This method is a good solution to reconnect WiFi to ESP8266 NodeMCU if the connection loses accidentally. But with this method, we have to pollif ((WiFi.status() != WL_CONNECTED) && (current_time – previous_time >=delay))condition on every execution of loop(). The alternative toloop(...

NodeMCU就是这样的一款工具，一块基于LUA固件的ESP8266 WiFi SOC也才4美元左右。
wifiManager.setConfigPortalTimeout(180); which will wait 3 minutes (180 seconds). When the time passes, the autoConnect function will return, no matter the outcome. Check for connection and if it's still not established do whatever is needed (on some modules I restart them to retry, on ...
考验WiFi运行稳定性有很多方法,玩esp8266模块就是其中一种方法 这种方法可以用来测试网络稳定性,但是也仅限此用途 固件来自失传技术研究所252424140 简单说一下制作方法和注意事项 esp8266_deauther是可以使用arduino开发的因此也是开源的我们需要准备arduion IDE、esp8266开发包、nodemcu一块 打包好的固件文件ESP8266DEAUTHE...
