  The CPU 110 is a processor that performs various arithmetic processing and generally controls the overall operation of the electronic timepiece 100. The CPU 110 reads a control program from the ROM 102, loads the control program into the RAM 111, and performs various operation processing such as display of time and arithmetic control and display related to various functions. Further, the CPU 110 controls the communication unit 103 to establish a connection with the wireless communication apparatus 200, and executes a wireless communication process described later.

  The RAM 111 is a volatile memory such as a static random access memory (SRAM) or a dynamic random access memory (DRAM), provides a work memory space to the CPU 110, stores temporary data, and stores various setting data. Do.

  The oscillation circuit 112 oscillates the vibrator 109 to generate and output a predetermined frequency signal (clock signal). For example, a crystal oscillator is used as the oscillation circuit 112.

  The divider circuit 113 divides the frequency signal input from the oscillation circuit 112 into a signal of a frequency used by the timer circuit 114 and the CPU 110 and outputs the divided signal. The frequency of this output signal may be changed based on the setting by the CPU 110.

The communication unit 103 demodulates, decodes, etc. the radio signal received via the antenna 104 and sends it to the CPU 110. Further, the communication unit 103 encodes, modulates, and the like the signal sent from the CPU 110 and transmits the signal to the outside through the antenna 104.

  Also, the communication unit 103 wirelessly communicates with the wireless communication apparatus 200 according to a communication protocol stack composed of a plurality of layers. In the present embodiment, the communication unit 103 performs wireless communication in accordance with the BLE stack which is a communication protocol stack in BLE. The BLE stack includes, as a plurality of layers, a link layer, a logical link control and adaptation protocol (L2CAP) layer, a security management (SM) layer, an attribute protocol (ATT) layer, and the like. The link layer is a hierarchy of protocols used for discovery, connection, and communication of devices close to the own device. The L2CAP layer is a layer of protocol that performs communication multiplexing. The SM layer is a protocol layer that defines a method of pairing, encryption, and distribution of encryption keys. The ATT layer is a layer of protocol that defines services and characteristics of BLE.

  The power supply unit 105 includes a battery, and supplies the power related to the operation of the electronic timepiece 100 to each unit at the operation voltage. In the present embodiment, a secondary battery such as a lithium ion battery is used as the battery of the power supply unit 105.

  The wireless communication device 10 is configured by the microcomputer 101, the ROM 102, the communication unit 103, the antenna 104, the power supply unit 105, and the vibrator 109.

  The display unit 106 includes, for example, a display screen such as a liquid crystal display (LCD) or an organic electro luminescence (EL) display.

In this case, the touch sensor detects a touch position and a touch mode related to the touch operation of the user on the touch sensor, and outputs an operation signal according to the detected touch position and the touch mode to the CPU 110.

  Next, the functional configuration of the CPU 110 of the electronic timepiece 100 according to the embodiment will be described. As shown in FIG. 2, the CPU 110 functions as a normal processing unit 121, a response necessity determination unit 122, and a response unit 123. The functions of the normal processing unit 121, the response necessity determination unit 122, and the response unit 123 may be realized by a single CPU, or may be realized by separate CPUs. In addition, those functions may be realized by a processor other than the microcomputer 101, such as a CPU of the communication unit 103.

  The CPU 110 as the normal processing unit 121 controls the communication unit 103 to execute a plurality of processes including transmission and reception of data with the wireless communication apparatus 200 based on counters corresponding to the plurality of processes. The plurality of processes are processes executed in a predetermined order set in advance between the electronic timepiece 100 and the wireless communication device 200. In the present embodiment, as shown in FIG. 3, the electronic timepiece 100 performs wireless communication after establishing a connection with the wireless communication device 200 to thereby perform service discovery processing (Service Discovery), profile configuration processing (Profile Config), and connection. An example in which update processing (Connection Update), connection continuation processing (Connect Continue), and termination processing (Terminate) are executed in this order will be described. The service discovery process is a process performed by the electronic timepiece 100 for determining the service possessed by the wireless communication device 200. The profile configuration process is a process for performing data reading and writing, setting of the electronic timepiece 100, setting of an application, and the like. The connection update process is a process for changing a data transmission / reception interval in connection and updating parameters related to connection. The connection continuation process is a process for changing the state of the electronic timepiece 100 or receiving a notification from the wireless communication device 200 by the user operating the wireless communication device 200 while maintaining the connection. The termination process is a process for disconnecting the connection due to a timeout or an operation of the electronic timepiece 100 or the like. In order to execute these processes in the above order, in the present embodiment, values from 1 to 5 are assigned to each process, and a counter ct corresponding to each process is set in the RAM 111. For example, in the case where “1” is assigned for service discovery processing, “2” for profile configuration processing, “3” for connection update processing, “4” for connection continuation processing, “5” for termination processing, and counter ct = 1 , Service discovery processing is performed. The normal processing unit 121 updates the counter ct to the next value when executing any of the above five processes, and executes the next process. The counter ct also indicates the processing being executed during the execution of the processing.

