hello Mr. Hernandez, Thank you for the helpful material, i just have some issues. first issue, sometimes when i run the code, i got a blank excel sheet. second issue, could you please provide me the documentation of the excel sheet, because some parameters and values are unknown and undefined. third issue, i tried python code for plotting the CSI data, but unfortunately its not working. thank you, Wael.

  2. Can you please specify which parameters are not clear? If you are asking for the CSI data format, it seems to be following [imag real imag real imag real...]: https://github.com/StevenMHernandez/ESP32-CSI-Tool/blob/cce5b1a055fae5b01b30d1d39c5cfa1e0c656696/python_utils/parse_csi.py#L14
