Description

The present invention relates to a program, a communication terminal, and a communication system.

When various data communications are performed between a data communication device such as an MFP and a mobile terminal such as a smartphone or a tablet PC, wireless communication is performed using various communication standards depending on communication settings between the MFP and the mobile terminal. In data communication, Wi-Fi communication using Wi-Fi or the like is performed when large-capacity data communication is performed. On the other hand, when devices are relatively close to each other and perform data communication of a small amount of data, short-range wireless communication such as NFC communication using NFC (Near Field Communication) is performed. In short-range wireless communication, wireless communication using Bluetooth is widely used, and in particular, BLE communication that can perform power-saving data communication is widely used. When data communication is performed, an appropriate wireless communication is selected according to the purpose, and communication settings are switched in accordance with the selected wireless communication (for example, see Patent Document 1).

For example, when transmitting a print job for executing print processing from a mobile terminal to an MFP, communication settings are switched using NFC communication. With NFC communication, communication settings between devices that have NFC functions can be easily configured by simply bringing the devices close together. For example, if you touch a mobile terminal to the NFC module installed in an MFP, the Wi-Fi connection between the MFP and the mobile terminal will be established. Communication settings such as communication are performed. As a result, even if the print job is a large amount of data, the mobile terminal can perform Wi-Fi communication to transmit the print job to the MFP (for example, see Patent Document 2).

Japanese Patent Application Publication No. 2004-364145 Japanese Patent Application Publication No. 2014-050015

However, with the technique disclosed in Patent Document 2, there are cases where it is not possible to configure communication settings between the MFP and the mobile terminal. For example, if either the MFP or the mobile terminal does not have an NFC function, NFC communication cannot be performed between the MFP and the mobile terminal, and as a result, communication settings between the MFP and the mobile terminal cannot be easily configured.

An object of the present invention is to provide a program, a communication terminal, and a communication system that allow communication settings to be easily made.

In order to achieve the above object, the program of the present invention is a program that causes a communication terminal to execute each step, and includes multiple selections corresponding to multiple functions for communicating with an image processing device set as a communication destination. a step of displaying on a display section a first display in which a setting section for proceeding to the setting process of the object and the device used as the communication destination; and a message prompting the setting process to use the function and the setting process. displaying on the display section a second display in which a further setting section for proceeding to the next step is arranged, and the second display is displayed when the setting processing is performed after displaying the first display. The feature is that it is displayed when the

According to the present invention, communication settings can be easily performed.

Next, the procedure of BLE communication executed by the data communication system 100 will be explained.

FIG. 4 is a sequence diagram for explaining BLE communication performed in the data communication system 100 of FIG. 1.

In FIG. 4, first, both the mobile terminal 101 and the MFP 102 are in a standby state in which they do not perform packet communication. Thereafter, when the MFP 102 is instructed to transmit an advertising packet by the CPU 301, it transits to the advertising state and simultaneously transmits the advertising packet to an unspecified number of destinations (hereinafter referred to as "broadcast transmission") (step S401). The advertising packet includes the model name (equipment name) and address information that specify the MFP 102, the Tx Power Level that indicates the radio field strength transmitted by the MFP 102, the UUID information of the MFP 102, and the like. Next, the MFP 102 continuously broadcasts advertising packets at regular intervals (step S402). In this embodiment, the type of advertising packet to be broadcast is ADV_IND for connecting with unspecified equipment.

On the other hand, when the mobile terminal 101 is instructed to scan advertising packets by the CPU 201, it transitions to a scanning state and receives the broadcast advertising packets. There are two scanning states: passive scan and active scan. When transitioning from standby state to scanning state, the scan state is passive scan. When the mobile terminal 101 receives an advertising packet broadcast during passive scanning, it analyzes the received advertising packet and identifies the destination of the advertising packet. The mobile terminal 101 transmits a scan request (SCAN_REQ) to the specified destination, for example, the MFP 102, to request transmission of detailed information about the MFP 102 (step S403). At this time, the scan state of the mobile terminal 101 changes from passive scan to active scan.

Next, the MFP 102 transmits a scan response (SCAN_RESP) including detailed information of the MFP 102 to the mobile terminal 101 in response to the scan request (SCAN_REQ) transmitted from the mobile terminal 101 (step S404). The mobile terminal 101 stores the detailed information of the MFP 102 included in the received scan response in the ROM 203 or the like, determines the connection destination to be the MFP 102 through the process shown in FIG. 5, which will be described later, and transitions to an initiating state. When the mobile terminal 101 that has transitioned to the initiating state receives the advertising packet transmitted from the MFP 102, it transmits a connect request (CONNECT_REQ) for requesting connection of BLE communication to the MFP 102 (step S405). Upon receiving the connect request (CONNECT_REQ) transmitted from the mobile terminal 101, the MFP 102 establishes a BLE communication connection. As a result, BLE communication between the mobile terminal 101 and the MFP 102 is established, the mobile terminal 101 and the MFP 102 transition to a connected state, and this processing ends.

Next, job transmission processing for transmitting a job for executing various processes such as print processing from the mobile terminal 101 will be described. In this embodiment, as an example, a case will be described in which Wi-Fi communication is used as a data communication means for transmitting a job.

FIG. 5 is a flowchart showing the procedure of job transmission processing executed by the mobile terminal 101 in FIG.

The process in FIG. 5 is performed by the CPU 201 of the mobile terminal 101 executing programs stored in the ROM 203 and the storage device 204.

In FIG. 5, first, the CPU 201 determines whether a job transmission application for setting a job to be transmitted is running (step S501). When the job transmission application is running, a top screen 601 shown in FIG. 6A is displayed on the display unit 212 of the mobile terminal 101. On the top screen 601, a group of setting buttons 602 for setting various jobs to be transmitted using the job sending application and a device selection button 603 for setting the destination of the job are displayed.

As a result of the determination in step S501, if the job transmission application is being activated, the CPU 201 determines whether the Bluetooth function of the mobile terminal 101 is enabled (step S502). In this embodiment, the Bluetooth function is enabled or disabled based on BT setting information set by the user's operation of the UI unit 106.

As a result of the determination in step S502, if the Bluetooth function is valid, the CPU 201 proceeds to the process in step S506 without performing the processes in steps S503 and S504, which will be described later.

If the result of determination in step S502 is that the Bluetooth function is disabled, the CPU 201 displays an operation screen 604 shown in FIG. 6(b) to notify the user that the Bluetooth function is to be enabled (step S503). . Next, the CPU 201 determines whether the setting button 605 for enabling the Bluetooth function on the operation screen 604 has been pressed (step S504).

As a result of the determination in step S504, when the cancel button 606 for not enabling the Bluetooth function setting is pressed instead of the setting button 605, the CPU 201 notifies the display unit 212 that the job sending process cannot be executed. An operation screen 607 shown in FIG. 6(c) is displayed. After that, the CPU 201 determines whether the OK button 608 on the operation screen 607 has been pressed (step S505).

As a result of the determination in step S505, when the OK button 608 on the operation screen 607 is pressed, the CPU 201 proceeds to processing in step S509.

As a result of the determination in step S505, when the return button 609 on the operation screen 607 is pressed, the CPU 201 returns to the process in step S504.

As a result of the determination in step S504, when the setting button 605 is pressed, the CPU 201 enables the Bluetooth function and determines whether an instruction to generate a job transmission candidate list has been issued (step S506). In the job transmission candidate list, the model name (device name) that specifies a device that is capable of BLE communication among multiple devices that are compatible with a preset job transmission application (hereinafter referred to as "app compatible devices") is listed as a job. is recorded as a transmission candidate (hereinafter referred to as a "job transmission candidate device"). In this embodiment, for example, when the device selection button 603 for setting the job destination is pressed on the top screen 601, or when the device selection button 603 for notifying that the job destination is not set is pressed, the screen shown in FIG. When the device selection setting button 611 for setting a job transmission destination is pressed on the screen 610 in FIG. 6D, the CPU 201 determines that an instruction to generate a job transmission candidate list has been issued.

As a result of the determination in step S506, when an instruction to generate a job transmission candidate list is issued, the CPU 201 performs the list generation process shown in FIG. 7 to generate a job transmission candidate list (step S507) (generation means). Next, the CPU 201 performs the communication switching process shown in FIG. 8 to establish a BLE communication connection with the job transmission destination device (hereinafter referred to as "job transmission destination device") determined based on the job transmission candidate list. , performs Wi-Fi communication settings with the job destination device based on the communication setting information for establishing a Wi-Fi communication connection acquired through BLE communication (step S508). Next, when the user instructs the CPU 201 to terminate the job transmission application, the CPU 201 terminates the job transmission application (step S509). In this embodiment, when the user instructs to terminate the job transmission application, the display unit 212 displays an operation screen shown in FIG. 612 is displayed. When the button 613 on the operation screen 612 is pressed, the CPU 201 exits the job sending application with the Bluetooth function set to valid, and when the button 614 on the operation screen 612 is pressed, the CPU 201 disables the Bluetooth function. to exit the job submission application. Thereafter, when the process of step S509 is completed, the CPU 201 ends this process.

As a result of the determination in step S506, if the instruction to generate a job transmission candidate list is not given, the CPU 201 displays the operation screen 610 on the display unit 212, and determines whether the cancel button 615 on the operation screen 610 has been pressed. (Step S510).

As a result of the determination in step S510, if the device selection setting button 611 is pressed instead of the cancel button 615 on the operation screen 610, the CPU 201 returns to the processing in step S506.