  Further, the CPU 110 as the normal processing unit 121 transmits and receives data to and from the wireless communication device 200 while each process is being performed. Specifically, when the process being executed is a process that requires reception of data from the wireless communication apparatus 200, the CPU 110 controls the communication unit 103 to receive data from the wireless communication apparatus 200. Then, when the received data is an event expected in the process being executed, the CPU 110 updates the counter to the next value. In addition, when the processing being executed is processing that requires transmission of data to the wireless communication device 200, the CPU 110 controls the communication unit 103 to transmit data to the wireless communication device 200. Then, when the CPU 110 does not receive data from the wireless communication device 200, the CPU 110 updates the counter to the next value.

  The CPU 110 as the response necessity determination unit 122 determines the necessity of the response to the wireless communication apparatus 200 for each of the plurality of layers constituting the communication protocol stack. In the present embodiment, the CPU 110 determines whether or not a response to the wireless communication device 200 is necessary for each of the four layers of the link layer, the L2CAP layer, the SM layer, and the ATT layer. Specifically, while the CPU 110 is processing any of service discovery processing, profile configuration processing, connection update processing, connection continuation processing, and end processing, the received data is not an expected event in the processing being executed. In the case where data is received from the wireless communication apparatus 200 in the case where it is a process that requires transmission, it is determined that a process different from the normal process is occurring, and the four layers constituting the BLE stack are included. For each of them, data check processing is performed to determine whether a response to the wireless communication apparatus 200 is necessary. Specifically, when it is determined that the received event is a link layer event, the CPU 110 executes link layer data check processing. When the CPU 110 determines that the received event is an ATT layer event and an ATT layer response flag described later is ON, the CPU 110 executes ATT layer data check processing. When the CPU 110 determines that the received event is an SM layer event and an SM layer response flag described later is ON, it executes an SM layer data check process. When the CPU 110 determines that the received event is an L2CAP layer event and an L2CAP layer response flag described later is ON, the CPU 110 executes an L2CAP layer data check process.

  Also, in data check processing such as link layer data check processing, ATT layer data check processing, SM layer data check processing, L2CAP layer data check processing, the CPU 110 needs a response for each command that may be received by the corresponding layer. Decide no. Then, when it is determined that the response is necessary, the CPU 110 turns on the response flag of each layer set in the RAM 111. For example, in the ATT layer data check process, commands such as "Write Request", "Write Response", "Write Command", "Handle Value Indication", and "Handle Value Notification" may be received. If the CPU 110 determines that a command requiring a response to the wireless communication apparatus 200, for example, “Write Response” or “Handle Value Indication” is received among these commands, the ATT layer response flag set in the RAM 111 is Turn on and prepare the data to respond. Similarly, in the link layer data check process, the SM layer data check process, and the L2CAP layer data check process, the CPU 110 determines whether a response is necessary and determines that a response is necessary, the link layer set in the RAM 111 The response flag, the L2CAP layer response flag, and the SM layer response flag are turned ON.

  The CPU 110 as the response unit 123 transmits a response to the wireless communication device 200 when it is determined that a response to the wireless communication device 200 is necessary. In this embodiment, the CPU 110 refers to the link layer response flag, the L2CAP layer response flag, the SM layer response flag, and the ATT layer response flag set in the RAM 111, and wirelessly transmits data to be responded when the flag is ON. It transmits to the communication device 200.

  FIG. 4 is a flowchart showing an example of the operation of the wireless communication process executed by the CPU 110 of the electronic timepiece 100 in the present embodiment. For example, when the connection with the wireless communication device 200 is established, the CPU 110 of the electronic timepiece 100 starts the wireless communication process shown in FIG.

  First, the CPU 110 determines whether the link layer response flag set in the RAM 111 is ON (step S101). If it is determined that the link layer response flag is not ON (step S101; No), the CPU 110 determines whether the L2CAP layer response flag set in the RAM 111 is ON (step S102). When it is determined that the L2CAP layer response flag is not ON (step S102; No), the CPU 110 determines whether the SM layer response flag set in the RAM 111 is ON (step S103). If it is determined that the SM layer response flag is not ON (step S103; No), the CPU 110 determines whether the ATT layer response flag set in the RAM 111 is ON (step S104).

  If it is determined that the link layer response flag is ON (step S101; Yes), if it is determined that the L2CAP layer response flag is ON (step S102; Yes), if it is determined that the SM layer response flag is ON (Step S103; Yes) or when it is determined that the ATT layer response flag is ON (Step S104; Yes), the CPU 110 executes response processing described later (Step S105).

