We have collected some data from a number of BLE beacons in an indoor environment and we would like to see if we can use that for positioning.
We collect RRSI values which can be simply converted into a range (distance value)
using the obtained range values from multiple BLEs with known location we can perform triangulation and estimate the exact location of the device how ever some smoothing is required.
Do you have any experience with KALMAN filter or Gaussian Process?
We require all the implementation in JAVA
