Description

The present invention relates to a data communication method, and more particularly to a data communication method by wireless communication.

2. Description of the Related Art When various data communications are performed between a data communication device such as an MFP and a mobile terminal such as a smart phone or a tablet PC, wireless communication is performed according to various communication standards according to communication settings between the MFP and the mobile terminal. In data communication, Wi-Fi communication or the like using Wi-Fi is performed when performing data communication of a large amount of data. On the other hand, when devices are relatively close to each other and perform data communication of small amount of data, near field 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 capable of executing power-saving data communication is widely used. When data communication is performed, appropriate wireless communication is selected according to the application, and communication settings are switched according to the selected wireless communication (see, for example, Patent Document 1).

For example, when transmitting a print job for executing print processing from a mobile terminal to an MFP, switching of communication settings using NFC communication is performed. In NFC communication, communication settings between devices having NFC functions can be easily performed simply by bringing the devices close to each other. Communication settings such as communication are performed. As a result, even if the print job is a large amount of data, the portable terminal can perform Wi-Fi communication and transmit the print job to the MFP (see, for example, Japanese Unexamined Patent Application Publication No. 2002-200022).

JP 2004-364145 A JP 2014-050015 A

However, in the technique disclosed in Japanese Patent Application Laid-Open No. 2002-200020, there are cases where communication settings cannot be made between the MFP and the mobile terminal. For example, if one of the MFP and 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 performed.

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

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

In FIG. 4, first, both the mobile terminal 101 and the MFP 102 are in a standby state in which packet communication is not performed. Thereafter, when CPU 301 instructs MFP 102 to transmit an advertising packet, MFP 102 transitions 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 (device name) and address information identifying the MFP 102, Tx Power Level indicating the radio wave intensity transmitted by the MFP 102, 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, ADV_IND is used as the type of advertising packet to be broadcast-transmitted to establish a connection with an unspecified device.

On the other hand, when CPU 201 instructs mobile terminal 101 to scan for advertising packets, mobile terminal 101 transitions to the scanning state and receives advertising packets broadcasted. There are two scan states, passive scan and active scan, in the scanning state. When transitioning from the standby state to the scanning state, the scan state is passive scan. When mobile terminal 101 receives an advertising packet broadcast-transmitted during passive scanning, mobile terminal 101 analyzes the received advertising packet and identifies the destination of the advertising packet. The mobile terminal 101 transmits a scan request (SCAN_REQ) for requesting transmission of detailed information of the MFP 102 to the specified 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 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 by the processing of FIG. 5 described later, and transitions to the initiating state. Upon receiving the advertising packet transmitted from the MFP 102, the mobile terminal 101 that has transitioned to the initiating state transmits a connect request (CONNECT_REQ) for requesting connection of BLE communication to the MFP 102 (step S405). When the MFP 102 receives the connect request (CONNECT_REQ) transmitted from the mobile terminal 101, it connects for BLE communication. 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 process ends.

Next, job transmission processing for transmitting a job for executing various processing such as print processing from the portable terminal 101 will be described. In this embodiment, as an example, a case of using Wi-Fi communication as a data communication means for transmitting jobs will be described.

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

The processing in FIG. 5 is performed by CPU 201 of mobile terminal 101 executing a program stored in ROM 203 and 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 running (step S501). When the job transmission application is running, the top screen 601 shown in FIG. 6A is displayed on the display unit 212 of the mobile terminal 101 . A top screen 601 displays a setting button group 602 for setting various jobs to be sent by the job sending application and a device selection button 603 for setting a job sending destination.

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

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

As a result of the determination in step S502, when the Bluetooth function is disabled, the CPU 201 displays the 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 has been pressed (step S504).

As a result of the determination in step S504, when the cancel button 606 for not enabling the setting of the Bluetooth function is pressed instead of the setting button 605, the CPU 201 notifies the display unit 212 that job transmission processing cannot be executed. The operation screen 607 shown in FIG. 6C is displayed for the purpose. After that, the CPU 201 determines whether or not 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 has been pressed, the CPU 201 proceeds to processing in step S509.

As a result of the determination in step S505, when the return button 609 of the operation screen 607 has been pressed, the CPU 201 returns to the process of 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 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 identifies a device capable of BLE communication among a plurality of devices compatible with a preset job transmission application (hereinafter referred to as “app compatible device”) is (hereinafter referred to as “job transmission candidate device”). In this embodiment, for example, when the device selection button 603 for setting the job transmission destination is pressed on the top screen 601, or when the job transmission destination is not set, the When the device selection setting button 611 for setting the 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 has been issued, the CPU 201 performs the list generation process of FIG. 7 to generate a job transmission candidate list (step S507) (generating means). Next, the CPU 201 performs the communication switching process of FIG. 8 to connect the job transmission destination device (hereinafter referred to as “job transmission destination device”) determined based on the job transmission candidate list through BLE communication. , the 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 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 a button 613 on the operation screen 612 is pressed, the CPU 201 terminates the job transmission application while leaving the Bluetooth function enabled, and when a button 614 on the operation screen 612 is pressed, the CPU 201 disables the Bluetooth function. to exit the job transmission application. After that, the CPU 201 ends this process when the process of step S509 is completed.

