In the sleep state, wireless communicator 20W is configured to stop transmitting a communication signal. Controller 20C is configured to set wireless communicator 20W to one of the awake state and the sleep state.

[0114] like Figures 6 to 8 As shown, wireless communicator 20W is configured to be in each of the first mode to the third mode in a state where wireless communicator 20W is in an awake state. Controller 20C is configured to store the current communication mode in memory 20M. Controller 20C is configured to set wireless communicator 20W to the current communication mode stored in memory 20M if controller 20C changes the state of wireless communicator 20W from the sleep state to the awake state.

[0116] like Fig. 9 As shown, if the wireless communication device 20 is turned on, the controller 20C sets the wireless communicator 20W to the first communication mode (step S1). The controller 20C determines whether the mode switch 20S receives the user input UW1 in the first communication mode (step S2). If the mode switch 20S receives the user input UW1 in the first communication mode, the controller 20C sets the wireless communicator 20W to the second communication mode (steps S2 and S3). The controller 20C determines whether the mode switch 20S receives the user input UW1 in the second communication mode (step S4). If the mode switch 20S receives the user input UW1 in the second communication mode, the controller 20C sets the wireless communicator 20W to the third communication mode (steps S4 and S5). The controller 20C determines whether the mode switch 20S receives the user input UW1 in the third communication mode (step S6). If the mode switch 20S receives the user input UW1 in the third communication mode, the program returns to step S1 (step S6). That is, if mode switcher 20S receives user input UW1 in the third communication mode, controller 20C sets wireless communicator 20W to the first communication mode (step S1 and step S6).

[0117] like Figures 10 to 12 As shown, controller 20C is configured to control wireless communicator 20W to perform notification based on the second communication protocol CP2. Fig.10 As shown, in the first communication mode, wireless communicator 20W has a first notification and a second notification different from the first notification. In the first notification and the second notification, wireless communicator 20W is configured to wirelessly transmit a connection request signal CS1 to establish a wireless connection between wireless communicator 20W and additional wireless communicator 24W.

[0118] Additional wireless communicator 24W is configured to wirelessly transmit connection signal CS2 using second communication protocol CP2 to establish a wireless connection between wireless communicator 20W and additional wireless communicator 24W. Controller 20C is configured to control wireless communicator 20W to establish a wireless connection between wireless communicator 20W and additional wireless communicator 24W using second communication protocol CP2 if controller 20C detects connection signal CS2.

[0119] In the case where the second communication protocol CP2 is Bluetooth or Bluetooth LE, for example, the connection request signal CS1 includes a notification packet having a format prescribed based on the second communication protocol CP2. The notification packet includes a universally unique identifier (UUID) indicating a service of the wireless communication device 20. That is, the wireless communication device 20 corresponds to the peripheral, and each of the additional electrical devices 24, 26, and 28 corresponds to the central.

[0120] like Fig.10 As shown, in the first notification, controller 20C is configured to control wireless communicator 20W to wirelessly transmit connection request signal CS1 at first frequency FQ1 in first time period PD1. Controller 20C is configured to control wireless communicator 20W to wirelessly transmit connection request signal CS1 at second frequency FQ2 different from first frequency FQ1 after first time period PD1. Controller 20C is configured to control wireless communicator 20W to wirelessly transmit connection request signal CS1 at second frequency FQ2 in second time period PD2 after first time period PD1.

[0121] In other words, controller 20C is configured to control wireless communicator 20W to wirelessly transmit connection request signal CS1 at a first interval V1 in a first period PD1. Controller 20C is configured to control wireless communicator 20W to wirelessly transmit connection request signal CS1 at a second interval V2 different from the first interval V1 after the first period PD1 has passed. Controller 20C is configured to control wireless communicator 20W to wirelessly transmit connection request signal CS1 at a second interval V2 in a second period PD2 after the first period PD1 has passed.

[0122] In this embodiment, the second frequency FQ2 is lower than the first frequency FQ1. The second interval is longer than the first interval. Examples of the first frequency FQ1 include 1 / 100 msec. -1 Examples of the second frequency FQ2 include 1 / 500 msec. -1 However, the first frequency FQ1 and the second frequency FQ2 are not limited to this embodiment. The second frequency FQ2 may be higher than the first frequency FQ1.

[0123] In this embodiment, the second period PD2 is different from the first period PD1. The second period PD2 is longer than the first period PD1. However, the second period PD2 may be equal to or shorter than the first period PD1.

