wpa_supplicant wifi-Linux和Android之间的直接连接教程

我正在尝试在Android和Linux之间建立wifi直接连接.我正在使用rtl8188au.

我通过使用wpa\_supplicant找到了关于wifi直接的一些提示,所以我得到了wpa\_supplicant v2.0.这就是我为wifi-direct所做的.

1.Compiled rtl8288au driver, activated nl80211.
2.Compiled wpa_supplicant and wpa_cli for nl80211.
3.Run wpa_supplicant on linux, with option -Dnl80211. success.
4.Set ip address for wlan0.
5.Run wpa_cli, and try to connect to android device.

连接可以立即成功,但很快就会断开连接.

这是wpa\_cli日志.

wpa\_cli -p / var / run / wpa\_supplicant

有什么不对的吗？

如果是这样,我应该怎么做完整的wifi直接连接？

解决方法:

我终于找到了解决方案……

它不仅需要wpa\_supplicant,还需要iwpriv,hostapd,dhcpd.

这是我为wifi直接连接所做的.

设备模式(Linux请求连接到Android)

ifconfig wlan0 192.168.1.15 up
iwpriv wlan0 p2p_set enable=0
iwpriv wlan0 p2p_get status
iwpriv wlan0 p2p_get role
iwpriv wlan0 p2p_set enable=1
iwpriv wlan0 p2p_set intent=1
iwpriv wlan0 p2p_get status
iwpriv wlan0 p2p_set op_ch=6
iwpriv wlan0 p2p_set ssid=DIRECT-RT
iwpriv wlan0 p2p_set setDN="RTL8192CU"
iwlist wlan0 scan
iwpriv wlan0 p2p_get2 wpsCM=<MAC_ADDRESS_OF_TARGET_DEVICE>
iwpriv wlan0 p2p_get2 devN=<MAC_ADDRESS_OF_TARGET_DEVICE>
iwpriv wlan0 p2p_set prov_disc=<MAC_ADDRESS_OF_TARGET_DEVICE>
iwpriv wlan0 p2p_set got_wpsinfo=3
iwpriv wlan0 p2p_set nego=<MAC_ADDRESS_OF_TARGET_DEVICE>
wpa_supplicant -i wlan0 -c ./wpa_0_8.conf -B
wpa_cli wps_pbc <MAC_ADDRESS_OF_TARGET_DEVICE>

GO模式(Android请求连接到Linux)

iwpriv wlan0 p2p_set enable=3
iwpriv wlan0 p2p_get status 
iwpriv wlan0 p2p_get role 
iwpriv wlan0 p2p_set intent=1
iwpriv wlan0 p2p_set op_ch=6
iwpriv wlan0 p2p_set ssid=DIRECT-RT
./hostapd -B ./p2p_hostapd.conf
<<<<< Request connection from Android >>>>
iwpriv wlan0 p2p_get peer_deva
iwpriv wlan0 p2p_get req_cm
iwpriv wlan0 p2p_set got_wpsinfo=3
iwpriv wlan0 p2p_get peer_ifa
./hostapd_cli wps_pbc any
ifconfig wlan0 192.168.1.254
dhcpd

但是有一些wifi直接连接的必要条件.

您的无线驱动程序应支持nl80211.
MAKE wpa\_supplicant,hostapd时配置’nl80211’选项.
dhcpd配置文件.(dhcpd.conf,dhcpd.lease)
wpa\_supplicant,hostapd配置(conf文件)

我希望这篇文章可以帮助谁想要Linux和Android之间的wifi直接.

谢谢.
