Of course your going to have to use an RC filter from the RSSI output to the OSD input, I suggest a 1K and 10uF. And then your probably going to only get ~60% of full scale on the OSD (RSSI is 3.3v max, your OSD is probably 5v), what I did was add a trimmer pot after the RC filter to adjust the 100% signal strength down to read 50% on the OSD ...

The project employed Particle Xenon boards as Bluetooth beacons, and the RSSI values read by a Particle Argon were used in a Kalman filter for localisation. If the Argon board detected a non-beacon RSSI within 1.5m of the device, it would record the time in contact until the device was out of range.

Jan 26, 2007 · The RSSI values that I was getting between two nodes were stronger when the nodes were 50 meters away than when they were 40 meters away. I'm more of a programmer than an RF engineer, but some signal re-enforcement from multi-path or something in the hallway was causing very strange results.

The availability of RSSI in the motes help us to estimate finding the location in terms of time and space. And then sensor nodes deliver the coordinate location to base station through neighboring sensor nodes. The availability of RSSI in the sensor networks made us to try an attempt to identify the locations of unknown sensor nodes.
Firstly, the observed position is estimated by a moving object localization algorithm based on Received Signal Strength Indication (RSSI). Then, the estimated position is filtered by a Kalman filter in order to obtain a smoothed trajectory of moving objects movement.
Standard Kalman filtering can be used to approach this problem when the sensor noise is assumed to be Gaussian. We'll use robust Kalman filtering to get a more accurate estimate of the vehicle state for a non-Gaussian case with outliers.

It was during a visit of Kalman to the NASA Ames Research Center that he saw the applicability of his ideas to the problem of trajectory...
The basic Kalman filter is limited to a linear assumption. More complex systems, however, can be nonlinear. The nonlinearity can be associated either with the process model or with the observation model or with both. The most common variants of Kalman filters for non-linear systems are the Extended Kalman Filter and Unscented Kalman filter.
