hi3519v101平台搭建hostapd

以前是有建立过在Ubuntu下面建立hostapd,现在海思项目有这么个需求,需要移植.

1.wifi驱动移植,看上章.

2.我们需要工具:hostapd热点;udhcpd动态分配ip;wpa_supplicant配置sta,可以连接wifi.

      但是hostapd,wap_supplicant依赖于ssl和nl库.我所用的库openssl-1.0.2s , libnl-3.4.0, hostapd-2.8, udhcp-0.9.8 ,wpa_supplicant-2.8都是在他们官网上下载的.

       下面是Makefile:

###########编译openssl,去掉-m64,libclean用:rm -rf;因为我编译出现了错误,因此修改.

libopenssl_clean:
    pushd $(OPENSSL_SOURCE_DIR);make clean;popd
    rm -rf $(SUB_OPENSSL_INSTALL_DIR)

####编译nl3.4库

libnl3_4:
    mkdir -p $(SUB_LIBNL_INSTALL_DIR);
    pushd $(LIBNL_SOURCE_DIR); ./configure --host=arm-hisiv500-linux --prefix=$(SUB_LIBNL_INSTALL_DIR);make;make install;popd
libnl3_4_clean:
    pushd $(LIBNL_SOURCE_DIR);make clean;popd
    rm -rf $(SUB_LIBNL_INSTALL_DIR)

########下面3个目录,Makefile需要修改:hostapd和wpa_supplicant修改:CC=arm-hisiv200-linux-gcc     ;    udhcpd修改:CROSS_COMPILE=arm-hisiv200-linux-

#######对于编译hostapd和wpa_supplicant,    需要对他们目录下的.config文件添加头文件和库路径:ssl和nl的库

#指定网卡驱动。

#ieee80211n=1
#802.11n标准,支持2.4,5G。100M+速率。

#wmm_enabled=1
#音视频媒体优先

channel=1

#无线网卡选用1信道,一般为11.如2.4G(2.40-2.48)有14个信道(一个channel=22mhz),channel之间也是有重叠处,1-6-11不重叠。5g又有:34,36,38...64,100,104,108...140,149,153,157,161.

#channel与hw_mode有密切的关系。如果channel与hw_mode不一致会导致AP启动失败。mode=1 chan=1-11(2.4g),mode=2 chan=36-165(5g)。如果用2.4gchannel对应的hw_mode=g,5gchannel对应的hw_mode=a.      802.11协议指定了802.11a对应5g,802.11g对应2g,其中802.11b也是2g,802.11n都支持。参考文档:http://wenku.baidu.com/link?url=K-I08AFxnJa0V3Y_2bW6EyvktIbkBUUfxpW6ZsjGdtD6Oxtw7kRR6x-nu2SaDeYRTJT_WdeexaTP270LiWYbSyG92u13w5t_F4bZmSPQPri

ignore_broadcast_ssid=0
#This enables/disables broadcasting the ssid,1 disable.如果=0,广播ssid,sta可以扫描到他。=1不广播,扫描不到他。

#WPA=0无加密

wpa_passphrase=12345678
#wpa密码

max_num_sta=5
#最多可以连接5个无线设备。


auth_algs=1

#auth_algs=1 只支持 WPA 身份验证算法。auth_algs=2 表示支持 WEP。永远不要使用有线等效加密 (wired equivalent privacy, WEP),因为它非常容易破解,并且多年前就已经被完全破解了。auth_algs=3 表示支持这两种方式。