[0124] like Fig.10 As shown, controller 20C is configured to control wireless communicator 20W to stop transmitting connection request signal CS1 after second period PD2. In this embodiment, if wireless communicator 20W does not detect connection signal CS2 in second period PD2, controller 20C controls wireless communicator 20W to stop transmitting connection request signal CS1 after second period PD2.

[0125] like Fig.11 As shown, if wireless communicator 20W detects connection signal CS2 before first period PD1 elapses, controller 20C controls wireless communicator 20W to stop transmitting connection request signal CS1 and establishes a wireless connection between wireless communicator 20W and additional wireless communicator 24W.

[0126] like Fig.12 As shown, if wireless communicator 20W detects connection signal CS2 before second period PD2 elapses, controller 20C controls wireless communicator 20W to stop transmitting connection request signal CS1 and establishes a wireless connection between wireless communicator 20W and additional wireless communicator 24W.

[0127] like Fig.13 As shown, in the second notification, controller 20C is configured to control wireless communicator 20W to wirelessly transmit connection request signal CS3 at third frequency FQ3 in third time period PD3. In the second notification, controller 20C is configured to control wireless communicator 20W to wirelessly transmit connection request signal CS3 at third interval V3 in third time period PD3.

[0128] In the case where the second communication protocol CP2 is Bluetooth or Bluetooth LE, for example, the connection request signal CS3 includes a notification data packet having a format specified based on the second communication protocol CP2. The notification data packet includes a universally unique identifier (UUID) indicating a service of the wireless communication device 20. The connection request signal CS3 is different from the connection request signal CS1. The UUID of the notification data packet of the connection request signal CS3 is different from the UUID of the notification data packet of the connection request signal CS1. For example, the UUID of the notification data packet of the connection request signal CS3 indicates a service for a bicycle meter and an application for a smartphone or tablet computer. The UUID of the notification data packet of the connection request signal CS1 indicates another service for a bicycle meter.

[0129] In this embodiment, the third frequency FQ3 is equal to the first frequency FQ1 and different from the second frequency FQ2. The third frequency FQ3 is higher than the first frequency FQ1. Examples of the third frequency FQ3 include 1 / 100 msec. -1 However, the third frequency FQ3 is not limited to this embodiment. The third frequency FQ3 may be different from the first frequency FQ1 and may be equal to or lower than the second frequency FQ2.

[0130] In this embodiment, the third period PD3 is equal to the first period PD1 and different from the second period PD2. The third period PD3 is shorter than the second period PD2. However, the third period PD3 may be equal to or longer than the second period PD2. The third period PD3 may be different from the first period PD1.

[0131] If wireless communicator 20W does not detect both connection signal CS2 and connection signal CS4 in third period PD3, controller 20C controls wireless communicator 20W to stop transmitting connection request signal CS3 after the third period PD3 has passed.

[0132] like Fig.14 and Fig.15 As shown, if wireless communicator 20W detects connection signal CS2 or CS4 before third period PD3 elapses, controller 20C controls wireless communicator 20W to stop transmitting connection request signal CS3 and establishes a wireless connection between wireless communicator 20W and additional wireless communicator 24W.

[0133] like Figure 6 As shown, after the first communication mode starts, controller 20C sets wireless communicator 20W to notification state ST11. In notification state ST11, controller 20C controls wireless communicator 20W to wirelessly transmit information using first communication protocol CP1, and controls wireless communicator 20W to perform second notification AD2 (using second communication protocol CP2) using second communication protocol CP2. Fig.13 ).

[0134] like Figure 5 As shown, in the case where the user uses the additional electric device 24, if the additional wireless communicator 24W is in a mode using the first communication protocol CP1, the controller 24C of the additional electric device 24 controls the display 24D to display the information wirelessly transmitted from the wireless communicator 20W using the first communication protocol CP1. In the case where the user uses the additional electric device 28, the controller 28C of the additional electric device 28 controls the display 28D to display the information wirelessly transmitted from the wireless communicator 20W using the first communication protocol CP1.

[0135] like Figure 6 As shown, in the second notification AD2, controller 20C controls wireless communicator 20W to Fig.13 ) uses the second communication protocol CP2 to wirelessly transmit a connection request signal CS3.

