The method returns a code between 0 and 6 to which corresponds a constant whose meaning here is

The WiFi.status method allows you to know the connection status at any time. The WiFi.begin() method takes two parameters which are the network ID and the password You just need to know the identifier of the WiFi network to which you want to connect the ESP32 module as well as the password. Here is an example of code that allows you to connect to the local WiFi network.īefore uploading the code, replace the Wi-Fi network identifier enter_your_ssid and the password enter_your_password in the code #include Ĭonst char* password = 'enter_your_password'

Arduino code to connect an ESP32 to the WiFi network We could for example use UDP to develop a WiFi remote control to control a drone, robotic arm, RC car. On the other hand, the data transmission is ultra-fast. UDP uses a simple “send and forget” transmission model with no guaranteed delivery, ordering, or duplicate protection. UDP is used to send and receive UDP (User Datagram Protocol) messages. Server allows to start a small web server on the ESP32 Clients are created which can access the services provided by a server in order to send, receive and process data. Exchange data between two (or more) ESP32 modules without the need for a WiFi router.Ĭlient is not a connection mode in the strict sense.To do this, I advise you instead to use the WiFiManager library which is the specialty. To develop home automation accessories or connected objects without “hard” compiling the connection parameters to the WiFi network.This is for example the mode used by ESP Easy Mega (or ESP Easy). In this mode, we create an HTML page that will allow you to enter parameters for connection to a WiFi network or whatever else you want.

This operating mode is also called a software access point (soft-AP).īe careful, in this mode the ESP32 is not connected to the internet.

This is the default mode.Īccess Point transforms the ESP32 into an access point (AP), i.e. Station Station mode (STA) is used to connect the ESP32 module to a Wi-Fi access point. The WiFi library for ESP32 offers several modes of Wi-Fi connection. Different WiFi connection modes available
