ESPrtk's calibration quality is very high.
The result was astonishing, with 99.99% eliminated noise. The algorithm works very well, even when only 1/4 surface point data exist in input data. Distortion and eccentricity due to hard-iron and soft-iron are completely removed.
The algorithm was developed exclusively by the ESPrtk development team and is already available on ESPrtk 3.9.8, so please update your ESP32 firmware.
