Windows 10蓝牙网关客户端ValueChanged问题

Question

我现在有一个蓝牙网关特征读取的问题。我试着用我自己的自定义配置文件运行代码

thermometerCharacteristic.ValueChanged += temperatureMeasurementChanged;

它会导致此异常

mscorlib.ni.dll中出现'System.ArgumentException‘类型的异常，但未在用户代码中处理

附加信息:值不在预期范围内。

我的函数参数如下所示

void temperatureMeasurementChanged(GattCharacteristic sender, GattValueChangedEventArgs eventArgs)

此代码类似于在MSDN上检索蓝牙LE数据的示例。你知道是什么导致了这种情况吗？非常感谢！

Check for thermometerCharacteristic.CharacteristicProperties == (GattCharacteristicProperties.Read | GattCharacteristicProperties.Notify)

订阅前：

     if (characteristic.CharacteristicProperties == (GattCharacteristicProperties.Read | GattCharacteristicProperties.Notify))
        {
            characteristic.ValueChanged += Characteristic_ValueChanged;

            GattCommunicationStatus status =
                       await characteristic.WriteClientCharacteristicConfigurationDescriptorAsync(
                       CHARACTERISTIC_NOTIFICATION_TYPE);
        }
