However, in the wireless communication system of Patent Document 1, the first terminal is activated when the first terminal is powered on or when a button instructing to start pairing is operated on the first terminal, etc. Start sending advertisement packets at , and send advertisement packets periodically. Therefore, in the wireless communication system of Patent Document 1, there is a problem that the amount of communication increases and pairing cannot be performed efficiently.

Also, for example, in order to suppress the amount of communication, it is possible to send an advertisement packet only when pairing is started, but even in this case, the transmission timing of the advertisement packet (command (time from input to advertisement packet transmission) is different, and if there is a difference (for example, 5 seconds) from the user's desired transmission timing on a specific OS, the time it takes to complete pairing 1 will be longer, and multiple terminals may When pairing with , user convenience may be impaired.

Furthermore, when pairing with a plurality of terminals, the user must individually select from the plurality of terminals the terminal for which the pairing process is to be performed, resulting in a complicated task.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a communication device and the like that can perform pairing efficiently.

In order to solve the above problems, a communication device according to one aspect of the present invention includes a transmitter that transmits a first advertisement packet to each of one or more other communication devices, and a transmitter that transmits a first advertisement packet to each of one or more other communication devices. a receiving unit that receives a second advertising packet transmitted from each of the one or more other communication devices that received the first advertising packet transmitted by the receiving unit; a reception unit that receives an operation for determining a target communication device to be paired with the communication device among the one or more other communication devices that have transmitted the second advertisement packet; and the operation received by the reception unit. an execution unit that executes a pairing process for pairing the target communication device determined by the communication device with the communication device, and the transmission unit includes a A first advertisement packet is transmitted to each of the one or more other communication devices.

A target communication device to be paired with the communication device (meaning the own device) can be determined from among the one or more other communication devices that have received and transmitted the received one or more second advertisement packets. In this way, it is not necessary for each of the one or more other communication devices to transmit the second advertisement packet every time the pairing process is performed, and it is not necessary for each of the one or more other communication devices to transmit the second advertisement packet before performing the pairing process. Since the second advertisement packet can be transmitted from each of one or more other communication devices, an increase in communication amount can be suppressed and pairing can be performed efficiently.

Further, the transmitter may have a function of periodically transmitting the first advertisement packet, and may prohibit execution of the function when the execution unit executes the pairing process.

According to this, the second advertisement packet is sent only when the first advertisement packet is received, without having to continue sending the second advertisement packet periodically, so it is possible to suppress the increase in communication traffic and efficiently pair the packet. I can ring it. Further, if the communication device is installed at a high place and cannot be operated by a user by touching it directly, the transmission of the second advertisement packet can be started upon reception of the first advertisement packet.

According to this, the first advertisement packet is transmitted to each of the one or more second communication devices, and the second advertisement packet transmitted from each of the one or more second communication devices that received the first advertisement packet is transmitted to each of the one or more second communication devices. A target communication device to be paired with the first communication device can be determined from among the one or more second communication devices that are the senders of the second advertisement packet. As a result, it is not necessary to transmit the second advertisement packet from each of the one or more second communication devices every time the pairing process is performed.

FIG. 4 is a sequence diagram illustrating an example of the operation of the communication system 10 of FIG. 1. FIG. 5 is a sequence diagram showing an example of an operation that is a continuation of the example of the operation shown in FIG. 4. In addition, in FIG. 5, the first communication device 12 and the second communication device 14 will be explained as being on standby in a reception mode (described later) when the device is powered on.

As shown in FIG. 4, first, the user starts an application (step S1). The application is an application for pairing the first communication device 12 and the target communication device. For example, the app is installed on the first communication device 12, and the user operates the first communication device 12 to start the app. After the application is started, the ID of the first communication device 12 is set. Note that, for example, the user may set the ID of the first communication device 12 after the application is started.

When the application is started, the first communication device 12 switches from the reception mode to the transmission mode (step S2), and periodically transmits the first advertisement packet to each of the one or more second communication devices 14. (first transmission step) (step S3). For example, the transmission mode in the first communication device 12 is a mode in which the first communication device 12 transmits the first advertisement packet, and the reception mode in the first communication device 12 is a mode in which the first communication device 12 transmits the first advertisement packet. This is a non-transmission mode. Specifically, the first communication device 12 broadcasts the first advertisement packet to each of the one or more second communication devices 14. The first advertisement packet includes the ID of the first communication device 12 and the like. In the first transmission step, the first communication device 12 transmits the first advertisement packet to each of the one or more second communication devices 14 before performing the pairing process in the execution step.

When the first communication device 12 transmits the first advertisement packet to each of the one or more second communication devices 14, it switches from the transmission mode to the reception mode (step S4). Specifically, when the first communication device 12 broadcasts the first advertisement packet to each of the one or more second communication devices 14, the first communication device 12 switches from the transmission mode to the reception mode. These transmission mode and reception mode are repeatedly executed until the pairing process is started.

When the first advertisement packet is transmitted by the first communication device 12, each of the one or more second communication devices 14 receives the first advertisement packet (second reception step) (step S5), and determines the destination of the first advertisement packet. is confirmed (step S6). In this embodiment, the second receiving step is an example of a receiving step that receives the first advertisement packet transmitted by another communication device.

When each of the one or more second communication devices 14 receives the first advertisement packet in the second reception step, it switches from the reception mode to the transmission mode (step S7), and transmits the second advertisement packet for a predetermined period (step S7). (for example, 10 seconds) and then transmits it to the first communication device 12 (second transmission step) (step S8). For example, the transmission mode in the second communication device 14 is a mode in which the second communication device 14 transmits the second advertisement packet, and the reception mode in the second communication device 14 is a mode in which the second communication device 14 transmits the second advertisement packet. This is a non-transmission mode. Specifically, each of the one or more second communication devices 14 stores a value indicating the ID of the second communication device 14 that is its own device in the second communication device ID of the source in the second advertisement packet. , stores a value indicating the ID of the first communication device 12 that transmitted the first advertisement packet in the destination first communication device ID (see FIG. 3). In the present embodiment, the second transmitting step is an example of a transmitting step of transmitting the second advertising packet to another communication device only for a predetermined period when the first advertising packet is received in the receiving step.

In the present embodiment, the first receiving step is an example of a receiving step of receiving a second advertising packet transmitted from each of one or more other communication devices that received the first advertising packet transmitted in the transmitting step. It is.

When the first communication device 12 receives the second advertisement packet transmitted from each of the one or more second communication devices 14, it creates a list of the one or more second communication devices 14 (step S11).

Here, FIG. 6 is a schematic diagram showing a list of one or more second communication devices 14 created by the first communication device 12 of the communication system 10 of FIG. 1.

As shown in FIG. 6, for example, the first communication device 12 acquires at least the device name and BLE address of each second communication device 14 from one or more second advertisement packets, and A list of the second communication devices 14 is created using the device names and BLE addresses of the second communication devices 14.

Subsequently, in FIG. 5, after creating a list of one or more second communication devices 14, the first communication device 12 selects one or more second communication devices that are the source of the second advertising packet received in the first receiving step. An operation for determining a target communication device to be paired with the first communication device 12 from among the communication devices 14 is accepted (acceptance step) (step S12). As described above, for example, the operation includes an input operation in which the user inputs identification information for identifying the target communication device. For example, the identification information is the ID and device name of the target communication device, and the first communication device 12 selects the second communication device 14 having the input ID (device name) of the target communication device from the created list. It is searched and determined as the target communication device. That is, for example, the target communication device is determined simply by the user inputting the ID of the target communication device. Further, for example, the operation may be an operation of selecting and inputting a list of the one or more second communication devices 14 from the touch panel. In the present embodiment, the receiving step is for determining a target communication device to be paired with the communication device among the one or more other communication devices that have transmitted the one or more second advertisement packets received in the receiving step. This is an example of a reception step that accepts an operation.

The first communication device 12 executes a pairing process for pairing the first communication device 12 with the target communication device determined by the operation accepted in the reception step (first execution step), and executes a pairing process for pairing with the first communication device 12 in response to a pairing request from the first communication device 12 (second execution step) (step S13). Specifically, the first communication device 12 transmits a pairing request to the target communication device (step S14), the target communication device transmits a pairing response (step S15), and the first communication device 12 transmits a pairing response. receive. In this way, the target communication device and the first communication device 12 are paired. In the present embodiment, the first execution step is an example of an execution step that executes a pairing process for pairing the communication device with the target communication device determined by the operation accepted in the reception step, and the second execution step The step is an example of an execution step of executing a pairing process for pairing with another communication device in response to a pairing request from another communication device.

When the first communication device 12 and the target communication device are paired, the first communication device 12 transmits a connection request to the target communication device (step S16), and the target communication device transmits a connection response (step S17). , the first communication device 12 receives the connection response. In this way, a wireless connection between the target communication device and the first communication device 12 is established. The pairing performed here is performed using the list of one or more second communication devices 14 created in step S11 (based on the device name and BLE address of each of the devices), so the pairing process There is no need to send search packets (advertisement packets) to multiple target communication devices at the time of start. Specifically, the first communication device 12 does not need to periodically transmit the first advertisement packet to each of the one or more second communication devices 14, and when step S17 is executed, the first advertisement packet You may prohibit the function to periodically send .

When the wireless connection between the first communication device 12 and the target communication device is established, GATT communication becomes possible, the first communication device 12 transmits a command to the target communication device (step S18), and the target communication device sends a response. Transmit (step S19). In this way, after the wireless connection between the first communication device 12 and the target communication device is established, by transmitting a command from the first communication device 12 to the target communication device, the first communication device 12 is used to communicate with the target communication device. A communication device can be controlled.

As described above, in the communication system 10 according to the embodiment of the present invention, the first communication device 12 transmits the first advertisement packet, and the second communication device 14 transmits the first advertisement packet when receiving the first advertisement packet. 2. Send an advertisement packet. Therefore, the second communication device 14 does not need to continue transmitting the second advertisement packet, and only needs to transmit the second advertisement packet when receiving the first advertisement packet, thereby suppressing an increase in communication traffic. and pairing can be done efficiently.

Furthermore, in the communication system 10 according to the embodiment of the present invention, even if there are a large number of second communication devices 14, just by inputting identification information (for example, ID) for identifying the target communication device, It is also possible to pair the first communication device 12 and a target communication device. Therefore, in the pairing, the user can reliably specify the target communication device that he/she wants to specify, so that the pairing can be performed efficiently.

Furthermore, in the communication system 10 according to the embodiment of the present invention, the first communication device 12 transmits the first advertisement packet before accepting an operation for determining a target communication device. Therefore, it is not necessary to transmit the first advertisement packet for pairing after accepting the operation, and it takes time to pair the first communication device 12 and the target communication device after accepting the operation. can be suppressed, so pairing can be performed efficiently.

Further, in the communication system 10 according to the embodiment of the present invention, when a user operation for determining a target communication device is received, pairing of the first communication device 12 and the target communication device and the first communication device 12 are performed. Since the wireless connection between the target communication device and the target communication device can be automatically established, it is possible to reduce the amount of time and effort required by the user and enable efficient pairing.
