我在 Linux 中使用了 Bluez 蓝牙堆栈，它带有一个方便的实用程序“hcitool”。希望在 Windows 中构建具有相同或等效功能的类似东西。具体来说，'hcitool name < mac="">'，显示指定设备是否在范围内。 任何指导将不胜感激。

我有 Windows SDK v7 和 Visual Studio 2010，使用 C/C++

谢谢。

最佳答案

使用我的 32feet.NET类似下面的库。

编辑 3 月 3 日:我现在添加了代码以直接按地址查找设备，而不是使用设备发现；所以这是一个简单的“new BluetoothDeviceInfo(...)”。

看看是否找到了您想要的设备。这要求远程设备仅处于“可连接”模式，而前者要求它处于“可发现”模式。 (顺便说一句，我已经将发现代码留在原地。)

编辑 3 月 8 日:现在进行连接(使用 SDP API)以检查设备是否在范围内(并处于可连接模式)。
