Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to an information processing apparatus, a method of controlling the information processing apparatus, and a storage medium, and more particularly to an information processing apparatus that enables communication settings to be made with ease by wireless communication, a method of controlling the information processing apparatus, and a storage medium.

Description of the Related Art

When performing various data communication between a data communication apparatus, such as an MFP, and a mobile terminal, such as a smartphone or a tablet PC, wireless communication based on various communication standards is performed according to communication settings of the MFP and the mobile terminal. In data communication, in a case where communication of large-volume data is performed, communication, such as Wi-Fi communication using the standard of Wi-Fi, is performed. On the other hand, in a case where apparatuses are relatively close to each other, and communication of small-volume data is performed, short-distance wireless communication, such as NFC (Near Field Communication), is performed. As short-distance wireless communication, wireless communication using Bluetooth has come into widespread use, and more particularly, BLE (Bluetooth Low Energy) communication which makes it possible to perform power-saving data communication is widely used. Before data communication is performed, wireless communication suitable for its use is selected, and the communication settings are switched according to the selected wireless communication (see e.g. Japanese Patent Laid-Open Publication No. 2004-364145).
For example, before transmitting a print job for performing print processing from a mobile terminal to an MFP, communication settings are changed by using NFC. In NFC, only by moving the devices each having an NFC function closer to each other, it is possible to make communication settings for the devices with ease. For example, only by a user causing a mobile terminal to touch an NFC module provided in an MFP, settings of communication, such as Wi-Fi communication, between the MFP and the mobile terminal are made. This makes it possible, even in a case where the data of a print job is large-volume data, for the mobile terminal to transmit the print job to the MFP by performing Wi-Fi communication (see e.g. Japanese Patent Laid-Open Publication No. 2014-050015).
However, in the technique disclosed in Japanese Patent Laid-Open Publication No. 2014-050015, there is a case where the communication settings cannot be made for the MFP and the mobile terminal. For example, if one of the MFP and the mobile terminal is not equipped with the NFC function, NFC cannot be performed between the MFP and the mobile terminal, and as a result, it is impossible to make communication settings for the MFP and the mobile terminal with ease.

Next, BLE communication performed in the data communication system 100 will be described.
FIG. 4 is a sequence diagram useful in explaining BLE communication performed in the data communication system 100 shown in FIG. 1.
Referring to FIG. 4, first, the mobile terminal 101 and the MFP 102 are both in a standby state in which packet communication is not performed. Then, when transmission of an advertising packet is instructed by the CPU 301, the MFP 102 shifts to an advertising state, and transmits the advertising packet to an unspecified number of destinations (hereinafter referred to as the “broadcast transmission”) simultaneously (step S401). The advertising packet includes a model name (apparatus name) and address information that identifies the MFP 102, a Tx power level indicative of a radio field intensity of radio waves transmitted from the MFP 102, UUID (Universally Unique IDentifier) information of the MFP 102, and so forth. From then on, the MFP 102 continuously transmits an advertising packet by broadcast transmission at fixed intervals (step S402). In the present embodiment, as the type of the advertising packet transmitted by broadcast transmission, ADV_IND for connecting to an unspecified large number of apparatuses is used.
On the other hand, when the scan of the advertising packet is instructed by the CPU 201, the mobile terminal 101 shifts to a scanning state, and receives the advertising packet transmitted by broadcast transmission. The scanning state includes two scanning states: passive scan and active scan. When the mobile terminal 101 shifts from the standby state to the scanning state, the scanning state is passive scan. When the advertising packet transmitted by broadcast transmission is received during the passive scan, the mobile terminal 101 analyzes the received advertising packet, and identifies a transmission source of the advertising packet. The mobile terminal 101 transmits a scan request (SCAN_REQ) to the identified transmission source, i.e. the MFP 102, for requesting transmission of detailed information of the MFP 102 (step S403). At this time, the scan state of the mobile terminal 101 is shifted from passive scan to active scan.
