Indoor positioning with bluetooth low energy: a preliminary system design and results

This study explores indoor positioning in enclosed environments using Bluetooth Low Energy technology. A system based on two Thunderboard Sense 2 beacons and a Nordic nRF52840-DK device has been proposed. The positioning method relies on signal characteristics to estimate the location of an object. Related research has been reviewed, and the technical implementation of the preliminary system has been presented. The results demonstrate the potential of Bluetooth Low Energy for accurate and energy-efficient indoor positioning and provide a basis for further experimental validation.
