If the email work the ethernet work, the arduino clones, usually, work like a charm,

With this information It’s very difficult to do a debug.

You must give me more information, what kind of problem do you have?

Bye Renzo

Hehehehhe, I’m moved 😛

For the recipient you can follow the instruction on the article

Send email with attachments (v2.x library): Arduino Ethernet – 1

there is an example on library

Distribution list example

and the relative forum topic

EMail distribution list – more than one recipient

If you have some trouble write here.

Hi tpasas,

you are right, i put not clear label,

<YOUR-SENDGRID-API-KEY> is the user or apikey name, by default, if i remember, is ‘apikey’,

 

YOUR-SENDGRID-PASSWD> is the key generated the long string.

 

<FROM-EMAIL> is the verified email address sender.

 

I think now is more comprehensive.

 

When i have time i write a little guide.

Bye Renzo

[Renzo Mischianti]

you must set the from (in the declaration of EMailSender) the verified email, I think It’s sufficient, I don’t remember other operation.

[Renzo Mischianti]

Yes, all credential is encoded in base64.

Hi tpapas,

Next I try to free some memory from my library or do something alternative for Arduino UNO.

Now to use SMTP you must follow this step

https://sendgrid.com/docs/for-developers/sending-email/getting-started-smtp/

and

https://sendgrid.com/docs/for-developers/sending-email/integrating-with-the-smtp-api/

First you must validate the sender email than create api key to use as login and passwd.

If you have problem, write here.

Hi tpapas,

It’s the memory usage, i need to recreate the context and try to do some trick to work with this few memory.

I think for now the better solution is to get an Arduino Mega and retry, UNO had very low stats.

But i try to keep in work your configuration when find some time.

Bye Renzo

[Renzo Mischianti]

Yes,

Try to uncomment the EMailSender debug also.

#define EMAIL_SENDER_DEBUG

With this define uncommented you must receive all the client request response.

[Renzo Mischianti]

If you copy and paste my code you must substitute the double quote because the editor change these in another character.

But do the change manually to all serial, you musto incapsulate string inside F().

 

The structure of static IP use some memory also.

 

[Renzo Mischianti]

If you rewrite

Serial.print(“IP address “);

in

Serial.print(F(“IP address “));

You free 11*1byte

Hi tpapas,

I think that is a memory problem again, try to put inside F(“string”) the serial string to free some memory, but Arduino UNO with 2k of ram It’s quite tedious.

I don’t have a w5100 shield only enc26j80 that It’s quite unusable with Arduino UNO.

Bye Renzo

[Renzo Mischianti]

Hi tpapas,

It’s strange, I test the code (without shield) but I can read the Serial output on monitor.

Try to uncomment the EMailSender debug also.

#define EMAIL_SENDER_DEBUG

I have 1.8.13 version of Arduino IDE and code execute (with error because I don’t install the shield).

Bye Renzo

[Renzo Mischianti]

Hi tpapas,

I release now a new library version, now you must change the previous operation to activate W5100 like device and comment the line

// #define ENABLE_ATTACHMENTS

so a lot of memory (no SD import and similar) become free and you can send email without problem.

Give me a feedback Renzo

 

[Renzo Mischianti]

Hi manuelpilot,

now the official library support Arduino SAMD board (WiFiNINA), you can find additional information here.

Send email with attachments: Arduino SAMD boards (WiFiNINA) – 3

Bye Renzo

[Renzo Mischianti]

I think the Arduino UNO have few memory.

The sructure used is too big.

Tomorrow I check if disable sd fix the problem.

Bye Renzo
