c# - Windows 10 上的 BLE 服务器

Question

大家好，我正在尝试使用 Microsoft 的示例代码和在本网站 ( https://www.jenx.si/2019/08/09/bluetooth-gatt-server/ ) 中找到的教程在 Windows 10 上创建 BLE 服务器。问题是我可以使用桌面应用程序使服务器正常，但是当我尝试使用控制台示例代码时，我得到：

System.InvalidOperationException HResult=0x80131509 当任一应用程序没有控制台或控制台输入已被重定向时，无法读取密钥。试试 Console.Read。

错误。当我尝试继续按钮时，它会给我“找不到ExceptionDispatchInfo.cs”错误。任何人都可以帮助我解决这些错误。或者任何人都可以向我展示另一个示例，说明如何使用 C# 在控制台中的 Windows 10 上制作 BLE 服务器？

        await _logger.LogMessageAsync("The read operation will resume...\n");
    }

        await _logger.LogMessageAsync($"Characteristic with Guid: {myArgs.Characteristic.ToString()} changed: {myArgs.Value.ToString()}");
    }
