Bluetooth Low Energy based Indoor Positioning System using ESP32

As of now, the Global Positioning System (GPS) is the leading outdoor positioning system, However, indoors, GPS is a flop because the signal does not penetrate easily through solid objects and there is no line-of-sight. Since GPS is unreliable in indoors the alternative technology emerged called Indoor Positioning System (IPS). Indoor positioning is accomplished using several techniques and devices. The proposed model prefers to use Bluetooth Low Energy-based positioning system. This paper focuses on implementing BLE based indoor positioning using ES P32-Node MCU.
