As an asynchronous receive option, a scanning mode will allow moving nodes to pass their IDs and data packet without association. A typical application would be a water station in a running race. As runners pass by, their IDs and performance totals would transmit to a receiver at the station. The application at the station could respond to the runner, sending their position and the nearest competitor’s or teammate’s position in the response. Background scanning channel is a second asynchronous option, which scans much like a search instead of being always on, allowing other open channels to exist on that radio. No association is required in this channel option as the extended data operation passes Channel ID, optional time and RSSI data and the traditional 8 byte ANT data packet through to the MC automatically. A good example of this would be a display that moves from one network to another and rather than opening up receive channels for every sensor possible, it will monitor in the background for existing devices. The application will then only need to open channels for the previously discovered device types. An implementation of this option could be a bike computer moved from bike to bike.
