Bluetooth Activity Markers
There are 2 types of bluetooth activity markers:
- Static
- Dynamic
Static Bluetooth Activity Marker
In locations where access to 5V is challenging, traditional Bluetooth Beacons can be used to provide a Static (broadcasting a signal that changes LESS than once every year) bluetooth signals.
Daxia DX-CP28
