Hi jetronic,
under my roof I have only the power from solar inverter, so if no sun no power, and I add an UPS to the device so the server It’s always online, and I prevent power noise.

The system work without that also, you must only remove the battery shield.

Hi Gilles,
sending email need a good quantity of ram, so if you have a memory leack in some part of your code, It’s possible that when EMailSender request It’s quote of memory the microcontroller reboot.

A good practique is to separate all the functionality in function with a specified scope, so qhen function finish you free all memory.

Hi,
you can refer this article to learn all the constructors

Ebyte LoRa E32 device for Arduino, esp32 or esp8266: library – Part 2

The second constructor is what you need. SoftwareSerial is not needed for esp32.

LoRa_E32(byte txE32pin, byte rxE32pin, HardwareSerial* serial, UART_BPS_RATE bpsRate = UART_BPS_RATE_9600, uint32_t serialConfig = SERIAL_8N1);
LoRa_E32(byte txE32pin, byte rxE32pin, HardwareSerial* serial, byte auxPin, UART_BPS_RATE bpsRate = UART_BPS_RATE_9600, uint32_t serialConfig = SERIAL_8N1);
LoRa_E32(byte txE32pin, byte rxE32pin, HardwareSerial* serial, byte auxPin, byte m0Pin, byte m1Pin, UART_BPS_RATE bpsRate = UART_BPS_RATE_9600, uint32_t serialConfig = SERIAL_8N1);
Breaking change on esp32 constructor

Hi Sailorman,
thanks to you for your feedback, I’m going to incorporate the features, so other can use It.
If you want write an article about your project we are happy to publish It.

Hi Asmi,
you select Arduino conf for esp32.

Please check the tutorial.

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

[Renzo Mischianti]

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.

Bye Renzo

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.

[Renzo Mischianti]

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

[Renzo Mischianti]

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.

Attachments:

You must be logged in to view attached files.

[Renzo Mischianti]

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.

Bye Renzo