  When the CPU 110 determines that the ATT layer response flag set in the RAM 111 is not ON (step S104; No), the CPU 110 determines whether the counter ct set in the RAM 111 is "1" (step S106). If the counter ct is “1” (step S106; Yes), the CPU 110 executes service discovery processing (step S107), and returns to step S101.

If the counter ct is not "1" (step S106; No), the CPU 110 determines whether the counter ct is "2" (step S108). If the counter ct is "2" (step S108; Yes), the CPU 110 executes profile configuration processing (step S109), and returns to step S101.

If the counter ct is not "2" (step S108; No), the CPU 110 determines whether the counter ct is "3" (step S110). If the counter ct is "3" (step S110; Yes), the CPU 110 executes connection update processing (step S111), and returns to step S101.

If the counter ct is not "3" (step S110; No), the CPU 110 determines whether the counter ct is "4" (step S112). If the counter ct is "4" (step S112; Yes), the CPU 110 executes the connection continuation process (step S113), and returns to step S101.

If the counter ct is not "4" (step S112; No), the CPU 110 determines whether the counter ct is "5" (step S114). If the counter ct is "5" (step S114; Yes), the end process is executed (step S115), and the wireless communication process is ended. If the counter ct is not "5" (step S114; No), for example, the value of the counter ct is set to "1" and the process returns to step S101.

  FIG. 5 shows the service discovery process (step S107 in FIG. 4), the profile configuration process (step S109 in FIG. 4), the connection update process (step S111 in FIG. 4), and the connection continuation process (step S111 in FIG. 4). The flowchart which shows an example of operation | movement of the transmission / reception process (data transmission / reception process) of the data with the radio | wireless communication apparatus 200 performed commonly in step S113 of FIG. 4 and completion | finish process (step S115 of FIG. 4) is shown.

  First, the CPU 110 determines whether it is in a state of waiting for reception of data from the wireless communication device 200 in the process currently being executed (step S201). When it is determined that the reception of data from the wireless communication device 200 is awaited (step S201; Yes), the CPU 110 controls the communication unit 103 to receive data from the wireless communication device 200. Is executed (step S202).

  Then, the CPU 110 determines whether the data received in step S202 is an event expected to be received in the process being executed (step S203). When it is determined that the received data is an event expected to be received (step S203; Yes), the CPU 110 updates the counter ct by incrementing the current counter ct by 1 (step S204). When it is determined that the received data is not an event expected to be received (step S203; No), the CPU 110 executes a layer determination process (step S205).

  If the CPU 110 determines that it is not waiting to receive data from the wireless communication device 200 (step S201; No), that is, if it determines that data should be transmitted to the wireless communication device 200, Data to be transmitted is set to the wireless communication device 200 (step S206). Then, the CPU 110 controls the communication unit 103 to execute data transmission / reception processing with the wireless communication device 200 (step S207).

  Then, CPU 110 determines whether or not there is data received from wireless communication apparatus 200 in step S207 (step S208). If it is determined that there is no data received from the wireless communication device 200 (step S208; No), the CPU 110 updates the counter ct by incrementing the current counter ct by 1 (step S209). When it is determined that there is data received from the wireless communication device 200 (step S208; Yes), the CPU 110 executes a layer determination process (step S205).

  FIG. 6 is a flowchart illustrating an example of the layer determination process performed by the CPU 110 of the electronic timepiece 100 in the present embodiment. First, the CPU 110 determines whether the event received in step S202 or step S208 shown in FIG. 4 is a link layer event (step S301). If it is determined that the received event is a link layer event (step S301; Yes), the CPU 110 executes link layer data check processing (step S302), and if it is determined that a response is necessary, the link layer response The flag is set to ON and this processing ends.

  When the CPU 110 determines that the received event is not a link layer event (step S301; No), the CPU 110 determines whether the received event is an ATT layer event (step S303). If it is determined that the received event is an ATT layer event (step S303; Yes), the CPU 110 determines whether the ATT layer response flag set in the RAM 111 is ON (step S304). If the CPU 110 determines that the ATT layer response flag is not ON (step S304; No), the ATT layer data check process is executed (step S305), and if it is determined that a response is necessary, the ATT layer response flag Set this to ON to complete this process. If it is determined that the ATT layer response flag is ON (step S304; Yes), the CPU 110 ends the present process.