As a result of the determination in step S506, when an instruction to generate a job transmission candidate list has not been issued, the CPU 201 displays the operation screen 610 on the display unit 212, and determines whether or not 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 process of step S506.

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

As a result of the determination in step S510, when the cancel button 615 on the operation screen 610 has been pressed, the CPU 201 performs the processing in step S509 and terminates this processing.

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

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, CPU 201 determines whether or not an advertising packet has been received via Bluetooth communication unit 105 (step S702). Here, the advertising packet is, for example, broadcasted from a plurality of devices capable of BLE communication. In this embodiment, the processing of step S702 and steps S703 and S706, which will be described later, are performed on advertising packets broadcast-transmitted 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 or not 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, UUID information, and data identifiable by the job transmission application that specify the destination of the advertising packet included in the advertising packet. It is determined whether or not the device is compatible.

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 issue a scan request ( 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 the model name specifying the packet transmission destination, information on various processes executable at the packet transmission destination, for example, information on printable paper size and paper type.

Next, the CPU 201 generates a job transmission candidate list based on the obtained scan response (SCAN_RESP) (step S707). That is, in the present embodiment, only the model name corresponding to the packet transmission destination to which the scan response (SCAN_RESP) has been transmitted is recorded in the job transmission candidate list among the plurality of application-compatible devices. 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 of time, the model corresponding to the packet transmission destination The name is removed from the job submission candidate list. Next, the CPU 201 determines whether or not the user has given an instruction to update the job transmission candidate list (step S708).

As a result of the determination in step S708, the CPU 201 returns to the process of step S702 when the update of the job transmission candidate list is instructed, and proceeds to the process of step S508 in FIG. 5 when the update of the job transmission candidate list is not instructed.

When the advertising packet is not received as a result of the determination in step S702, or when the transmission 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 that the job transmission application has been terminated by the user. 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 termination of the job transmission application is not instructed, and terminates the job transmission application when termination of the job transmission application is instructed (step S705). End the process.

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

In FIG. 8, first, when the user presses one of the setting buttons 602, for example, the setting button 616 for setting print processing on the top screen 601 (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 setting of the print setting information is completed (step S803).

As a result of the determination in step S803, if the setting of the print setting information has been completed, the CPU 201 performs the communication setting processing of FIGS. A print job (hereinafter referred to as a "set print job") generated based on the print setting information set in step S804. In step S804, communication settings for Wi-Fi communication are performed in order to transmit the set print job to the job transmission destination device determined using BLE communication. Next, the CPU 201 cancels the communication setting for BLE communication and stops 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, when the CPU 201 obtains 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). , the process proceeds to step S509 in FIG.

As a result of the determination in step S803, if the setting of the print setting information is not completed, the CPU 201 determines whether or not the user has instructed to terminate 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 process of 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 mobile terminal 101 in FIG.

Here, since the setting print job is a large amount of data including various print setting information used for print processing, short-range wireless communication such as NFC communication with low communication speed is not suitable for sending 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 communication settings for wireless communication suitable for large-capacity data communication, such as Wi-Fi communication. In order to easily perform 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 widespread and many devices do not have NFC communication capabilities. Accordingly, for example, if either one of the mobile terminal 101 and the MFP 102 does not have an NFC function, NFC communication cannot be performed between the mobile terminal 101 and the MFP 102. As a result, communication settings between the mobile terminal 101 and the MFP 102 can be easily performed. can't go to

In response to this, in the present 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, one of the job transmission candidate devices is selected. or one device is determined as the job transmission destination device, and communication setting information for Wi-Fi communication is transmitted from the determined job transmission destination device to the portable terminal 101 .

In FIGS. 9A and 9B , first, the CPU 201 determines whether or not the “close connection mode” for determining the 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 "approach connection mode" is not set, the CPU 201 sets the job transmission destination device by the user's operation of the UI unit 106 (YES in step S902). Proceed to processing. In this 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. be. 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 one of the 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 "approach connection mode" is set, the CPU 201 sets a default value for determining the job transmission destination device used in step S905 (described later) (step S903). The prescribed value is set based on the distance at which the user who owns the portable terminal 101 can operate the job transmission destination device, and is set to 30 cm to 1 m, for example, in the present embodiment. In step S<b>903 , a specified value stored in advance in the ROM 203 is set, but the specified value may 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 names 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, the Tx Power Level included in the advertising packet transmitted from the MFP 102 is used as a threshold, and the radio wave intensity measured in step S904 (hereinafter referred to as (referred to as "received radio wave intensity"), and the distance between the mobile 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 a job transmission candidate device whose distance from the portable terminal 101 is shorter than the specified value set in step S903 (hereinafter referred to as a "specified value achieved device"). (step S906).

As a result of the determination in step S906, if there is a device that has achieved the specified value, the CPU 201 determines the device that has achieved the specified value as the job transmission destination device (step S907) (determining means). Next, the CPU 201 transmits a connect request (CONNECT_REQ) for requesting BLE communication connection to the job transmission destination device (step S908).
