1、wireless-tools测试不加密AP
1. 从www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html 下载wireless_tools.30.pre9.tar.gz， 此版本支持non-ASCII char in ESSID
2. 解压到mydroid/external/wireless-tools目录
3. 创建Android.mk，内容如下
LOCAL_PATH:= $(call my-dir)
################## build iwlib ###################
include $(CLEAR_VARS)
LOCAL_SRC_FILES := iwlib.c
LOCAL_CFLAGS += -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wpointer-arith -Wcast-qual -Winline -MMD -fPIC
LOCAL_MODULE:= libiw
LOCAL_STATIC_LIBRARIES := libcutils libc libm
include $(BUILD_STATIC_LIBRARY)
################## build iwconfig ###################
include $(CLEAR_VARS)
LOCAL_SRC_FILES := iwconfig.c
LOCAL_CFLAGS += -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wpointer-arith -Wcast-qual -Winline -MMD -fPIC
LOCAL_MODULE:= iwconfig
LOCAL_STATIC_LIBRARIES := libcutils libc libm libiw
#LOCAL_FORCE_STATIC_EXECUTABLE := true
LOCAL_MODULE_PATH := $(TARGET_OUT_OPTIONAL_EXECUTABLES) # install to system/xbin
#LOCAL_UNSTRIPPED_PATH := $(TARGET_ROOT_OUT_UNSTRIPPED)
#LOCAL_MODULE_TAGS := eng user
include $(BUILD_EXECUTABLE)
################## build iwlist ###################
include $(CLEAR_VARS)
LOCAL_SRC_FILES := iwlist.c iwlib.h
LOCAL_CFLAGS += -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wpointer-arith -Wcast-qual -Winline -MMD -fPIC
LOCAL_MODULE:= iwlist
LOCAL_STATIC_LIBRARIES := libcutils libc libm libiw
#LOCAL_FORCE_STATIC_EXECUTABLE := true
LOCAL_MODULE_PATH := $(TARGET_OUT_OPTIONAL_EXECUTABLES) # install to system/xbin
#LOCAL_UNSTRIPPED_PATH := $(TARGET_ROOT_OUT_UNSTRIPPED)
#LOCAL_MODULE_TAGS := eng user
include $(BUILD_EXECUTABLE)4. 修改
将wireless.22.h 更名为wireless.h
修改ifrename.c 增加getline的函数，代码可以从external/genext2fs/genext2fs.c中获得,注意里边是用宏把另一个函数传给getline
修改iwlib.h，将#include <net/ethernet.h>改为#include <net/if_ether.h>
5. 编译
robin@robin-virtual-machine:~/mydroid/external/wireless-tools$ . ../../build/envsetup.sh
robin@robin-virtual-machine:~/mydroid/external/wireless-tools$ mm
编译出错：
external/wireless_tools.29/iwlist.c: In function 'print_scanning_info':
external/wireless_tools.29/iwlist.c:633:7: error: 'IW_EV_LCP_PK2_LEN' undeclared (first use in this function)
external/wireless_tools.29/iwlist.c:633:7: note: each undeclared identifier is reported only once for each function it appears in
external/wireless_tools.29/iwlist.c:633:50: error: 'IW_EV_POINT_PK2_LEN' undeclared (first use in this function)
make: *** [out/target/product/sabresd_6dq/obj/EXECUTABLES/iwlist_intermediates/iwlist.o] Error 1
解决办法：
1> 在wireless.h最后添加以下两句：
#undef IW_EV_LCP_PK_LEN
#undef IW_EV_POINT_PK_LEN
################## build iwlist ###################
include $(CLEAR_VARS)
LOCAL_SRC_FILES := iwlist.c #iwlib.h
重新mm

编译通过在out/target/product/sabresd_6dq/symbols/system/xbin中生成了iwconfig和iwlist
6.重新编译system.img烧入板子
robin@robin-virtual-machine:make snod
7.上电测试
由于wireless_tools只能测试未加密的热点，所以手机分享热点后

2、wpa_supplicant测试加密AP
通过上面wireless-tools的测试，已经证明WiFi驱动层是OK了的，但因为现在大多数AP都是加密的 ，所以就需要用到wpa_supplicant，我们编译android系统时，就已经把自带的wpa_supplicant和wpa_cli编译好并放到system/bin目录下了
1>配置wpa_supplicant
修改out目录下 android_kk4.4.2/out/target/product/sabresd_6dq/system/etc/wifi/wpa_supplicant.conf 文件
#添加如下代码
network={
ssid="TP-LINK_AUTO"
psk="86676890"
key_mgmt=WPA-PSK
priority=2
}
#明文连接是不被路由器所接受的，所以还得将密码转为psk密码
#密文转换需要用到wpa_passphrase，但Android并没有自带，移植了半天都没能实现，所以在Ubuntu中实行转换：
#执行：wpa_passphrase TP-LINK_AUTO 86676890
#转换后如下：
network={
ssid="TP-LINK_AUTO"
#psk="86676890"
psk=66ce62f4531249341e240baca32f3af523074d74a099f77d3c81f983c4a5ae17
key_mgmt=WPA-PSK
priority=2
}
2>连接AP（吐槽：真心蛋疼的编辑器，每行的空格，编辑时好好的，发表显示就成换行了）
在板子的终端输入： wpa_supplicant -Dnl80211 -iwlan0 -c/system/etc/wifi/wpa_supplicant.conf &
打印一系列信息，如下：
3>分配IP
命令：ifconfig wlan0 192.168.1.108
测试：ping 192.168.1.107测试结果如下：
wpa_supplicant测试成功！接下来的工作就是将wpa_supplicant和Android层对接了。
