唠叨几句

MT7688这类“路由器”SOC最大的强项还是网络上,互联效果比普通SOC好很多,这一节讲讲常用的WI-FI操作。

扫描周围AP列表

aps命令运行之后大约5秒,在控制台打印扫描到的结果。

让MT7688通过WI-FI联网

wifimode apsta ssid key命令,ssid和key分别是你的家庭Wi-Fi用户名和密码。

看到了APCLI LINK UP,那么WIFI就连接上了。

检查是否链接好上级AP

ap_client命令用来检查是否连上上级AP,返回“ok”代表已经连接好,否则返回"no"

root@Widora:/# ap_client 
ok
root@Widora:/# ping qq.com
