WiFi Manager
That simpletest example works but its a little finicky - you need to constantly check WiFi status and have
many loops to manage connections and disconnections. For more advanced uses, we recommend using
the WiFiManager object. It will wrap the connection/status/requests loop for you - reconnecting if WiFi
drops, resetting the ESP32 if it gets into a bad state, etc.
Here's a more advanced example that shows the WiFi manager and also how to POST data with some
extra headers:
