2 项目设计和流程

2.1 编译wifi模块

参考快速入门，建议先直接编译一次所需镜像，然后使用2.1.2的方法。

2.1.1 首次编译

如果是第一次编译时就需要添加wifi模块，请检查所需编译版型的配置，配置位于openwrt-18.06/target/linux/siflower/ 文件夹下，例如sf19a28_ac28_fullmask_def.config为ac28版型的配置。查看配置并作对应修改：

CONFIG_PACKAGE_dnsmasq=y
CONFIG_PACKAGE_wireless-regdb=y
CONFIG_PACKAGE_kmod-cfg80211=y
CONFIG_PACKAGE_kmod-mac80211=y
CONFIG_PACKAGE_MAC80211_DEBUGFS=y
CONFIG_PACKAGE_MAC80211_MESH=y
CONFIG_PACKAGE_kmod-sf_smac=y
CONFIG_PACKAGE_SFSMAC_DBGINFO_ALLOCS=y
CONFIG_PACKAGE_SFUMAC_WIFI_TEST_SCRIPTS=y
CONFIG_PACKAGE_SFUMAC_WIFI_ATE_TOOLS=y
CONFIG_PACKAGE_SFUMAC_FMAC=y
CONFIG_PACKAGE_libiwinfo=y
CONFIG_PACKAGE_hostapd-common=y
CONFIG_PACKAGE_iw=y
CONFIG_WPA_MSG_MIN_PRIORITY=3
CONFIG_DRIVER_11N_SUPPORT=y
CONFIG_DRIVER_11AC_SUPPORT=y
CONFIG_PACKAGE_wpad-mini=y
CONFIG_PACKAGE_iwinfo=y

修改完成后，若编译ac28镜像,则在openwrt-18.06目录下使用./make.sh ac28即可编译，编译完成后在当前目录即可得到镜像。

2.1.2 非首次编译

如果不是第一次编译，那么可以使用make menuconfig然后选中以下内容：

Kernel modules ---> Wireless Drivers--->kmod-sf_smac  
Network--->hostapd-common
Utilities--->iwinfo  
Base system--->dnsmasq

修改完成之后保存，在openwrt-18.06目录下使用make -j V=s即可编译，镜像位于bin/siflower/openwrt-siflower-sf16a18-mpw0-squashfs-sysupgrade.bin。

2.2 wifi上层配置说明

2.2.1 wifi配置简述

SDK中的配置沿用了openwrt原始的wifi配置，可以参考openwrt-wifi配置。配置文件在镜像中的位置为/etc/config/wireless，典型的配置如下：

config wifi-device 'radio0'
        option type 'mac80211'
        option country 'CN'
        option txpower_lvl '2'
        option channel '1'
        option band '2.4G'
        option hwmode '11g'
        option noscan '0'
        option netisolate '0'
        option max_all_num_sta '64'
        option path 'platform/11000000.wifi-lb'
        option htmode 'HT20'
        option disabled '0'

config wifi-iface 'default_radio0'
        option device 'radio0'
        option network 'lan'
        option mode 'ap'
        option ssid 'SiWiFi-9630-2.4G'
        option encryption 'none'
        option key '12345678'
        option hidden '0'
        option ifname 'wlan0'
        option wpa_group_rekey '3600'
        option isolate '0'
        option group '1'
        option netisolate '0'

如图，配置分为两层，由config后的第一个字符串来进行区分。
其中，wifi-device对应具体硬件的wifi驱动设备,我们支持2.4G和5G两种device；wifi-iface对应单个wifi接口，与单个ssid（即wifi名称）相对应，一个wifi-device下面可以配置多个wifi-iface，最多支持4个。

