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](https://www.inpixon.com/technology/rtls)

Also see this latest research - [The outline of people’s bodies can be detected from Wi-Fi signals | New Scientist](https://www.newscientist.com/article/2356242-the-outline-of-peoples-bodies-can-be-detected-from-wi-fi-signals/)

- but no I'm not aware of a simple node to do the hard maths for you.
