HarmonyOS 经典蓝牙的ssp连接和读取问题

clientSocket(code: BusinessError, number: number) { 
  console.log('bluetooth error code: ' + code + "->number=" + number); 
  if (code) { 
    console.error('sppListen error, code is ' + code); 
    return; 
  } 
  console.log('bluetooth serverSocket Number: ' + number); 
} 
let sppOption: socket.SppOptions = { 
  uuid: BluetoothClassicManager.SPP_UUID, 
  secure: true, 
  type: socket.SppType.SPP_RFCOMM 
}; 
socket.sppConnect(address, sppOption, this.clientSocket); 
//成功后设置监听 
socket.on('sppRead', this.clientNumber, (data: ArrayBuffer) => { 
  console.debug("->addRead data=" + data); 
});