2.2.2 配置选项说明

2.2.2.1 wifi-device配置选项

配置中的同一个config段的option ***** '*****'先后顺序不影响配置。

注：默认值为”/”时表示该选项不一定会出现，只有在进行了某些设置的情况下才会出现；默认值为”-“时表示2.4G和5G有差异，将在描述里进行说明。

选项	值类型	默认值	描述
wifi-device	string	radio0	驱动设备名称
type	string	mac80211	驱动类型，目前固定为”mac80211”。
country	string	CN	国家码，2个大写字母，默认为CN，表示中国（China），国家码会影响信道和发射功率。其他常见国家代码参见2.2.5节。
channel	string/int	-	信道，默认2.4G为信道1，值为”auto”时表示自动选取最优信道，不同国家信道限制不同，如中国地区2.4G信道为1~13 ，5G信道为36~64 、149~165。
txpower_lvl	int	2	发射功率，可设值为0、1、2。该值越大，表示功率越大。
max_all_num_sta	int	64	驱动所能连接设备个数的最大值
netisolate	boolean	0	设备隔离，如果设置为1，则从该device下的设备无法访问同一网桥（bridge）中其它bssid的设备。
noscan	boolean	0	值为1时，表示不扫描周围信道。
path	string	-	对应驱动在/sys/devices/下的节点，一般不作修改。默认2.4G为”platform/11000000.wifi-lb”，5G为”platform/17800000.wifi-hb”。
htmode	string	20MHz	带宽模式，2.4G支持20MHz/40MHz，5G支持20MHz/40MHz/80MHz。
hwmode	string	-	wifi工作模式，2.4G支持11b/11g/11n，5G支持11n/11a/11ac，最终的模式是由htmode和hwmode共同决定的，参见2.2.3节。
disabled	boolean	0	0表示启用该驱动设备，1表示关闭该驱动设备。
ht_coex	boolean	/	值为1时，表示带宽20MHZ/40MHZ共存，与htmode有一定联系，参见2.2.3节。

2.2.2.2 wifi-iface配置选项

选项	值类型	默认值	描述
wifi-iface	string	default_radio0	wifi-iface节点名称
device	string	-	对应wifi-device驱动名称，默认2.4G为radio0，5G为radio1。
ifname	string	wlan0	网卡(iface)的名称，使用ifconfig时会显示对应名称。
network	string	lan	对应的网桥（bridge）名称，如果需要把wifi加入到lan口则配置该值为lan。
mode	string	ap (sta、minotor)	ap对应热点，sta对应站点（station），monitor对应监听模式。默认为ap模式。
ssid	string	SiWIFi-**	wifi的名称，最大不超过32位。支持中文，但在串口会显示为”…“。默认名称中的数字来源于mac地址。
encryption	string	none	加密方式，”none”表示不加密，如果想加密，建议改成”psk2+ccmp”，具体加密方式见2.2.4节。
key	string	12345678	wifi密码，psk2需设置8位以上。当加密方式为不加密（none）时此选项不生效，而其他加密方式必须配置密码。
hidden	boolean	0	是否隐藏热点，1表示隐藏，0表示不隐藏。隐藏后设备只能通过手动添加SSID才能连接wifi。
wpa_group_rekey	int	3600	刷新GTK（广播/多播加密密钥）的时间间隔（以秒为单位）。若不设置此项，则使用CCMP / GCMP作为组密码时默认为86400秒（每天一次），使用TKIP作为组密码时默认为600秒（每10分钟一次）。
isolate	boolean	0	连接此wifi的各设备之间是否隔离，1表示隔离，0表示不隔离。
group	int	-	bridge中的分组，各个不同的group之间在bridge中是不能互相访问的。默认2.4G为0，5G为1。
netisolate	boolean	0	如果配置为1，则从该bssid下的设备无法访问同一bridge中其它bssid的设备。

其他更多选项可参考openwrt官方配置介绍。

2.2.3 htmode和hwmode对应关系

不同的WiFi协议决定了hwmode、htmode可以配置的选项，下面列举不同模式的配置要求。

2.2.3.1 2.4G配置

2.4G模式	配置	描述
11b	option hwmode 11b	该模式下option htmode必须删除该模式下option ht_coex必须删除
11g	option hwmode 11g	该模式下option htmode必须删除该模式下option ht_coex必须删除

2.2.3.2 5G配置

5G模式	配置	描述
11a	option hwmode 11a	该模式下option htmode必须删除该模式下option ht_coex必须删除
11n	option hwmode 11a option htmode HT20 （或option htmode HT40） option ht_coex 1	当ht_coex的值为1时，处于20MHz/40MHz混合模式；当ht_coex的值为0时，htmode的值就是频宽
11ac	option hwmode 11a option htmode VHT20 (或option htmode VHT40 或option htmode VHT80)	该模式下option ht_coex必须删除

