Regarding BFi collection (URGENT)

[ayyp1]

Hi ,
I wanted to see the BFi and V matrices
so I connected my laptop(1) to my router working in 36 channel 5ghz where mu-mimo is enabled
I sent ping packets to my router to generate traffic and in my laptop(2) i enabled monitor mode and did tcpdump
but when i try to separate the BFA and Vmatrices using main.py I get error saying

packet = packets.next().frame_raw_value
StopIteration

am I doing anything wrong ?

do i need iperf or can I generate traffic using only ping ?
