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。
