Flash over USB
Flash the board over a cable right from the browser — for a new board or when the device does not answer over Bluetooth. Any ESP32-S3 works: the firmware detects the memory type itself.
Connect the board with a USB cable (either socket on two-port boards) and press the button. If the board is not found, hold BOOT, press RESET and release BOOT.
Flashing over USB erases the whole flash: settings and password. The licence comes back by itself when the app connects with internet.
After flashing, connect the device over Bluetooth on the main screen and set a password.
