1 month ago Reduced the code to: BGT60LTR11AIP_stripped.py using device.get_config_defaults() Seem to get the same error message (with some more trace):

hence with "ENABLE_NEULOG = False",

Note: This BGT60LTR11AIP seems to work fine with "Radar Fusion GUI_3.5.4.202310241225" Note2: The same "Radar-Development-Kit/3.5.1.202310261055" seems to work fine with another device BGT60TR13C and another python code example: "Python Wrapper" from "Infineon/Tools/Radar-Development-Kit/3.5.1.202310261055/quickstart.html" (although needed to add "import numpy as np" at the beginning of this other example).