As a result of the determination in step S501, if the job transmission application is not running, the CPU 201 determines not to perform job transmission processing using the job transmission application, and ends this processing.

As a result of the determination in step S510, when the cancel button 615 on the operation screen 610 is pressed, the CPU 201 performs the process in step S509 and ends this process.

FIG. 7 is a flowchart showing the procedure of list generation processing executed by the mobile terminal 101 in FIG.

In FIG. 7, first, the CPU 201 sets the operating state of the Bluetooth controller 210 from the standby state shown in FIG. 4 to the scanning state (step S701). Next, the CPU 201 determines whether an advertising packet has been received via the Bluetooth communication unit 105 (step S702). Here, the advertising packet is broadcast-transmitted from each of a plurality of devices capable of BLE communication, for example. In this embodiment, the processes of step S702 and steps S703 and S706, which will be described later, are performed on advertising packets broadcasted from each of a plurality of devices.

As a result of the determination in step S702, when an advertising packet is received, the CPU 201 determines whether the destination of the received advertising packet (hereinafter referred to as "packet destination") is an application-compatible device. (Step S703). In step S703, the destination of the received advertising packet is determined based on the address information that specifies the destination of the advertising packet included in the advertising packet, the UUID information, and the data that can be identified by the job sending application. It is determined whether the device is compatible.

As a result of the determination in step S703, if the packet destination is an application-compatible device, the CPU 201 controls the Bluetooth controller 210 to issue a scan request ( SCAN_REQ). After that, the CPU 201 acquires the scan response (SCAN_RESP) transmitted from the packet destination via the Bluetooth controller 210 (step S706). The scan response (SCAN_RESP) includes the model name that specifies the packet destination, information on various processes that can be executed at the packet destination, for example, information on printable paper sizes and paper types.

Next, the CPU 201 generates a job transmission candidate list based on the acquired scan response (SCAN_RESP) (step S707). That is, in this embodiment, only the model name corresponding to the packet transmission destination that transmitted the scan response (SCAN_RESP) among the plurality of application compatible devices is recorded in the job transmission candidate list. In step S707, for example, if the CPU 201 does not receive an advertising packet for a certain period of time from the packet transmission destination corresponding to the model name recorded in the job transmission candidate list via the Bluetooth controller 210, the The name will be removed from the job submission candidate list. Next, the CPU 201 determines whether the user has instructed to update the job transmission candidate list (step S708).

As a result of the determination in step S708, when the CPU 201 is instructed to update the job transmission candidate list, the process returns to step S702, and when the update of the job transmission candidate list is not instructed, the process proceeds to step S508 in FIG.

If the result of the determination in step S702 is that no advertising packet is received, or if the destination of the received advertising packet is not an application-compatible device as a result of the determination in step S703, the CPU 201 determines whether the job transmission application has been terminated by the user. It is determined whether an instruction has been given (step S704).

As a result of the determination in step S704, if the CPU 201 is not instructed to terminate the job transmission application, the process returns to step S702, and if the termination of the job transmission application is instructed, the CPU 201 terminates the job transmission application (step S705). Finish the process.

FIG. 8 is a flowchart showing the procedure of communication switching processing executed by the mobile terminal 101 in FIG.

In FIG. 8, first, when the user presses any one of the setting button group 602 on the top screen 601, for example, the setting button 616 for setting print processing (YES in step S801), the CPU 201 Print setting information for executing print processing is set based on the operation of the UI unit 106 (step S802). Next, the CPU 201 determines whether the setting of print setting information is completed (step S803).

As a result of the determination in step S803, if the setting of print setting information is completed, the CPU 201 performs the communication setting process of FIGS. 9A and 9B to send the job to the determined job destination device using BLE communication in step S802. The print job generated based on the print setting information set in (hereinafter referred to as "setting print job") is transmitted (step S804). In step S804, communication settings for Wi-Fi communication are performed in order to transmit the set print job to the determined job destination device using BLE communication. Next, the CPU 201 cancels the communication settings for the BLE communication and cancels the BLE communication (step S805). Next, the CPU 201 transmits the set print job to the MFP 102 by Wi-Fi communication via the wireless LAN communication unit 104 (step S806). Next, when the CPU 201 receives a notification indicating that the settings print job has been received from the MFP 102 (YES in step S807), the CPU 201 cancels the communication settings for Wi-Fi communication and cancels the Wi-Fi communication (step S808). , the process proceeds to step S509 in FIG.

As a result of the determination in step S803, if the setting of print setting information is not completed, the CPU 201 determines whether the user has instructed to terminate the job transmission application (step S809).

As a result of the determination in step S809, if the user does not instruct to terminate the job transmission application, the CPU 201 returns to the process in step S803.

