Method and device for controlling BLE Bluetooth based on capacitive sensor

The invention provides a method and device for controlling BLE Bluetooth based on a capacitive sensor. The method comprises the following steps that: a moving object enters an induction area of the capacitive sensor, such that the pass-back capacitance of the capacitive sensor is changed; then, a Bluetooth module inducts the capacitance change condition through itself; the Bluetooth module starts Bluetooth broadcasting or scanning while inducting that the capacitance is in a fluctuation change state; the moving object leaves the induction area of the capacitive sensor, such that the pass-back capacitance of the capacitive sensor is equal to a constant number; and the Bluetooth module closes Bluetooth broadcasting or scanning while inducting that the capacitance is in a constant state. According to the invention, the Bluetooth data communication security is increased; and the method and the device have better popularization and application prospects.
