the OS. In this case, since the PC cannot identify the SSID of the printer to be connected, the user must identify the SSID of the printer himself and establish a P2P connection between the first device and the printer by, for example, operating the OS GUI. It is necessary to perform an operation.

However, if the user is not accustomed to operating the first device, the user may not be able to call up the desired function. Furthermore, even if the desired function can be called, it may be difficult to specify the SSID of the desired printer, such as when there are many APs in the vicinity.

Therefore, in this embodiment, information about the printer to be connected and information about the AP to which the printer is connected are converted into a two-dimensional code such as a QR code (registered trademark) or a barcode, and displayed on the display section of the first device. do. Then, the two-dimensional code or barcode is photographed using an application that can obtain the AP search results from the OS running on another information processing device. The SSID of the printer is specified by an application on another information processing device that acquires information from the photographed two-dimensional code or barcode, and the other information processing device and printer establish a P2P connection. The other information processing device then transmits information regarding the AP acquired from the two-dimensional code or barcode to the printer, and the printer uses the acquired information to connect to the AP. This can reduce the effort required for the user to operate the GUI of the OS to select the SSID, and can also reduce the risk of connection failure due to the user's incorrect selection of the SSID.

In addition, in order to enable the use of the same printer from multiple information processing devices via a wireless network, all information processing devices must be connected to the wireless network in which the information processing device that configured the wireless settings for the printer is participating. Must be connected.

FIG. 1 is a diagram for explaining the system configuration in this embodiment. The system of this embodiment includes an information processing device such as a PC, a smartphone, a communication device such as a printer, and an AP.

In FIG. 1A, a PC 101 is connected to an access point (AP) 102 via a wireless LAN. Further, in FIG. 1C, a printer 103 and a smartphone 104 are also connected to the AP 102. That is, the PC 101 and the smartphone 104 are in a state where they can communicate with the printer 103 via the AP 102. This method of connecting via an AP is called infrastructure connection (hereinafter referred to as infrastructure connection). With infrastructure connection, it is possible to construct a network environment in which the PC 101 can communicate with two or more devices.

On the other hand, there is a connection method called P2P connection that allows communication only between two devices. As shown in FIG. 1(b), the smartphone 104 and printer 103 can also have a P2P connection through a wireless Ad-hoc connection. However, during the wireless Ad-hoc connection, both the smartphone 104 and the printer 103 use the wireless LAN interface for the wireless Ad-hoc connection, so they are unable to communicate with devices other than each other. For this reason, wireless Ad-hoc connections are often used as temporary connections.

The smartphone 104 performs processing to connect the printer 103 to the AP 102 via wireless LAN connection. To this end, the smartphone 104 transmits network setting information for connecting to the AP 102 to the printer 103 using a wireless Ad-hoc connection, and connects the printer 103 to the AP 102.

In this embodiment, the explanation will be given assuming that the PC 101 starts a connection process to connect the printer 103 to the access point 102, and the smartphone 104 acquires an image displayed on the PC 101 and instructs the printer 103 to connect to the AP 102. I do. However, the PC 101 and the smartphone 104 are examples of information processing devices, and one smartphone may start the connection process, and another smartphone may instruct the printer to connect to the AP.

FIG. 2 is a configuration diagram of a communication system including the PC 101, the smartphone 104, and the printer 103.

The PC 101 includes a CPU 201, a ROM 202, a RAM 205, a photographing device 207, a display device 208, an input interface (I/F) 209, and a wireless LAN I/F 206. Further, the PC 101 optionally includes a universal serial bus (USB) I/F 211 and a wired LAN I/F 210. Note that the PC 101 does not need to include the photographing device 207.

The CPU 201 reads the program 203 stored in the ROM 202 into the RAM 205 and executes it, thereby executing various processes for controlling the operation of the PC 101, including a wireless setting process for instructing the printer to set up a wireless network. I can do it. Details of the above wireless setting process will be described later.

The ROM 202 stores programs 203 corresponding to various processes including the program for the above wireless setting process, a wireless profile 204 to be described later, and the like. Furthermore, when a wireless setting processing program (such as an application) is installed on the PC 101, unique identification information is also stored in the ROM 202. This unique identification information is uniquely determined, for example, for a printer manufacturer or a printer model.

The wireless LAN I/F 206 is a communication unit including a wireless transmitting/receiving circuit, and can perform wireless communication in accordance with IEEE802.11, for example. The photographing device 207 is one or more image acquisition devices, such as a camera, arranged in the PC 101. The display device 208 is a device, such as a display or a projector, for notifying the user of information. The input I/F 209 is an input device such as a touch panel display, a keyboard, or a toggle switch. The wired LAN I/F 210 is a network interface that complies with, for example, the IEEE802.3 standard. The USB I/F 211 is an interface compliant with standards such as USB 1.0, USB 2.0, USB 3.0, and USB 3.1.

The PC 101 can be connected to the printer 103 in P2P via the USB cable 221 or via a wireless Ad-hoc connection. Further, the PC 101 can be connected to the LAN 224 via the Ethernet cable 223, and if the printer 103 can also be connected to the LAN 224, the PC 101 and the printer 103 can communicate with each other on the same LAN 224.

Further, the PC 101 is connected to the AP 102 via a wireless LAN (infrastructure connection), and the AP 102 is connected to the LAN 224 via the Ethernet cable 226, so that the PC 101 or the smartphone 104 can be connected to the LAN 224.

The PC 101 displays a two-dimensional code generated from information about the printer 103 and information about the wireless profile regarding the AP 102 on the display device 208. The smartphone 104 then photographs the displayed two-dimensional code with the photographing device 246, and acquires information from the acquired image of the two-dimensional code.

