Description

  The present invention relates to a data communication method, a program, and an information processing apparatus, and more particularly, to a data communication method, a program, and an information processing apparatus by wireless communication.

  When various types of data communication 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 of various communication standards is performed according to communication settings between the MFP and the mobile terminal. In data communication, when performing large-capacity data data communication, Wi-Fi communication using Wi-Fi or the like is performed. On the other hand, when the devices are relatively close to each other and perform small-capacity data data communication, short-range wireless communication such as NFC (Near Field Communication) -based NFC communication is performed. In short-range wireless communication, wireless communication using Bluetooth has become widespread. In particular, BLE communication capable of executing power-saving data communication is widely used. When data communication is performed, an appropriate wireless communication according to the application is selected, and communication settings are switched in accordance with the selected wireless communication (for example, see Patent Document 1).

  For example, when a print job for executing a print process is transmitted from the mobile terminal to the MFP, communication settings are switched using NFC communication. In the NFC communication, communication setting between the devices having the NFC function is easily performed only by bringing the devices having the NFC function close to each other. For example, when the mobile terminal is touched on the NFC module provided in the MFP, the Wi-Fi between the MFP and the mobile terminal is set. Communication settings such as communication are performed. Thus, the mobile terminal can transmit the print job to the MFP by performing Wi-Fi communication even if the print job is large-capacity data (for example, see Patent Document 2).

JP-A-2004-364145 JP 2014-050015 A

  However, in the technique of Patent Literature 2, communication setting between the MFP and the portable terminal may not be performed in some cases. For example, if one of the MFP and the mobile terminal does not have the 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 performed.

  An object of the present invention is to provide a data communication method, a program, and an information processing device that can easily perform communication settings.

  In order to achieve the above object, a data communication method according to the present invention provides a BLE communication method based on one of notifications for performing BLE communication transmitted from each of a plurality of data communication devices to an information processing device possessed by a user. A data communication method for performing communication and transmitting setting information for performing setting of data communication by the BLE communication, wherein a device name for specifying a data communication device that has transmitted the notification among the plurality of data communication devices is provided. Generating a list in which a list is recorded, a calculating step of calculating a distance between the data communication device corresponding to the device name recorded in the list and the information processing device, and generating the list based on the calculated distance. Determining a data communication device that performs the BLE communication among the data communication devices corresponding to the recorded device names; and Characterized in that the over data communication device and a transmission step of transmitting the setting information to the information processing apparatus.

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

  Next, a procedure of the BLE communication executed in the data communication system 100 will be described.

  FIG. 4 is a sequence diagram illustrating BLE communication executed in data communication system 100 in FIG.

  In FIG. 4, first, the mobile terminal 101 and the MFP 102 are in a standby state in which neither packet communication is performed. Thereafter, when the transmission of the advertising packet is instructed by the CPU 301, the MFP 102 transits to the advertising state, and transmits the advertising packet to an unspecified number of destinations simultaneously (hereinafter, referred to as “broadcast transmission”) (step). S401). The advertising packet includes a model name (device name) and address information for specifying the MFP 102, a Tx Power Level indicating a radio field intensity transmitted by the MFP 102, UUID information of the MFP 102, and the like. Next, the MFP 102 continuously broadcasts the advertising packet at regular intervals (step S402). In the present embodiment, ADV_IND for connecting to an unspecified device is used as the type of advertising packet transmitted by broadcast.

  On the other hand, when the CPU 201 instructs the scanning of the advertising packet by the CPU 201, the mobile terminal 101 transitions to the scanning state, and receives the advertising packet broadcast-transmitted. In the scanning state, there are two scan states, a passive scan and an active scan. When transitioning from the standby state to the scanning state, the scan state is a passive scan. When receiving the advertising packet broadcast-transmitted during the passive scan, the mobile terminal 101 analyzes the received advertising packet and specifies the transmission destination of the advertising packet. The mobile terminal 101 transmits a scan request (SCAN_REQ) for requesting transmission of the detailed information of the MFP 102 to the specified transmission destination, for example, the MFP 102 (step S403). At this time, the scan state of the mobile terminal 101 transitions 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 portable 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 the MFP 102 by the processing of FIG. 5 described later, and transitions to the starting state. Upon receiving the advertising packet transmitted from the MFP 102, the mobile terminal 101 that has transitioned to the initializing state transmits a connect request (CONNECT_REQ) for requesting a BLE communication connection to the MFP 102 (step S405). When the MFP 102 receives the connect request (CONNECT_REQ) transmitted from the mobile terminal 101, the MFP 102 performs BLE communication connection. As a result, the BLE communication between the mobile terminal 101 and the MFP 102 is established, the mobile terminal 101 and the MFP 102 transition to the connection state, and the processing ends.

