Web UI

The web UI at flashbay.dev provides the full flashbay experience without installing anything.

Dashboard

After logging in, the dashboard shows:

• Your active session (if any)
• Available boards with real-time status
• Credit balance and recent usage

Starting a session

Click Start Session on any available board. The system allocates a physical board and connects you within seconds.

Serial console

The embedded terminal (powered by xterm.js) connects to your board's UART over WebSocket. It behaves like a local serial monitor:

• Default baud rate: 115200
• Send input by typing — data is relayed in real-time
• Copy/paste supported

Flashing firmware

1. Click the Flash button in your session view
2. Select a .bin file from your machine
3. Progress streams live — you'll see esptool output in real-time
4. The serial console reconnects automatically after flashing

Power cycling

Click Reset to toggle the board's power. Useful for recovering from hung firmware.

Ending a session

Click End Session or close the browser tab. If you close the tab, the session enters a 30-second idle countdown — reconnect within 30 seconds to resume. After 30 seconds, the session ends and the board is released for other users.
