Package Exports

react-native-peripheral2
react-native-peripheral2/lib/commonjs/index.js
react-native-peripheral2/lib/module/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-native-peripheral2) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Request permission

Should check permission before create peripheral instance

import { PermissionsAndroid } from 'react-native';

await PermissionsAndroid.request(
  PermissionsAndroid.PERMISSIONS.BLUETOOTH_CONNECT,
  options,
);
await PermissionsAndroid.request(
  PermissionsAndroid.PERMISSIONS.BLUETOOTH_ADVERTISE,
  options,
);

Usage

import Peripheral, { Permission, Property } from 'react-native-multi-ble-peripheral';
import { Buffer } from 'buffer';

Peripheral.setDeviceName('MyDevice');

const peripheral = new Peripheral();

// We need wait peripheral manager ready before any operation.
peripheral.on('ready', async () => {
  await peripheral.addService('uuid', true);
  await peripheral.addCharacteristic(
    'uuid',
    'uuid2',
    Property.READ | Property.WRITE,
    Permission.READABLE | Permission.WRITEABLE
  );
  await peripheral.updateValue('uuid', 'uuid2', Buffer.from('Hello World!'));
  await peripheral.startAdvertising();
  // or advertising with service
  await peripheral.startAdvertising({uuid: null});
  // or advertising with service data
  await peripheral.startAdvertising({uuid: 'data'});
});

peripheral.on(
  'write',
  async ({
    requestId,
    device,
    deviceName,
    characteristic,
    service,
    value,
  }) => {
    const data = base64.decode(value);
    console.log('Peripheral write', {
      requestId,
      device,
      deviceName,
      characteristic,
      service,
      data,
    });
  })