As a result of the determination in step S809, when the user instructs to end the job transmission application, the CPU 201 ends this process.

9A and 9B are flowcharts showing the procedure of communication setting processing executed by the mobile terminal 101 in FIG. 1.

Here, since the settings print job is a large amount of data that includes various print setting information used in printing processing, short-range wireless communication such as NFC communication, which has a slow communication speed, is not suitable for sending the settings print job. Therefore, in order to send a settings print job from the mobile terminal 101 to the MFP 102, it is necessary to perform communication settings for wireless communication suitable for communication of large amounts of data, such as Wi-Fi communication. In order to easily configure communication settings for Wi-Fi communication, for example, communication setting information is transmitted from the MFP 102 to the mobile terminal 101 by NFC communication, and communication settings for Wi-Fi communication are performed based on the transmitted communication setting information. However, NFC communication is not widely used, and many devices do not have an NFC communication function. As a result, for example, if either the mobile terminal 101 or the MFP 102 does not have an NFC function, NFC communication cannot be performed between the mobile terminal 101 and the MFP 102, and as a result, communication settings between the mobile terminal 101 and the MFP 102 are facilitated. cannot be done.

Correspondingly, in this embodiment, the distance between mobile terminal 101 and job transmission candidate devices is calculated using widely spread BLE communication, and based on the calculated distance, which of the job transmission candidate devices is selected? One device is determined as the job destination device, and communication setting information for Wi-Fi communication is transmitted from the determined job destination device to the mobile terminal 101.

In FIGS. 9A and 9B, first, the CPU 201 determines whether the "approach connection mode" is set, which determines the job transmission destination device based on the distance to the job transmission candidate device calculated using BLE communication. (Step S901).

As a result of the determination in step S901, if the "approach connection mode" is not set, and the job transmission destination device is set by the user's operation on the UI unit 106 (YES in step S902), the CPU 201 performs the process in step S908. Proceed to processing. In this embodiment, for example, when the user presses the device selection button 603 on the top screen 601, an operation screen 617 shown in FIG. 6(f) for setting a job destination device is displayed on the display unit 212. Ru. The operation screen 617 displays the model name corresponding to the job transmission candidate list generated in step S707. In step S902, when the user selects any one of the plurality of model names displayed on the operation screen 617, the job transmission candidate device corresponding to the selected model name is determined as the job transmission destination device.

As a result of the determination in step S901, if the "approach connection mode" is set, the CPU 201 sets a specified value for determining the job destination device used in step S905, which will be described later (step S903). The specified value is set based on the distance at which the user who owns the mobile terminal 101 can operate the job destination device, and in this embodiment, is set to, for example, 30 cm to 1 m. In step S903, a predetermined value stored in the ROM 203 in advance is set, but the predetermined value may also be set based on the operation of the UI unit 106 by the user. Next, the CPU 201 measures the radio wave intensity of the advertising packet transmitted from each of the job transmission candidate devices corresponding to the model name recorded in the job transmission candidate list generated in step S707 of FIG. 7 (step S904). .

According to the process shown in FIGS. 9A and 9B described above, the distance between the mobile terminal 101 and each job transmission candidate device is calculated using BLE communication, and one of the job transmission candidate devices is selected based on the calculated distance. One device is determined as the job destination device, and communication setting information for Wi-Fi communication is transmitted from the job destination device to the mobile terminal 101. As a result, even if the mobile terminal 101 and the job destination device do not have an NFC communication function, data can be sent from the job destination device without the user having to configure communication settings for data communication. Communication settings for Wi-Fi communication between the mobile terminal 101 and the job destination device are performed based on the communication setting information for the Wi-Fi communication that has been set, so communication settings between the mobile terminal 101 and the job destination device can be easily configured. I can do it.

Further, according to the process of FIGS. 9A and 9B described above, a specified value indicating the distance at which the user can operate the job transmission destination device is set in advance, and a device that achieves the specified value among the job transmission candidate devices, for example, the MFP 102 is determined as the job destination device. Here, the MFP 102 is a device that exists in a position where it can be operated by the user who owns the mobile terminal 101, so when the MFP 102 is a device that achieves the specified value, it is only when the user operates the MFP 102. Thereby, the BLE communication between the mobile terminal 101 and the MFP 102 is connected only when the user operates the MFP 102, so it is possible to prevent data communication between the mobile terminal 101 and the MFP 102 from being performed more than necessary.

Furthermore, according to the process shown in FIGS. 9A and 9B described above, the device selected by the user from among the job transmission candidate devices is determined as the job transmission destination device. As a result, the communication setting information of Wi-Fi communication is transmitted from the job destination device selected by the user to the mobile terminal 101 via BLE communication, so the user's intention can be reflected, thereby improving the usability of the user. Communication settings between the mobile terminal 101 and the job destination device can be easily performed without compromising the quality of the job.
