This mode is more computationally and energy-intensive (the ESP32 board will heat up) since the ESP32 has to simulate a full WiFi router (Soft AP). In this mode, the ESP32 is not connected to any other network and is therefore not connected to the Internet. In both cases, the ESP32 can access the Internet.ĪP (Access Point) ( WIFI_AP ): In Access Point mode, the ESP32 behaves like a WiFi network (a bit like a router): other devices can connect to it. The ESP32 can behave as a client: make requests to other devices connected to the network, or as a server: other devices connected to the network will send requests to the ESP32. If the router is connected to the Internet, then the ESP32 can access the Internet. The ESP32 behaves like a computer that is connected to our router. ![]() STATION ( WIFI_STA ) : The Station mode (STA) is used to connect the ESP32 module to a WiFi access point. ![]() The built-in WiFi.h library will allow us to use the WiFi features of the ESP32 board easily. ![]() How to connect to a WiFi network with the ESP32
