Am I doing the wrong extraction? #45

Hi I'm going to analyze csi data and try to count people indoors. By the way, there is no problem when I extract the csi data, but when I do the plotting, there are many empty parts. At first, I thought there was a problem with the csi visualization tool, but after converting the pcap file into a csv file, I saw that there were a lot of empty parts. That's why I thought I was doing the extraction wrong. And my extraction speed is only 0hz to 10hz. I saw the answer about the extraction speed you explained on issue, but I am doing it on Windows OS.. Can you answer me about this as well? Thank you.

I will refer to the csi data I extracted. csi data.zip

I have another question. When extracting the csi with raspberry pie, do I need to have at least one electronic device connected to the router? Isn't Raspberry Pi itself acting as a receiver?