  When the CPU 110 determines that the received event is not an ATT layer event (step S303; No), the CPU 110 determines whether the received event is an SM layer event (step S306). If it is determined that the received event is an SM layer event (step S306; Yes), the CPU 110 determines whether the SM layer response flag set in the RAM 111 is ON (step S307). If the CPU 110 determines that the SM layer response flag is not ON (step S307; No), the SM layer data check process is executed (step S308), and if it is determined that a response is necessary, the SM layer response flag Set this to ON to complete this process. If it is determined that the SM layer response flag is ON (step S307; Yes), the CPU 110 ends the present process.

  When the CPU 110 determines that the received event is not the SM layer event (Step S306; No), the CPU 110 determines whether the received event is the L2CAP layer event (Step S309). If it is determined that the received event is an L2CAP layer event (step S309; Yes), the CPU 110 determines whether the L2CAP layer response flag set in the RAM 111 is ON (step S310). If the CPU 110 determines that the L2CAP layer response flag is not ON (step S310; No), the L2CAP layer data check process is executed (step S311), and if it is determined that a response is necessary, the L2CAP layer response flag is Set this to ON to complete this process. When it is determined that the L2CAP layer response flag is ON (step S310; Yes), the CPU 110 ends the present process.

  Then, when the CPU 110 determines that the received event is not the L2CAP layer event (step S309; No), an error is notified (step S312), and the process ends.

  FIG. 7 is a flowchart showing an example of the response processing operation executed by the CPU 110 of the electronic timepiece 100 in the present embodiment. First, the CPU 110 sets transmission data to be transmitted to the wireless communication apparatus 200 (step S401). Then, the CPU 110 controls the communication unit 103 to execute data transmission / reception processing with the wireless communication device 200 (step S402). Then, the CPU 110 clears the response flag that has triggered the main processing (step S403).

  Then, CPU 110 determines whether or not there is data received from wireless communication apparatus 200 in step S402 (step S404). If it is determined that there is no data received from the wireless communication device 200 (step S404; No), the CPU 110 updates the counter ct by incrementing the current counter ct by 1 (step S405). When it is determined that there is data received from the wireless communication device 200 (step S405; Yes), the CPU 110 executes the layer determination process shown in FIG. 6 (step S406). Then, the CPU 110 returns to step S101 of FIG.

  As described above, the CPU 110 of the electronic timepiece 100 according to the present embodiment executes the plurality of normal processes in a predetermined order based on the counter corresponding to each of the plurality of processes. Further, at that time, for each of the plurality of layers constituting the communication protocol stack, it is determined whether or not a response to the wireless communication apparatus 200 is necessary, and when it is determined that a response is required, the wireless communication unit is controlled to respond Send Further, when the CPU 110 ends the process currently being executed, the CPU 110 updates the counter so as to represent the process to be executed next. Therefore, even if a process different from the normal process requiring a response is requested, the CPU 110 can stably maintain communication because the normal process is performed based on the counter while transmitting the response. Note that the counter does not necessarily have to be incremented by one. For example, the counter may be changed to a specific numerical value during each process such as the service discovery process. Therefore, the order may be switched by executing a plurality of normal processes based on the counter so that the process following the service discovery process is the connection update process or the termination process. Thus, the control of the counter can be changed as appropriate.

  In addition, the CPU 110 of the electronic timepiece 100 according to the present embodiment determines, for each of a plurality of layers, whether or not a response is necessary for each command that may be received from the wireless communication device 200 in the layer. Therefore, when receiving a command requiring a response, the CPU 110 can transmit a response corresponding to the command to the wireless communication device 200.

  Further, the CPU 110 of the electronic timepiece 100 according to the present embodiment responds, for each command that may be received for each of a plurality of layers, when an event different from an expected event occurs for each of a plurality of processes. Determine the necessity of Therefore, when an event different from the event of the normal processing occurs, the CPU 110 can transmit a response corresponding to the event to the wireless communication apparatus 200.

  Further, in the above embodiment, an example in which the electronic timepiece 100 and the wireless communication device 200 communicate by Bluetooth (registered trademark) has been described. However, the electronic timepiece 100 and the wireless communication device 200 may communicate using another communication method, for example, a wireless local area network (LAN) or Wi-Fi (registered trademark).

  Further, in the above embodiment, the electronic timepiece 100 has been described as an example, but the present invention is not limited to this, and is applicable to electronic devices capable of wireless communication. The present invention is particularly suitable for portable electronic devices equipped with a battery having a relatively small capacity, such as the electronic timepiece 100.

  Further, in the above embodiment, the example in which the CPU 110 performs the control operation has been described. However, the control operation is not limited to software control by the CPU. Some or all of the control operations may be performed using a hardware configuration such as a dedicated logic circuit.

  In the above description, the ROM 102 including a non-volatile memory such as a flash memory has been described as an example of a computer-readable medium storing a program related to the data communication process of the present invention and a program related to the advertisement process.
