Gw-http-box nodejs calculate distance in meters?

I am using gw-http-box nodejs example with JSON and I would like to know if i can calculate the distance in meteres to my ibeacon from my AB BLE Gateway v4.


First, using RSSI to calculate distance is very inaccurate.

You can check the topic for calculate distance How to find beacon distance by the received RSSI?

Okey, thanks and is there any way to have something more precise?
