1. A wireless control method, applied to a Bluetooth Low Energy (BLE) device as a control terminal, the BLE device communicating with at least one other BLE device through a Bluetooth link, the method comprising:
s01: receiving positioning packets transmitted by the at least one other BLE device at a preset time interval;
s02: obtaining a first relative movement trajectory of the at least one other BLE device with respect to the BLE device according to the received positioning packets in combination with a Bluetooth direction positioning technology, wherein the first relative movement trajectory is a valid trajectory in a preset trajectory database determined according to a predetermined mapping relationship;
s03: determining a control function corresponding to the first relative movement trajectory according to the predetermined mapping relationship;
s04: transmitting a corresponding control instruction to the at least one other BLE device according to the control function to execute the control function;
wherein the BLE device further communicates with a third BLE device through the Bluetooth link, and the method further comprises:
after the step s04,
s05: periodically receiving the positioning packets transmitted by the third BLE device to track a second relative movement trajectory of the third BLE device with respect to the BLE device;
s06: determining whether the first relative movement trajectory is the same as the second relative movement trajectory and both correspond to a preset movement trajectory; when the first relative movement trajectory is the same as the second relative movement trajectory and both correspond to a preset movement trajectory, performing a step s07;
s07: transmitting a preset control instruction to the at least one other BLE device such that the at least one other BLE device establishes a control relationship with the third BLE device;
s08: transmitting control information corresponding to the at least one other BLE device to the third BLE device, such that the at least one other BLE device establishes the control relationship with the third BLE device.
