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.
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.
Gracias
With newer kernels the framework for managing wireless cards is called nl80211. It's netlink based, so you can use libnl to issue commands and parse answers. More information:
http://wireless.kernel.org/en/developers/Documentation/nl80211
Currently iw is the command line utility that utilizes nl80211, so you can list available hardware, scan, etc:
http://linuxwireless.org/en/users/Documentation/iw
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
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.
