iOSWebBLE SDK

Web Bluetooth SDK for iOS Safari. Scan, connect, and talk to BLE devices from any web app.

Packages

Quick Start

npm install @ios-web-bluetooth/core @ios-web-bluetooth/detect

import { initIOSWebBLE, isIOSSafari } from '@ios-web-bluetooth/detect';
import { WebBLE, WebBLEError } from '@ios-web-bluetooth/core';

// 1. On iOS Safari, detect the extension and prompt install if missing
if (isIOSSafari()) {
  await initIOSWebBLE({
    operatorName: 'MyApp',
    banner: { mode: 'sheet' },
    onReady: () => console.log('Extension ready'),
  });
}

// 2. Scan and connect (works on iOS Safari + Chrome + Edge)
const ble = new WebBLE();
const device = await ble.requestDevice({
  filters: [{ services: ['heart_rate'] }],
});

await device.connect();

// 3. Read a value
const value = await device.read('heart_rate', 'heart_rate_measurement');
console.log('Heart rate:', value.getUint8(1));

// 4. Subscribe to notifications
const unsub = device.subscribe('heart_rate', 'heart_rate_measurement', (v) => {
  console.log('Heart rate:', v.getUint8(1));
});

// 5. Clean up
unsub();
await device.disconnect();

Error Handling

All errors are WebBLEError instances with a typed code and a human-readable suggestion:

try {
  const device = await ble.requestDevice({
    filters: [{ services: ['heart_rate'] }],
  });
  await device.connect();
} catch (err) {
  if (err instanceof WebBLEError) {
    console.log(err.code);       // e.g. 'DEVICE_NOT_FOUND'
    console.log(err.suggestion); // 'No matching devices in range'
  }
}
