Thanks to all,

I’m going to release a new library version with this fix and new distribution list features.

Thanks again Renzo

I check on the web and seems there are a lot of problems with Outlook,

can you try to send the txt file directly from gmail and check in outlook?

 

Bye Renzo

[Renzo Mischianti]

Try to send the attach via classic email from gmail or similar.

I think the problem is outlook.

Hi Michael,
there is an error on index of txt file, so the mime type is not set

				fileDescriptor[0].filename = F("test.txt");
				fileDescriptor[0].url = F("/test.txt");
				fileDescriptor[1].mime = "text/plain";
				fileDescriptor[0].storageType =
						EMailSender::EMAIL_STORAGE_TYPE_SD;

I rewrite the sketch and put some example, I test It with SPIFFS and work correctly

I attach the sketch with all sampe file.

Bye Renzo

Hi Michael,

I tested now my WeMos D1 mini, and the txt attachment works correctly.

But It’s strange because if the file It’s 80byte mean that there are 80 character, so It isn’t empty.

Can you send me your code PLZ.

Bye Renzo

Hi Norbert,

If the file It’s 80byte mean the there are almost 80 characters. It’s very strange, try to change extension, like xml or similar.

Please give me a feedback.

Hi Ludophot,

String isn’t a fixed size variable, so you can’t predeterminate the size of the sctrucure, try to copy String to fixed size char

char msg[10];
string mystr = "hello";

strcpy(msg, mystr.c_str());

 

Give me a feedback..

Hi Mauro,

to remove debug message you must comment this line

#define EMAIL_SENDER_DEBUG

If you have a better think about the structure write here without problem.

 

Bye Renzo

Hi Ludophot,

yes, I think you can refer this post to create the array of element/structure

More than one pcf8574 expander

 

I think It’s quite difficult to lost packet, because E32 have 512byte of buffer and the max packet size is 58byte, and when you read the buffer you remove the messages from that, so you can grab 512/58 >= 8 messages before read the buffer.

I’m quite sure that you read the message in less than millisecs.

Hi Ludopoth,

first you can’t create a structure with pointer

struct Badge_Transmition{
const char *type=NULL;
String *message = NULL;
};

but size must be fixed

struct Badge_Transmition{
char[10] type;
char[20] message;
};

the pointer size is about 2byte, but the content is in another area.

The receive device must have the same fixed size structure.

The rest of the code seems correct.

Give me a feedback Bye Renzo.

Hi Ludophot,

you can send a structure that in C is the equivalent of an object.

For example

    struct Message {
        char type[5] = "TEMP";
        char message[8] = "Kitchen";
        byte temperature[4];
    } message;
 
    *(float*)(message.temperature) = 19.2;
 
    ResponseStatus rs = e32ttl.sendFixedMessage(0,3,4,&message, sizeof(Message));
    Serial.println(rs.getResponseDescription());

I think this is what you need.

you can find more information in this article, with a complete sender sketch and receiver.

Ebyte LoRa E32 device for Arduino, esp32 or esp8266: power saving and sending structured data Part 5

pay attention to the receive of part of the strucure, very usefully to manage different type of object.

Hi Mauro,

sorry if I response so late, but I have a lot of think to follow…

I implement multiple recipient, you can find a beta version on branch

Github

You can use like so, to sent do 3 email

    EMailSender::EMailMessage message;
    message.subject = "Soggetto";
    message.message = "Ciao come stai
io bene.
www.mischianti.org";

    const char* arrayOfEmail[] = {"mischianti@gmail.com", "smtp.mischianti@gmail.com", "renzo.mischianti@gmail.com"};
    EMailSender::Response resp = emailSend.send(arrayOfEmail, 3, message);

or to send to 2 email as principal and 1 as CC

    EMailSender::EMailMessage message;
    message.subject = "Soggetto";
    message.message = "Ciao come stai
io bene.
www.mischianti.org";

    const char* arrayOfEmail[] = {"mischianti@gmail.com", "smtp.mischianti@gmail.com", "renzo.mischianti@gmail.com"};
    EMailSender::Response resp = emailSend.send(arrayOfEmail, 2, 1, message);

or to sent first to principal one to cc and one to CCn

    EMailSender::EMailMessage message;
    message.subject = "Soggetto";
    message.message = "Ciao come stai
io bene.
www.mischianti.org";

    const char* arrayOfEmail[] = {"mischianti@gmail.com", "smtp.mischianti@gmail.com", "renzo.mischianti@gmail.com"};
    EMailSender::Response resp = emailSend.send(arrayOfEmail, 1, 1, 1, message);

Give me a feedback…

Bye Renzo

Hi Adnan,

sorry if I response only now.

You can use a char array pointer

const char* emailToSend = "renzo.mischianti@gmail.com";
EMailSender::Response resp = emailSend.send(emailToSend, message);

I think you use a String variable for myemail, change type.

Bye Renzo

[Renzo Mischianti]

I think that I undestand the problem.
In my library I try to give all the possibility, and as default the body of email si in HTML format, for example you can write a text like so

    EMailSender::EMailMessage message;
    message.subject = "Soggetto";
    message.message = "<img src='http://mischianti.org/wp-content/uploads/2020/01/logo256.jpg'/><br><br>Ciao come stai<br>io bene.<br>Login set ok;<br>This is my link <a href='mischianti.org'>Mischianti's Blog</a>";

the result is an email like this

but if you want sent a simple email in TEXT format you must specify the correct mime type, so you must write an email like so

    EMailSender::EMailMessage message;
    message.subject = "Soggetto";
    message.message = "Ciao come stai\nio bene.\nLogin set ok;";
    message.mime = MIME_TEXT_PLAIN;

 

And in TEXT format line feed and carraige return work fine.

Give me a feedback, but I think the problem is this, you can try to use text line feed with HTML format.

Bye Renzo

[Renzo Mischianti]

Hi kamranrasul,
with kind of character you use? \r \n??
You can also use HTML notation and you can obtain the same result with that.
Bye Renzo
