Abstract

The invention discloses a BLE (Bluetooth Low Energy) broadcast sending and receiving method, device and system, and the method comprises the steps: respectively adopting a random algorithm in the information interaction process of broadcast equipment and scanning equipment: the broadcast equipment selects a random broadcast event through the random algorithm to directly send scanning response data; after scanning request data are received in other broadcast events, scanning response data are sent; and the scanning equipment selects a random broadcast event through a random algorithm to send scanning request data, and waits for receiving scanning response data in other broadcast events. Compared with the prior art in which scanning request data are ignored to directly send and receive scanning response data, the method and the device have the advantages that the probability of scanning request collision can be reduced, the probability of successful completion of active scanning is improved, power consumption generated by broadcasting equipment and scanning equipment in information interaction is reduced, and the service life of the broadcasting equipment and the scanning equipment is prolonged. The service life of the equipment is prolonged, and the broadcasting cost is saved.