Then, the MFP 102 transmits a scan response (SCAN_RESP) including the 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, e.g. in the RAM 202, determines the MFP 102 as a connection destination by performing a job transmission process described hereinafter with reference to FIG. 5, and shifts to an initiating state. Upon receipt of the advertising packet transmitted from the MFP 102, the mobile terminal 101 having shifted to the initiating state transmits to the MFP 102 a connection request (CONNET_REQ) for requesting BLE communication connection thereto (step S405). Upon receipt of the connection request (CONNET_REQ) transmitted from the mobile terminal 101, the MFP 102 performs BLE communication connection. By this connection, BLE communication between the mobile terminal 101 and the MFP 102 is established, and the mobile terminal 101 and the MFP 102 shift to a connected stat, followed by terminating the present process.
Next, the job transmission process for transmitting a job for executing various processing, such as print processing, from the mobile terminal 101 will be described. In the present embodiment, the description will be given, by way of example, of a case where Wi-Fi communication is used for data communication for transmitting a job.
FIG. 5 is a flowchart of the job transmission process performed by the mobile terminal 101.
The job transmission process in FIG. 5 is performed by the CPU 201 of the mobile terminal 101, which executes programs stored in the ROM 203 and the storage device 204.
Referring to FIG. 5, first, the CPU 201 determines whether or not the job transmission application for making settings of a job to be transmitted has been activated (step S501). If the job transmission application is activated, a top screen 601 shown in FIG. 6A is displayed on the display section 212 of the mobile terminal 101. The top screen 601 displays a setting button group 602 for setting various jobs to be transmitted by the job transmission application and a device selection button 603 for setting a job transmission destination.
If it is determined in the step S501 that the job transmission application has been activated, the CPU 201 determines whether or not the Bluetooth function of the mobile terminal 101 has been enabled (step S502). In the present embodiment, the enabling or disabling of the Bluetooth function is set based on the BT setting information set by user's operation of the UI section 106.
If it is determined in the step S502 that the Bluetooth function has been enabled, the CPU 201 proceeds to a step S506 without executing steps S503 and S504.
If it is determined in the step S502 that the Bluetooth function has been disabled, the CPU 201 displays an operation screen 604, shown in FIG. 6B, for prompting the user to make a setting for enabling the Bluetooth function (step S503). Then, the CPU 201 determines which of a setting button 605 for making a setting for enabling the Bluetooth function and a cancel button 606 for not making a setting for enabling the Bluetooth function has been pressed on the operation screen 604 (step S504).
If it is determined in the step S504 that the cancel button 606 has been pressed, the CPU 201 displays an operation screen 607 shown in FIG. 6C on the display section 212 so as to notify the user that the job transmission process cannot be performed. Then, the CPU 201 determines whether or not which of an OK button 608 and a return button 609 has been pressed on the operation screen 607 (step S505).
If it is determined in the step S505 that the OK button 608 has been pressed, the CPU 201 proceeds to a step S509.
If it is determined in the step S505 that the return button 609 has been pressed, the CPU 201 returns to the step S504.
If it is determined in the step S504 that the setting button 605 has been pressed, the CPU 201 makes a setting for enabling the Bluetooth function, and determines whether or not generation of a job transmission destination candidate list has been instructed (step S506). The job transmission destination candidate list records a model name (apparatus name) that identifies an apparatus capable of performing BLE communication as a candidate of a job transmission destination (hereinafter referred to as the “job transmission destination candidate apparatus”) out of a plurality of apparatuses compatible with the job transmission application (hereinafter referred to as the “application-compatible apparatus”), which are set in advance. In the present embodiment, for example, if the device selection button 603 for setting a job transmission destination is pressed on the top screen 601, or if a device selection setting button 611 for setting a job transmission destination is pressed on an operation screen 610, shown in FIG. 6D, which is displayed for notifying the user that the job transmission destination has not been set, the CPU 201 determines that generation of the job transmission destination candidate list has been instructed.