Here, the wireless profile 204 is information including specific information (SSID, etc.) of the AP 102 connected via the wireless LAN I/F 206, authentication information (password, etc.) used in authentication processing, and the like. The wireless profile 204 is stored and managed by the CPU 201 executing an OS (not shown) included in the ROM 202 .

The smartphone 104 includes a CPU 241, a ROM 242, a RAM 245, a wireless LAN I/F 246, a photographing device 247, a display device 248, and an input I/F 249. The components 241 to 249 of the smartphone 104 are the same as the components 201 to 209 of the PC 101, respectively, so a description thereof will be omitted.

Note that the smartphone 104 may optionally include at least one of a wired LAN I/F 210 and a USB I/F 211. In this case, the smartphone 104 may be connectable to the printer 103 via the USB cable 221 or the LAN 224.

The printer 103 includes a CPU 232, a ROM 233, a RAM 237, a display device 238, an input I/F 239, a printing unit 240, a USB I/F 231, and a wireless LAN I/F 236. The ROM 233 stores a program 234, a wireless profile 235, and the like. The CPU 232 executes various controls on the printer 103 by reading the program 234 from the ROM 233 into the RAM 237 and executing it. Note that the printer 103 does not need to have the USB I/F 231.

The printer 103 is capable of P2P communication with the PC 101 or the smartphone 104 via a USB cable 221 or a wireless Ad-hoc connection 222. Further, the printer 103 is connected to the AP 102 via a wireless LAN (infrastructure connection), and the AP 102 is connected to the LAN 224 via an Ethernet cable 226, so that the printer 103 can be connected to the LAN 224.

Here, the wireless profile 235 is information including settings such as the SSID and authentication information (password etc.) of the AP 102 connected via the wireless LAN I/F 236. The wireless profile 235 is stored and managed by the CPU 232 executing a program 234 included in the ROM 233.

Further, the ROM 233 also stores a unique SSID. This unique SSID is uniquely determined, for example, for a printer manufacturer or printer model. The wireless LAN I/F 236 of the printer 103 can operate as an AP corresponding to this unique SSID.

P2P communication using the wireless Ad-hoc connection 222 in this embodiment may be a communication method that does not use an AP, or may be a method in which the PC 101 or the printer 103 operates as an AP. For example, the wireless LAN I/F 236 operates as an AP corresponding to the above-mentioned unique SSID. In this case, the wireless LAN I/F 211 is connected to the wireless LAN I/F 236 as an AP corresponding to the unique SSID. According to this method, the PC 101 or the smartphone 104 can be directly connected to the printer 103 through the same connection process as the external AP 102. Therefore, even if the PC 101 or the smartphone 104 cannot execute processing for Ad-hoc connection not via an AP, P2P communication with the printer 103 is possible. That is, P2P communication between the smartphone 104 and the printer 103 may include a wireless Ad-hoc connection or an infrastructure mode connection.

Note that in the printer 103 of this embodiment, the user can perform an operation to connect the printer 103 to a desired AP according to the display on the display device 238. For example, the user can connect the printer 103 to the AP by inputting the SSID and password corresponding to the desired AP on the display device 238 of the printer 103.

However, the display device 238 of the printer 103 can take various forms depending on the type of printer 103, such as a small LCD display, a segment display liquid crystal display, or a flashing LED display. For example, if the display device 238 of the printer 103 is an LED that only flashes, it is not possible to notify the user of sufficient information compared to an LCD display that can display characters and images, and the printer 103 cannot be connected to a desired AP. It may be difficult for the user to connect to the

Therefore, in the conventional configuration, either the PC 101 or the smartphone 104 performs wireless setting processing on the printer 103 to connect the printer 103 to a predetermined AP. As a result, even a user who is not familiar with operating the printer 103 can easily connect the printer 103 to a desired AP. In particular, even if sufficient information cannot be displayed on the display device 238 and it is difficult to operate to connect the printer 103 to a desired AP, the user can easily operate according to the information displayed on the smartphone 104. It can be performed.

However, for example, a program that performs a connection process executed by the PC 101 may not be able to obtain the results of an AP search executed by the connected PC 101 from the OS. In this case, since the program that performs the connection processing cannot specify the SSID of the printer 103, the user identifies the SSID of the printer 103 himself, and performs a connection process to establish a P2P connection between the PC 101 and the printer 103, for example by operating the OS GUI. need to be done. If the user is not accustomed to operating the PC 101, the user may not be able to call up a desired function and may not be able to perform connection processing. Furthermore, even if the desired function can be called, it is difficult to identify the SSID of the printer 103 when there are many APs nearby, and it takes time to perform the connection process. In some cases.

Therefore, in this embodiment, the PC 101 converts information about the printer 103 and information about the AP 102 into a two-dimensional code, and displays the code on the display device 208. The smartphone 104 photographs the two-dimensional code displayed by the photographing device 207, and acquires information from the acquired image of the two-dimensional code. Then, the smartphone 104 performs an AP search, identifies the SSID of the printer 103 based on the result and information regarding the printer 103 obtained from the two-dimensional code, and establishes a P2P connection with the printer 103 instead of the PC 101. Thereafter, the smartphone 104 uses the information regarding the AP 102 acquired from the two-dimensional code to perform a wireless setting process to connect the printer 103 to the AP 102.

FIG. 3 is a flowchart illustrating an example of a series of processes performed by the PC 101 to communicate with the printer. Processing by the PC 101 is realized by the CPU 201 executing the program 203. Note that it is assumed here that the PC 101 is already connected to the external AP 102, and the SSID, password, and encryption method of the AP 102 are stored in the wireless profile 204. Further, it is assumed that the program 203 of the PC 101 for performing printer wireless setting processing can obtain the results of an AP search from the OS due to OS limitations and the like. Furthermore, the program 203 of the smartphone 104 is assumed to be able to obtain the results of an AP search from the OS due to OS limitations.

