iMX6ULL开发板WIFI功能测试(二）

一、iMX6ULL开发板 WIFI 功能测试

WiFi支持：

1、 USB WIFI RTL8188eus使用

说明： USB WIFI无线局域网卡是选配模块 ，如若有需求，请联系飞凌嵌入式官网在线客服。

以下对wifi模块在STA模式下，连接到无线网络的测试：

步骤1：iMX6ULL开发板上电，启动Linux系统。

步骤2：连接USB WIFI到飞凌iMX6ULL开发板的USB Host接口

步骤 3 ：按照如下格式输入相应的参数：

-i表示wifi型号；

-s表示wifi热点名称；

-p表示密码，若无密码输入-p NONE；

路由器采用wpa加密方式。具体操作指令可查看wifi.sh脚本。

连接打印内容如下：

root@fl-imx6ull:~# fltest_cmd_wifi.sh -i 8188 -s forlinx -p xxxx

打印信息如下：

wifi 8188
