Neither tcpdump nor wireshark can obtain data. #145

greetings, I am using RPI4, bcm434355c0. The whole process is finished, but tcpdump cannot receive data, and it cannot be captured using wireshark. At the same time, after the wireless network card turns on the monitoring mode, the ping command cannot be used to send packets to the wireless gateway. Because my experiment needs to monitor data packets of a specific address in a wireless environment, how can I solve it?

make sure that you are configure the nexutils right with changing the parameters at the utils/makeparams/makeparams. The channel, bandwith and mac are very important for a successful receive of CSI at nexmon

You should install nexmon to monitor data packets of a specific address in a wireless environment. Then you can't capture CSI. I am tring to find way to do both.
