WhatsNext Red 開發板 義大利製 相容Arduino Uno Wifi （絕版品，可收藏）

// A) WiFiLink 測試：連 Wi-Fi 並做一次 HTTP GET
#include <WiFiLink.h>
#include <WiFiClient.h>
char ssid[] = "YOUR_SSID";
char pass[] = "YOUR_PASSWORD";
WiFiClient client;
void setup() {
 Serial.begin(115200);
 while (!Serial) {}
 Serial.println(F("Connecting WiFi (WiFiLink)..."));
 int status = WL_IDLE_STATUS;
 while (status != WL_CONNECTED) {
   status = WiFi.begin(ssid, pass);
   delay(4000);
   Serial.print('.');
 }
 Serial.println();
 Serial.print(F("IP = ")); Serial.println(WiFi.localIP());
 if (client.connect("example.org", 80)) {
   client.println(F("GET / HTTP/1.1"));
   client.println(F("Host: example.org"));
   client.println(F("Connection: close"));
   client.println();
 } else {
   Serial.println(F("HTTP connect failed"));
 }
}
void loop() {
 while (client.available()) Serial.write(client.read());
 if (!client.connected()) { client.stop(); while (1) {} }
}

// B) esp-link 測試：UNO 透過 esp-link 發 HTTP GET
#include <SoftwareSerial.h>
#include <ELClient.h>
#include <ELClientWiFi.h>
#include <ELClientSocket.h>
SoftwareSerial esp(8, 9);   // 依實接修改：UNO D8=RX, D9=TX
ELClient       el(&esp, &esp);
ELClientWiFi   wifi(&el);
ELClientSocket sock(&el);
const char* SSID = "YOUR_SSID";
const char* PASS = "YOUR_PASSWORD";
void setup() {
 Serial.begin(115200);
 esp.begin(115200);  // 與 esp-link 設定一致
 delay(1000);
 bool ok = false;
 for (int i = 0; i < 10 && !ok; i++) {
   el.Process();
   ok = wifi.setMode(ELClientWiFi::STATION) && wifi.connect(SSID, PASS);
   delay(500);
 }
 Serial.println(ok ? F("WiFi ready via esp-link") : F("WiFi connect failed"));
 sock.begin("example.org", 80);
 while (!sock.connected()) { el.Process(); delay(10); }
 sock.print("GET / HTTP/1.1\r\nHost: example.org\r\nConnection: close\r\n\r\n");
}
void loop() {
 el.Process();
 while (sock.available()) Serial.write(sock.read());
}
