Results are encouraging considering that even with an extremely heterogeneous hardware and software configuration, it was possible to get a high average precision. I discover a big problem which RSSI value is not accurate.

inquiry-with-rssi. You could also do the same thing directly from C using Bluez on linux. but the problem is that when i started doing my thesis project. 1,713 5 19 24 Add a comment 3 Answers Sorted by: 6 You can obtain RSSI during inquiry scan, without connecting to devices. The main contributions are: to determine how Bluetooth devices interact between them and how they differ when dealing with RSSI measures to collect data over controlled distances applying to it regression analysis to establish the RSSI - distance relationship to evaluate the basic trilateration techniques to produce a functional prototype for an indoor positioning system using Android devices. to make bluetooth RSSI more accurate Using Arduino Project Guidance ShadowSilver May 26, 2019, 8:55am 1 Hi guys, i am now in the part of thesis II defense. Second, with trilateration techniques, to establish the location of the receiver device in the experimental environment. Thereafter its a matter of sampling at your position and reverse lookup on the map. You need Bluetooth devices everywhere of course, and you have to sample RSSI beforehand to create an RSSI map of the area. First, to determine experimentally the relationship between RSSI and distance. Now youve got Bluetooth RSSI, you can do room accurate indoor location. Indoors positioning with Android, Bluetooth and RSSI. CABRERA-GOYES, Edwin and ORDONEZ-CAMACHO, Diego.
