无法使用c#连接蓝牙设备

Question

我正在使用 32 英尺库来开发蓝牙通信 WPF 应用程序，并且能够配对设备，但无法连接它，最终出现如下异常。

注意：我尝试连接手机和电脑等设备，但两者都给出了相同的错误，如下所述。

我在某个地方看到过这个问题，他们提到，这个问题可能是因为 32 英尺库与我电脑中的蓝牙设备不兼容。

但实际上，我已经在其他一些运行 Windows 7 操作系统 - 64 位的 PC 上对此进行了测试，并收到了相同的错误消息。

任何人都可以帮帮我。谢谢。

我的代码示例：

     availableDevices = sender.DiscoverDevicesInRange();
     UpdateStatus("Scan completed.");
