Hi FehnrirX,
the problem is that you send onnly one file but specify 2 as filenumber on this line

  EMailSender::Attachments attachs = {2, fileDescriptor};

you must change in

  EMailSender::Attachments attachs = {1, fileDescriptor};

Hi Saillu,
if you find artifact on image, I think the problem is the file sended, because I don’t apply any type of manipulation with

fileDescriptor[0].contentTransferEncoding = "base64";

I add only header that specify that the file is in base64 to the receiver.

Can you attach the complete code?

Bye Renzo

Hi Saillu,
you can test the features on this branch of github.

you must add to filedescriptor this information

fileDescriptor[0].contentTransferEncoding = "base64";

It’s untested, give me a feedback.

Hi Saillu,
I think, to do less change as possible you can do somethimg like this.

1. Save jpg.
2. Use second core of esp32 to generate a file already encoded in base64.
3. Send email with file encoded, but i must do a change to the library

Or use esp32 for all.

If u need help, write to the forum, and share your code.

Hi Saillu,
it isn’t the wifi speed, the problem is the low power of esp8266, the encoding It’s an hard process for that processor.

If you explain what you want to do we can try to find an alternative solution.

Hi,
You must define It before the include of library.
Or inside h file.

Hi Gilles,
it’s a very specific request, and honestly I have developments and additions to libraries that I developed with a higher priority.
But if I find some time I try to develop these features.
Hi Renzo

Hi Gilles,
you can try to substitute the Serial (or DEBUB_PRINT and DEBUG_PRINTLN) with a Stream of file, but you must change some code on library.

Hi RoSchmi,
don’t worry, I’m happy to hear you. I write a simple interface for FTP server, I’m going to release It soon as example of the library.

Hi RoSchmi,
I have not yet tested the device with the i2c, I am completing the article with a small application that gives the status of the FTP server.
But seems a connection problem, have you tried making an i2c scanner?
I try to test as soon as possible, but this week It’s full, I do my best.

Hi RoSchmi,
It’s possible that endTransmission (where I retrieve the begin status) had no return on Wio Terminal.

Can you try if work even if the begin had no return?

You can check your wiring with the pinout diagram

[caption id="attachment_12555" align="alignnone" width="300"] Wio Terminal pinout mischianti low resolution[/caption]

the default configuration require BCM2 (SDA) and BCM3 (SCL) pinout.

Hi C,
The success alert you that the sender device send the message, but it don’t kbow if a receiver receive it.

Try with trasparent or check M0 M1.

Enable debug and retry.

Hi C,
sorry if i answer only now, but with C name your post go on SPAM and I lost It.

Your speed air rate was different from sender and receiver. I think you must fix It.

Thanks again Renzo
