Angle-of-arrival (AoA) measurements of a Bluetooth Low Energy (BLE) beacon recorded with three ceiling-mounted Silicon Labs BRD4185A antenna-array receivers in an office laboratory of the Institute of Theoretical and Applied Informatics, Polish Academy of Sciences (Gliwice, Poland), in September-October 2021. The beacon (Silicon Labs EFR32BG22) was moved by a stepper-motor swivel arm along three semicircular trajectories with three movement patterns, giving five measurements and about 4.9 million angle estimates (azimuth and elevation, every 25 ms). Each record contains the reported angles, the true angles computed from the known positions, the absolute angle errors, the true beacon position and the position computed from the receiver's angles. The dataset also contains the data behind Figs 6-9 of the related article (histograms of the angle errors and the search for the coefficients of the EEWA weighting function). See README.md for the set-up, receiver positions and column descriptions.
