调用方法：
bluetooth = new BluetoothLECode(_serviceGuid, _writeCharacteristicGuid, _notifyCharacteristicGuid);
bluetooth.ValueChanged += Bluetooth_ValueChanged;
其中三个参数：
private string _serviceGuid = "0000ffe0-0000-1000-8000-00805f9b34fb";
private string _writeCharacteristicGuid = "0000ffe1-0000-1000-8000-00805f9b34fb";
private string _notifyCharacteristicGuid = "0000ffe1-0000-1000-8000-00805f9b34fb";
可以使用BLE蓝牙工具查看：
_serviceGuid：服务UUID
_writeCharacteristicGuid: 特征值UUID
_notifyCharacteristicGuid: 通知UUID