A predetermined screen is displayed on the display device 208 by a wireless setting processing program (such as an application) included in the program 203 in the PC 101 . When the user issues a predetermined instruction for the PC 101 to communicate with the printer 103 on the screen, the PC 101 starts processing for the wireless setting instruction. First, the PC 101 refers to the wireless profile 204 (S301) and acquires the wireless profile 204 including the SSID of the AP 102 connected at the start of the process shown in FIG.

The PC 101 generates a two-dimensional code including the SSID, password, and encryption method included in the wireless profile 204 acquired in S301 and unique identification information stored in the ROM 202 (S302), and displays the image on the display device 208 in FIG. A two-dimensional code display screen 400 as shown in (S303) is displayed. On the other hand, as will be described later, the two-dimensional code is photographed by the smartphone 104, and the smartphone 104 performs wireless setting processing on the printer 103 using information acquired from the two-dimensional code. The two-dimensional code display screen 400 shown in FIG. 4 has a two-dimensional code 401 and a "next" button 402. When the user presses the "Next" button 402 on the two-dimensional code display screen 400, the PC 101 searches for the printer 103 through the infrastructure connection via the AP 102 (S304), and determines whether the printer 103 has been detected (S305). Specifically, in S304, the PC 101 receives identification information (printer model name, serial number, etc.) from the device connected to the AP 102. Then, it is determined whether the received identification information includes identification information that matches the unique identification information stored in the ROM 202. If it is determined in S305 that the printer 103 has been detected, it is determined that communication with the printer 103 has been successful (S306), and the process ends. Note that the determination in S305 is continued until the printer 103 is detected.

Note that the two-dimensional code 401 may include a URL of a download page for a program (application, etc.) for wireless setting processing to be installed on the smartphone 104. Thereby, even if the application is not originally installed on the smartphone 104, the application can be easily installed by photographing the two-dimensional code. In this case, after installing and starting the application, the two-dimensional code photographed above needs to be photographed again.

FIG. 5A is a flowchart illustrating an example of a process of the smartphone 104 instructing execution of wireless setting process. The process shown in FIG. 5A is realized by the CPU 201 executing the program 203, and similarly, the process by the printer 103 is realized by the CPU 242 executing the program 244.

A predetermined screen is displayed on the display device 208 when the user instructs the smart phone 104 to execute a wireless setting processing program (such as an application) included in the program 203 . When the user performs a predetermined operation on the screen to connect the smartphone 104 to the printer 103, the smartphone 104 starts processing for instructing the printer 103 to execute wireless setting processing (S500). First, the smartphone 104 uses the photographing device 207 to photograph a two-dimensional code displayed on the display device 208 of the PC 101 (S501), and acquires information included in the photographed two-dimensional code (S502). Next, the smartphone 104 searches for a printer 103 that is in a wireless setting mode (described later) (S503), and determines from the detection result whether or not the SSID of the printer has been detected (S504). Specifically, an AP corresponding to the above unique SSID is searched, and it is determined whether the search is successful. The search process in S503 will be described later in the explanation of FIG.

If it is determined in S503 that a printer in wireless setting mode has been detected (an AP with a unique SSID has been detected) (Yes in S504), the smartphone 104 establishes a P2P connection with the printer 103 (S505). Specifically, the smartphone 104 connects the wireless LAN I/F 211 to an access point (printer 103) with a unique SSID.

On the other hand, if it is determined that the printer in the wireless setting mode has failed to be detected (the AP with the unique SSID was not detected) (No in S504), the smartphone 104 displays the screen shown in FIG. 8 on the display device 208. A detection failure screen 800 as shown in a) is displayed (S518). When the user presses the "end" button 802 on the detection failure screen 800 (No in S517), the smartphone 104 ends the wireless setting instruction process (S519). If the user presses the "retry" button 801 (Yes in S517), the smartphone 104 returns the process to searching for the printer 103 in the wireless setting mode again (S503).

Next, the smartphone 104 determines whether the information about the AP 102 acquired from the two-dimensional code is insufficient (S506). Specifically, in S506, the smartphone 104 determines whether the information acquired from the two-dimensional code includes the SSID, password, and encryption method of the AP 102. If the smartphone 104 determines that the information acquired from the two-dimensional code is insufficient (Yes in S506), the smartphone 104 refers to the wireless profile 204 (S507) and determines whether there is a wireless profile that includes the SSID of the AP 102 ( S508). If it is determined in S508 that there is no wireless profile, the smartphone 104 displays an AP information input screen 700 as shown in FIG. 7 on the display device 208 (S509).

The AP information input screen 700 shown in FIG. 7 includes an AP SSID 701, a password 702, an encryption method 703, a WEP key selection section 704, and a "next" button 705. The SSID of the AP 102 is displayed in the SSID 701. A password 702 is input by the user using a text box. As for the encryption method 703, an encryption method can be selected from a plurality of candidates using a list box. If the SSID 701 is encrypted using WEP, the smartphone 104 enables the WEP key selection section 704 and displays a message for the user to select a WEP key. When the "Next" button 705 on the AP information input screen 700 is pressed, the smartphone 104 stores the input information in the ROM 202 and closes the AP information input screen 700.

