Wio LTE EU http post

Hi

I’m Trying to post data using my WIO LTE CAT1 EU to a database, but i’m struggling with this board. I plug in 4G SIMCARD, and try a lot of sketches of http post, but without suscess. With other boards like ESP32 or ESP8266 i can make it work, but not with this one. Could anyone share a sketch example that works with this board do post or get data data? Thanks

I think you have to perform this rask by using WioLTE, wire.h and arduinohttpclient.h

Hi. I write a sketch and can obtais response from server, however it do not post anything. What could be wrong?

     char data[256];
    int status;

    SerialUSB.println("### Post.");
    sprintf(data, "api_key=%s&sensor=%s&ambiente=%.2f&interior=%.2f&voltagem=%.2f&amperagem=%.2f&potencia=%.2f", apiKeyValue.c_str(), sensor.c_str(), temp_ambiente, temp_interior, voltage, current, power);

    SerialUSB.print("Post:");
    SerialUSB.print(data);
    SerialUSB.println("");
    if (!Wio.HttpPost(URL, data, &status)) {
        SerialUSB.println("### ERROR! HttpPost ###");
    }
else
    {
    SerialUSB.print("Status: ");
    SerialUSB.println(status);
    }

The code below work on an esp32 withe httpclient.h library, that unfortunally is not compatible with Wio LTE

HTTPClient http;
    
    // Your Domain name with URL path or IP address with path
    http.begin(serverName);
    
    // Specify content-type header
    http.addHeader("Content-Type", "application/x-www-form-urlencoded");
    
    // Prepare your HTTP POST request data
    String httpRequestData = "api_key=" + apiKeyValue + "&sensor=" + WiFi.macAddress()
                          + "&location=" + "" + "&atual=" + temp_atual
                          + "&minima=" + servidor_min + "&maxima=" + servidor_max + "";
    Serial.print("httpRequestData: ");
    Serial.println(httpRequestData);
    

  // Send HTTP POST request
    int httpResponseCode = http.POST(httpRequestData);
      if (httpResponseCode>0) {
      Serial.print("HTTP Response code: ");
      Serial.println(httpResponseCode);
    }
    else {
      Serial.print("Error code: ");
      Serial.println(httpResponseCode);
    }
    // Free resources
    http.end();
