设备绑定

设备绑定方式提供二维码、蓝牙配网绑定、4G绑定、AP配网绑定方式

总体介绍参考设备绑定开发指南。

设备绑定流程

App调用prepareAddDevice方法后，当监听到RTCXFluDeviceAddStatus_Prepared状态时可获取bindToken (有效时长30分钟)。
将bindToken传递给设备(二维码、蓝牙等)，设备保证网络连通情况下，通过DeviceSDK进行设备绑定
在RTCXFluDeviceAddStatus_Prepared状态下，App只需要调用startAddDevice方法实时监听绑定状态回调即可（超时自行控制，最大超时依赖bindToken的有效时长）。

class RTCXFluAddDeviceApi {
  /// 添加设备
  /// 准备添加设备，成功才可以进行下一步
  void prepareAddDevice(RTCXFluDeviceAddType deviceAddType);

  /// 添加事件回调
  void onDeviceAddListener();

  /// 开始添加设备，成功才可以进行下一步
  void startAddDevice(RTCXFluDeviceAddReq req);

  /// 开始添加设备, 有线方式
  void startAddWRDevice(RTCXFluDeviceAddWRReq req);

  /// 开始添加设备, 二维码方式
  void startAddQRDevice(RTCXFluDeviceAddQRReq req);

  /// 开始添加设备, 4G方式
  void startAdd4GDevice(RTCXFluDeviceAdd4GReq req);

  /// 开始添加设备, 蓝牙绑定方式
  void startAddBTDevice(RTCXFluDeviceAddBTReq req);

  /// 开始添加设备, AP绑定方式
  void startAddAPDevice(RTCXFluDeviceAddAPReq req);

  /// 停止添加设备
  void stopAddDevice();

  /// 获取二维码内容
  @async
  List<String> getQRCodeData(RTCXFluDeviceAddQRReq req);

  /// 获取蓝牙授权权限
  @async
  RTCXFluBTAuthorizeStatus getBluetoothAuthorizeStatus();

  /// 开始扫描蓝牙设备
  @async
  List<RTCXFluBTLinkDevInfoRsp> startScanBTDevices(RTCXFluBTLinkScanReq req);

  /// 停止扫描蓝牙设备
  void stopScanBTDevices();

  /// 连接蓝牙设备
  @async
  RTCXFluBTLinkResult connectLinkBTDevice(RTCXFluBTLinkNetworkingReq req);

  /// AP开始连接
  @async
  RTCXFluAPLinkResult startAPLinkConnect(RTCXFluAPLinkConnectReq req);

  /// AP发送配网信息
  @async
  RTCXFluAPLinkResult sendAPLinkNetworking(RTCXFluAPLinkNetworkingReq req);
}

注意

需要prepareAddDevice:方法之前注册监听

二维码绑定

调用示例如下：

注册监听，并准备绑定

  final addDeviceApi = RTCXFluAddDeviceController();
  @override
  void initState() {
    super.initState();
    addDeviceApi.onDeviceAddListener();
    addDeviceApi.onDeviceAdd.listen((data) {
      if (data.status ==
          RTCXFluDeviceAddStatus.RTCXFluDeviceAddStatus_Success) {
        Fluttertoast.showToast(msg: "绑定成功");
      } else if (data.status ==
          RTCXFluDeviceAddStatus.RTCXFluDeviceAddStatus_Prepared) {
        Fluttertoast.showToast(msg: "已准备好添加设备");
        debugPrint("error : ${data.error.code} -- ${data.error.message}");
      } else {
        Fluttertoast.showToast(
          msg: "绑定结果：${data.status.name} + error:$data.error",
        );
      }
    });
    
    // 准备二维码绑定
    addDeviceApi.prepareAddDevice(RTCXFluDeviceAddType.RTCXFluDeviceAddType_QR);
  }

通过二维码绑定方式，生成带有 WiFi 名和密码的二维码内容

  // 需要传递productKey、deviceName、ssid、wifiPwd
  void getQRCodeData() async {
    try {
      final String productKey = "";
      final String deviceName = "";

      RTCXFluDeviceAddQRReq req = RTCXFluDeviceAddQRReq(productKey: productKey, deviceName: deviceName, ssid: "", wifiPwd: "");
      addDeviceApi.getQRCodeData(req).then((List<String>? qrCodeStrings) {
        if (qrCodeStrings!.isNotEmpty) {
          setState(() {
            qrcodeString = qrCodeStrings.first;
          });
          Fluttertoast.showToast(msg: 'qrcodeString:${qrcodeString}');
        }
      });
    } catch (e) {
      Fluttertoast.showToast(msg: '解析二维码失败: $e');
    }
  }

开始二维码绑定

  void _startQRAddDevice() {
    // 开始添加设备
    addDeviceApi.startAddQRDevice(
      RTCXFluDeviceAddQRReq(
        productKey: "productKey",
        deviceName: "deviceName",
      ),
    );
  }

结束绑定

  // 在diapose中调用stopAddDevice与destroy方法
  @override
  void dispose() {
    super.dispose();
    addDeviceApi.stopAddDevice();
    addDeviceApi.destroy();
  }

4G绑定

设备已配有4G网，通过4G绑定方式进行绑定。调用示例如下：

注册监听，并准备绑定

  final addDeviceApi = RTCXFluAddDeviceController();
  @override
  void initState() {
    super.initState();
    addDeviceApi.onDeviceAddListener();
    addDeviceApi.onDeviceAdd.listen((data) {
      if (data.status ==
          RTCXFluDeviceAddStatus.RTCXFluDeviceAddStatus_Success) {
        Fluttertoast.showToast(msg: "绑定成功");
      } else if (data.status ==
          RTCXFluDeviceAddStatus.RTCXFluDeviceAddStatus_Prepared) {
        Fluttertoast.showToast(msg: "已准备好添加设备");
        debugPrint("error : ${data.error.code} -- ${data.error.message}");
      } else {
        Fluttertoast.showToast(
          msg: "绑定结果：${data.status.name} + error:$data.error",
        );
      }
    });
    
    // 准备4G绑定
    addDeviceApi.prepareAddDevice(RTCXFluDeviceAddType.RTCXFluDeviceAddType_4G);
    _addDeviceBy4G();
  }

开始4G绑定

  // 调用startAdd4GDevice，等待绑定结果状态监听回调
  void _addDeviceBy4G() {
    RTCXFluDeviceAdd4GReq req = RTCXFluDeviceAdd4GReq(productKey: '填写设备的productKey', deviceName: '填写设备的deviceName');
    //请不要更改req的deviceAddType类型。
    addDeviceApi.startAdd4GDevice(req);
  }

结束绑定

  // 在diapose中调用stopAddDevice与destroy方法
  @override
  void dispose() {
    super.dispose();
    addDeviceApi.stopAddDevice();
    addDeviceApi.destroy();
  }

蓝牙配网绑定

通过蓝牙配网方式，将WI-FI及WI-FI密码发给设备，进行绑定设备方式。蓝牙绑定前需要配置权限，详细配置权限请见配置权限

调用示例如下：

注册监听，并准备绑定

  var addDeviceApi = RTCXFluAddDeviceController();
  
  @override
  void initState() {
    super.initState();
    addDeviceApi.onDeviceAddListener();
    addDeviceApi.onDeviceAdd.listen((data) {
      print("绑定结果：data: ${data.toString()}");
      if (data.status ==
          RTCXFluDeviceAddStatus.RTCXFluDeviceAddStatus_Success) {
        Fluttertoast.showToast(msg: "绑定成功");
      } else if (data.status ==
          RTCXFluDeviceAddStatus.RTCXFluDeviceAddStatus_Prepared) {
        Fluttertoast.showToast(msg: "已准备好添加设备");
        debugPrint("error : ${data.error.code} -- ${data.error.message}");
      } else {
        Fluttertoast.showToast(
          msg: "绑定结果：${data.status.name} + error:$data.error",
        );
      }
    });
    _prepare();
  }

  void _prepare() {
    addDeviceApi.prepareAddDevice(RTCXFluDeviceAddType.RTCXFluDeviceAddType_BT);
  }

