The broadcast data packet carries data collected by the second Bluetooth device through its own motion sensor (eg, a gyroscope, a gravity sensor, an acceleration sensor, etc.).

[0043] The first Bluetooth device 010, after the pairing connection, plays the Bluetooth, and receives the broadcast data packet broadcast by the plurality of second Bluetooth devices 020.

The broadcast data packet carries the second Bluetooth The data collected by the device through its own motion sensor; the interval may be 20ms~10.24s

[0056] As a preferred example of the present invention, in order to reduce the number of candidate second Bluetooth devices and improve the security of the first Bluetooth device pairing connection, the embodiment of the present invention further includes:

[0057] the broadcast data packet carries a vendor custom field;

[0058] after the first Bluetooth device receives the broadcast data packet broadcast by the plurality of second Bluetooth devices, the first Bluetooth device filters out the second Bluetooth device issued by the vendor according to the vendor custom field carried by the broadcast data packet. . That is, the first Bluetooth device only needs to pay attention to the second Bluetooth device issued by the manufacturer, and excludes the second Bluetooth device that is not issued by the vendor through the vendor customization field carried in the broadcast data packet.

[0059] In step S202, the first Bluetooth device establishes a plurality of first motion curves according to data collected by the second Bluetooth device carried in the broadcast data packet through its own motion sensor, where each The two Bluetooth devices correspond to a first motion curve.

After determining that the motion curve of the second Bluetooth device conforms to the predetermined mode, the first Bluetooth device further needs to determine whether the change of the RSSI data is within a preset range and whether the RSSI data is always the largest.

[0069] In step S204, the first Bluetooth device initiates a connection request to the target second Bluetooth device to establish a connection.

[0070] In the embodiment of the present invention, the manner of establishing the connection may be that the user selects the target second Bluetooth device, and then connects through the justwork mode, or may be connected through an existing pairing manner, and is not limited herein.

[0104] Exemplarily, the first Bluetooth device does not match the second RSSI curve and the third RSSI curve, and/or the second RSSI curve does not match the second motion curve. Matching, disconnecting the connection with the target second Bluetooth device, and the pairing connection is terminated.

[0105] It should be noted that, the first Bluetooth device and the second Bluetooth device save the pairing connection information after each pairing connection is completed. If the first Bluetooth device and the second Bluetooth device detect the saved pairing connection information during the next pairing connection, steps S305-309 need not be performed. In addition, the above examples of the present embodiment are only for explaining the present invention, and do not limit the scope of protection of the present invention.

After the first Bluetooth device is connected to the target second Bluetooth device, the first Bluetooth device and the target second Bluetooth device can monitor the data of the other party and obtain the other party. The monitored data is self-generated, and corresponding curves (for example, RSSI curve, motion curve) are established according to the acquired data (for example, RSSI data, motion data), and the security of the connection is further confirmed by comparing the curves.
