I myself think it is probably getting stuck in the reconnect() function, ![]() I would appreciate any insights as to why this is happening. As the documentation of this board online can be a little confusing, the purpose of this tutorial is to combine and simplify the steps needed to setup this board for development. One of my Wemos' does not want to reconnect after dropping Wifi (router issue). The WeMos D1 is a ESP8266 WiFi based board that uses the Arduino layout with a operating voltage of 3.3V.