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

  FIG. 5 is a flowchart illustrating a procedure of a job transmission process 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 a program stored in the ROM 203 and the storage device 204.

  In FIG. 5, first, the CPU 201 determines whether or not a job transmission application for setting a job to be transmitted is being activated (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. The top screen 601 displays a set button group 602 for setting various jobs transmitted by the job transmission application and a device selection button 603 for setting a destination of the job.

  As a result of the determination in step S501, when the job transmission application is being activated, the CPU 201 determines whether or not the Bluetooth function of the mobile terminal 101 is valid (step S502). In the present embodiment, the validity or invalidity of the Bluetooth function is set based on the BT setting information set by the operation of the UI unit 106 by the user.

  As a result of the determination in step S502, when the Bluetooth function is valid, the CPU 201 proceeds to the processing in step S506 without performing the processing in steps S503 and S504 described later.

  When the Bluetooth function is disabled as a result of the determination in step S502, the CPU 201 displays an operation screen 604 shown in FIG. 6B for notifying the user that the Bluetooth function is enabled (step S503). . Next, the CPU 201 determines whether or not the setting button 605 for enabling the Bluetooth function on the operation screen 604 is pressed (step S504).

  As a result of the determination in step S504, when not the setting button 605 but the cancel button 606 for not setting the setting of the Bluetooth function valid, the CPU 201 notifies the display unit 212 that the job transmission process cannot be executed. The operation screen 607 shown in FIG. Thereafter, the CPU 201 determines whether or not the OK button 608 on the operation screen 607 has been pressed (step S505).

  If the result of the determination in step S505 is that the OK button 608 on the operation screen 607 has been pressed, the CPU 201 proceeds to the process 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 processing in step S504.

  As a result of the determination in step S504, when the setting button 605 is pressed, the CPU 201 sets the Bluetooth function to valid, and determines whether or not an instruction to generate a job transmission candidate list has been issued (step S506). In the job transmission candidate list, a model name (device name) that specifies a device that can perform BLE communication among a plurality of devices (hereinafter, referred to as “application-compatible devices”) corresponding to a preset job transmission application is included in the job. (Hereinafter, referred to as “job transmission candidate device”). In the present embodiment, for example, when the device selection button 603 for setting the destination of the job is pressed on the top screen 601, or when notifying that the destination of the job is not set, FIG. When a device selection setting button 611 for setting a job transmission destination is pressed on the screen 610 of (d), 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 of FIG. 7 to generate a job transmission candidate list (step S507) (generation unit). Next, the CPU 201 performs the communication switching process in FIG. 8 to connect the device to which the job is determined based on the job transmission candidate list (hereinafter, referred to as “job transmission destination device”) with the BLE communication. Then, Wi-Fi communication setting with the job transmission destination device is performed based on the communication setting information for connecting the Wi-Fi communication acquired by the BLE communication (step S508). Next, when the user instructs to end the job transmission application, the CPU 201 ends the job transmission application (step S509). In the present embodiment, when the user instructs the end of the job transmission application, the display unit 212 displays an operation screen illustrated in FIG. 6E for setting the Bluetooth function when the job transmission application is ended. 612 is displayed. When the button 613 of the operation screen 612 is pressed, the CPU 201 ends the job transmission application while the Bluetooth function is set to be valid. When the button 614 of the operation screen 612 is pressed, the CPU 201 sets the Bluetooth function to invalid. To end the job transmission application. Thereafter, when the processing of step S509 is completed, the CPU 201 ends this processing.

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

  As a result of the determination in step S510, when 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 of step S506.

  If the result of the determination in step S501 is that the job transmission application is not running, the CPU 201 determines that job transmission processing using the job transmission application is not to be performed, and ends this processing.

  If the result of the determination in step S510 is that the cancel button 615 on the operation screen 610 has been pressed, the CPU 201 performs the processing in step S509, and ends this processing.

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

  7, first, the CPU 201 sets the operation 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 or not an advertising packet has been received via the Bluetooth communication unit 105 (step S702). Here, the advertising packet is broadcast-transmitted from a plurality of devices capable of BLE communication, for example. In the present embodiment, the processing of step S702 and steps S703 and S706 described below are performed on the advertising packet broadcast-transmitted from each of the plurality of devices.

  When the advertising packet is received as a result of the determination in step S702, the CPU 201 determines whether or not the transmission destination of the received advertising packet (hereinafter, referred to as “packet transmission destination”) is an application-compatible device. (Step S703). In step S703, the transmission destination of the received advertising packet is determined by the application based on the address information, UUID information, and data identifiable by the job transmission application included in the advertising packet, which specifies the transmission destination of the advertising packet. It is determined whether the device is a compatible device.