If it is determined in the step S506 that generation of the job transmission destination candidate list has been instructed, the CPU 201 performs a list generation process in FIG. 7, and thereby generates the job transmission destination candidate list (step S507). Then, by performing a communication switching process described hereinafter with reference to FIG. 8, the CPU 201 performs BLE communication connection to an apparatus which is determined, based on the job transmission destination candidate list, as a destination to which the job is to be transmitted (hereinafter referred to as the “job transmission destination apparatus”), and makes settings for Wi-Fi-communication with the job transmission destination apparatus based on the communication setting information for Wi-Fi communication connection, acquired by BLE communication (step S508). Then, when termination of the job transmission application is instructed by the user, the CPU 201 terminates the job transmission application (step S509). In the present embodiment, when termination of the job transmission application is instructed by the user, an operation screen 612, shown in FIG. 6E, for making a setting for the Bluetooth function before terminating the job transmission application is displayed on the display section 212. When a button 613 is pressed on the operation screen 612, the CPU 201 terminates the job transmission application in a state where the Bluetooth function is held enabled, whereas when a button 614 is pressed on the operation screen 612, the CPU 201 makes a setting for disabling the Bluetooth function and terminates the job transmission application, whereafter the present process is terminated. Note that in a case where the user instructs termination of the job transmission application either in the list generation process performed in the step S507, which is described in detail hereinafter with reference to FIG. 7, or in the communication switching process performed in the step S508, which is described in detail hereinafter with reference to FIG. 8, the present process is also terminated.
If it is determined in the step S506 that generation of the job transmission destination candidate list has not been instructed, the CPU 201 displays the operation screen 610 on the display section 212, and determines which of a cancel button 615 and the device selection setting button 611 has been pressed on the operation screen 610 (step S510).
If it is determined in the step S510 that the device selection setting button 611 has been pressed, the CPU 201 returns to the step S506.
If it is determined in the step S501 that the job transmission application has not been activated, the CPU 201 determines that the job transmission process using the job transmission application is not performed, and terminates the present process.
If it is determined in the step S510 that cancel button 615 has been pressed on the operation screen 610, the CPU 201 executes the step S509, and terminates the present process.
FIG. 7 is a flowchart of the list generation process performed by the mobile terminal 101 in the step S507 of the job transmission process in FIG. 5.
Referring to FIG. 7, first, the CPU 201 shifts the operation state of the Bluetooth controller 210 from the standby state to the scanning state, as described with reference FIG. 4 (step S701). Then, the CPU 201 determines whether or not an advertising packet has been received via the Bluetooth communication section 105 (step S702). Note that an advertising packet is transmitted e.g. from each of a plurality of apparatuses capable of performing BLE communication by broadcast transmission. In the present embodiment, the step S702 and steps S703 and S706, referred to hereinafter, are executed with respect to the advertising packet transmitted from each of the plurality of apparatuses by broadcast transmission.
If it is determined in the step S702 that an advertising packet has been received, the CPU 201 determines whether or not the transmission source of the received advertising packet (hereinafter referred to as the “packet transmission source”) is an application-compatible apparatus (step S703). In the step S703, the CPU 201 determines whether or not the transmission source of the received advertising packet is an application-compatible apparatus, based on the address information, UUID information, and data identifiable by the job transmission application, which are included in the advertising packet, for identification of the transmission source of the advertising packet.
If it is determined in the step S703 that the packet transmission source is an application-compatible apparatus, the CPU 201 causes the Bluetooth controller 210 to transmit a scan request (SCAN_REQ) to the packet transmission source, for requesting transmission of detailed information of the packet transmission source (step S706). Then, the CPU 201 acquires a scan response (SCAN_RESP) transmitted from the packet transmission source via the Bluetooth controller 210 (step S707). The scan response (SCAN_RESP) includes a model name that identifies the packet transmission source, and information on various processing operations which can be performed by the packet transmission source, such as information on printable sheet sizes and types.
