I'm looking for guidance and suggestions on what is the best way to design a system that will be aimed at people spending a long time, e.g., all day, in a large store, and wanting to know what parts they visit. Primarily targeting an Android app at this stage.
One way would be to assign all the beacons the same UUID and major number, create a region and start a background service to monitor it. Then you onEnteredRegion() and onExitedRegion() when the person enters/exits. Is that all you get? Or does onEnteredRegion() get called multiple times as the mix of beacons detected changes? If not, how do you get further information as they move about? Use onEnteredRegion() to launch a foreground app for ranging beacons, and working out from proximity where the person is?
Another way would be to define multiple regions, one for each department say. This would require BeaconManager to simultaneously monitor multiple regions. Is this possible? Then presumably the first argument to onEnteredRegion() and onExitedRegion() would let you work out where the person is.
What would be the better approach?
