大家好
我想请问用wpa_supplicant建立wifi p2p连线的问题
[问题]
我用笔电双系统的win7配合intel的wifi p2p软件，
我可以用手机的wifi direct搜寻到NB。
但是当我使用Linux时，在wpa_cli中打p2p_find [timeout]，
会直接跳出FAIL。我启动wpa_supplicant的debug mode (wpa_supplicant ... -dt)，
在wpa_cli出现FAIL时并没有跳出错误或警告讯息
想请教诸位前辈这种状况我应该朝那边走？
我不清楚问题点到底是在driver不支援还是wpa_supplicant设定有问题，
还是在其他地方...Orz
[网络资讯]
有人说 $ iw list吐出来的讯息中，
supported interface mode没有P2P_GO & P2P_client就是设备不支援
=> 不过win7的环境可以用p2p搜寻
=> 另外想请教，iw list是显示wifi chip的资讯还是driver看到的资讯？
iwlwifi-1000 (intel wireless driver)本身不支援P2P
Linux wireless上提到的
=> P2P我以为可以靠更上层的软件解决，还是这driver不支援就没办法？
wpa_supplicant的README本身并没有提到这点，他只有说:
Linux drivers that support cfg80211/nl80211. Even though there are
number of driver specific interface included in wpa_supplicant, please
note that Linux drivers are moving to use generic wireless configuration
interface driver_nl80211 (-Dnl80211 on wpa_supplicant command line)
should be the default option to start with before falling back to driver
specific interface.
Linux drivers that support WPA/WPA2 configuration with the generic
Linux wireless extensions (WE-18 or newer). Obsoleted by nl80211.
In theory, any driver that supports Linux wireless extensions can be
used with IEEE 802.1X (i.e., not WPA) when using ap_scan=0 option in
configuration file.
我自己是比较偏向wpa_supplicant的设定是不是有问题, 设定档如下(.config)