[0136] If the additional wireless communicator 26W detects the connection request signal CS3, the additional wireless communicator 26W of the additional electrical device 26 wirelessly transmits the connection signal CS4. If the wireless communicator 20W detects the connection signal CS4 ( Fig.15 ), controller 20C sets wireless communicator 20W to the second protocol connection state ST12 and stops transmitting the wireless signal using the first communication protocol CP1 (step S101). In the second protocol connection state ST12, wireless communicator 20W establishes a wireless connection between wireless communicator 20W and additional wireless communicator 26W using the second communication protocol CP2. In the case where the user uses additional electric device 26, controller 26C of additional electric device 26 controls display 26D to display information wirelessly transmitted from wireless communicator 20W using the second communication protocol CP2 in the second protocol connection state ST12.

[0137] like Figure 6 As shown, if the wireless connection established between wireless communicator 20W and additional wireless communicator 26W is disconnected, controller 20C sets wireless communicator 20W to notification state ST11 (step S102). In addition, if mode switch 20S receives additional user input UW2, controller 20C sets wireless communicator 20W to notification state ST11 (step S103).

[0138] If the additional wireless communicator 24W detects the connection request signal CS1 in the second notification AD2, the additional wireless communicator 24W of the additional electrical device 24 wirelessly transmits the connection signal CS2. Fig.14 ), controller 20C sets wireless communicator 20W to dual communication state ST13 (step S104). In dual communication state ST13, wireless communicator 20W establishes a wireless connection between wireless communicator 20W and additional wireless communicator 24W using second communication protocol CP2.

[0139] If wireless communicator 20W does not receive connection signals CS2 and CS4 during the third period PD3 ( Fig.13 ), controller 20C sets wireless communicator 20W to notification state ST14 (step S105). In notification state ST14, controller 20C controls wireless communicator 20W to wirelessly transmit information using first communication protocol CP1 and controls wireless communicator 20W to perform first notification AD1 using second communication protocol CP2 ( Fig.10 ).

[0140] If the additional wireless communicator 24W detects the connection request signal CS1 in the first notification AD1, the additional wireless communicator 24W of the additional electrical device 24 wirelessly transmits the connection signal CS2. If the wireless communicator 20W detects the connection signal CS2 (in the first time period PD1 or the second time period PD2 of the first notification AD1) Fig.11 or Fig.12 ), controller 20C sets wireless communicator 20W to dual communication state ST13 (step S106).

[0141] If the wireless connection established between wireless communicator 20W and additional wireless communicator 24W is disconnected, controller 20C sets wireless communicator 20W to notification state ST14 (step S107). If mode switcher 20S receives additional user input UW2 in notification state ST14 or dual communication state ST13, controller 20C sets wireless communicator 20W to notification state ST11 (step S108).

[0142] If the determination time DT11 has passed from the start of the dual communication state ST13, the controller 20C sets the wireless communicator 20W to the second protocol connection state ST15 (step S109). If the controller 20C detects the determination signal CS5 in the second protocol connection state ST15, the controller 20C sets the wireless communicator 20W to the dual communication state ST13 (step S110). Examples of the determination signal CS5 include an upshift control signal UC1, a downshift control signal DC1, an upshift control signal UC2, and a downshift control signal DC2. Examples of the determination signal CS5 may include other signals. If the mode switch 20S receives an additional user input UW2 in the second protocol connection state ST15, the controller 20C sets the wireless communicator 20W to the notification state ST11 (step S111).

[0143] If the wireless connection established between wireless communicator 20W and additional wireless communicator 24W is disconnected, controller 20C sets wireless communicator 20W to notification state ST16 (step S112). In notification state ST16, controller 20C controls wireless communicator 20W to perform first notification AD1 ( Fig.10 ).

[0144] If the wireless communicator 20W detects the connection signal CS2 ( Fig.11 or Fig.12), controller 20C sets wireless communicator 20W to the second protocol connection state ST15 (step S113). If mode switcher 20S receives additional user input UW2 in notification state ST16, controller 20C sets wireless communicator 20W to the notification state ST11 (step S114).

[0145] If controller 20C detects determination signal CS5 in notification state ST16, controller 20C sets wireless communicator 20W to notification state ST14 (step S115). After completing first notification AD1, if wireless communicator 20W does not receive information wirelessly transmitted from add-on electric device 24 or 28 using first communication protocol CP1 within determination time DT11, controller 20C sets wireless communicator 20W to sleep state (step S116).

[0146] If mode switch 20S receives additional user input UW2 in the sleep state, controller 20C sets wireless communicator 20W to notification state ST11 (step S117). If controller 20C detects determination signal CS5 in the sleep state, controller 20C sets wireless communicator 20W to notification state ST14 (step S118).