  As a result of the determination in step S703, when the packet transmission destination is an application-compatible device, the CPU 201 controls the Bluetooth controller 210 to request the packet transmission destination to transmit the detailed information of the packet transmission destination ( SCAN_REQ). After that, the CPU 201 acquires a scan response (SCAN_RESP) transmitted from the packet transmission destination via the Bluetooth controller 210 (step S706). The scan response (SCAN_RESP) includes a model name for specifying a packet transmission destination, information of various processes executable at the packet transmission destination, for example, information on a printable paper size and a paper type.

  Next, the CPU 201 generates a job transmission candidate list based on the acquired scan response (SCAN_RESP) (step S707). That is, in the present embodiment, only the model name corresponding to the packet transmission destination that has 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 from the packet transmission destination corresponding to the model name recorded in the job transmission candidate list via the Bluetooth controller 210 for a certain period, the model corresponding to the packet transmission destination The name is deleted from the job transmission candidate list. Next, the CPU 201 determines whether or not the user has instructed to update the job transmission candidate list (step S708).

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

  As a result of the determination in step S702, when the advertising packet is not received, or as a result of the determination in step S703, the destination of the received advertising packet is not an application-compatible device, the CPU 201 causes the user to terminate the job transmission application. It is determined whether or not an instruction has been given (step S704).

  As a result of the determination in step S704, the CPU 201 returns to the process of step S702 when the end of the job transmission application is not instructed, and ends the job transmission application when the end of the job transmission application is instructed (step S705). The process ends.

  FIG. 8 is a flowchart illustrating a procedure of a communication switching process performed by the mobile terminal 101 in FIG.

  In FIG. 8, first, when one of the setting buttons 602, for example, a setting button 616 for performing print processing setting is pressed by the user on the top screen 601 (YES in step S <b> 801), the CPU 201 The print setting information for executing the print processing based on the operation of the UI unit 106 is set (step S802). Next, the CPU 201 determines whether the setting of the print setting information has been completed (step S803).

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

  When the setting of the print setting information is not completed as a result of the determination in step S803, the CPU 201 determines whether or not the user has instructed the end of the job transmission application (step S809).

  As a result of the determination in step S809, when the user does not give an instruction to end the job transmission application, the CPU 201 returns to the processing 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 processing.

  9A and 9B are flowcharts illustrating a procedure of a communication setting process performed by the mobile terminal 101 in FIG.

  Here, since the setting print job is large-capacity data including various print setting information used for the printing process, short-range wireless communication such as NFC communication with a low communication speed is not suitable for transmitting the setting print job. Therefore, in order to transmit a setting print job from the portable terminal 101 to the MFP 102, it is necessary to perform wireless communication suitable for communication of large-capacity data, for example, communication settings for performing Wi-Fi communication. In order to easily perform communication setting of Wi-Fi communication, for example, communication setting information is transmitted from the MFP 102 to the portable terminal 101 by NFC communication, and communication setting of Wi-Fi communication is 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. Accordingly, for example, if one of the mobile terminal 101 and the MFP 102 does not have the NFC function, NFC communication cannot be performed between the mobile terminal 101 and the MFP 102, and as a result, the communication setting between the mobile terminal 101 and the MFP 102 can be easily performed. Can not be done.

  In response to this, in the present embodiment, the distance between the portable terminal 101 and the job transmission candidate device is calculated using the widely spread BLE communication, and any of the job transmission candidate devices is calculated based on the calculated distance. The one device is determined as the job transmission destination device, and the communication setting information of the Wi-Fi communication is transmitted from the determined job transmission destination device to the portable terminal 101.

  9A and 9B, first, the CPU 201 determines whether the “approaching connection mode” for determining a job transmission destination device based on the distance to the job transmission candidate device calculated using BLE communication is set. Is determined (step S901).

  As a result of the determination in step S901, when the “approaching connection mode” is not set, when the user sets the job transmission destination device by operating the UI unit 106 (YES in step S902), the CPU 201 proceeds to step S908. Proceed to processing. In the present embodiment, for example, when the device selection button 603 on the top screen 601 is pressed by the user, an operation screen 617 shown in FIG. 6F for setting a job transmission destination device is displayed on the display unit 212. You. 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, when the “approaching connection mode” is set, the CPU 201 sets a specified value for determining a job transmission destination device used in step S905 described later (step S903). The specified value is set based on a distance at which the user of the portable terminal 101 can operate the job destination device. In the present embodiment, the specified value is set to, for example, 30 cm to 1 m. In step S903, a specified value stored in the ROM 203 in advance is set, but the specified value may be set based on an operation of the UI unit 106 by the user. Next, the CPU 201 measures the radio field 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). . Next, the CPU 201 acquires the Tx Power Level included in the transmitted advertising packet, and calculates the distance between the mobile terminal 101 and each job transmission candidate device based on the measured radio wave intensity and the acquired Tx Power Level. (Step S905) (calculation means). In step S905, using the Tx Power Level included in the advertising packet transmitted from the MFP 102 as a threshold, the radio wave intensity measured in step S904 based on the Tx Power Level and the strength of the radio wave received by the mobile terminal 101 (hereinafter, referred to as And the distance between the portable terminal 101 and the job transmission candidate device is measured based on the comparison result. Next, the CPU 201 determines whether or not there is any device among the job transmission candidate devices whose distance to the mobile terminal 101 is shorter than the specified value set in step S903 (hereinafter, referred to as “specified value achievement device”). (Step S906).