Then, the CPU 201 generates the job transmission destination candidate list based on the acquired scan response (SCAN_RESP) (step S708). More specifically, in the present embodiment, out of the plurality of application-compatible apparatuses, only the model name corresponding to the packet transmission source which has transmitted the scan response (SCAN_RESP) is recorded in the job transmission destination candidate list. In the step S708, for example, if the CPU 201 does not receive an advertising packet from a packet transmission source corresponding to a model name recorded in the job transmission destination candidate list via the Bluetooth controller 210 for a specified time period, the model name corresponding to this packet transmission source is deleted from the job transmission destination candidate list. Then, the CPU 201 determines whether or not the update of the job transmission destination candidate list is instructed by the user (step S709).
If it is determined in the step S709 that the update of the job transmission destination candidate list is instructed, the CPU 201 returns to the step S702, whereas if the update of the job transmission destination candidate list is not instructed, the CPU 201 proceeds to the step S508 in FIG. 5.
If it is determined in the step S702 that an advertising packet has not been received, or if it is determined in the step S703 that the transmission source of the received advertising packet is not an application-compatible apparatus, the CPU 201 determines whether or not termination of the job transmission application is instructed by the user (step S704).
If it is determined in the step S704 that termination of the job transmission application is not instructed, the CPU 201 returns to the step S702, whereas if termination of the job transmission application is instructed, the CPU 201 terminates the job transmission application (step S705), followed by terminating the present process.
FIG. 8 is a flowchart of the communication switching process performed by the mobile terminal 101 in the step S508 of the job transmission process in FIG. 5.
Referring to FIG. 8, first, the CPU 201 determines whether or not a setting button 616 for performing the setting of print processing has been pressed by the user on the top screen 601 (step S801), and if the setting button 616 has been pressed (YES to the step S801), the CPU 201 sets print setting information for executing print processing based on user's operation of the UI section 106 (step S802). Then, the CPU 201 determines whether or not the setting of the print setting information is completed (step S803).
If it is determined in the step S803 that the setting of the print setting information is completed, the CPU 201 performs a communication setting process, described in detail hereinafter with reference to FIGS. 9A and 9B, to thereby make communication settings for transmitting a print job to the job transmission destination apparatus determined using BLE communication (step S804). More specifically, in the step S804, in order to transmit the print job, which has been generated based on the print setting information set in the step S802 (hereinafter referred to as the “set print job”), to the job transmission destination apparatus determined using BLE communication, communication settings for Wi-Fi communication are made. Then, the CPU 201 cancels the communication settings for BLE communication to stop BLE communication (step S805). Then, the CPU 201 transmits the set print job to the MFP 102 using Wi-Fi communication via the wireless LAN communication section 104 (step S806). Then, when a notification indicating receipt of the set print job is acquired from the MFP 102 (YES to a step S807), the CPU 201 cancels the communication settings for Wi-Fi communication, stops Wi-Fi communication (step S808), and proceeds to the step S509 in FIG. 5.
If it is determined in the step S803 that the setting of the print setting information is not completed, the CPU 201 determines whether or not termination of the job transmission application is instructed by the user (step S809).
If it is determined in the step S809 that termination of the job transmission application is not instructed by the user, the CPU 201 returns to the step S802.
If it is determined in the step S809 that termination of the job transmission application is instructed by the user, the CPU 201 terminates the present process.
FIGS. 9A and 9B are a flowchart of the communication setting process performed by the mobile terminal 101 in the step S804 of the communication switching process in FIG. 8.
In the present example, the data of the set print job is assumed to be large-volume data including various print setting information used for print processing, and hence short-distance wireless communication, such as NFC, which is low in communication speed, is not suitable for transmission of the set print job. For this reason, to transmit the set print job from the mobile terminal 101 to the MFP 102, it is necessary to make communication settings for performing wireless communication suitable for transmission of large-volume data, such as Wi-Fi communication. To facilitate making communication settings for Wi-Fi communication, it is envisaged, for example, that the communication setting information is transmitted from the MFP 102 to the mobile terminal 101 using NFC, and the communication settings for Wi-Fi communication are made based on the transmitted communication setting information. However, NFC is not in widespread use, and there are many devices which are not equipped with the NFC function. Therefore, for example, if one of the mobile terminal 101 and the MFP 102 is not equipped with the NFC function, NFC cannot be performed between the mobile terminal 101 and the MFP 102, and as a result, it is impossible to facilitate making communication settings for the mobile terminal 101 and the MFP 102.
