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); 
}
