Loko operates with 2 units: The Ground unit (receiver), and the Air unit (transmitter). The Air unit transmits navigation data to the Ground unit at a pre-configured time interval, and the Ground unit transmits the received data to a smartphone app via Bluetooth. The app automatically shows the location of any Loko Air modules on a 2D map. By giving a uniqe ID to each Loko Air unit, up to 30 Air units can pair with a single Loko Ground unit.
