EmailSender and SMTP DATA error! SMTP Response TIMEOUT!

Sorry, I didn’t see your reply.
The debug is permanently activated but you need a PC connected to the Arduino and my Arduinos are in use on my apiary…
And in addition this error does not seem systematic..
I’ll put my dev hive back in my desktop and see if I can reproduce the problem to save the debug.
I’ll let you know.
THANKS

Of course it works now…
To be continued!
THANKS

Ok thank you, I am however wired in Ethernet, but it is true that when that does not work it is all the Arduinos at the same time which seem to have this problem!

But since I have the same program in each Arduino, I was thinking more of a software problem…

Is there a way to increase the waiting time (in case of network issues)?

THANKS

Hello, still with my problem of sending attachments with SendGrid…
Sendgrid told me to test this:
https://stackoverflow.com/questions/2730055/why-would-a-csv-attachment-appear-as-text-in-the-body
basically set content-type to:
application/octet-stream;
I found in the file line 737 this:
client.println(F(“Content-Type: Multipart/mixed; boundary=frontier”));
I tested with client.println(F(“Content-Type:application/octet-stream; boundary=frontier”));
but that didn’t change anything…
Is it here or somewhere else in your library that we can determine Content-type?

THANKS

Hello, I finally managed to reproduce the error code 235, SMTP AUTH error (502-5.5.2 Error: command not recognized)
I don’t have more information per story despite this error I do receive an email…
Do you have an idea?
THANKS

I wonder if resp.code as well as resp.desc that must be deleted between 2 calls to emailsender…is updated between 2 calls to the emailsender function?
Indeed the code 235 comes from a 1st test with laposte.net which no longer works (passage to ssl) then the 2nd test which works is done with sendgrid returns me the same error code although the email be well sent….
If I put in 1st test with sendgrid I have well resp.code =0 and not 235….

Is this an error on my part or a bug?
THANKS

EMailSender::Response resp = emailSend.send(arrayOfEmail, nb_Recipient_Mail, message); // we send the email via la poste.net

    numtest=numtest-1; // we just did one more test we decrement

  
     if (resp.code == "0") { // we have just succeeded in sending mail
       
                               returnmail = 0; // sets retourmail to 0
                               reboot = 0; //we have an internet connection so we reset reboot
                               return (returnmail); // returns the return valuemail 0
                             } // it's good we exit by returning the value 0
   

   while(nbessai > 0){ // as long as we have chosen to do a test we start again

     if (resp.code != "0"){ //start another attempt to send emails

                           delay(20000); // we wait 20 seconds before trying again during this time we do nothing....
                           testconnection(); // we test the internet connection via google
                       
               
                           if (nbtry % 2 == 0) { //to go into the loop only once out of 2 (nb even)
                                                             if (monitor == 1){Serial.println(F("send with sengrid")); }
                                                             EMailSender::Response resp = emailSend2.send(arrayOfEmail, nb_Recipient_Mail, message); // we send the email
                                                                             }
                                                        else {
                                                             if (monitor == 1){Serial.println(F("send with post"));}
                                                             EMailSender::Response resp = emailSend.send(arrayOfEmail, nb_Recipient_Mail, message); // we send the email
                                                             }
               
                           numtest = numtest-1; // we just did one more test...

I wonder if resp.code as well as resp.desc should not be reset to zero between 2 calls to emailsender… between 2 calls to the emailsender function?
Has anyone tested this?
THANKS
