I want to create a small app using flutter that tracks my location inside my 100x100m apartment. I am interested in creating an indoor navigation app for various places, but at the moment, I lack the knowledge on how to accomplish it, therefore setting the scope of the app to be very small and very local for testing purposes.
From what I could gather, there is three primary technology to use BLE(Bluetooth Low Energy),Wi-Fiand UWB(Ultra-wideband). I am planning to useWi-Fi as it seems to be the most straight forward way, but I could be wrong on this matter.
The issue is that I don't know where to start learning about this or what kind of tools I would need to create the map for the house. If anyone could point me in the right direction, I would be very happy and appreciative.
I imagine you would use use beacons placed at known positions and use RSSI as analogue to distance and do something similar to GPS where you draw spheres around each beacon and where it all intersects is where your device is.
There's quite a few research papers if you search indoor localization using rssi measurements
