Indoor navigation with Iphone 12 pro + airtags

Hi, I'm a computer engineering student and I'm working on my end-of-degree project. For part of this project I need to be able to locate my position within a room of about 5x5m with an error of +-50cm.

I think with the airtags placed at known locations like 3 corners of the room and with the distances to those 3 airtags it would be possible to triangulate my position with sufficient precision.

For this I think I have to use the Nearby Interactions framework but I can't find how to work with airtags only with other iphones (Peer session)

Could someone guide me?