If the desired conditions are met in S506, the smartphone 104 transmits information used to establish a connection to the AP 102 to the printer 103 (S510). The desired condition is that the smartphone has determined that there is no shortage of information about the AP 102 acquired from the two-dimensional code, or has determined in S508 that there is a wireless profile that includes the SSID of the AP 102, or has determined that the information on the AP 102 has been determined in S509. This is the case when it is determined that . In S510, the smartphone 104 transmits information regarding the AP 102 (including the SSID, password, and encryption method) to the printer 103. Next, the smartphone 104 disconnects from the printer 103 (S511) and connects to the AP 102 (S512). In S512, the smartphone 104 performs connection processing with the AP 102 using the information about the AP 102 sent to the printer 103 in S510. Therefore, the smartphone 104 can be connected to the AP 102 without requiring the user to re-enter a password or the like.

Next, the smartphone 104 determines whether the connection with the AP 102 has been successfully established (S513). If it is determined that the smartphone 104 has successfully connected (S513: Yes), it searches for the printer 103 through the infrastructure connection via the AP 102 (S514), and determines whether the printer 103 has been detected (S515). Specifically, in S514, the smartphone 104 receives identification information (printer model name, serial number, etc.) from the device connected to the AP 102. Then, it is determined whether the received identification information includes identification information that matches the unique identification information stored in the ROM 202. If it is determined in S515 that the printer 103 has been detected (Yes in S515), the smartphone 104 displays a setting success screen 810 as shown in FIG. 8(b) on the display device 208 (S516). When the user presses the "OK" button 812 on the setup success screen 810, the smartphone 104 ends the wireless setup instruction process.

Note that the smartphone 104 may connect to the printer 103 at the timing when it is determined that the printer 103 has been detected in S515, or may connect to the printer 103 at the timing when the "OK" button 812 is pressed.

Note that the setting success screen 810 includes information on the AP 102 for configuring other information processing devices other than the PC 101 and the smartphone 104 so that they can communicate with the printer 103, and information on the IP address for identifying the printer 103 on the wireless network. A two-dimensional code 811 including information such as an address may be displayed. By photographing this two-dimensional code and acquiring this information, another information processing device connects to the AP 102, identifies the printer 103 on the wireless network, and performs communication without inputting information by the user. be able to.

On the other hand, if it is determined that the wireless setting in the printer 103 has failed through the processing in either S512 or S514, the smartphone 104 displays a setting failure screen as shown in FIG. 8C on the display device 208 as an error display. 820 is displayed (S517). When the user presses the "end" button 822 on the setting failure screen 820, the smartphone 104 determines not to retry the wireless setting instruction (No in S518), and the smartphone 104 ends the wireless setting instruction process. When the user presses the "Retry" button 821, the smartphone 104 determines to retry the connection setting process (Yes in S517), returns the process to S503, and searches for the printer 103 in wireless setting mode. do.

Next, the wireless setting process executed by the printer 103 will be described with reference to FIG. 5B. The process shown in FIG. 5B may be started on the condition that the user has given an instruction to shift to the wireless setting mode as the above-mentioned predetermined instruction, or may be started on other conditions. For example, even if the configuration is such that the printer 103 is temporarily switched to the wireless setting mode due to conditions such as when there is no wireless connection when the power is turned on, or when the power is turned on for the first time after purchase or after initialization. good.

First, when the wireless setting process is started, the printer 103 shifts to wireless setting mode, the printer 103 operates the wireless LAN I/F 236 as an AP with a unique SSID, and the printer 103 completes preparations for P2P connection ( S551). Specifically, the wireless LAN I/F 236 is operated as an AP for the above-mentioned unique SSID, and waits for a connection request in Ad-Hoc mode. When the smartphone 104 executes the processes of S503 to S505 in this state, the printer 103 starts P2P communication in response to a connection request from the smartphone 104.

Next, the printer 103 checks whether there is a wireless setting instruction from the smartphone 104 (S553), and if it is determined that there is no wireless setting instruction (No in S553), the process returns to S552. If the printer 103 determines that the wireless setting instruction has been received in S553 (Yes in S553), it attempts to establish a connection to the AP 102 specified by the smartphone 104 (S554). Specifically, in S554, the printer 103 attempts to establish a connection to the AP 102 using the SSID, password, and encryption method included in the wireless profile received from the smartphone 104. Then, the printer 103 determines whether the connection has been established successfully (S555), and if it is determined that the connection has failed, the printer 103 notifies the user via the display device 238 of the printer 103 that the wireless setting has failed ( S556). When the user performs an operation to cancel the setting error notified on the display device 238 of the printer 103, the printer 103 ends the wireless setting process. Even if it is determined in S555 that the connection process was successful, the printer 103 ends the wireless setting process.

The printer search process executed by the smartphone 104 in S503 will be described using FIG. 6. When the smartphone 104 starts the wireless setting mode printer search process, the smartphone 104 searches for surrounding SSIDs (S601). Specifically, the smartphone 104 instructs the OS to search for the SSID. Next, a list of SSIDs detected by the OS is acquired, and it is determined whether there is an SSID unique to the printer 103 in the list that includes the unique identification information of the printer 103 acquired in S502 (S602). If it is determined in S602 that the printer 103 has a unique SSID (Yes in S602), it is determined that the printer 103 in the wireless setting mode has been successfully detected (S603), and the wireless setting mode printer search process ends ( S605). On the other hand, if it is determined in S602 that the printer 103 does not have a unique SSID (No in S602), it is determined that the detection of the printer 103 in the wireless setting mode has failed (S604), and the search process for the printer in the wireless setting mode is performed. finish.

(Other examples)
Next, an example of processing of a setup program by the PC 101 for connecting the printer 103 to the wireless LAN will be described.

First, an example of a process for starting a wireless LAN setup process on the printer side will be described with reference to FIG. 17.

