Can a NodeMCU automatically reconnect to a WiFi router?
The ESP8266 has the ability to automatically reconnect to your router in case of a Wi-Fi outage. For example, if the ESP8266 is connected to your router and you suddenly turn it off, when it goes back on, the ESP8266 can reconnect automatically. However, many of our readers report situations in which the ESP8266 doesn’t reconnect.
How to reconnect ESP8266 NodeMCU after losing connection?
Alternatively, you can also try to restart the ESP8266 with ESP.restart () when the connection is lost. You can add something like the snippet below to the loop () that checks once in a while if the board is connected and tries to reconnect if it has lost the connection.
What does onwificonnect ( ) do on ESP8266?
The onWifiConnect () function simply prints that the ESP8266 connected to Wi-fi successfully and prints its local IP address. However, you can modify the function to do any other task (like light up an LED to indicate that it is successfully connected to the network).
