4. 使用

其中 wifi_sta_ap6212.sh 用于连接热点;wifi_ap_ap6212.sh 用于开启热点。

4.1 接入热点

如需接入一个新热点，修改脚本wifi_sta_ap6212.sh，找到wpa_passphrase “wifi_2.4G” “12345678” >> /tmp/run/wpa_supplicant/wpa.conf 部分，修改对应的名称和密码。

如名称为111 ，密码为12345678，则修改为 wpa_passphrase “111” “12345678” >> /tmp/run/wpa_supplicant/wpa.conf

4.2 开启热点

如需开启一个新热点，需要修改脚本wifi_ap_ap6212.sh，找到 echo “ssid=111_test” >> /var/run/hostapd/hostapd.conf echo “wpa_passphrase=12345678” >> /var/run/hostapd/hostapd.conf 部分，修改对应的名称和密码。 如名称为111，密码为12345678，则修改为 echo "ssid=111 " >> /var/run/hostapd/hostapd.conf echo “wpa_passphrase=12345678” >> /var/run/hostapd/hostapd.conf

4.3 开启热点命令

root@Ubuntu:/etc/firmware/ap6212a# ./wifi_ap_ap6212.sh

4.4 连接热点命令

root@Ubuntu:/etc/firmware/ap6212a# ./wifi_sta_ap6212.sh

如不能正常上网，请查看是否修改正确。