FIG. 17 is a flowchart illustrating an example of processing realized by the CPU 232 of the printer 103 executing the program 234 stored in the ROM 233. The process shown in FIG. 17 is executed by the printer 103 that has received an instruction from the user to shift to a wireless LAN setup mode using direct wireless connection. In one example, the printer 103 receives the instruction via the input I/F 239.

First, in step S1701, the printer 103 waits for a predetermined time until it receives wireless LAN setup information. Specifically, it waits until access information is received from the personal computer 101 or the smartphone 104. The access information includes, for example, the SSID of the access point 102 and the password used to connect with the access point 102. Next, the printer 103 advances the process to S1702 and determines whether wireless LAN setup information has been received. If reception of the wireless LAN setup information fails (No in S1702), the printer 103 advances the process to S1707, displays a reception failure message, and ends the process in FIG. If the wireless LAN setup information is received (Yes in S1702), the printer 103 advances the process to S1703. Next, in step S1703, the printer 103 attempts to connect to the access point 102 using the received access information. Next, in step S1704, the printer 103 determines whether the connection to the access point 102 is successful. If the connection from the printer 103 to the access point fails (No in S1704), the printer 103 advances the process to S1706, displays a message that the wireless LAN setup has failed on the display device 238, and ends the process. If the connection from the printer 103 to the access point is successful (Yes in S1704), the printer 103 advances the process to S1705, displays a message that the wireless LAN setup was successful on the display device 238, and ends the process in FIG. .

Next, with reference to FIG. 19, an example of processing of a setup program by the PC 101 for setting up the printer 103 on a wireless LAN will be described. The process flow of the PC 101 will be described below with reference to the flowchart in FIG. The process shown in FIG. 19 is realized by the CPU 201 of the PC 101 receiving an instruction to execute the setup process from the user and executing the setup program stored in the ROM 202. Further, it is assumed that the user executes the process of FIG. 17 for setting up the printer 103 by direct wireless connection to the wireless LAN in accordance with the flowchart shown in FIG.

The processes from S301 to S305 have been described with reference to FIG. 3, and will therefore be omitted. If no printer is detected in S305 (No in S305), the PC 101 advances the process to S1901 and executes another wireless LAN setup method. In this embodiment, "manual setting" and "setting with router buttons" can be selected. For example, when "manual setting" is selected, the user operates the input I/F 239 of the printer 103 and inputs the SSID and password of the access point 102 to connect to the access point 102. If "Set using router buttons" is selected, the user presses the input I/F of the printer 103 and the WPS button (not shown) of the access point 102, and connects the printer 103 and the access point 102 to WPS (Wi-Fi). (Protected Setup) process.

Next, the PC 101 advances the process to S1902 and searches for the printer 103 for which wireless LAN setup has been completed. The search is performed by transmitting and receiving specific commands between the PC 101 and the printer 103. Next, the PC 101 advances the process to S1903 and determines whether the printer 103 has been detected. For example, if it is determined in step S1902 that a specific command has been transmitted and received normally, the PC 101 determines that the printer 103 has been detected. If it is determined that the PC 101 has detected the printer 103 (Yes in S1903), the process in FIG. 19 ends. For example, if the PC 101 determines that the printer 103 could not be detected because a specific command was not sent or received normally (No in S1903), the PC 101 advances the process to S1904, notifies the user of the setup failure, and Finish the process.

<Second embodiment>
For example, an application that performs PC connection processing may not be able to obtain part of the information regarding the access point, such as the password for the access point, from the OS (Operating System). At this time, the printer may not be able to connect to the access point using only the access point information received from the PC. Therefore, in this case, it is necessary for the user to input access point information such as a password on the PC.

However, if the user makes a mistake when entering a password, the printer that receives the password will fail to connect to the access point, resulting in a connection error. Therefore, the user waits for the printer to experience a connection error before realizing that the password has been entered incorrectly. Furthermore, if a connection error occurs with the printer, the user must go to the printer and perform operations to clear the error or prepare the printer for reconnection. Passwords are often complex to ensure security, and as mentioned above, it is easy for users to enter them incorrectly.

Therefore, in the present embodiment, information about the destination printer including the SSID and part of information about the access point including the SSID are converted into one QR code and displayed on the display section of the PC. The QR code is then photographed using an application that runs on another information processing device and can obtain information about access points necessary for connection from the OS. The other information processing device and the printer establish a direct wireless connection using the printer's SSID obtained from the photographed QR code. The other information processing device then obtains information regarding the access point from the wireless profile stored on the other information processing device, which is linked to the SSID of the access point obtained from the QR code, and transmits it to the printer. The printer uses the acquired information to connect to the access point. Thereby, it is possible to reduce the effort of requiring the user to enter access point information such as a password, and it is also possible to reduce the risk that the connection will fail due to the user's input of the access point information incorrectly.

This embodiment will be described in detail below. Note that descriptions of configurations, processes, and functions similar to those of the first embodiment will be omitted.

FIG. 9 is a flowchart illustrating an example of a series of processes performed by the PC to communicate with the printer. The processing in FIG. 9 is realized by the CPU 201 executing the program 203 stored in the ROM 202. It is assumed here that the PC 101 has already been connected to the external access point 102, and the SSID, password, and encryption method of the access point 102 have been stored in the wireless profile 204. Further, it is assumed that the program 203 cannot obtain the password of the access point stored in the wireless profile 204 from the OS due to OS restrictions or the like.

A predetermined screen is displayed on the display device 208 by a wireless setting processing program (such as an application) included in the program 203 in the PC 101 . On that screen, when the PC 101 receives a predetermined instruction from the user for communicating with the printer 103, the PC 101 starts processing for the wireless setting instruction.

