BLE Bridge

Web Bluetooth is only supported in Edge or Chrome on desktop/Android — not available in this browser.

Calibration

5:00

Stability: — mV0/30 samples

Setup — how to connect the sensor

Option A — Web Bluetooth (Edge / Chrome on desktop or Android)

1. Flash the nRF54L15 firmware and power the board. It will advertise as GasSensorDAQ.

2. Open this dashboard in Edge or Chrome. Scroll up to the BLE Bridge panel.

3. Enter your INGEST_SECRET once (stored in localStorage). Click Connect to GasSensorDAQ and select the device in the browser picker.

4. Data flows automatically — no Python, no terminal.

Option B — Python bridge (any OS, any browser on the same network)

1. pip install bleak requests

2. python ble_bridge.py --api https://<your-pages-url> --secret <INGEST_SECRET>

iPhone users: run the bridge on a Windows/Mac/Linux machine on the same network; the iPhone just opens the dashboard URL in Safari.
