Hello, I have implemented this patch on the Nexus 5 to extract CSI on Channel 44 of the 5GHz band. Currently, the beacon frame of the router can be seen which occurs at 100ms increments. I am inside with no known connections to the router. Will extracting CSI from this frame be too fast for the firmware?

Router: Sagemcom (4883c7d27897) I have attached two files, one showing the beaconing of the router and another with CSI output of the channel at a different time. It looks like somehow the filter I applied "2cd0010080000000ffffffffffff4883c7d27897" was rotated for the packets that did not output properly.

Any and all help would be appreciated. Thank you! data.tar.gz