First, the PC 101 refers to the wireless profile 204 (S901) and acquires the wireless profile including the SSID of the access point 102 connected at the time of starting the process shown in FIG.

Next, the PC 101 advances the process to S902, executes an AP search, and obtains the AP search result from the OS. Subsequently, the PC 101 determines whether the SSID including unique identification information (hereinafter referred to as unique SSID) stored in the ROM 202 is included in the AP search result. If the unique SSID is included, the PC 101 generates a QR code including the SSID included in the wireless profile acquired in S901 and the unique SSID (S904), and displays the QR code as shown in FIG. 4 on the display device 208. Screen 400 is displayed (S905). If the unique SSID is not included, the QR code generated in S904 includes the aforementioned unique identification information instead of the unique SSID. The QR code display screen 400 has a QR code 401 and a "next" button 402. When the user presses the "Next" button 402 on the QR code display screen 400, the PC 101 searches for the printer 103 through the infrastructure connection via the access point 102 (S906), and determines whether the printer 103 has been detected (S906). S907). Specifically, in step S906, the PC 101 receives identification information (printer model name, etc.) from the device connected to the access point 102. Then, it is determined whether the received identification information includes identification information that matches the unique identification information stored in the ROM 202, and if so, it is determined that the printer 103 has been detected. On the other hand, as will be described later, the QR code is photographed by the smartphone 104, and the smartphone 104 performs wireless setting processing on the printer 103 using information acquired from the QR code. If it is determined in step S907 that the printer 103 has been detected, it is determined that communication with the printer 103 has been successful, and the process in FIG. 9 ends. Note that the determination in S907 is continued until the printer 103 is detected.

Note that the QR code 401 may include the URL of a download page for a wireless setting processing program (application, etc.) to be installed on the smartphone 104. Thereby, even if the application is not originally installed on the smartphone 104, the application can be easily installed by photographing the QR code. In this case, after installing and starting the wireless setting application, the QR code photographed above is photographed again.

FIG. 10 is a flowchart illustrating an example of a process in which the smartphone 104 transmits wireless settings to the printer 103 to instruct wireless connection. Processing by the smartphone 104 is realized by the CPU 241 executing a program 243 stored in the ROM 242, and similarly, processing by the printer 103 is realized by the CPU 232 executing a program 234 stored in the ROM 233.

A predetermined screen is displayed on the display device 208 by a wireless setting processing program (such as an application) included in the program 203 in the PC 101 . When the user issues a predetermined instruction to connect the PC 101 to the printer on the screen, the PC 101 starts processing for instructing wireless settings. Further, the smartphone 104 starts the process shown in FIG. 10 by activating an application for instructing the printer 103 to establish a wireless connection.

First, the smartphone 104 uses the photographing device 207 to photograph the QR code displayed on the PC 101 (S1001), and acquires information included in the photographed QR code (S1002). Next, the smartphone 104 searches for a printer 103 that is in a wireless setting mode (described later) (S1003), and determines whether the printer 103 is detected (S1004). Specifically, the smartphone 104 searches for the printer 103 corresponding to the above-mentioned unique SSID, and determines whether or not the printer 103 corresponding to the unique SSID is detected. Since the search process in S1003 has been described with reference to FIG. 6, the details will be omitted.

If it is determined in step S1003 that a printer in wireless setting mode has been detected (an access point with a unique SSID has been detected), the smartphone 104 establishes a direct wireless connection (wireless Ad-hoc connection) with the printer 103 ( S1005). Specifically, the smartphone 104 connects to an access point with a unique SSID via the wireless LAN I/F 211.

On the other hand, if it is determined that the detection of the printer in the wireless setting mode has failed, the smartphone 104 displays a detection failure screen 700 as shown in FIG. 8A on the display device 208 (S1015). When the user presses the "end" button 802 on the detection failure screen 800 (No in S1014), the smartphone 104 ends the wireless setting instruction process shown in FIG. 10. If the user presses the "retry" button 701 (Yes in S1014), the smartphone 104 returns the process to S1003 and searches for the printer 103 in the wireless setting mode again.

Next, the smartphone 104 refers to the wireless profile 204 (S1006) and acquires the wireless profile including the SSID of the access point 102. The smartphone 104 then transmits information instructing the printer 103 to perform wireless settings (S1007). Specifically, in S1007, the smartphone 104 transmits information about the access point 102 (including the SSID, password, and encryption method) to the printer 103. Next, the smartphone 104 disconnects the wireless Ad-hoc connection with the printer 103 and connects with the access point 102 (S1008). In step S508, the smartphone 104 performs connection processing with the access point 102 using the information about the access point 102 sent to the printer 103 in step S1007. Therefore, the smartphone 104 can reconnect to the access point 102 without requiring the user to re-enter a password or the like.

Next, the smartphone 104 determines whether the connection with the access point 102 was successful (S1009), and if it is determined that the connection was successful, the smartphone 104 searches for the printer 103 using the infrastructure connection via the access point 102 (S1010), and the printer 103 is connected to the access point 102. It is determined whether detection has been achieved (S1011). Specifically, in S1110, the smartphone 104 receives identification information (printer model name, etc.) from the device connected to the access point 102. Then, it is determined whether the received identification information includes identification information that matches the unique identification information stored in the ROM 202. If it is determined in S1111 that the printer 103 has been detected, the smartphone 104 displays a setting success screen 710 as shown in FIG. 8(b) on the display device 208 (S1012). When the user presses the "OK" button 712 on the setup success screen 710, the smartphone 104 ends the wireless setup instruction process. Note that the smartphone 104 may connect to the printer 103 at the timing when it is determined that the printer 103 has been detected in S1011, or may connect to the printer 103 at the timing when the "OK" button 712 is pressed. Note that the setting success screen 710 includes information about the access point 102 and wireless network information such as the IP address of the printer 103 in order to set up other information processing devices other than the PC 101 and the smartphone 104 so that they can communicate with the printer 103. A QR code 811 containing information for identifying the printer 103 may be displayed on the screen. By photographing this QR code and acquiring this information, the other information processing device mentioned above connects to the access point 102 without inputting information by the user, identifies the printer 103 on the wireless network, and communicates with the printer 103. It can be performed.

