Hi, did you check the dimension of csi? If you use 3x3 MIMO you'll need to select which transmission antenna you'd like to analyze. In the example code it is assumed that the packet was sent in a single stream and three receiving antennas.

See FAQ Question 2, Paragraph 2 under Nrx http://dhalperi.github.io/linux-80211n-csitool/faq.html

Hope this helps. //Martin
