Next, the functional configuration of the CPU 110 of the electronic clock 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. Further, those functions may be realized by a processor other than the microcomputer 101, such as the 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 / reception of data with the wireless communication device 200 based on the counters corresponding to the plurality of processes. The plurality of processes are processes executed between the electronic clock 100 and the wireless communication device 200 in a predetermined order set in advance. In the present embodiment, as shown in FIG. 3, the electronic clock 100 performs a service discovery process (Service Discovery), a profile configuration process (Profile Config), and a connection by performing wireless communication after establishing a connection with the wireless communication device 200. 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 clock 100 for determining the service of the wireless communication device 200. The profile configuration process is a process for reading / writing data, setting the electronic clock 100, setting an application, and the like. The connection update process is a process for changing the data transmission / reception interval in the connection and updating the parameters related to the connection.

The termination process is a process for disconnecting the connection by a timeout or an operation of the electronic clock 100 or the like. In order to execute these processes in the above order, in the present embodiment, values 1 to 5 are assigned to each process, and a counter ct corresponding to each process is set in the RAM 111. For example, when "1" is assigned to the service discovery process, "2" is assigned to the profile configuration process, "3" is assigned to the connection update process, "4" is assigned to the connection continuation process, and "5" is assigned to the end process, and the counter ct = 1. , The service discovery process is executed. When any one of the above five processes is completed, the normal processing unit 121 updates the counter ct to the next value and executes the next process. The counter ct also indicates the process being executed during the execution of the process.

Further, the CPU 110 as the normal processing unit 121 transmits / receives data to / from the wireless communication device 200 during the execution of each process. Specifically, the CPU 110 controls the communication unit 103 to receive data from the wireless communication device 200 when the processing being executed is a process that requires reception of data from the wireless communication device 200. Then, when the received data is an event expected in the processing being executed, the CPU 110 updates the counter to the next value. Further, when the processing being executed is a process requiring transmission of data to the wireless communication device 200, the CPU 110 controls the communication unit 103 to transmit the data to the wireless communication device 200. Then, when the CPU 110 does not receive the 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 a response to the wireless communication device 200 for each of the plurality of layers constituting the communication protocol stack. In the present embodiment, the CPU 110 determines the necessity of responding to the wireless communication device 200 for each of the four layers of the link layer, the L2CAP layer, the SM layer, and the ATT layer. Specifically, the CPU 110 receives data during any of service discovery processing, profile configuration processing, connection update processing, connection continuation processing, and termination processing, and is not an event expected in the processing being executed. In some cases, or when data is received from the wireless communication device 200 even though it is a process that requires transmission, it is determined that a process different from the normal process is occurring, and the four layers that make up the BLE stack. For each, a data check process for determining the necessity of responding to the wireless communication device 200 is executed. Specifically, when the CPU 110 determines that the received event is a link layer event, the CPU 110 executes a link layer data check process. Further, when the received event is an ATT layer event and the CPU 110 determines that the ATT layer response flag described later is ON, the CPU 110 executes the ATT layer data check process. Further, when the received event is an SM layer event and the CPU 110 determines that the SM layer response flag described later is ON, the CPU 110 executes the SM layer data check process. Further, when the received event is an L2CAP layer event and the CPU 110 determines that the L2CAP layer response flag described later is ON, the CPU 110 executes the L2CAP layer data check process.

Further, in the data check processing such as the link layer data check processing, the ATT layer data check processing, the SM layer data check processing, and the L2CAP layer data check processing, the CPU 110 requires a response for each command that may be received by the corresponding layer. Judge whether or not. Then, when the CPU 110 determines that a response is required, 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, there is a possibility of receiving commands such as "Write Request", "Write Response", "Write Command", "Handle Value Indication", and "Handle Value Notification". When the CPU 110 determines that it has received a command that requires a response to the wireless communication device 200, for example, "Write Response" or "Handle Value Indication", it sets the ATT layer response flag set in the RAM 111. Turn it on and prepare the data to respond. The CPU 110 also determines the necessity of a response in the link layer data check process, the SM layer data check process, and the L2CAP layer data check process, and when it is determined that a response is required, the link layer set in the RAM 111 is set. Turn on the response flag, L2CAP layer response flag, and SM layer response flag.

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 the present 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 when the flags are ON, wirelessly transmits the data to be responded to. It is transmitted to the communication device 200.
