Bridge setup
A bridge is a coin-sized board that lives on the calculator's link port and does the thinking itself — its own WiFi, its own camera, no computer. You use this page once, over Bluetooth, to hand it a network and a key.
Pair a bridge
Power the bridge on and hold its button until the light pulses, then pair it here. Bluetooth is only used for setup — after this it runs on its own.
WiFi
The network the bridge joins to reach your AI provider. It cannot see 5 GHz-only networks — the ESP32 is 2.4 GHz.
AI provider
The bridge calls the provider directly. The key is written to its flash and never comes back out.
Bridge
What it calls itself, and what its camera is for.
Settings live in RAM until you save. Anything left blank is left as it was.
Bluetooth here is plain Nordic UART. If your firmware does not require bonding, anything in radio range can read what you type on this page — so require a passkey before shipping a bridge with a real key on it.
