In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the invention.

 [0029] In order to explain the technical solutions described in the present invention, the following description will be made by way of specific embodiments.

[0030] Please refer to FIG. 1, which is a flowchart for implementing a method for confirming a pairing connection of a terminal device according to an embodiment of the present invention, which mainly includes the following steps:

[0031] Step S101, the first Bluetooth device acquires the following at least one set of data according to the preset inter-frame interval: the RSSI data of the Bluetooth signal of the target second Bluetooth device, and the motion sensor of the first Bluetooth device The collected data, the RSSI data of the Bluetooth signal of the first Bluetooth device monitored by the target second Bluetooth device according to the preset interval, and the target second Bluetooth device according to the preset time Data collected by a motion sensor carried by the target second Bluetooth device.

 [0032] In the embodiment of the present invention, the target second Bluetooth device is a second Bluetooth device connected to the first Bluetooth device. The first Bluetooth device and the target second Bluetooth device are terminal devices having a Bluetooth function (preferably Bluetooth Low Energy (BLE) function with Bluetooth 4.0 protocol), such as a smartphone, a tablet, and the like.

 [0033] Illustratively, after the first Bluetooth device establishes a connection with the target second Bluetooth device, the target second Bluetooth is at a certain interval (for example, 7.5ms~4s, preferably 20ms). The device needs to send a heartbeat packet that maintains the connection to the first Bluetooth device, and the first Bluetooth device needs to respond.

 [0034] Since the first Bluetooth device and the target second Bluetooth device transmit and receive the heartbeat packet at each of the time intervals, the RSSI data is updated once every time interval. Based on this, the first Bluetooth device and the target second Bluetooth device in the embodiment of the present invention can confirm the connection by monitoring the R SSI data of the Bluetooth signal of the other party and acquiring the RSSI data of the Bluetooth signal detected by the other party. safety.

 [0035] In another example, the first Bluetooth device and the target second Bluetooth device each have a motion sensor (eg, a gyroscope, a gravity sensor, an acceleration sensor, etc.), the first Bluetooth device and the second The Bluetooth device can also collect its own motion data through its own motion sensor, and confirm the security of the connection by acquiring the collected motion data.

 [0036] Step S102: The first Bluetooth device establishes a corresponding curve according to the acquired data.

 [0037] Illustratively, the first Bluetooth device establishes a second RSSI curve according to the monitored RS SI data of the Bluetooth signal of the target second Bluetooth device, according to the acquired RSS signal of the Bluetooth signal of the first Bluetooth device. The I data establishes a third RSSI curve;

 [0038] Further, the method may further include:

 [0039] The first Bluetooth device acquires data collected by its motion sensor according to the preset inter-turn interval, and establishes a second motion curve according to the data.

The acquired data establishes a fourth motion curve.

[0041] It should be noted that, in the embodiment of the present invention, the curve may be in the form of a distance (ordinate) - an inter-turn (abscissa) curve, a velocity (ordinate) - an inter-turn (abscissa) curve, or an acceleration. (ordinate) - the form of a curve such as the daytime (abscissa).

 [0042] Step S408: The first Bluetooth device determines whether the established curve meets the predetermined mode. If the determination result is “Yes”, step S409 is performed; if the determination result is “No”, step S410 is performed.

 In the embodiment of the present invention, the curve conforming to the predetermined mode may be that the variation range of the curve is within a preset range and/or the period of change of the curve conforms to a specific rule or the like.

 [0044] Step S409, confirming the connection.

 [0045] Step S410, disconnecting the connection with the target second Bluetooth device.

 [0046] It should be noted that, in this embodiment, determining whether the motion curve meets the predetermined mode may be applied to a Bluetooth device motion or a scene in which two Bluetooth devices perform the same motion; determining whether the RSSI curve conforms to a predetermined mode. Can be applied to a scene where a Bluetooth device is moving or two Bluetooth devices are doing the same motion.

 After the first Bluetooth device establishes a connection with the target second Bluetooth device, the first Bluetooth device and the target second Bluetooth device may monitor the data of the other party and obtain the other party. Detecting the own data, and selecting at least one set of data from the obtained data (for example, RSS data, motion data), establishing a corresponding curve according to the selected data, and determining whether the established curve conforms A predetermined mode to further confirm the security of the connection.

[0051] the first Bluetooth device determines whether the changed change of the RSSI data is within a preset range;

[0052] If no, the connection with the target second Bluetooth device is broken.

[0053] This example can be applied to the following scenario: a first Bluetooth device and the target second Bluetooth device are in phase The same motion, for example, the first Bluetooth device is held in the hand, and the target second Bluetooth device is brought on the wrist. Since the distance between the first Bluetooth device and the target second Bluetooth device does not change, the change of the RSSI data is close to zero.
