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,
    });
