The aim is to create an WiFi RSSI map for my college, which will result in a diagram of strongest and weakest wireless zones.
An ESP12-E is used for rapidly logging WiFi RSS values which are then sent to an Android phone via HC-05 bluetooth.
On the android phone, latitudes and longitudes (courtesy of Google's location API) for each RSSI data-point are compiled into a .csv file.
The .csv file has to be then processed accordingly keeping in mind the relative layout of the assessed region.
