Renzo, thank you for the help and the replies of course, I ‘m the least expert in this of course, but it doesn’t seem to me that its a memory problem. It does compile and running fine always producing the same results…
But… to satisfy mine and your curiosity, I will go out and get an Arduino Mega and try it there too. No harm done in that 🙂

Starting!
IP address 192.168.1.235
ONLY ONE RECIPIENTmiltiple destination and attachments
Insecure client:0
220 SG ESMTP service ready at ismtpd0005p1
Sending status:

-The structure of static IP use some memory also.

Yes it was just a suggestion since I ‘m using static anyway.

Ok, it did compile, and it gives the same exact result Renzo…

Starting!
IP address 192.168.1.235
Sending status:
0

)

Could it be that (maybe) I have something wrong in the credentials? Is there any way to debug this?

[tpapas]

I use static IP for the project anyway, maybe we can avoid all that by doing it in static…

Would that (maybe) give me more memory?

[tpapas]

It doesn’t compile, I get an error : exit status 1
stray ‘\342’ in program

[tpapas]

-try to put inside F(“string”) the serial string

I don’t understand Renzo?!

[tpapas]

Also keep in mind that I don’t use any encoding in my email address or password or api key! They ‘re copied and pasted from the sendgrid site!

Sorry Renzo … my bad! See I told you I’m a total newbie… The problem was that my serial monitor was set at 9600 baud so it couldn’t read… I set it now at 115200 and it did write :

Starting!
IP address 192.168.1.235

Insecure client:0

Still no email sent though! So what do you see?

Renzo, thank you for the effort, yes now it compiled no problem

Sketch uses 20064 bytes (62%) of program storage space. Maximum is 32256 bytes.
Global variables use 1375 bytes (67%) of dynamic memory, leaving 673 bytes for local variables. Maximum is 2048 bytes.

But the code I sent you above, doesn’t seem to do anything! Is it missing something!? Do I need to do something? It doesn’t prompt me for anything and of course it doesn’t send the email.

[tpapas]

Thank you Renzo for the immediate reply.

I did the modification and it did compile.

I do get :

“Sketch uses 27308 bytes (84%) of program storage space. Maximum is 32256 bytes.
Global variables use 2004 bytes (97%) of dynamic memory, leaving 44 bytes for local variables. Maximum is 2048 bytes.
Low memory available, stability problems may occur. ”

from the compiler!

I run it but it does absolutely nothing… What am I missing?!

Here’s the code :

#include “Arduino.h”
#include <SPI.h>
#include <Ethernet.h>
#include <EMailSender.h>

// 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(“my sendgrid API key”, “my sendgrid login pwd”, “my sendgrid login verified email”, “smtp.sendgrid.net”, 25);

void setup()
{
// Open serial communications and wait for port to open:
Serial.begin(115200);
while (!Serial) {}

delay(2000);

Serial.println(“Starting!”);

// 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());

EMailSender::EMailMessage message;
message.subject = “High Temperature in TX Site”;
message.message = “Please check the A/C unit<br>High temperature!<br>Thank you”;

EMailSender::Response resp = emailSend.send(“my sendgrid login verified email”, message);

Serial.println(“Sending status: “);

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

void loop()
{

}