To solve this problem, in the present embodiment, distances from the mobile terminal 101 to the job transmission destination candidate apparatuses are calculated using BLE communication in widespread use, and one of the job transmission destination candidate apparatuses is determined, based on the calculated distances, as the job transmission destination apparatus, whereby the communication setting information of Wi-Fi communication is transmitted from the determined job transmission destination apparatus to the mobile terminal 101.
Referring to FIGS. 9A and 9B, first, the CPU 201 determines whether or not an “approach-and-connect mode” is set for determining a job transmission destination apparatus based on distances to job transmission destination candidate apparatuses, which are calculated using BLE communication (step S901).
In a case where it is determined in the step S901 that the “approach-and-connect mode” is not set, when the job transmission destination apparatus is set by user's operation of the UI section 106 (YES to a step S902), the CPU 201 proceeds to a step S908. In the present embodiment, when the device selection button 603 on the top screen 601 is pressed by the user, for example, an operation screen 617 shown in FIG. 6F for setting the job transmission destination apparatus is displayed on the display section 212. The operation screen 617 displays the model names recorded in the job transmission destination candidate list generated in the step S707. In the step S902, when the user selects one of the plurality of model names displayed on the operation screen 617, a job transmission destination candidate apparatus corresponding to the selected model name is determined as the job transmission destination apparatus.
If it is determined in the step S901 that the “approach-and-connect mode” is set, the CPU 201 sets a specified value for determining a job transmission destination apparatus, which is used in a step S906, referred to hereinafter (step S903). The specified value is set to a distance to a job transmission destination apparatus within which the user having the mobile terminal 101 can operate the job transmission destination apparatus, and in the present embodiment, the specified value is set to a value e.g. within a range of 30 cm to 1 m. Although in the step S903, the specified value is stored in the ROM 203 in advance, the specified value may be set by user's operation of the UI section 106. Then, the CPU 201 measures a radio field intensity of an advertising packet transmitted from each of the job transmission destination candidate apparatuses corresponding to the model names recorded in the job transmission destination candidate list generated in the step S707 in FIG. 7 (step S904). Then, the CPU 201 acquires a Tx power level included in each transmitted advertising packet, and calculates a distance between the mobile terminal 101 and each job transmission destination candidate apparatus based on the measured radio field intensity and the acquired Tx power level (step S905). More specifically, in the step S905, the CPU 201 calculates, based the Tx power level included in the advertising packet transmitted from each job transmission destination candidate apparatus and the radio field intensity measured in the step S904 based on a intensity of electric wave transmitted from the job transmission destination candidate apparatus and received by the mobile terminal 101 (hereinafter referred to as the “received radio field intensity”), a distance between the mobile terminal 101 and the job transmission destination candidate apparatus. Then, the CPU 201 determines whether or not there is an apparatus which is shorter in distance from the mobile terminal 101 than the specified value set in the step S903 (hereinafter referred to as the “specified value-satisfying apparatus”) among the job transmission destination candidate apparatuses (step S906).
If it is determined in the step S906 that there is a specified value-satisfying apparatus, the CPU 201 determines the specified value-satisfying apparatus as the job transmission destination apparatus (step S907). Then, the CPU 201 transmits to the job transmission destination apparatus a connection request (CONNECT_REQ) for requesting BLE communication connection thereto (step S908). Then, the CPU 201 determines whether or not BLE communication connection to the job transmission destination apparatus has been established (step S909).
If it is determined in the step S909 BLE communication connection to the job transmission destination apparatus has been established, the process proceeds to a step S910 in FIG. 9B, wherein the CPU 201 transmits to the job transmission destination apparatus a notification for requesting the communication setting information of Wi-Fi communication. Then, the CPU 201 determines whether or not the communication setting information of Wi-Fi communication of the job transmission destination apparatus has been acquired therefrom (step S911).
