I have buy the assest but cannot works

Sadly, we don’t provide any official Unity3D plugins for our iOS Indoor Location SDK, and I’m also not aware of any 3rd party options in that regard.

At this time, you’d either need to write the bridge between Unity3D and Indoor SDK yourself, or use the regular iBeacon plugin to do your own, rough indoor positioning. As in, you can use the iBeacon plugin to detect the UUID, major, and minor of beacons nearby, and infer the position based on that.
