It seems neat! Not sure, though, how much better it is than a whistle or noise maker, given its range. It does make noise when activated, so maybe the BLE can be used when the sound isn’t as useful.
Signal range
BLE range: typically 10-30 meters indoors, further outdoors, limited by rubble and building materials.
