Web Bluetooth API

Web Bluetooth API — The Web Bluetooth API lets a web app request access to nearby Bluetooth Low Energy devices via navigator.bluetooth.requestDevice() and communicate with their GATT services.

How to use it

Requesting a device must happen inside a user gesture (e.g. a click handler), and you narrow the request with filters naming the GATT service(s) you intend to use:

async function connectHeartRateMonitor() {
  const device = await navigator.bluetooth.requestDevice({
    filters: [{ services: ['heart_rate'] }],
  });
  const server = await device.gatt.connect();
  const service = await server.getPrimaryService('heart_rate');
  const characteristic = await service.getCharacteristic('heart_rate_measurement');
  await characteristic.startNotifications();
  return characteristic;
}

How to detect it at runtime

Check for navigator.bluetooth before offering the feature, and give the reader a fallback path when it is absent:

if ('bluetooth' in navigator) {
  connectButton.hidden = false;
} else {
  connectButton.hidden = true;
  fallbackNotice.textContent = 'This browser cannot pair Bluetooth devices from the page.';
}

Practical checklist

• Requires a secure context — calling it from an insecure origin is not permitted.
• requestDevice() requires transient user activation (a click or tap handler); without it, the returned promise rejects with a SecurityError.
• If no device is available to return — for example the user does not select one — requestDevice() rejects with a NotFoundError.
• Support is not uniform across browsers or platforms; check the support table above before relying on the feature for a given target.
• Always pair the runtime check above with the support table, since a browser can expose navigator.bluetooth while still restricting behaviour in ways that only surface at request time.