获取蓝牙权限

  void _getBluetoothAuthorizeStatus() {
    addDeviceApi.getBluetoothAuthorizeStatus().then((RTCXFluBTAuthorizeStatus status) {
      if (RTCXFluBTAuthorizeStatus.RTCXFluBTAuthorizeStatus_PoweredOn == status) {
        _startScanDevices();
      } else {
        Fluttertoast.showToast(msg: '获取蓝牙权限status: $status');
      }
    }).catchError((error) {
      Fluttertoast.showToast(msg: '获取蓝牙权限失败: $error');
    });
  }

获取蓝牙权限后，开始扫描设备

  void _startScanDevices() {
    RTCXFluBTLinkScanReq req = RTCXFluBTLinkScanReq(namePrefixs: [
        "XSDEV_","XS_"
    ]);
    addDeviceApi.startScanBTDevices(req).then((result){
      if (result.isNotEmpty) {
         // 扫描出的蓝牙设备
        List<RTCXFluBTLinkDevInfoRsp> deviceList = result;
      } else {
        Fluttertoast.showToast(msg: '未搜索到设备');
      }
    }).catchError((error) {
      Fluttertoast.showToast(msg: '扫描设备失败: $error');
      _stopScanBTDevices();
    });
  }
  
  // 停止扫描设备
  void _stopScanBTDevices() {
    addDeviceApi.stopScanBTDevices();
  }

连接蓝牙设备

连接选择要绑定的设备，将WI-FI的名称及WI-FI密码发给设备。并进行绑定。

  // 选择要绑定的设备后，连接蓝牙设备，
  // 连接蓝牙设备，需要先调用获取到二维码字符串后，调用connectLinkBTDevice
  void _connectLinkBTDevice(RTCXFluBTLinkDevInfoRsp info) {
    // 这里productKey，deviceName没有就 传空字符串。
    RTCXFluDeviceAddBTReq btReq = RTCXFluDeviceAddBTReq(productKey: '', deviceName: '');
    // 调用startAddBTDevice
    addDeviceApi.startAddBTDevice(btReq);

    // 获取WI-FI、WI-FI密码content，发送给蓝牙设备
    RTCXFluDeviceAddQRReq req = RTCXFluDeviceAddQRReq(productKey: "", deviceName: "", ssid: "WI-FI的名称", wifiPwd: "WI-FI的密码");
    addDeviceApi.getQRCodeData(req).then((List<String>? qrCodeStrings) {
      if (qrCodeStrings!.isNotEmpty) {
        String qrcodeString = qrCodeStrings.first;
        RTCXFluBTLinkNetworkingReq req = RTCXFluBTLinkNetworkingReq(sn: info.sn, content: qrcodeString);
        addDeviceApi.connectLinkBTDevice(req).then((RTCXFluBTLinkResult result){
          if (true == result.success) {
            // 连接成功，等待addDeviceApi.onDeviceAdd.listen绑定结果
            // 可以设置定时器如2分钟，超时则认为绑定失败。addDeviceApi.onDeviceAdd.listen返回后关闭定时器。
          } else {
            Fluttertoast.showToast(msg: '连接设备失败');
          }
        }).catchError((error) {
          Fluttertoast.showToast(msg: '连接设备失败: $error');
        });
      } else {
        Fluttertoast.showToast(msg: '获取content失败');
      }
    }).catchError((error) {
      Fluttertoast.showToast(msg: '获取content失败: $error');
    });
  }

结束绑定

  // 在diapose中调用stopAddDevice与destroy方法
  @override
  void dispose() {
    super.dispose();
    addDeviceApi.stopAddDevice();
    addDeviceApi.destroy();
  }

