The present invention provides a beacon-based broadcast method and a Beacon device. The method comprises: a Beacon device transmits a first broadcast to a fixed area according to a first sampling frequency; while the Beacon device transmits the first broadcast to the fixed area according to the first sampling frequency, the Beacon device replaces to form a scanning response (SCAN_RSP) broadcast according to the first sampling frequency, wherein the SCAN_RSP broadcast carries a second device identifier and customized data of the Beacon device; and each time after the Beacon device receives a SCAN_REQ, the Beacon device transmits the currently formed SCAN_RSP broadcast to the fixed area when a next sampling time point corresponding to the first sampling frequency comes, so as to allow a Bluetooth main device in the fixed area to scan and acquire the SCAN_RSP broadcast according to a second sampling frequency. The scheme effectively solves the technical problem that the data transmission efficiency of an existing Beacon device is low.
