Facilino Bluetooth more opcion

Hello I am looking for the aix of facilno or Bluetooth but that in turn has more options such as through Bluetooth measure distance and what to do with it ... Does anyone know that aix exists to use in the inventor app

There was an extension developed by PolyU in Hong Kong that used RSSI to approximate the position of a phone among multiple BLE devices. It's possible there may be others that try to estimate distance based on RSSI. However, the measure itself is relatively noisy and affected by any objects transiting the space between the devices (e.g., a person).

Hi! Do you have the link?