AP配网绑定

设备AP配网时，待设备重置后，等待设备待连接状态，连接设备的热点，通过App传输Wi-Fi的SSID和密码，使设备加入目标网络。

调用示例如下：

注册监听，并准备绑定

  var addDeviceApi = RTCXFluAddDeviceController();
  @override
  void initState() {
    super.initState();
    addDeviceApi.onDeviceAddListener();
    addDeviceApi.onDeviceAdd.listen((data) {
      print("绑定结果：data: ${data.toString()}");
      if (data.status ==
          RTCXFluDeviceAddStatus.RTCXFluDeviceAddStatus_Success) {
        Fluttertoast.showToast(msg: "绑定成功");
      } else if (data.status ==
          RTCXFluDeviceAddStatus.RTCXFluDeviceAddStatus_Prepared) {
        Fluttertoast.showToast(msg: "已准备好添加设备");
        debugPrint("error : ${data.error.code} -- ${data.error.message}");
      } else {
        Fluttertoast.showToast(
          msg: "绑定结果：${data.status.name} + error:$data.error",
        );
      }
    });
      _prepare();
  }

  void _prepare() {
    // 先添加代理 在调用
    addDeviceApi.prepareAddDevice(RTCXFluDeviceAddType.RTCXFluDeviceAddType_AP);
  }

AP连接与发送配网信息

手机连接设备的热点后，调用startAPLinkConnect接口

  // 调用AP连接
  Future<void> _startAPLinkConnect() async {
    try {
      RTCXFluAPLinkConnectReq req = RTCXFluAPLinkConnectReq();
      RTCXFluAPLinkResult result = await addDeviceApi.startAPLinkConnect(req);
      if (true == result.success) {
        // 连接成功
      } else {
        Fluttertoast.showToast(msg: 'AP连接失败: $e');
      }
    } catch(e) {
      Fluttertoast.showToast(msg: 'AP连接失败: $e');
    }
  }
  
  // 发送WI-FI、WI-FI密码给设备
  Future<void> _sendNetworking() async {
    try {
      RTCXFluAPLinkNetworkingReq req = RTCXFluAPLinkNetworkingReq(ssid: 'wifi名', pwd: 'wifi密码');
      RTCXFluAPLinkResult result = await addDeviceApi.sendAPLinkNetworking(req);
      if (true == result.success) {
        // 连接成功
      } else {
        Fluttertoast.showToast(msg: 'AP配网信息失败');
      }
    } catch(e) {
      Fluttertoast.showToast(msg: 'AP配网信息失败: $e');
    }

注意

发送WiFi名称、WiFi密码后，设备连接上WIFI后，设备会主动断开热点。设备主动断开热点后，APP会断开网络后重新连接其他网络。

绑定设备

APP会断开网络后重新连接其他网络后进行绑定

  Future<void> addAPDevice() async {
    try {
      RTCXFluDeviceAddAPReq req = RTCXFluDeviceAddAPReq(productKey: '设备的productKey', deviceName: '设备的deviceName');
      await addDeviceApi.startAddAPDevice(req);
    } catch(e) {
      Fluttertoast.showToast(msg: 'AP配网信息失败: $e');
    }
  }

结束绑定

  // 在diapose中调用stopAddDevice与destroy方法
  @override
  void dispose() {
    super.dispose();
    addDeviceApi.stopAddDevice();
    addDeviceApi.destroy();
  }

        Fluttertoast.showToast(msg: '解绑成功');
      } else {
        Fluttertoast.showToast(msg: '解绑失败');
      }
    } catch (e) {
      Fluttertoast.showToast(msg: '解绑失败: $e');
    }

      setState(() {
        dataList = result.data;
        // 判断是否还有更多
        bool hasMore = (result.data?.length ?? 0) < (result.total ?? 0);
      });
    } catch (e) {
      Fluttertoast.showToast(msg: "获取设备列表失败: $e");
    }

