两个WIFI-TTL互相通讯
本帖最后由 Makelin 于 2017-12-13 14:39 编辑先上图：
两个wifi-ttl需要互相通讯需要一块设置成ap模式并且建立tcpserver，另外一块设置成sta模式，连接这个ap并且设置为tcpclient模式。这样两个wifi-ttl的串口就能互相通讯了。网络示意图如下http://bbs.doit.am/data/attachment/forum/201710/16/102311wkmo03xs00ixeffn.png
注：
AP模式: AccessPoint，提供无线接入服务，允许其它无线设备接入，提供数据访问，一般的无线路由/网桥工作在该模式下。AP和AP之间允许相互连接Sta模式: Station, 类似于无线终端，sta本身并不接受无线的接入，它可以连接到AP，一般无线网卡即工作在该模式。设置步骤如下WIFI-TTL模块A设置为ap模式并且建立tcpserverhttp://bbs.doit.am/data/attachment/forum/201710/16/103042qkhsom6sogffkk6s.png设置建立tcpserverhttp://bbs.doit.am/data/attachment/forum/201710/16/103042g50kce3h3g9433yp.pngWIFI-TTL模块B打开sta模式，连接这个模块A的热点

保存完成之后，模块B会连接模块A的热点，两个模块之间即可用串口互发数据http://bbs.doit.am/data/attachment/forum/201710/16/104029k6pp6z6j88gk2bbb.png
这个可以用来两个arduino板之间wifi连接通信吗？
