7. 外接设备控制功能

Important

1. 接口需要设备处于【外接设备模式】才能生效

2. 判断设备是否支持【外接设备模式】

public boolean isSupportAuxMode() {
    //获取RCSPController对象
    RCSPController controller = RCSPController.getInstance();
    //获取当前操作设备
    BluetoothDevice usingDevice = controller.getUsingDevice();
    if (null == usingDevice) return false;
    DeviceInfo deviceInfo = controller.getDeviceInfo(usingDevice);
    if (null == deviceInfo) return false; //设备未初始化
    return deviceInfo.isAuxEnable();
}

3. 判断设备是否处于【外接设备模式】

public boolean isDeviceInAuxMode() {
    //获取RCSPController对象
    RCSPController controller = RCSPController.getInstance();
    //获取当前操作设备
    BluetoothDevice usingDevice = controller.getUsingDevice();
    if (null == usingDevice) return false;
    DeviceInfo deviceInfo = controller.getDeviceInfo(usingDevice);
    if (null == deviceInfo) return false; //设备未初始化
    return deviceInfo.getCurFunction() == AttrAndFunCode.SYS_INFO_FUNCTION_AUX;
}

4. 查询当前设备模式

7.1. 获取外接设备播放状态

1. JL_BluetoothManager方式

function : AttrAndFunCode.SYS_INFO_FUNCTION_AUX – AUX功能

mask : 0x01 – 播放状态

命令构造

CommandBase getAuxPlayStatueCmd = CommandBuilder.buildGetAuxPlayStatueCmd();

代码示例参考 查询设备系统信息

2. RCSPController方式

//获取RCSPController对象
RCSPController controller = RCSPController.getInstance();
//添加蓝牙RCSP事件监听器
controller.addBTRcspEventCallback(new BTRcspEventCallback() {
    @Override
    public void onAuxStatusChange(BluetoothDevice device, boolean isPlay) {
        //此处回调外接设备播放状态
    }
});
//执行获取外接设备播放状态功能并等待结果回调
controller.getAuxStatusInfo(controller.getUsingDevice(), new OnRcspActionCallback<Boolean>() {
    @Override
    public void onSuccess(BluetoothDevice device, Boolean message) {
        //成功回调
        //结果将会在BTRcspEventCallback#onAuxStatusChange回调
    }

    @Override
    public void onError(BluetoothDevice device, BaseError error) {
        //失败回调
        //error - 错误信息
    }
});

7.2. 外接设备播放或暂停

1. JL_BluetoothManager方式

function : AttrAndFunCode.SYS_INFO_FUNCTION_AUX – AUX功能

type : AttrAndFunCode.FUNCTION_AUX_CMD_PAUSE_OR_PLAY – 播放或暂停

value : NULL

命令构造

CommandBase auxPlayOrPauseCmd = CommandBuilder.buildAuxPlayOrPauseCmd();

代码示例参考 设置功能

2. RCSPController方式

//获取RCSPController对象
RCSPController controller = RCSPController.getInstance();
//执行外接设备播放或暂停功能并等待结果回调
controller.auxPlayOrPause(controller.getUsingDevice(), new OnRcspActionCallback<Boolean>() {
    @Override
    public void onSuccess(BluetoothDevice device, Boolean message) {
        //成功回调
    }

    @Override
    public void onError(BluetoothDevice device, BaseError error) {
        //失败回调
        //error - 错误信息
    }
});
