PRJ - Connect WiFi

From PRJ - ESP32 Scan WiFi 同一 Tutorial。

Steps

1. WiFi.mode(WIFI_STA)

2. WiFi.begin(ssid, password)

3. 状态检查: WiFi.status()

4. 查询 ESP32 Station IP: WiFi.localIP()

Code Snippets

#include <WiFi.h>

// Replace with your network credentials (STATION)
const char* ssid = "TP-LINK_8BE7";
const char* password = "xxxxxxxx";

void initWiFi() {
  WiFi.mode(WIFI_STA);                      // 1
  WiFi.begin(ssid, password);               // 2
  Serial.print("Connecting to WiFi ..");
  while (WiFi.status() != WL_CONNECTED) {   // 3
    Serial.print('.');
    delay(1000);
  }
  Serial.println(WiFi.localIP());           // 4
}
