+# Bluetooth
+
+Configure the robot's WiFi and pair the BLE remote control without the phone app. Open from the landing page → **Bluetooth** tile.

+
+Scan, connect, fetch SN + AP MAC, configure WiFi (SSID, password, STA / AP mode, region). Adapter selector for switching between multiple HCI adapters (handy with USB dongles).
+
+Protocol versions:
+
+- **V1 / V2** — used by legacy firmware (Go2 `< 1.1.15`, G1 `< 1.5.1`). Standard Nordic UART or FFE0 service. See [bluetooth-v1-v2.md](bluetooth-v1-v2.md) for the full GATT layout and command schema.
+- **V3** — G1 `≥ 1.5.1` and Go2 `≥ 1.1.15`. Adds two new opcodes: `VERSION` (`0xF1`) and `GCM_KEY` (`0xF2`). The UI gates V3 probes on the scanned BLE name (`/^(G1|Go2)[_\W]/i`); older firmware silently drops the probe so it fails soft (a few-second timeout). See [bluetooth-v3.md](bluetooth-v3.md) for the magic-prefix handshake and key-exchange details.
+
+## Remote Control
+

+</p>
+
+Pair the Unitree BLE remote (`Unitree-*` advertising name) to read live joystick axes and button states, with an Hz counter showing the update rate.
+
+Once paired, a gamepad icon appears in the control view's setting bar — click it to relay the remote's input to the robot over the WebRTC `rt/wirelesscontroller` channel:

+
+## Running the BLE Server
+
+The dev `npm run start` script launches both Vite and the Python BLE backend together. To run them separately:
+
+```bash
+pip install -r server/requirements.txt
+npm run ble-server     # Python FastAPI BLE backend
+npm run dev            # Vite frontend (no BLE)
+```
+
+The frontend talks to the BLE server through Vite's `/ble-api/*` proxy, so CORS isn't a concern.
