Beacon has a pretty specific meaning in the BLE world. A BLE beacon sends a broadcast out every now and then* that says “hey I exist, here’s my ID”. Another device can scan for these “advertisement” and do something when a particular kind of device is detected. An example use case is a museum app displaying info to a user when they walk up to a particular exhibit. * the interval can be set from 10ms to ~10s. The radio can be turned off in between advertisements, which is where the “LE” part comes from.