On the other hand, if it is determined that the wireless settings in the printer 103 have failed through the processing in either S1009 or S1011, the smartphone 104 displays a settings failure screen as shown in FIG. 8C on the display device 208 as an error display. 820 is displayed (S1013). When the user presses the "end" button 822 on the setting failure screen 820 (No in S1014), the smartphone 104 ends the wireless setting instruction process shown in FIG. 10. If the user presses the "retry" button 721 (Yes in S1014), the smartphone 104 returns to the process of searching for the printer 103 in the wireless setting mode again (S1003).

Subsequently, the wireless setting process for the printer 103 is the same as that in the first embodiment, so a description thereof will be omitted.

(Other examples)
Next, an example of processing of a setup program by the PC 101 for setting up the printer 103 via wireless LAN will be described.

First, an example of a process for starting a wireless LAN setup process on the printer side will be described with reference to FIG. 17.

FIG. 17 is a flowchart illustrating an example of processing realized by the CPU 232 of the printer 103 executing the program 234 stored in the ROM 233.

First, in step S1701, the printer 103 receives an instruction from the user to shift to a wireless LAN setup mode using direct wireless connection. In one example, the printer 103 receives the instruction via the input I/F 239. Next, the printer 103 advances the process to S1702 and waits for a predetermined time until receiving the wireless LAN setup information. Specifically, it waits until access information is received from the personal computer 101 or the smartphone 104. The access information includes, for example, the SSID of the access point 102 and the password used to connect with the access point 102. Next, the printer 103 advances the process to S1703 and determines whether wireless LAN setup information has been received. If reception of the wireless LAN setup information fails (No in S1703), the printer 103 advances the process to S1708, displays a reception failure message, and ends the process in FIG. 17. If the wireless LAN setup information is received (Yes in S1703), the printer 103 advances the process to S1704. Next, in step S1704, the printer 103 attempts to connect to the access point 102 using the received access information. Next, in S1705, the printer 103 determines whether the connection to the access point 102 is successful. If the connection from the printer 103 to the access point fails (No in S1705), the printer 103 displays a message that the wireless LAN setup has failed on the display device 238, and ends the process. If the connection from the printer 103 to the access point is successful (Yes in S1705), the printer 103 displays a message indicating that the wireless LAN setup was successful on the display device 238, and ends the process in FIG. 17.

Next, with reference to FIG. 11, an example of processing of a setup program by the PC 101 for setting up the printer 103 on a wireless LAN will be described. The flow of processing of the PC 101 will be described below with reference to the flowchart in FIG.

Note that the process shown in FIG. 11 is realized by the CPU 201 of the PC 101 receiving an instruction to execute the setup process from the user and executing the setup program stored in the ROM 202. Further, it is assumed that the user executes the process of FIG. 17 for setting up the printer 103 by direct wireless connection to the wireless LAN in accordance with the flowchart shown in FIG.

First, in S1101, the CPU 101 searches for a printer 103 that is waiting for wireless LAN setup via direct wireless connection. The search is performed by searching for an SSID that indicates that the device is waiting for wireless LAN setup via direct wireless connection. Note that in this embodiment, when the user instructs execution of the setup program, the PC 101 automatically searches for the printer 103 that is waiting for wireless LAN setup via direct wireless connection. The PC 101 that has executed the step may display a plurality of options for setting up the wireless LAN of the printer 103 and allow the user to make a selection. The process by which the PC 101 allows the user to select a wireless LAN setup method for the printer 103 will be described later with reference to FIG.

Next, in step S1102, the PC 101 determines whether the printer 103 waiting for wireless LAN setup via direct wireless connection has been detected. If it is determined that the PC 101 has detected the printer 103, the PC 101 advances the process to S1103 and executes wireless LAN setup by direct wireless connection from the PC 101. Next, the PC 101 advances the process to S1104 and searches for the printer 103 for which wireless LAN setup has been completed through infrastructure connection. The search is performed by transmitting and receiving specific commands between the PC 101 and the printer 103. Next, the PC 101 advances the process to S1106 and determines whether the printer 103 has been detected. If it is determined that the command has been transmitted and received normally, the PC 101 determines that the printer 103 has been correctly set up and ends the process in FIG. 11. If the command cannot be transmitted or received normally, the PC 101 determines that the wireless LAN setup via direct wireless connection has failed, and advances the process to S1107.

In S1107, the PC 101 executes processing to display a two-dimensional barcode on the screen. Here, details of S1107 executed by the PC 101 will be explained using the flowchart shown in FIG.

