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).
As you can check in samples
So For your point 2
Yes those discovered beacons are sorted according to distance by estimote sdk
For your point 1
You need to check the SDK samples for that I just want to tell you that yes it is possible as Estimote Sample app shows the distance between beacon and device
