FIG. 1 is a schematic diagram of a Bluetooth low energy reminder system according to an embodiment of the present invention, please refer to FIG. 1 . The Bluetooth low energy reminder system may include a setting device 102 and Bluetooth low energy devices 104 , 106 , 108 . The setting device 102 can be, for example, a handheld device, such as a mobile phone, a tablet computer, or other electronic devices that can provide Bluetooth low energy connections. The Bluetooth low energy devices 104, 106, 108 can be, for example, Bluetooth low energy Items with power consumption tags. The setting device 102 can establish a Bluetooth low energy connection with the Bluetooth low energy devices 104, 106, 108 to set the Bluetooth low energy devices 104, 106, 108 so that the broadcasts sent by the Bluetooth low energy The packet includes group information, for example, the group information can be recorded in the payload field of the broadcast packet, but not limited thereto.

The group information may include identification data of the Bluetooth low energy devices 104, 106, 108, so that the Bluetooth low energy devices receiving the broadcast packet know whether the device sending the broadcast packet is a Bluetooth low energy device belonging to the same group. For example, each of the Bluetooth low energy devices 104, 106, 108 can perform the broadcast action and the listening action in turn in a peripheral mode during the preset confirmation period, that is, send a broadcast packet and listen to the rest of the Bluetooth low energy devices. An action of broadcasting packets that respond after receiving broadcasting packets, wherein both the broadcasting packets sent in the broadcasting action and the broadcasting packets received in the listening action include group information, and both can be non-connected broadcasting packets. At the end of the confirmation period, each Bluetooth low energy device can judge whether other Bluetooth low energy devices in the group information except itself have responded to the broadcast packet according to the identification data in the received broadcast packet. The identification data of all other Bluetooth low energy devices in the information can provide a reminder signal to remind the user that a Bluetooth low energy device is no longer within the transmission range of the broadcast packet.

For example, the reminder mechanism of the Bluetooth low energy reminder system may be shown in FIG. 2 . After the setting device 102 establishes a Bluetooth low energy connection with the Bluetooth low energy devices 104, 106, and 108, it can send setting commands CMD1, CMD2, and CMD3 to the Bluetooth low energy devices 104, 106, and 108 respectively to set the Bluetooth low energy devices. The power consumption devices 104, 106, and 108 make the broadcast packets sent by the Bluetooth low energy devices 104, 106, and 108 include group information. In this embodiment, the group information may include the Bluetooth low energy devices 104, 106, and 108 identification data. After completing the setting of the broadcast packet, the setting device 102 can send a start control signal ST1 to the Bluetooth low energy devices 104, 106, and 108 to start the Bluetooth low energy devices 104, 106, and 108 to start taking turns in the peripheral mode during the confirmation period T1 Execute the broadcasting action and listening action described above. For example, in this embodiment, the Bluetooth low energy device 104 may first perform a broadcast action to send the broadcast packet BR1, and at this time the Bluetooth low energy devices 106 and 108 perform a listening action to receive the broadcast packet BR1 from the Bluetooth low energy device 104, And send broadcast packets RBR1 and RBR2 in response to the broadcast packet BR1 respectively. The Bluetooth low energy device 104 performs the listening operation after performing the broadcasting operation, so as to listen to the broadcast packets RBR1 and RBR2 responded by the Bluetooth low energy devices 106 and 108 .

The Bluetooth low energy device 104 can confirm whether to receive the broadcast packets RBR1, RBR2 of the Bluetooth low energy devices 106, 108 according to the group information set by the setting device 102, if the broadcast of the Bluetooth low energy devices 106, 108 has been received Packet RBR1, RBR2, then do not send reminder signal, and if do not receive the broadcast packet sent by any one of bluetooth low power consumption device 106,108, bluetooth low power consumption device 104 can send out reminder signal, to remind user bluetooth low power consumption At least one of the consumption devices 106 and 108 is no longer within the transmission range of the broadcast packet.

