Once the Feather starts up, you'll see a screen color test and then it will attempt to connect to your WiFi router using the credentials you provided in config.h. If it doesn't connect, go back to that step and verify your credentials are correct.
Once connected, you should stand still while it achieves gain lock and then it'll tell you when it is Ready!
The ESPectre then starts sending packets and measuring the CSI values. While these are stable, the screen will say Idle.
MOTION
Once you move around a bit or enter the detection area, the CSI variance will be enough to trigger the MOTION alert.
You can, of course, use this in all sorts of interesting ways, that part is up to you. Want to blast a horn? Drop a water balloon? Turn on the stereo? Have fun with it!
