在linux下，如何实现wifi direct？

tosail 2016-11-03 09:47:11

linux下，wifi，有ap模式，和sta模式。

我用的是RT3070模组。

请问是否要加载ap的驱动和sta驱动。还有wifi direct与驱动有什么关系？

wifi direct 有有GO 和GC类似AP和STA，要使用wifi direct必须要打开wifi，打开wifi就要用到驱动。在我的认知中，同一个模组不管是什么模式都是用的同一份驱动。

wifid 在Linux上设置Wi-Fi Direct连接 Linux上的WiFi Direct 因此，我尝试使用Wifi-Direct连接两个设备。一个是装有Linux的PC，另一个是Android智能手机。我希望将Linux作为GO，将Android作为客户端。为了建立Wifi-Direct连接，我制作了一个Python脚本以使用p2p选项启动wpa_supplicant和wpa_cli。这就是在Linux中对我有效的方法。 wifid.py 它提供3个功能： setup_conf_files（） start_as_go_fedora（） start_as_go
