May I ask about how to adjust beacon's working range

I'm Tommy, a master student in Austria. I am going to adjust beacon's working range but I don't know how to do this@ In Estimote App, it needs 'Apple token', which I'm not clear what it is..Is it possible to adjust it by coding rather than using this APP?

By the way, I want to use the distances to three beacons to calculate current position coordinates, is there good method to call@?

Thank for any help.

As for adjusting range, you can do it via setting the broadcasting power settings either with our mobile app or the Estimote SDK:
