Indoor Navigation Positioning rssi

If we have more than 4 bluetooth ble beacons and we have placed it in a room on 4 different walls, using rssi value can we find the user position inside a room , having a mobile app scanning all 4 beacons rssi ?

Is there any working library which can be used to accomplish this !!

I've seen similar solutions, but most use Wi-Fi instead of Bluetooth (which is easily blocked by walls, furniture, and other obstacles): Real-Time Location Systems & Hardware - Inpixon RTLS
