# mqtt 说明

- 当前版本8.0.0, 更新日期2020/10/25
- 在mqtt/lib/src/utility/mqtt_client_payload_builder.dart添加

```dart
// added by jackning, 2019/12/03
  void addProtobuf(Uint8List val) {
    _payload.addAll(val);
  }
```

- 修改src/messages/connect/mqtt_client_mqtt_connect_payload.dart注释掉函数 set clientIdentifier限制clientId长度的代码

## TODO

- 搞定继承MqttClientPayloadBuilder之后，将mqtt包改为package依赖
