In your algorithm you use 2.48GHz frequency, however Minew also publish two additional frequencies - 2.402 GHz, 2.426 GHz. I've plugged them into your algorithm with improving wavelength calculations(lambda = c / f, where c is speed of light and f is frequency) and got three different angles. Results are presented in histogram below. As can be seen in the plot different frequencies result in very different angles. Do you know what's causing this? Thanks

Hello! I remember that when the frequency changes, the wavelength will also change, which will affect the guidance factor in the music algorithm, so it will produce different estimation angles. I'm not sure if that's the reason? thank you

Hello @HaZdula, can't give you a hint on this issue. We've just selected the frequency that resulted in correct angle and filtered other frequencies out. There should be possible to combine information from all 3 frequencies, but this was not in our integration scope.
