This is a report on a successful build for Raspberry Pi 4 / Raspberry Pi OS . I attempted a build of the other "raspbian" repo that would not build.

The RTL8812BU device is being used for network security scanning.

Testing

sudo iw dev INTERFACE  scan > scan-2023-12-14.txt

enabling MONITOR on the interface seems to crash the kernel. I'm looking into acquiring debug logs .

sudo iw phy phy1 interface add mon0 type monitor