2.2.4 encryption加密方式

2.3 wifi配置方法

2.3.1 如何修改配置

1、直接修改配置文件/etc/config/wireless
2、通过uci命令修改，参考config文件配置手册

2.3.2 如何使配置生效

修改配置后，需要使用”wifi”相关指令使wireless配置生效，指令执行脚本位于/sbin/wifi。

指令	参数	描述
wifi	-	不加任何参数，则重新启用”全部wifi”
wifi	config	当”/etc/config/wireless”文件不存在时重新生成该文件
wifi	reload	重新启用”配置有所更改的wifi”
wifi	down	关闭全部wifi
wifi	up	启用全部wifi
wifi	status	以json串的方式打印wifi信息

示例1 使用uci指令修改2.4G信道：

root@OpenWrt:/# uci show wireless.radio0.channel
wireless.radio0.channel='auto'
root@OpenWrt:/# uci set wireless.radio0.channel='5'
root@OpenWrt:/# uci commit wireless
root@OpenWrt:/# wifi reload
root@OpenWrt:/# [59354.934536] lmac[0] vif_mgmt_register, vif_type : 2

[59354.996105] br-lan: port 3(wlan0) entered blocking state
[59355.001547] br-lan: port 3(wlan0) entered forwarding state

示例2 生成wireless文件

root@OpenWrt:/# ls etc/config/wireless
ls: etc/config/wireless: No such file or directory
root@OpenWrt:/# wifi config
root@OpenWrt:/# ls etc/config/wireless
etc/config/wireless

2.3.3 查看wifi信息

使用”iw”指令可查看wifi相关信息，下面列出常见的iw指令。

指令	参数	描述	示例
iwinfo	/	列出所有无线网络信息	iwinfo
iw	<ifname> info	列出单个wifi信息	iw wlan0 info
iw	list	列出所有无线设备信息	iw list
iw	<ifname> scan	扫描周围信号	iw wlan1 scan

2.3.4 新增节点方法（ap、sta）

2.3.4.1 新增ap节点

在/etc/config/wireless中增加一段即可，最简单的一种配置如下：

  config wifi-iface
        option device 'radio0'
        option network 'lan'  
        option mode 'ap'
        option ssid 'SiWiFi-new-ap'
        option encryption 'psk2+ccmp'
        option key '12345678'
        option ifname 'wlan0-1'

2.3.4.2 新增sta节点

在/etc/config/wireless中增加一段即可，实例如下：

config wifi-iface
        option key '12345678'
        option ifname 'sfi0'
        option network 'wwan'
        option encryption 'psk2+ccmp'
        option device 'radio0'
        option mode 'sta'
        option bssid 'A8:5A:F3:00:02:3F'
        option ssid 'SiWiFi-023c-2.4G-8_1'

配置说明

选项	值类型	默认值	描述
ssid	string	/	所需连接的目标热点名称，可通过iw <ifname> scan的指令得到
bssid	string	/	目标热点的bssid，可通过iw <ifname> scan的指令得到，格式为 `:::::`
encryption	string	/	目标热点的加密方式
key	string	/	目标热点的密码
ifname	string	-	该值会影响luci的网络接口能否把他识别成一个无线interface，影响网页的信息获取和设置。目前2.4g默认使用的名字为sfi0,5g为sfi1。
network	string	wwan	网络配置，和/etc/config/network的配置相关
device	string	-	使用的驱动设备名称。 2.4G默认使用radio0，5G为radio1
mode	string	sta	表示sta模式

2.4 wifi配置生效流程

2.4.1 如何修改默认配置？

在板子上生成默认配置的脚本为lib/wifi/mac80211.sh，其在源码中位于package/kernel/mac80211/files/lib/wifi/mac80211.sh。

示例将wifi的默认加密方式从不加密改为psk2加密

chentong@ubuntu:~/p-tmp/openwrt-18.06$ git diff package/kernel/mac80211/files/lib/wifi/mac80211.sh
diff --git a/package/kernel/mac80211/files/lib/wifi/mac80211.sh b/package/kernel/mac80211/files/lib/wifi/mac80211.sh