  As a result of the determination in step S906, when there is a specified value achieving device, the CPU 201 determines the specified value achieving device as the job transmission destination device (step S907) (determination unit). Next, the CPU 201 transmits a connect request (CONNECT_REQ) for requesting connection of the BLE communication to the job transmission destination device (step S908). Next, the CPU 201 determines whether or not the connection of the job transmission destination device and the BLE communication has been completed (step S909).

  As a result of the determination in step S909, when the connection of the BLE communication with the job transmission destination device is completed, the CPU 201 transmits a notification requesting the communication setting information of the Wi-Fi communication to the job transmission destination device (step S910) (transmission control). means). Next, the CPU 201 determines whether communication setting information of Wi-Fi communication of the job transmission destination device has been acquired from the job transmission destination device (step S911).

  As a result of the determination in step S911, when the communication setting information of the Wi-Fi communication of the job transmission destination device is acquired from the job transmission destination device, the Wi-Fi communication with the job transmission destination device is performed based on the acquired communication setting information. The communication setting of the Fi communication is performed (step S912). Next, the CPU 201 determines whether or not the Wi-Fi communication connection with the job transmission destination device has been completed (step S913).

  As a result of the determination in step S913, when the Wi-Fi communication connection with the job transmission destination device is completed, the CPU 201 proceeds to the process in step S805 in FIG.

  As a result of the determination in step S906, when there is no specified value achieving device, the CPU 201 determines whether or not the user has instructed to end the job transmission application (step S914). The process returns to step S904.

  As a result of the determination in step S909, when the connection of the job transmission destination device and the BLE communication is not completed, the CPU 201 determines whether or not the user has instructed to end the job transmission application (step S915), and ends the job transmission application. Is not instructed, the process returns to step S908.

  As a result of the determination in step S911, when the CPU 201 has not acquired the communication setting information of the Wi-Fi communication of the job transmission destination device from the job transmission destination device, the CPU 201 determines whether the user has instructed the end of the job transmission application. It is determined (step S916), and when the end of the job transmission application is not instructed, the process returns to step S911.

  As a result of the determination in step S914, S915, or S916, when the end of the job transmission application is instructed, the CPU 201 ends this processing.

  According to the processing of FIGS. 9A and 9B described above, the distance between the portable terminal 101 and each job transmission candidate device is calculated using BLE communication, and any one of the job transmission candidate devices is calculated based on the calculated distance. One device is determined as the job destination device, and the communication setting information of the Wi-Fi communication is transmitted from the job destination device to the mobile terminal 101. As a result, even if neither the mobile terminal 101 nor the job transmission destination device has the NFC communication function, the user himself / herself does not perform the communication setting of the data communication and the Wi-Fi communication transmitted from the job transmission destination device is not performed. Since the communication setting of the Wi-Fi communication between the mobile terminal 101 and the job destination device is performed based on the communication setting information, the communication setting between the mobile terminal 101 and the job destination device can be easily performed.

  9A and 9B, a specified value indicating a distance at which the user can operate the job destination device is set in advance, and a specified value achieving device among the job transmission candidate devices, for example, the MFP 102 Is determined as the job transmission destination device. Here, since the MFP 102 is a device located at a position where the user of the portable terminal 101 can operate the MFP 102, if the MFP 102 is a device that achieves the specified value, there is nothing other than the case where the user operates the MFP 102. Accordingly, the BLE communication between the portable terminal 101 and the MFP 102 is connected only when the user operates the MFP 102, so that it is possible to prevent the data communication between the portable terminal 101 and the MFP 102 from being performed more than necessary.

  Further, according to the processing of FIGS. 9A and 9B described above, the device selected by the user among the job transmission candidate devices is determined as the job transmission destination device. Accordingly, the communication setting information of the Wi-Fi communication is transmitted from the job transmission destination device selected by the user to the mobile terminal 101 by the BLE communication, so that the intention of the user can be reflected, and the user's ease of use can be improved. The communication settings between the portable terminal 101 and the job destination device can be easily set without impairing the communication settings.