If it is determined in the step S911 that the communication setting information of Wi-Fi communication of the job transmission destination apparatus has been acquired from the job transmission destination apparatus, the CPU 201 makes communication settings for Wi-Fi communication with the job transmission destination apparatus based on the acquired communication setting information (step S912). Then, the CPU 201 determines whether or not Wi-Fi communication connection to the job transmission destination apparatus has been established (step S913).
If it is determined in the step S913 that Wi-Fi communication connection to the job transmission destination apparatus has been established, the CPU 201 proceeds to the step S805 in FIG. 8.
If it is determined in the step S906 that there is no specified value-satisfying apparatus, the CPU 201 determines whether or not termination of the job transmission application is instructed by the user (step S914), and if termination of the job transmission application is not instructed, the CPU 201 returns to the step S904.
If it is determined in the step S909 that BLE communication connection to the job transmission destination apparatus has not been established, the CPU 201 determines whether or not termination of the job transmission application is instructed by the user (step S915), and if termination of the job transmission application is not instructed, the CPU 201 returns to the step S908.
If it is determined in the step S911 that the communication setting information of Wi-Fi communication of the job transmission destination apparatus has not been acquired from the job transmission destination apparatus, the CPU 201 determines whether or not termination of the job transmission application is instructed by the user (step S916), and if termination of the job transmission application is not instructed, the CPU 201 returns to the step S911.
If it is determined in the step S914, S915, or S916 that termination of the job transmission application is instructed by the user, the CPU 201 terminates the present process.
According to the above-described communication setting process in FIGS. 9A and 9B, the distances from the mobile terminal 101 to the job transmission destination candidate apparatuses are calculated, one of the job transmission destination candidate apparatuses is determined as the job transmission destination apparatus based on the calculated distances, whereafter the communication setting information of Wi-Fi communication is transmitted from the job transmission destination apparatus to the mobile terminal 101. As a consequence, even when neither the mobile terminal 101 nor the job transmission destination apparatus is equipped with the NFC function, communication settings for Wi-Fi communication between the mobile terminal 101 and the job transmission destination apparatus are made based on the communication setting information of Wi-Fi communication transmitted from the job transmission destination apparatus without a user himself/herself making communication settings for data communication, and hence it is possible to make communication settings for the mobile terminal 101 and the job transmission destination apparatus with ease.
Further, according to the above-described communication setting process in FIGS. 9A and 9B, a specified value indicative of a distance within which a user can operate the job transmission destination apparatus is set in advance, and out of the job transmission destination candidate apparatuses, a specified value-satisfying apparatus e.g. the MFP 102 is determined as the job transmission destination apparatus. Here, the MFP 102 is an apparatus which exists at a location from which the user having the mobile terminal 101 can operate the job transmission destination apparatus, and hence a case where the MFP 102 is a specified value-satisfying apparatus is nothing other than a case where the user is about to operate the MFP 102. Therefore, BLE communication connection is established between the mobile terminal 101 and the MFP 102 only when the user is about to operate the MFP 102, and hence it is possible to prevent data communication from being performed more than necessary between the mobile terminal 101 and the MFP 102.
Further, according to the above-described communication setting process in FIGS. 9A and 9B, in the case where the “approach-and-connect mode” is not set, out of the job transmission destination candidate apparatuses, an apparatus selected by a user is determined as the job transmission destination apparatus. This causes the communication setting information of Wi-Fi communication to be transmitted from the job transmission destination apparatus selected by the user to the mobile terminal 101 by BLE communication, and hence it is possible to cause the user's intension to be reflected. Therefore, it is possible to make communication settings for the mobile terminal 101 and the job transmission destination apparatus with ease without reducing user friendliness.
Although in the communication switching process in FIG. 8 and the communication setting process in FIGS. 9A and 9B, the description has been given of the case where the present invention is applied to execution of print processing, this is not limitative, but the present invention can be applied to processing executed based on a job transmitted from the mobile terminal 101, such as execution of scan processing. Also in a case where the present invention is applied to execution of scan processing, it is possible to obtain the same advantageous effects as provided by the above-described embodiment.
