Abstract: Systems, devices, and methods for motion-based beacon advertisement are disclosed. A motion detector (e.g., request to enter detector) includes a motion sensor, a first Bluetooth® radio that operates in a beacon mode, and a controller that executes instructions. The instructions cause the controller to detect a motion event via the motion sensor, initiate a timer for a predetermined time in response to the detected motion event, broadcast a beacon message in response to the detected motion event via the Bluetooth® radio, and terminate the broadcast of the beacon message upon expiration of the timer.
