Get RSSI and CSI from .pcap file. #76

Hello @zeroby0 ,

Very excited to see your work, I too would like to extract RSS and CSI from .pcap file at the simultaneous, I am getting my data from AC86U router. I used MATLAB to read it and the same worked on https://github.com/nexmonster/nexmon_csi/tree/pi-5.4.51-plus/utils but no RSSI was extracted.

I want to extract the RSSI but I don't know exactly which byte corresponds to the RSSI, so I have no way to return the RSS. From the python code you shared I see that the RSS is extracted, can you share the byte that corresponds to the RSS from the pcap file?

Do the byte symbols extracted from the .pcap file need to be converted to get the RSSI?
