Get unique identifier for beacon in iOS?

I have Jaalee beacons. I tried to connect to them from various phones via various ways including both ibeacon and core bluetooth but all the time I get new identifiers. It means if I don't move and try iphone1 then I get set1 of beacon uuids, then I try iphone2 and get set2, then I try iphone1 and get set1 again. And there are no element which belongs to set1 and set2 simultaneously.

I tried other variables and properties but it seems all of them are common for beacons or different on various iOS devices. How to solve this issue?

Solved. For my case (Jaalee beacons) I should perform a lot of actions in the following order:

  1. scan for beacons
  2. store beacon I found into a dictionary and request its service list
  3. if I get service list then I request characteristic list
  4. if I get characteristic list then I request value for characteristics I need
  5. If all the previous steps are successful then I get beacon proximityUUID, major and minor which are all in common represent "unique identifier"

All these steps are called asynchronously. Additionally I should delete from dictionary of beacons I found on disconnecting from them. I should also check on some steps if a beacon is still connected.

UUID which is "too unique" I use for a key in a dictionary because the beacon objects are called asynchronously.

I suspect the reason you are seeing a different UUID each time is because you are using CoreBluetooth, and CoreBluetooth does not give you the beacon's ProximityUUID -- it gives you the Bluetooth session UUID which is randomly generated in iOS. See here for details.

If you want a tool to figure out the ProximityUUIDs and you have a Mac, you might try ScanBeacon ($10) or the free Beacon CLI.
