Change Email Message

[Lnt3gr4]

Hi, I am trying to change the content text of the email for the email I wanted to be sent but it fails on all the way I tried.

I would like to modify "text" from the line 'message.text.content = "text" in the program loop section on the press of a button. Is there a command or another way to change it during the program running ? Thanks

You can assign Arduino String, string literal, const char* or char array to all options and config that accept string included the SMTP_Message class options like this.

SMTP_Message message;

message.text.content = String("This is simple plain text message");

message.text.content = String("This is ") + "simple plain text message";

const char *msg = "This is simple plain text message";

message.text.content = msg;

char text[34] ="This is simple plain text message";

message.text.content = text;

And you also can assign the html message part with

message.html.content = "<p>some html text message</p>"

message.html.content = String("<div>my html message</div>");

Make sure you understand about the multiparts message in case you include other MIME type contents other than plain/text message.

The email app or client received this message should be able to parse these multiparts message.

You own it ! I used the ' message.text.content = String("This is simple plain text message"); ' in the Loop part on a condition loop and it works. A big Thank You ! ;)

When you change the content of SMTP_Message class, then calling MailClient.sendMail(&smtp, &message)), the message sent to mail server should be changed too, no mysterious thing that caused your received email unchanged.

You should debug your code to find what is wrong with your code.

Sorry to ask again... Do you know why, after a certain time the mail session connexion seems to be closed. So when the email is trying to send, it goes on error. Is there a way to keep the connexion up /or a way to reconnect to a new session everytime I want to send an email with the trigger ?

[mobizt]

It's depending on server to close connection, or the connection is timed out due to the internet problems.

[Lnt3gr4]

ok, then do you know the best way to be sure connection will not be timed out when email will send ? thanks for answers :)

[mobizt]

The library will close the connection if 40 seconds time out reached.

It ups on your internet connection condition.

Thanks , but the application of my project is to monitor on real-time some signals, I want to be sure that when the signal trigger, I will be able to send email to know that there is a problem with my system. So if the emails are not working due to errors, I will never know there is a problem with my system... I would like to be sure that everytime it sends signals, the email session is refreshed before sending email. Is there a command to reactive the email session (Like a re-login to Smtp) on every signal trigger I will have ?

Just call connect again when you can't send.

Please try before asking.