                        set wireless.default_radio${devidx}.ifname=wlan${devidx}

2.4.2 默认配置生成后被应用到哪里？

/etc/config/wirelesss会被netifd和hostapd使用。
对于netifd，将直接读取wireless的配置；
对于hostapd，会由脚本/lib/netifd/wireless/mac80211.sh读取配置，生成配置文件/var/run/hostapd-phy*.conf以供hostapd使用，该脚本在源码中位于package/kernel/mac80211/files/lib/netifd/wireless/mac80211.sh。

2.4.3 wifi配置流程图

2.5.2.2 wifi驱动模块的相关指令

指令	参数	描述
insmod	“模块名称” …	加载该模块，简单指令如`insmod /lib/modules/4.14.90/startcore.ko` (或`insmod startcore.ko`或`insmod startcore`)。需要注意的是，有些模块加载需要附加较多参数，建议使用sfwifi指令进行模块操作。
rmmod	“模块名称” …	卸载该模块
modinfo	“模块名称” …	显示该模块相关信息
sfwifi	remove	移除wifi驱动相关模块，包括sf16a18_rf.ko、startcore.ko、sf16a18_fmac.ko
sfwifi	reload	重新加载wifi驱动模块
sfwifi	reset	重新启动wifi驱动相关模块

2.5.2.3 设置wifi驱动不自动加载

如果想开机时不自动加载wifi驱动，可用如下方法：

第一步，在package/kernel/sf_smac/config/99_rf_misc注释掉下面这一行

#boot_hook_add preinit_main insmod_rf

第二步，在package/kernel/sf_smac/Makefile注释掉以下部分

#ifndef CONFIG_PACKAGE_SFSMAC_HB_LA_ENABLE
#   echo 'boot_hook_add preinit_main insmod_$(SF_UMAC_TYPE)_lb' >> $(1)/lib/preinit/99_rf_misc
#endif
#ifndef CONFIG_PACKAGE_SFSMAC_LB_LA_ENABLE
#   echo 'boot_hook_add preinit_main insmod_$(SF_UMAC_TYPE)_hb' >> $(1)/lib/preinit/99_rf_misc
#endif

需要时可以使用sfwifi reset fmac来加载驱动，启用wifi。

2.5.3 wifi信号优化

可以尝试如下方法改善wifi信号:

更换wifi信道为自动（auto），自动信道会选择最合适的信道
增大发射功率txpower_lvl
尽量避开障碍物

3 测试用例

3.2 wifi压力测试

3.2.1 wifi_onoff测试

测试方法

在板子起来后，运行wifi_onoff.sh ‘band’，可进行wifi-device的不停重载。’band’可选择2或者5，例如wifi_onoff.sh 2。

示例

root@OpenWrt:/# wifi_onoff.sh 2

[77197.178626] br-lan: port 3(wlan0) entered disabled state
[77197.185663] device wlan0 entered promiscuous mode
=======radio0 turn on success=======

...

测试结果分析

测试不中断则为正常; 测试失败时会持续打印（根目录下有日志文件on_off.log）：

====cycle is $x===radio1 turn on failed,continue $y times=======

（$x: 压力测试的次数 $y: check测试结果的次数）

若最后出现

=======after retest radio0 turn off success=======

也是正常情况,这是由于检测信道造成的。

3.2.2 sfwifi reset测试

测试方法

板子起来后使用指令sfwifi stress fmac，该指令会不停的重启wifi驱动（sfwifi reset fmac）。

示例

root@OpenWrt:/# sfwifi stress fmac

测试结果分析

测试不中断则为正常; 若中断，出错信息在/tmp/sfwifi.log。

3.2.3 双band iperf测试

测试方法

两台机器，一台作为master，一台作为slave 进入串口，执行顺序如下：

master:setup-wifi.sh master 456 // 455是可变序号，不同组测试用不同序号

slave:setup-wifi.sh slave 456

master:run-wifi.sh master

slave:run-wifi.sh slave

两侧均出现速度代表测试已正常开始

示例

测试结果分析

测试未中断即为正常。

FAQ

Q1、为什么手机连接wifi时拿不到IP地址?

A：检测dhcp服务是否开启（查看进程里是否有dnsmasq），尝试使用/etc/init.d/dnsmasq restart重启dhcp服务；检测dhcp服务池是否已满。

Q2、为什么wifi-iface里设置了key，但是手机不需要密码就能连接？

A：检查encryption后的字符串是否和2.2.4节列表一致，错误的字符串会导致wifi设置成开放模式。
