M5Stack Atom Lite — one-time setup over USB

1
Plug it in
Connect the Atom Lite to this computer with a USB-C cable. Use Chrome or Edge — Safari and Firefox can't do this. No drivers needed.
2
Flash it
Click the button below. Chrome will show a list of ports — pick the one that says usbserial (it'll usually say "M5stack" too). Ignore anything with "Bluetooth" or "debug" in the name. Then wait about a minute.
If the button doesn't do anything, you're not on Chrome or Edge.
3
Done
Once it finishes, unplug the cable, open the FlockWatch app, and pair with the detector over Bluetooth.
