Wireless API for Linux in C or Java
提问by Dimitri
my team and I are working in a project based on the drone Parrot API. We are trying to find an api to write a small program which can scan the wireless network and selects the drone ESSID. Our main language is C but Java is also appreciated.
我和我的团队正在一个基于无人机 Parrot API 的项目中工作。我们正在寻找一个api来编写一个小程序，可以扫描无线网络并选择无人机ESSID。我们的主要语言是 C，但 Java 也很受欢迎。
I tried to look if exist any API for the iwlist/iwconfig command but i did not find anything. Can someone help me plz? Any example (code sample) will also be appreciated.
我试图查看 iwlist/iwconfig 命令是否存在任何 API，但我没有找到任何东西。有人可以帮我吗？任何示例（代码示例）也将不胜感激。

With newer kernels the framework for managing wireless cards is called nl80211. It's netlink based, so you can use libnlto issue commands and parse answers. More information:

Currently iwis the command line utility that utilizes nl80211, so you can list available hardware, scan, etc:

Its source code is easy to study and reuse in your own project, just check out their git repo.

No API but you can try: Excecute iwconfig from a java application
没有 API，但您可以尝试：Excecute iwconfig from a java application
You can also try http://kosmosisland.com/island/david/kosmos-island-wireless.php. They have a Java Applet (with source) that monitors the Wireless Link. You can see how they did it.
您也可以尝试http://kosmosisland.com/island/david/kosmos-island-wireless.php。他们有一个 Java Applet（带有源代码）来监控无线链接。你可以看到他们是如何做到的。
