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功能。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。
我有带有 Visual Studio 2010 的 Windows SDK v7,使用 C/C++
谢谢。
使用我的32feet.NET库,如下所示。
编辑 3 月 3 日:我现在添加了代码来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(...)'。
看看是否能找到你想要的设备。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,我已将发现代码留在原处。)
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(并且处于可连接模式)。
