手动加载WiFi驱动
加载驱动
insmod /system/8812au.v2.ko
启动wlan0
busybox ifconfig wlan0 up
禁用wlan0
busybox ifconfig wlan0 down
卸载驱动
rmmod 8812au
wifi节点加载
启动wlan0之前可以先使用ifconfig -a wlan0查看wlan0 节点是否存在,
127|rk3399_mid:/ # ifconfig -a wlan0
wlan0 Link encap:Ethernet HWaddr d4:b7:61:9f:3a:3c
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 TX bytes:0
若不存在,则需先启动p2p_supp_rtl服务创建wlan0节点
开启p2p_supp_rtl服务
setprop ctl.start p2p_supp_rtl
关闭p2p_supp_rtl服务
setprop ctl.stop p2p_supp_rtl
p2p_supp_rtl服务不支持命令开启
usbwifi开启后连接网络,需要wpa_supplicant服务支持
开启wpa_supplicant服务
setprop ctl.start wpa_supplicant
关闭wpa_supplicant服务
setprop ctl.stop wpa_supplicant
wpa_supplicant服务可以使用命令开启
查找wpa_supplicant服务
service wpa_supplicant /system/bin/wpa_supplicant
-iwlan0 -Dnl80211 -c/data/misc/wifi/wpa_supplicant.conf \
-I/system/etc/wifi/wpa_supplicant_overlay.conf \
-e/data/misc/wifi/entropy.bin -O/data/misc/wifi/sockets \
-g@android:wpa_wlan0
输入命令开启wpa_supplicant服务
/system/bin/wpa_supplicant -iwlan0 -Dnl80211 -c/data/misc/wifi/wpa_supplicant.conf -I/system/etc/wifi/wpa_supplicant_overlay.conf -e/data/misc/wifi/entropy.bin -O/data/misc/wifi/sockets -g@android:wpa_wlan0 -dd
-dd 使用logcat查看时打开与wpa_supplicant运行时输出的log
例如:
logcat -c
./wpa_supplicant
logcat 只查看与wpa_supplicant运行时的log
iw命令简单使用
扫描wifi并打印出扫描到wifi的SSID
iw dev wlan0 scan |grep "SSID:" -i
连接wifi xmzw
iw wlan0 connect xmzw
wpa_cli命令使用
打开debuglog
wpa_cli -iwlan0 -p/data/misc/wifi/sockets log_level debug
扫描AP
wpa_cli -iwlan0 scan
显示扫描结果
wpa_cli -iwlan0 scan_result
例:rk3399_mid:/ # wpa_cli -iwlan0 scan
OK
rk3399_mid:/ # wpa_cli -iwlan0 scan_results
