Long Range Proximity Detection of Bluetooth Low Energy Devices. Distance Estimation using Signal Strength RSSI.
Fanstel BU840XE Unit
Fanstel BU840XE Unit is programmed with firmware that scans for bluetooth device MAC addresss and RSSI, forwards that information onto a USB-Serial Port. A python script on the other end recieves the data and uses a filter and algorithim to deterine approximate distance from the RSSI. The software is able to determine whether a device is stationary, moving away or moving toward you.
