If network credentials are saved, it will try to connect to WiFi.If no network credentials are saved, it will serve the WiFi manager portal.This method call will basically take care of everything : Now we will call the autoConnect method on our WiFiManager object.

We will start our code by including the WiFiManager.h library, which will give us access to the functionalities we need to perform the WiFi management through a portal. In short, the easiest way of installing the is searching it in the Arduino IDE libraries manager. You can check the installation instructions of the library here. Naturally, the library allows for many other options and configurations, for more advanced scenarios. This portal has a nice look and feel, as we will see below, thus offering a nice out of the box solution for WiFi configuration.Īs we will see in the code section, the bare minimum example will consist in creating an object, calling a method on that object and checking the outcome of the operation, which is really simple given the whole functionality the library exposes. Once we connect to the network hosted by the ESP32, we can use a device such as a computer or a smartphone to access the portal in a web browser. It’s important to mention that the ESP32 will operate in AP mode for serving this portal, meaning that it will host its own WiFi network and we don’t need to have a previously successful connection to any Access Point. The credentials we choose are saved, meaning that the next time we run our program, the ESP32 will use those credentials to try to connect to that network. This library offers a very simple way of hosting a portal in the ESP32 that, amongst other functionalities, shows the surrounding WiFi networks and allows to configure access to them.
The tests shown below were performed on a ESP32-E FireBeetle board from DFRobot.

In this tutorial we will learn how to setup a WiFi Manager portal on our ESP32, using the Arduino core and the WiFiManager library.
