The present invention relates to a BLE Bluetooth-based LED-lamp music rhythmic motion system, control method, and apparatus; said system comprises an LED lamp strip and a BLE Bluetooth module electrically connected to the LED lamp strip; the BLE Bluetooth module comprises a wireless receiving component and a BLE Bluetooth chip electrically connected to the wireless receiving component, the BLE Bluetooth chip being electrically connected to the LED lamp strip; the wireless receiving component receives LED blinking information sent by an external sound source device, and sends the LED blinking information to the BLE Bluetooth chip, the LED blinking information being generated by the external sound source device according to frequency spectrum information of a song currently being played; according to the LED blinking information, the BLE Bluetooth chip controls the LED lamp strip to blink. In the embodiments of the present invention, a BLE Bluetooth module is used to receive the LED blinking information sent by the external sound source device, and the LED lamp strip is controlled to generate a light effect corresponding to a song currently played by the external sound source device; thus the wiring limitations between the external sound source device and the LED lamp strip is effectively prevented and user experience is improved.
