使用Tina-SDK支持启动WiFi

Wifi配网

1.启动WiFi

root@TinaLinux:~# ifconfig wlan0 up
[ 1311.470054] ieee80211_do_open: vif_type=2, p2p=0, ch=3, addr=08:f9:56:88:5c:46

root@TinaLinux:~# ifconfig -a

2.开发板如下图所示接入天线

YuzukiHD-Lizard-12-1-wifi

3.扫描WiFi

root@TinaLinux:/# iw wlan0 scan | grep "SSID"
        SSID: Programmers

4.填写WiFi密码

root@TinaLinux:/# vim /etc/wpa_supplicant.conf

ctrl_interface=/var/log/wpa_supplicant
update_config=1

network={
    ssid="WiFi名"
    psk="密码"
}

示例：
ctrl_interface=/var/log/wpa_supplicant
update_config=1

network={
    ssid="test"
    psk="12345678"
}

5.连接网络

连接前需要创建socket通信的目录

root@TinaLinux:/# mkdir -p /var/log/wpa_supplicant
root@TinaLinux:/# wpa_supplicant -B -c /etc/wpa_supplicant.conf -i wlan0
Successfully initialized wpa_supplicant
root@TinaLinux:/# udhcpc -i wlan0
