C# 统一可调装置

我正在尝试在Unity3D中创建一个游戏，该游戏连接到支持心率服务的蓝牙低能设备，并收集HR数据。我已经创建了一个WPF库，它已经在控制台应用程序上进行了测试，可以连接到一个BLE设备并读取工作正常的数据。然而，我不知道如何在统一中使用它

我将库转移到Unity，并不得不为编辑器禁用它，因为代码使用编辑器不支持的Windows命名空间。我现在的问题是如何在Unity中调试代码，以便在运行游戏时检查库代码是否正常工作。我尝试在#if NETFX_CORE、#if ENABLE_WINMD_SUPPORT、#if WINDOWS_UWP和其他许多文件中包装调用库名称空间和库中函数的代码，但从未获得我编写的任何调试日志

有什么可能的解决办法吗？ 任何帮助都将不胜感激，谢谢

这是蓝牙LE连接库的代码：

在Unity中使用UWP/.Net仅核心功能进行调试对我来说似乎是不可行的工作流，因为编辑编译运行周期很长。Unity编辑器使用.Net Framework运行，因此无法直接访问.Net核心功能。对于非Unity项目，可以通过Windows提供的包装器从.Net Framework访问UWP-API。但这对团结不起作用，因为有些团结的具体情况1

<>但是，有可能在C++ WRRT-DLL中封装UWP调用，并将DLL复制到Unity。这样，UWP-API也可以在Unity编辑器中使用（例如，按下播放按钮时）。我的用例也需要BLE，我上传了我的包装器。如果你愿意，你可以自由地把它作为起点

最后一件事：随着.Net版本5也宣布推出Unity，我想这应该已经过时了，因为据说版本5合并了.Net Framework和.Net Core

[1] 这个答案的许多信息来自于。

如果不使用代码，就很难说出代码。不过，你可以试试这个，节省你的时间：谢谢你的建议，我尝试了你提供的这个链接，但是，所有的代码都给了我编译错误，没有运行。DLL，这样你就可以打开Unity项目：（将DLL放入资产文件夹）。谢谢，有关于这个的文档吗？我已经将我的设备连接到unity项目，现在我不知道如何检索特征值（服务是heart 0X180D，特征是心率测量）。谢谢大家!@MikePetrichenko我已经完成了所有工作，但是当我尝试读取支持的心率测量值时，我看到UUID显示在调试日志中，我不断地得到结果值“331808”，心率值没有返回。我应该做些什么来获得价值？非常感谢。这是一个伟大的回购，做得好。只有两个问题：当你说“要尝试它，你可以将文件复制到可调试文件夹”时，你引用的是另一个repo吗？我在你的可调试文件夹中没有看到unity场景，我在你的存储库中有测试它所需的一切吗？问题2:debugable/BleWinrtDll.dll是否已经有我可以使用的预编译文件，或者您是否建议按照您的说明自己编译一个？嗨，乔，谢谢！问题1：不，这是相同的回购协议。DebugBle是一个控制台应用程序，您可以在其中试用它。一切都包括在内。但是你也应该能够在Unity中使用完全相同的C代码。我只是还没有在回购协议中添加统一场景。问题2：是的，debugable/BleWinrtDll.dll是一个预编译版本，因此您可以直接启动debugable。你也应该能够统一使用它。如果dll失败或出于安全原因，您也可以编译自己的dll（以确保我或github黑客没有篡改dll来监视您；）。
