Indoor Positioning / Triangulation

Hi Everybody, we know that ibeacons measure only distance, they don’t say in which direction. So I was assigned to implement triangulation method into April Beacon Demo project. I searched on Stackoverflow( user: hrskrs, ). This page is recommended by @ aprilpea

I searched there and hrskrs’s approach is so logical. And I want to implement his code into April Beacon Demo project. Anyone can help me please, it would be appreciated a lot. Thanks in advance !!
