Teltonika have an innovative range of advanced vehicle trackers that include Bluetooth. The tracker can scan for other nearby Bluetooth devices and send sensor data to a server.
There’s a getting started guide that explains how this is setup and provides screens showing how it works.
This allows not just for sensing telematics about the vehicles themselves but also about other assets or people. For example, if people carry beacons it’s possible to know who is driving or is in a vehicle. If you tag equipment usually stored in a vehicle you can determine where it is or if it is about to be removed from a vehicle. For temperature sensitive goods, such as medicines, you can continuously audit temperature compliance. It’s also possible to provide for location specific triggering, for example, producing work orders when a vehicle reaches an exact point whether or not there’s GPS coverage.
