Contribution description
9.2.1 Image Calibration for Specific Frequency Bands
Image calibration is done through the command CalibrateImage(...) for a given range of frequencies defined by the
parameters freq1 and freq2. Once performed, the calibration is valid for all frequencies between the two extremes used as
parameters.
If you do the calibration and do not call:
sx126x_set_standby(dev, SX126X_STANDBY_CFG_XOSC);the TCXO stays off.It is required.
