Each RSSI field is the average of one hundred measures done. The visualization shows the relation between the RSSI and the distance from a specific BLE device
Counting the number of BLE Devices around the ESP32 and classifyig them into 3 different fields according to the value of their RSSI.
ESP32 scans a target BLE device to get its RSSI and estimates the distance of the device
