Is it possible to implement BLE-like proximity service with BL 3.0 on Android?

If I make one device (e.g. Android tablet) indefinitely discoverable and make a second one (e.g. phone with BL 3.0 support) search for devices, it seems like I'll be able to extract server device name (http://ift.tt/1fY8FKC). By device name, I can deduct where in the world is the second device. What is wrong with sucn an approach? (I'm completely new to Android, just validating feasibility of some idea).

The problem with BLE is - 70% of android devices still have OS version < 4.3.