Further, the identification data in the above group information may include, for example, a group identification code (such as 2353, but not limited thereto) and a preset value (in this embodiment, the preset value may be, for example, 2), The Bluetooth low energy device 104 can judge whether the Bluetooth low energy device sending the broadcast packet belongs to the same group of Bluetooth low energy devices according to whether the received broadcast packet includes the group identification code, and determine whether the Bluetooth low energy device sending the broadcast packet When the low-power devices belong to the same group of Bluetooth low-power devices, the count value is accumulated, for example, when it is determined that the received broadcast packet includes the group identification code 2353, the count value is increased by 1. It is worth noting that the broadcast packet of the Bluetooth low energy device also includes other device identification information, such as address information, but it is not limited to this. The Bluetooth low energy device 104 can, for example, determine whether to receive repeatedly based on the device identification information Advertisement packets to the same Bluetooth low energy device to avoid double counting.

If the accumulated count value (eg 2) is equal to the preset value, it means that the Bluetooth low energy device 104 has received other Bluetooth low energy devices (such as Bluetooth low energy devices 106, 108) in the group information except itself, and There is no need to send a reminder signal. Conversely, if the cumulative count value (for example, 1) is less than the preset value after the confirmation period T1 ends, it means that the Bluetooth low energy device 104 has not received all other Bluetooth low energy devices in the group information except itself. The Bluetooth low energy device 104 can send a reminder signal to remind the user that the Bluetooth low energy device is no longer within the transmission range of the broadcast packet.

In some embodiments, the identification data in the group information may also include, for example, different identification names corresponding to each Bluetooth low energy device 104, 106, 108, such as the identification of the Bluetooth low energy device 104, 106, 108 The names can be wallet, key, passport respectively, but not limited to this. The Bluetooth low energy device 104 can determine whether the broadcast packets of all other Bluetooth low energy devices belonging to the same group have been received according to the identification name included in the received broadcast packet. For example, if you have received a wide packet with the identification name of a key and a passport, you do not need to send a reminder signal, and if you only receive an advertisement packet for the key or passport at the end of the confirmation period T1, then send a reminder signal to remind the user to have a Bluetooth low-key The power consumption device is no longer within the transmission range of the broadcast packet.

By analogy, the Bluetooth low energy device 106 also performs the broadcast action and listening action during the confirmation period T1 in the same way, that is, sends the broadcast packet BR2 and receives the broadcast packets RBR3 and RBR4 from the Bluetooth low energy devices 104 and 108. , and judge whether to send a reminder signal according to the received broadcast packet. In addition, the Bluetooth low energy device 108 also performs the broadcast action of sending the broadcast packet BR2 and the listening action of receiving the broadcast packets RBR5 and RBR6 responses from the Bluetooth low energy devices 104 and 106 during the confirmation period T1 in the same manner, and according to the received broadcast packet to determine whether to send a reminder signal. In this way, the group information is set in the broadcast packets of the Bluetooth low energy devices 104, 106, 108, so that the Bluetooth low energy devices 104, 106, 108 perform the broadcast action and the listening action in turn during the confirmation period T1, and during the confirmation period T1 At the end, it is determined whether to provide a reminder signal based on whether the identification data of all other Bluetooth low-power devices in the group information are received, so that even if the Bluetooth low-power devices 104, 106, and 108 are in peripheral mode, they cannot respond to non-connected devices. When the connection is initiated by the broadcast packet, the reminder function can also be executed according to the group information, which can greatly improve the practicability of the Bluetooth low energy broadcast device.

It is worth noting that the setting device 102 can control the Bluetooth low energy devices 104, 106, and 108 to enter the confirmation period T1 periodically through the activation control signal, and perform the broadcasting action and the listening action in turn during each confirmation period T1, so as to continuously monitor Each other's location, confirm that the Bluetooth low energy devices 104, 106, 108 are all within the transmission range of each other's broadcast packets. In some embodiments, the setting device 102 can also control the Bluetooth low energy devices 104, 106, and 108 to only enter the confirmation period T1 once through the activation control signal, and stop performing the broadcasting action and the listening action in turn after the confirmation period T1 ends, and wait for The user operates the setting device 102 again to send the activation control signal to enter the confirmation period T1 again, which can reduce power consumption and prolong the use time of the Bluetooth low energy devices 104 , 106 , 108 . In addition, although the above-mentioned embodiment uses three Bluetooth low energy devices 104, 106, 108 as an example to illustrate the Bluetooth low energy reminder system, the number of Bluetooth low energy devices is not limited to this. In other embodiments Among them, the Bluetooth low energy reminder system may also include different numbers of Bluetooth low energy devices, such as 2 or more than 4 Bluetooth low energy devices.
