第三方应用如何拿到蓝牙mac地址

import { connection } from '@kit.ConnectivityKit';
import { BusinessError } from '@kit.BasicServicesKit';

function onReceiveEvent(data: Array<string>) { // data为蓝牙设备地址集合
  console.info('bluetooth device find = '+ JSON.stringify(data));
}

try {
  connection.on('bluetoothDeviceFind', onReceiveEvent);
  connection.startBluetoothDiscovery();
} catch (err) {
  console.error('errCode: ' + (err as BusinessError).code + ', errMessage: ' + (err as BusinessError).message);
}
