What Station Mode Is

When your board joins an existing network like a phone joins WiFi, that is Station mode. Your router is the host; the ESP is a guest. 📶

Include the Library

Everything starts by including the WiFi library. That one line gives you connect, status, and address functions.

#include <WiFi.h>

Store Your Credentials

Save your network name and password in const char variables. Keeping them near the top makes them easy to update later.

const char* ssid = "MyNetwork";
const char* password = "secret123";

SSID Is the Network Name

The SSID is simply the WiFi name you tap on your phone. It must match exactly, including capital letters and spaces.

Set the Mode

Tell the chip to act as a client with WiFi.mode(). Setting station mode keeps it from accidentally becoming its own hotspot.

WiFi.mode(WIFI_STA);

Start the Connection

Kick things off with WiFi.begin(), passing your ssid and password. This starts the handshake with the router.

WiFi.begin(ssid, password);

Connecting Takes Time

Joining is not instant. You wait in a loop and check WiFi.status() until it reports WL_CONNECTED.

while (WiFi.status() != WL_CONNECTED) {
  delay(500);
  Serial.print(".");
}

Show Progress Dots

Printing a dot each loop gives friendly feedback. When the dots stop, your board has successfully joined the network.

Grab Your IP Address

Once connected, the router hands your board an IP address. Read it with WiFi.localIP() so you know how to reach the device.

Serial.println(WiFi.localIP());

The IP Identifies the Device

That IP address is your board's home on the network. You type it in a browser later to open pages your ESP serves.

When It Will Not Connect

Stuck on dots forever? Double-check the password and SSID, and remember ESP boards only join 2.4 GHz networks, not 5 GHz.

Quick Check

After WiFi.begin runs, how do you confirm the board actually joined the network?

Recap

You joined a router in Station mode: include WiFi, set credentials, call begin, wait for WL_CONNECTED, then print your IP. 🎉
