WIFI on:

adb shell svc wifi enable

WIFI off:

adb shell svc wifi disable

使用wpa_supplicant, wpa_cli连接wifi

如果对应的命令没有需要从源码编译后，导入到/system/bin目录下，修改权限755
dhcpcd目录 \external\dhcpcd-6.8.2
wpa_cli \external\wpa_supplicant_8 编译后会生成该文件

echo $addID
wpa_cli set_net ${addID} ssid "\"${ssid}\""
wpa_cli set_net ${addID} psk "\"${psk}\""
wpa_cli select_net ${addID}
wpa_cli enable_net ${addID}

dhcpcd wlan0