FIG. 12 is a flowchart showing a process flow in which the PC 101 that executes the setup program displays a two-dimensional barcode in order to set up the printer 103 via wireless LAN in another embodiment. First, in S1201, the PC 101 reads the wireless profile 204 stored in the ROM 202 of the PC 101. The contents of the wireless profile 204 are information used to connect the access point 225, and include, in one example, a Service Set Identifier (SSID) and a passphrase. Next, in S1202, the PC 101 provides URL information that allows the smartphone to load a program for making the printer 103 participate in the wireless LAN, SSID information necessary for directly connecting to the printer 103 wirelessly, and the printer 103. A character string is generated by combining the model name of the access point 225 with the SSID and passphrase of the access point 225, and is converted into a two-dimensional barcode. Although the explanation will be given assuming that the URL information is stored in advance in the program, in one example, the PC 101 obtains it from the printer 103 or an external terminal on the Internet via the wired LAN I/F 210 or wireless LAN I/F 206. You can. FIG. 13 shows a command necessary for the smartphone 104 to set up the printer 103 via wireless LAN, and is an example of a generated character string. Here, ssid1 is the SSID of the printer 103 necessary for direct wireless connection to the printer 103, and ssid2 is the SSID of the access point 225.

Next, the PC 101 displays the two-dimensional barcode generated in S1203 on the display device 208 of the PC 101. FIG. 14 shows a two-dimensional barcode screen 1400 displayed by the PC 101 executing the setup program. As will be described later with reference to S1108, the two-dimensional barcode 1401 included in the two-dimensional barcode screen 1400 is photographed with the photographing device 247 of the smartphone 104 as shown in FIG. 15, and the character string is read. The smartphone 102 can acquire the command shown in FIG. When the user instructs to end the display of the two-dimensional barcode, or when a predetermined period of time has elapsed, the PC 101 ends the process in FIG. 12 and proceeds to S1108 in FIG. 11.

Next, in S1108, the PC 101 executes wireless LAN setup through direct wireless connection using a two-dimensional barcode and a smartphone. The details of S1108 will be explained using the flowchart shown in FIG. 16.

FIG. 16 is a flowchart showing the flow of two-dimensional barcode reading processing executed by the smartphone 104 in one embodiment. The process in FIG. 16 is realized by the CPU 241 of the smartphone 104, which has been instructed by the user to execute the two-dimensional barcode reading application, executing the program 243 stored in the ROM 242. First, in S1601, the smartphone 104 reads a two-dimensional barcode displayed on the display screen 208 of the PC 101 using a two-dimensional barcode reading application. Next, the smartphone 104 advances the process to S1602, analyzes the read two-dimensional barcode, and loads the wireless LAN setup program according to the analyzed result. As a result of the analysis, the smartphone 104 acquires the command 1301 converted into a two-dimensional barcode in S1602. In this embodiment, the smartphone 104 acquires the information shown in FIG. 13. The first half of the command 1301 necessary to set up the wireless LAN in FIG. 13 is "https://cls. aaaaa/cls? "app/model" is an example of the information necessary to load the wireless LAN setup program. Next, in S1603, the smartphone 104 that executes the loaded wireless LAN setup program searches for a wireless setting mode printer 103 necessary for direct wireless connection to the printer 103. The search for the wireless setting mode printer 103 is performed by searching for "ssid1" in the second half of the command 1301 necessary for setting up the wireless LAN in FIG. The process of searching for the printer 103 in which the smartphone 104 is in the wireless setting mode has been described with reference to FIG. 6, so the description will be omitted. Next, the smartphone 104 advances the process to S1604 and determines whether the printer 103 in the wireless setting mode is detected. If the smartphone 104 detects the printer 103 in the wireless setting mode (Yes in S1604), the smartphone 104 advances the process to S1605. If the printer 103 in the wireless setting mode is not detected (No in S1604), the smartphone 104 advances the process to S1607, displays a failure screen, and ends the process in FIG. 16. In S1605, the smartphone 104 that executes the wireless LAN setup program establishes a wireless direct connection (P2P connection) with the printer 103, and the printer 103 is identified as an access point, which is extracted from the command 1301 used to set up the wireless LAN in FIG. 225 is sent to the printer 103. In one example, the smartphone 104 transmits the SSID (ssid2) and password (pass) of the access point 102 to the printer 103.

Next, the PC 101 advances the process to S1109 and searches for the printer 103 for which wireless LAN setup has been completed. The search is performed by transmitting and receiving a specific command between the PC 101 and the printer 103, as described in step S1105. Next, the PC 101 advances the process to S1110 and determines whether the printer 103 has been detected. If it is determined that the command has been transmitted and received normally, the PC 101 determines that the setup has been completed correctly and ends the process of FIG. 11. If communication is not possible, the PC 101 determines that the wireless LAN setup by direct wireless connection from the PC 101 has failed, and advances the process to S1111.

Next, the PC 101 executes another wireless LAN setup method in S1111. In this embodiment, "manual setting" and "setting with router buttons" can be selected. For example, when "manual setting" is selected, the user operates the input I/F 239 of the printer 103 and inputs the SSID and password of the access point 102 to connect to the access point 102. If "Set using router buttons" is selected, the user presses the input I/F of the printer 103 and the WPS button (not shown) of the access point 102, and connects the printer 103 and the access point 102 to WPS (Wi-Fi). (Protected Setup) process.

Next, the PC 101 advances the process to S1112 and searches for the printer 103 for which wireless LAN setup has been completed. Similar to S1105, the search is performed by transmitting and receiving a specific command between the PC 101 and the printer 103. Next, the PC 101 advances the process to S1113 and determines whether the printer 103 has been detected. For example, if it is determined in step S1112 that a specific command has been successfully transmitted and received, the PC 101 determines that the printer 103 has been detected. If it is determined that the PC 101 has detected the printer 103 (Yes in S1113), the process in FIG. 11 ends. For example, if the PC 101 determines that the printer 103 could not be detected because a specific command was not sent or received normally (No in S1113), the PC 101 advances the process to S1114, notifies the user of the setup failure, and Finish the process.
