Suppose, I've 3 beacons in a room. When a person entered into that room. The Android App finds out those 3 beacons with different ranges like 1st beacon is in Immadiate range, 2nd beacon is in near range and 3rd beacon is in Far range.
So, how can we find out the distances of those 3 (i.e in Meters or Feets) ?
And, Which beacons Content will get in App? (1 - Immadiate or 2 - Near or 3 - Far).
