Multiple BLE to calculate the distance

[Geaper]

Hello. I wanted to use a receiver on a quadcopter and some becons nearby(+-5 meters). Is it possible to determine the distance IN REAL TIME to the drone?

Hi,

You can get a rough estimate on the distance using RSSI, but it will probably have to low accuracy (maybe ± 2 – 5 meters) for your application. So you will have to look into other technologies if you need accurate distance measuring.
