KISMET project has been around for several decades and continues to get updates. The source code resides on GitHub and managed by dragon. I original got interested in capturing wireless packets and uploading to a database using an Android app called “Wigle”. It works well with very little effort, however, when I added KISMET software and loaded on raspberry pi, my capture rate went ten fold.
Installed KISMET on Raspberry PI 4. Picture shows RPi4 with battery, antenna and GPS attachments strap to the back of my roll bar in jeep.
