I have to create an indoor navigation system to navigate visually impaired people in an art exhibition. Since the exhibition area is quite large and has more rooms and corridors, I wanted to use multiple ESP32 as BLE beacons and an Android device with a Unity application to detect its relative position through RSSI and navigate users with vibrations.
It's my first time working on such project and I was wondering if anyone has any suggestion about how to approach this project, or if this is even feasible (with this setup).
Any opinion is highly appreciated!