[0147] If the wireless communicator 20W does not detect the connection signal CS2 in the first period PD1 and the second period PD2 ( Fig.10 ), the controller 20C sets the wireless communicator 20W to the first protocol connection state ST17 after completing the first notification AD1 (step S119). In the case where the user uses the additional electric device 24, the controller 24C of the additional electric device 24 controls the display 24D to display information wirelessly transmitted from the wireless communicator 20W using the first communication protocol CP1 in the first protocol connection state ST17. In the case where the user uses the additional electric device 28, the controller 28C of the additional electric device 28 controls the display 28D to display information wirelessly transmitted from the wireless communicator 20W using the first communication protocol CP1 in the first protocol connection state ST17.

[0148] If mode switch 20S receives additional user input UW2 in first protocol connection state ST17, controller 20C sets wireless communicator 20W to notification state ST11 (step S120). If controller 20C detects determination signal CS5 in first protocol connection state ST17, controller 20C sets wireless communicator 20W to notification state ST14 (step S121). If wireless communicator 20W does not receive information wirelessly transmitted from additional electric device 24 or 28 using first communication protocol CP1 at determination time DT11, controller 20C sets wireless communicator 20W to sleep state (step S122).

[0149] like Figure 7 As shown, after the second communication mode starts, controller 20C sets wireless communicator 20W to notification state ST21. In notification state ST21, controller 20C controls wireless communicator 20W to perform second notification AD2 ( Fig.13 ).

[0150] If wireless communicator 20W detects connection signal CS4 ( Fig.15 ), controller 20C sets wireless communicator 20W to the second protocol connection state ST12 (step S201). If the wireless connection established between wireless communicator 20W and additional wireless communicator 26W is disconnected, controller 20C sets wireless communicator 20W to the notification state ST21 (step S202). Furthermore, if mode switcher 20S receives additional user input UW2, controller 20C sets wireless communicator 20W to the notification state ST21 (step S203).

[0151] If the wireless communicator 20W detects the connection signal CS2 ( Fig.14 ), controller 20C sets wireless communicator 20W to dual communication state ST23 (step S204). In dual communication state ST23, wireless communicator 20W establishes a wireless connection between wireless communicator 20W and additional wireless communicator 24W using second communication protocol CP2.

[0152] If wireless communicator 20W does not receive connection signals CS2 and CS4 in the third period PD3 ( Fig.13 ), controller 20C sets wireless communicator 20W to notification state ST24 (step S205). In notification state ST24, controller 20C controls wireless communicator 20W to perform first notification AD1 ( Fig.10 ).

[0153] If the wireless communicator 20W detects the connection signal CS2 ( Fig.11 or Fig.12 ), controller 20C sets wireless communicator 20W to dual communication state ST23 (step S206). In dual communication state ST23, wireless communicator 20W establishes a wireless connection between wireless communicator 20W and additional wireless communicator 24W using first communication protocol CP1 and second communication protocol CP2.

[0154] If the wireless connection established between wireless communicator 20W and additional wireless communicator 24W is disconnected, controller 20C sets wireless communicator 20W to notification state ST24 (step S207). If mode switcher 20S receives additional user input UW2 in notification state ST24 or dual communication state ST13, controller 20C sets wireless communicator 20W to notification state ST21 (step S208).

[0155] If the wireless communicator 20W does not detect the connection signal CS2 in the first period PD1 and the second period PD2 ( Fig.10 ), controller 20C sets wireless communicator 20W to the sleep state after completing first notification AD1 (step S219). If mode switch 20S receives additional user input UW2 in the sleep state, controller 20C sets wireless communicator 20W to the notification state ST11 (step S220). If controller 20C detects determination signal CS5 in the sleep state, controller 20C sets wireless communicator 20W to the notification state ST14 (step S221).

[0156] like Figure 8 As shown, after the third communication mode starts, the controller 20C sets the wireless communicator 20W to the second protocol connection state ST31. If the wireless communicator 20W does not receive the information wirelessly transmitted from the additional electric device 24 or 28 using the first communication protocol CP1 at the determination time DT11, the controller 20C sets the wireless communicator 20W to the sleep state (step S316).

