Windows上QtBluetooth的替代品? [英] Alternatives to QtBluetooth on Windows?

问题描述

我有两台PC，它们没有通过电缆连接并且不在网络中，需要相互通信.我正在做两个Qt应用程序，想通过蓝牙进行通信.但是，我发现Qt不支持Windows的蓝牙( Qt是否支持Windows蓝牙API?). (产生qt.bluetooth: Dummy backend running. Qt Bluetooth module is non-functional.)

I have two PCs, not connected with a cable and not in a network that need to communicate with each other. I'm doing two Qt apps and wanted to make the communication via Bluetooth. However, I found out that Qt does not support Bluetooth for Windows (Does Qt support the windows bluetooth API?). (It produces qt.bluetooth: Dummy backend running. Qt Bluetooth module is non-functional.)

那么，我还必须通过蓝牙其他哪些方式来建立这种连接? 或者如何使QtBluetooth工作?我愿意接受新的建议.

So what other alternatives do I have to bluetooth to establish this connection? Or how can I make QtBluetooth work? I am open for new suggestions.

要传输的数据是QByteArray.

我正在运行Windows 10 Pro和Qt 5.11.1.

I am running Windows 10 Pro and Qt 5.11.1.

根据 Qt是否支持Windows蓝牙API? ，QtBluetooth确实可以在Windows上运行.我有两个Windows设备，它们具有完全相同的Windows和Qt版本.在其中一个上，蓝牙聊天示例可以完美地在另一个仍然没有，并且我收到错误消息Qt Bluetooth module is non-functional.有人可以告诉我何时以及为什么出现此错误吗?

According to the new answer on Does Qt support the windows bluetooth API?, QtBluetooth can indeed work on Windows. I have two windows devices with exactly the same windows and Qt version. On one of them the Bluetooth chat example works perfectly, on the other one it still doesn't and I get the error message that Qt Bluetooth module is non-functional. Can someone tell me when and why this error appears?

我也看到了该线程，但是它对我没有帮助，因为它是特定于Linux的.

I have also seen this thread but it doesn't help me, because it's linux-specific.

推荐答案

This thread on the QtForum delivered the answer. It works when you switch to the MSVC compiler instead of the standard MinGW!

这是您的操作方式:

在安装Microsoft Visual Studio并在Qt中安装了MSVC软件包之后(请参见前面提到的线程)，您需要通过转到工具">选项">工具包"来设置c ++的编译器.在此处选择MSVC编译器，然后在编译器:C ++:"中选择Microsoft Visual C ++编译器.

After installing Microsoft Visual Studio and having the MSVC package in Qt (see mentioned thread), you need to set the compiler for c++ by going to Tools>Options>Kits. There you choose the MSVC compiler and in "Compiler: C++:" you choose Microsoft Visual C++ Compiler.

我希望这对其他人有帮助.
