Hi, I tried to save the data to csv When the status is Presence. I fixed X4M300_printout_presence_state.py source file.(add function read_frame from XEP_X4M200_X4M300_plot_record_playback_radar_raw_data.py) but, it is not working. i think xep.read_message_data_float() function can not work. How can i fix this? I uploadded the source code please check this. Thanks.