[0157] If mode switch 20S receives additional user input UW2 in the sleep state, controller 20C sets wireless communicator 20W to the second protocol connection state ST31 (step S317). If controller 20C detects determination signal CS5 in the sleep state, controller 20C sets wireless communicator 20W to the second protocol connection state ST31 (step S318).

[0167] Second embodiment

[0168] The following will refer to Fig.17 and Fig.18 The operating system 210 including the wireless communication device 220 according to the second embodiment is described. The operating system 210 has the same structure and / or configuration as the operating system 10 except for the mode switch 20S. Therefore, the elements having substantially the same structure and / or configuration as those in the first embodiment will be numbered the same here, and for the sake of brevity, will not be described and / or shown in detail here.

[0169] like Fig.17 As shown, in wireless communication device 220, controller 20C does not use user input UW1 to set the communication mode of wireless communicator 20W. In this embodiment, controller 20C includes memory 220M configured to store mode information MD indicating a selected communication mode. Controller 20C is configured to set wireless communicator 20W to the selected communication mode based on mode information MD. The selected communication mode includes one of a first communication mode and a second communication mode. In this embodiment, the selected communication mode includes one of a first communication mode CM1, a second communication mode CM2, and a third communication mode CM3.

[0170] The controller 20C is configured to receive a mode command MC indicating the selected communication mode from the input device 229. The controller 20C is configured to store the mode command MC as mode information MD in the memory 220M if the controller 20C receives the mode command MC.

[0171] Examples of input device 229 include additional electric devices 24, 26, and 28. Each of additional electric devices 24, 26, and 28 wirelessly transmits a mode command MC indicating a selected communication mode to wireless communicator 20W.

Additional electric device 24, 26, or 28 wirelessly transmits a mode command MC indicating the communication mode selected using additional electric device 24, 26, or 28.

[0172] like Fig.18 As shown, controller 20C sets wireless communicator 20W to first communication mode CM1 (step S21). Controller 20C determines mode information MD (step S22). If mode information MD indicates first communication mode CM1, controller 20C sets wireless communicator 20W to first communication mode CM1 (steps S21 and S22). If mode information MD indicates second communication mode CM2, controller 20C sets wireless communicator 20W to second communication mode CM2 (steps S21 and S23). The program returns to step S22. If mode information MD indicates third communication mode CM3, controller 20C sets wireless communicator 20W to third communication mode CM3 (steps S21 and S24). The program returns to step S22.

[0173] The term "comprise" and its derivatives, as used in this article, are intended to be open terms that specify the presence of stated features, elements, components, groups, integers and / or steps, but do not exclude the presence of other unstated features, elements, components, groups, integers and / or steps. This concept also applies to words with similar meanings, such as the terms "have", "comprises" and their derivatives.

[0174] The terms “member,” “section,” “portion,” “part,” “element,” “body,” and “structure” when used in the singular can have the dual meaning of a single part or a plurality of parts.

[0175] Ordinal numbers such as "first" and "second" recorded in this application are merely identifiers and do not have any other meanings, such as a specific order and the like. In addition, for example, the term "first element" itself does not imply the existence of a "second element", and the term "second element" itself does not imply the existence of a "first element".

[0176] The term “a pair”, as used herein, can include a configuration in which the pair of elements have different shapes or structures from each other as well as a configuration in which the pair of elements have the same shape or structure as each other.

[0177] The terms "a," "one or more," and "at least one" can be used interchangeably herein.

[0178] Finally, terms of degree, such as "substantially", "about" and "approximately", as used herein, mean a reasonable amount of deviation of the modified term so that the end result is not significantly changed. All numerical values ​​described in this application can be interpreted as including terms such as "substantially", "about" and "approximately".

[0179] The phrase "at least one of," as used in this disclosure, means "one or more" of the desired options. As an example, the phrase "at least one of," as used in this disclosure, if the number of its options is two, means "only a single option" or "both of the two options." As another example, the phrase "at least one of," as used in this disclosure, if the number of its options is equal to or greater than three, means "only a single option" or "any combination of equal to or greater than two options." For example, the phrase "at least one of A and B" includes (1) A alone, (2) B alone, and (3) both A and B. The phrase "at least one of A, B, and C" includes (1) A alone, (2) B alone, (3) C alone, (4) both A and B, (5) both B and C, (6) both A and C, and (7) all of A, B, and C. In other words, the phrase "at least one of A and B" does not mean "at least one of A and at least one of B" in this disclosure.

[0180] Obviously, many modifications and variations of the present invention are possible in light of the above teachings.It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
