[经验] 【HarmonyOS HiSpark IPC DIY Camera】hi3518-wifi配置与使用

主要是修改和3518相关的wpa_supplicant.conf、hostapd.conf两个文件，对wIFi相关的ssid、passwd等进行配置。
Z:\code3518\applications\sample\camera\communication\hostapd\config\hostapd.conf
【修改ap模式的配置】将以下配置写到配置文件hostapd.conf
interface=wlan0
driver=hdf wifi
ctrl_interface=udp
ssid=testap
hw_mode=g
channel=1
ignore_broadcast_ssid=0
#下面是wpa2-psk类型加密的配置
#如果不需要加密可以删除
auth_algs=1
wpa=2
wpa_passphrase=12345678
rsn_pairwise=CCMP

Z:\code3518\applications\sample\camera\communication\wpa_supplicant\config\wpa_supplicant.conf
【修改station模式的配置】将以下配置写到配置文件wpa_supplicant.conf
country=GB
ctrl_interface=udp
network={
ssid="loveu99"
psk="loveyou99"
}

country=GB
ctrl_inteRFace=udp
network={
#要连接的SSID
ssid="example"
#如果不需要加密就写key_mgmt=NONE
#key_mgmt=NONE
#如果需要加密就写这行密码
psk="12345678"
}

Z:\code3518\applications\sample\camera\communication\wpa_supplicant\src\wpa_sample.c
【编译生成wifi可执行文件】请参考以下示例代码编译可执行程序wpa_supplicant：（SDK里面有这些代码，不做修改）
路径./applications/sample/camera/communication/wpa_supplicant/src/wpa_sample.c

Z:\code3518\applications\sample\camera\communication\wpa_supplicant\BUILD.gn

Z:\code3518\applications\sample\camera\communication\BUILD.gn
路径./applications/sample/camera/communication/wpa_supplicant目录下面的BUILD.gn文件（不做修改）

Z:\code3518\applications\sample\camera\communication\BUILD.gn
路径./applications/sample/camera/communication目录下面的BUILD.gn文件

]
}

generate_notice_file("communication_sample") {

"//third_party/wpa_supplicant/wpa_supplicant-2.9/wpa_supplicant",
]
}

Z:\code3518\build\lite\product\ipcamera_hi3518ev300.json
路径./build/lite/product/ipcamera_hi3518ev300.json（不做修改）

2、【使用方法】
【WIFI设备检测】进入OHOS界面后，输入
ifconfig
检查wlan0网口是否加载正常，加载成功标识如下：
OHOS # ifconfig
wlan0 ip:0.0.0.0 netmask:0.0.0.0 gateway:0.0.0.0
HWaddr 0a:11:31:aa:7e:1a MTU:1500 Stop Link UP
lo ip:127.0.0.1 netmask:255.0.0.0 gateway:127.0.0.1
ip6: ::1/64
HWaddr 00 MTU:16436 Running Link UP

将wpa_supplicant、wpa_supplicant.conf、hostapd.conf拷贝到单板TF卡中，在系统上电之前插入到TF卡的卡槽。
【启动sta的命令】
./sdcard/wpa_supplicant -i wlan0 -c /sdcard/wpa_supplicant.conf

测试步骤，打开红米Note8 Pro的流量，并设置热点为2.4GHz模式。
SSID：loveu99
passwd：loveyou99

测试结果：可以获取局域网IP地址：192.168.43.85
但是ping百度之后内核崩溃。
最初测试我是连接公司的网络，以为公司的网络有所限制，所以特地使用手机虚拟了一个热点，还是异常。
可能是配置的问题或者华为海思新出的WIFI芯片Hi3881的驱动程序BUG所导致！
