Systems and methods for controlling target device

The invention relates to a system and method for controlling a target device. The system comprises a transmitting device and a receiving device. The transmitting apparatus includes: a switching unit capable of switching between two or more states; and a low-power Bluetooth module configured to transmit a data packet via the broadcast channel in response to the switching unit being switched, wherethe data packet includes an identification bit and a data bit, the data bit including a MAC address of the target device. The receiving device comprises a memory and a pairing module, wherein the pairing module is configured to monitor a broadcast channel to receive a data packet; judging whether the identification data in the identification bit in the data packet is correct or not; in response tothe correct identification data, analyzing the MAC address from the data bit; and storing the MAC address in a memory. 本发明涉及用于控制目标设备的系统和方法。该系统包括发射装置和接收装置。发射装置包括：切换单元，切换单元能够在两个或更多个状态之间切换；和低功耗蓝牙模块，低功耗蓝牙模块被配置成响应于切换单元被切换而经由广播信道发射
