Raspberry Pico W & EmailSender

[Erick]

Hello. Thank you for the EmailSender library which is really useful.
I’m trying to use it on a Raspberry Pico W environment
and the ESP8266SdFat library on SPI 1.

I defined in the EMailSenderKey.h file
#define SD_CS_PIN 13 instead of #define SD_CS_PIN SS

The mail message part is ok, but not the attachment of the .CSV file
If you can help me.
Thank you.

Hi Erick,
I think you don’t enable STORAGE_SD on external storage in EMailSenderKey.h.
Please paste your EMailSenderKey.h.
Bye Renzo

[Erick]

Ican’t use SD because filename has more 8 caracters …
And SD card is on SPI1 not SPI0
It’s more easy to use SDFS for me.

Sory.

Erick

[Erick]

Yes I’m confused !
Now It’s good.

Many Thank’s Renzo.

[Erick]

Thank’s for your replay Renzo

-----------

SS pin is define in the top with , and ok to SD access.
const uint8_t SD_CS_PIN = SDCARD_SS_PIN;

[Renzo Mischianti]

Hi Erick,
you can’t remove the define in the library header

//#define SD_CS_PIN SS

If you put define it externally It survives in the external context, not in the internal of the library.

Bye Renzo

[Erick]

It’s better but another problem
Here is the SD_FAT_TYPE
// 1 for FAT16/FAT32
#define SD_FAT_TYPE 1
and Sdat library is ESP8266SdFat contained in Earle F. Philhower RP2040 package 2.7.1

Hello Renzo
After several type of tests, I arrived at something positive.
If this can be a clue for you, here is what I did to get it to work properly.

Hi Erick,
I understand the ESP8266SdFat given by Raspberry is different from the original one, so I integrate your change in the version that you can find in the master branch.

#ifndef DEFAULT_EMAIL_NETWORK_TYPE_RP2040
    #define DEFAULT_EMAIL_NETWORK_TYPE_RP2040 NETWORK_RP2040_WIFI
    #define DEFAULT_INTERNAL_ARDUINO_RP2040_STORAGE STORAGE_LITTLEFS
    #define DEFAULT_EXTERNAL_ARDUINO_RP2040_STORAGE STORAGE_SDFAT_RP2040_ESP8266
#endif

Please try it and give me feedback.
Thanks, Renzo

[Erick]

OK Many Thank’s Renzo IT’S SUPER GOOD !

Another question if I can afford Renzo:
With some provider the message is indeed sent, but not delivered.
Probably because of HELO contents.
Can it be contained in an external const char* if it’s possible ?
Thank you for all.
Erick

Hi,
you can change HELO contents with

setPublicIpDescriptor("Pippo");

[Erick]

Hi Renzo

A new problem, with a file join type csv.
When a line is longer than 1071 characters, the line is broken with a newline character.
And also a newline character is added at the end of the file. (For this it is not too annoying).

Thank you

Erick

[Erick]

Hi Renzo

i am back,
Now with RP2040 I no longer use SdFat but SDFS instead
can you add with RP2040 SDFS

#define DEFAULT_EXTERNAL_ARDUINO_RP2040_STORAGE STORAGE_SDFS

https://arduino-pico.readthedocs.io/en/latest/fs.html

Thank’s you.
Erick

[Renzo Mischianti]

Hi Erick,
Do you already try to set the SD filesystem in the external storage?
Bye Renzo