        // 判断是否还有更多
        bool hasMore = (result.data?.length ?? 0) < (result.total ?? 0);
      });
    } catch (e) {
      Fluttertoast.showToast(msg: "获取子设备列表失败: $e");
    }

设备缩略图

获取设备缩略图

 void getDeviceThumb(RTCXFluDeviceInfoModel info) {
   RTCXFluGetDeviceThumbnailReq req = RTCXFluGetDeviceThumbnailReq(
       productKey: '${info.productKey}',
       deviceName: '${info.deviceName}',

 }

通过物模型服务获取设备缩略图

// 导入物模型头文件
import 'package:airtc_engine/src/thing/rtcx_thing.dart';
import 'package:airtc_engine/src/thing/rtcx_thing_controller.dart';

  late RTCXFluThingController _thingApi;
  
  @override
  void initState() {
    super.initState();
    // 物模型
    RTCXFluThingReq req = RTCXFluThingReq(
      productKey: widget.productKey,
      deviceName: widget.deviceName,
      iotId: widget.iotId,
      deviceType: widget.deviceType,
    );
    _thingApi = RTCXFluThingController();
    _thingApi.buildThing(req);
    _thingApi.registerThingObserver();
    _thingApi.onStatusChange.listen((data) {
      print("onStatusChange:"+data.toString());
    });
    _thingApi.onDeviceTransferMessage.listen((RTCXFluThingObserver observer) {
      print("onDeviceTransferMessage:"+observer.toString());
    });
  }
  
  Future<void> getDeviceThumb() async {
    try {
      final result = await _thingApi.invokeService(
        RTCXFluThingCommand(
          command: "GetDevPicture",
          params: {
            "definition": 1,
            "picType": "jpg",
          },
        ),
      );
      if(result.success && result.dataObject != null) {
        Map<String, dynamic> dataObjectMap = jsonDecode(result.dataObject!);
        // 获取的设备缩略图
        String? picUrl = dataObjectMap["downloadUrl"];
      }
      Fluttertoast.showToast(msg: "获取缩略图${result == true ? "成功" : "失败"}, ${result.dataObject}");
    } catch(e) {
      Fluttertoast.showToast(msg: "获取缩略图失败:${e.toString()}");
    }
  }
  
  // 不需要的时候需要做destroy释放操作
  @override
  void dispose() {
    super.dispose();
    _thingApi.destroy();
  }

低功耗设备唤醒

class RTCXFluDeviceApi {
  /// 休眠设备唤醒，可以通过定时器循环调用唤醒设备，唤醒成功后关闭定时器，并且进行播放
  @async
  RTCXFluDeviceResult wakeupDevice(String iotId);
}

低功耗设备唤醒调用示例

  Future<void> _wakeupDevice(String iotId) async {
    try {
      final result = await deviceApi.wakeupDevice(iotId);
      if (result.success == true) {
        Fluttertoast.showToast(msg: '调用成功');
      } else {
        Fluttertoast.showToast(msg: '调用失败');
      }
    } catch (e) {
      Fluttertoast.showToast(msg: '调用失败: $e');
    }
  }

注意

调用该接口只代表触发了低功耗设备唤醒，其返回成功结果并不代表设备已经唤醒上线（因为唤醒需要一定的时间）
针对低功耗设备的播放，APP需要按如下逻辑实现：
1. 调用唤醒接口触发设备唤醒
2. 监听设备上线，监听方式有两种：a. 定时器轮询物模型的RTCXFluThingResult getStatus()接口 b. 或者代理协议监听物对象的void onStatusChange(RTCXFluThingObserver value)协议方法
3. 设备上线后再调用播放器进行播放
为了防止低功耗设备在播放过程中休眠（比如从播放页进入设置页去设置一些参数，此时如果设备休眠，是无法成功设置参数的），App需要在播放界面使用定时器调用物模型，向设备发送物服务WakeupHeartbeat心跳（间隔可控制10秒一次），保持低功耗设备不休眠，播放界面销毁时，停止定时器
