collect CSI from pi4 with AP in pi3b+ and pc send pings

[yael1994]

Hi everyone, I try to collect CSI data with pi4 nexmon_csi BCM43455c0, kernel 5.4.83-v7l. The pi4 in monitor mode and I try to get CSI from packets between pi3b+ with AP and pc that send pings. the AP is on channel 36. I got 0 packets.

The commands I used: mcp -c 36/80 -C 1 -N 1 (i try without and with mac address of the pc ) ifconfig wlan0 up nexutil -Iwlan0 -s500 -b -l34 -v.. iw dev wlan0 interface add mon0 type monitor ip link set mon0 up tcpdump -i wlan0 dst port 5500 -vv -w output.pcap -c 1000

I got packets only when I do: mcp -c 157/80 -C 1 -N 1

When I do write the command at pi4 "iwlist wlan0 channel" I got that the pi4 on channel 36 too.
