I found it is absolutely necessary to have during a file transfer to have started the SD card via: SD.begin (pinCS_SD);
Which is normally the case but in my tests I only tried to send the file without having ever written on the SD so without having started the card…

Nevertheless, I still have problems with emailsende error codes now I have a resp.code = 235 so not 0 and suddenly I redo several tests while the emails arrive well despite the code 235!
WHAT IS THIS ERROR CODE?
THANKS

With another program on the same hardware it works correctly and I get this:

15:33:42.022 -> 250 2.1.5 Ok
15:33:42.022 -> DATA:

15:34:58.856 -> Message sent!

However, this is a copy paste of this part of the file sending code..

,
OK thanks
And do you have a list of error codes returned by email sender? (354, 2, 1, 235 and others…)
THANKS

Hello, no news?
Thank You

[Gilles]

Another little question, have you already managed to send emails from the orange.fr messaging system that I created for you?
For me there is no error message (error code =0), but no receipt of emails, a bit like there with SendGrid…
It seems to me that sometimes I see the email sent in my mailbox but it disappears almost instantaneously on its own and there is no way to find any trace of it…. I can almost believe that I dreamed!
THANKS

OK, I’ve made some progress, but it still doesn’t work.
I put :

uint16_t SMTP_PORT = 587; //the smtp port 25 don't work!
const char* smtp_server = "smtp.sendgrid.net"; // your mail address smtp server
const char* email_login = "apikey"; // your sender email address
const char* email_from = "somemailaddress@gmail.com"; // Your email address
const char* name_from = sender.c_str(); //transformation from string to const char*
const char* email_password = "sengrid's super long password string";

and especially :
string sender = “Arduino1”;
// the name of Senders that I put in Sendgrid!
suddenly emailsenders no longer sees an error but I don’t receive any email… whether with gmail or orange.fr or laposte.net senders….

I get this as a return:

20:58:25.520 -> Insecure client:0

Hello,
For information, do you have the list of error codes (with their meaning) that EmailSender can return?
example error code 354, 2, 235,1 ,…

I found the following line of code in your post:
EMailSender emailSend(“apikey”, “SG.FINTOFINTOFINTO.FINTOFINTO”, “sender.mischianti@gmail.com”, “smtp.sendgrid.net”, 25 );

can you please explain to me what some parts correspond to:
* “apikey” should be the login email…
Is this the name you gave to your sendgrid key?

* “SG.FINTOFINTOFINTO.FINTOFINTO” is the sendgrid API key.

* “sender.mischianti@gmail.com” corresponds to the sender email address.
You put the address of the sendgrid account? any one?…

* smtp.sendgrid.net is the smtp server
and finally
* 25 corresponds to the smtp port.

Currently all my different attempts to send an email via sendgrid returns me an error code = 2!
THANKS

[Gilles]

For information without really report for (at home in any case) to start the w5500 shield without Ethernet (therefore in fixed IP) it is absolutely necessary to start the clock BEFORE (via an RTC.begin(); command) the Ethernet shield otherwise the shield can only start with the presence of Ethernet!
THANKS

PS: I looked at your link:
Weather radio station with Arduino UNO/MEGA Ethernet problem with EmailSender
I will see if I can create a free send grid account.
THANKS
