The embodiment of the invention discloses a Bluetooth two-way communication method which comprises the following steps: a first Bluetooth module in a tire pressure monitoring module actively sends a first radio frequency signal in a broadcast mode; and the control module is used for receiving a second radio-frequency signal corresponding to the first radio-frequency signal sent by a second Bluetooth module in the host module in a broadcast mode within a preset time, and controlling the working state of the tire pressure monitoring module according to whether the second radio-frequency signal is received within the preset time or not. According to the Bluetooth two-way communication method, channels do not need to be changed, so that electricity is saved, the requirement for the control module of each Bluetooth module is lower, and cost is saved.

    依据本发明的实施例揭露了一种蓝牙双向通讯方法,所述蓝牙双向通讯方法包括胎压监测模块中的第一蓝牙模块主动以广播模式发送完第一射频信号后,在预定时间内接收主机模块中第二蓝牙模块以广播模式发送的与所述第一射频信号对应的第二射频信号,并根据是否在预定时间内接收到所述第二射频信号,控制所述胎压监测模块的工作状态。在本发明中的蓝牙双向通讯方法不用变换频道,因而比较省电,并且对每个蓝牙模块的控制模块的要求更低,节约了成本。
