Email Sender not working Arduino uno – W5100

[erjon]

Hello, im currently having the problem with my Arduino Uno + NETWORK SHIELD W5100 that when i try to make a code which sends an email when the temperature is hot its not working and giving me this output.
Sending status:
0
2
Here is my code:
#include <Ethernet.h>
#include <SPI.h>
#include <EMailSender.h>
#include <OneWire.h>
#include <DallasTemperature.h>
#include <LiquidCrystal_I2C.h>
#include <Arduino.h>

LiquidCrystal_I2C lcd(0x27, 16, 2);

// Enter a MAC address for your controller below.
// Newer Ethernet shields have a MAC address printed on a sticker on the shield
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };

EMailSender emailSend(“apikey”, “apikey”, “email”, “smtp”, port); // these are correct

#define ONE_WIRE_BUS 2 // Pin where the DS18B20 is connected

OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);

const int testnr = 30;

void setup()
{
// Open serial communications and wait for port to open:
Serial.begin(9600);
lcd.init();
lcd.backlight();
lcd.setCursor(0, 0);
lcd.print(“PEGASUS”);
lcd.setCursor(0, 1);
lcd.print(“Measure it”);
delay(2000);
lcd.clear();

// start the Ethernet connection:
if (Ethernet.begin(mac) == 0) {
Serial.println(“Failed to configure Ethernet using DHCP”);
while(1);
}

Serial.print(“IP address “);
Serial.println(Ethernet.localIP());
lcd.init();
lcd.backlight();
lcd.setCursor(0, 0);
lcd.print(“IP-Adresse”);
lcd.setCursor(0, 1);
lcd.print(Ethernet.localIP());
delay(2000);
lcd.clear();

sensors.begin(); // Initialize DS18B20 senso

}

void loop()
{

sensors.requestTemperatures(); // Request temperature readings
float temperature = sensors.getTempCByIndex(0); // Read temperature in Celsius from first sensor

Serial.print(“Temperature: “);
Serial.print(temperature);
Serial.println(” °C”);
lcd.setCursor(0, 0);
lcd.print(“Temperature:”);
lcd.setCursor(0, 1);
lcd.print(temperature);
lcd.print((char)223);
lcd.print(“C”);
lcd.print(” | “);
lcd.print(DallasTemperature::toFahrenheit(temperature));
lcd.print(” F”);

delay(5000); // Add a delay to prevent flooding the serial monitor

// Read temperature here and check if it’s above 29°C
if (temperature > 30) {
EMailSender::EMailMessage message;
message.subject = “Temperatur”;
message.message = “Hallo, die Raum Temperatur ist sehr hoch!”;

EMailSender::Response resp = emailSend.send(“mail”, message); //my email

Serial.println(“Sending status: “);

Serial.println(resp.status);
Serial.println(resp.code);
Serial.println(resp.desc);
}
}

Hi Erjon,
witch provider do you use with Arduino UNO?
Bye Renzo

Hi Renzo,

i dont quite understand the question. If you mean Internet its Telekom.
Yesterday i tried the email sender and the temperature measuring and it worked. As soon as i added LCD Screen to it it didnt work anymore.
Could you help me there mate.

Hi Erjon,
w5500 not support TLS, so pay attention if you use It.

If It doesn’t work after add more elements probably it’s a memory problem, try to disable attachments.

Hi Renzo,

i have an W5100. I said when i use EMailsender + Temperaturmeasurement it works and it sends an email after the Temperature is over 40C but when i add LCD screen to it it gives me this error:
Sending status:
0
2
About Memory i have 20% free on both memories. its very interesting why it wouldnt work when i add lcd that doesnt affect in any way.
I hope you understood me

Hi Erjon,

Sending emails requires a significant amount of memory at the exact moment the email is sent, so having only 20% of memory free might not be sufficient.

Bye Renzo
