Description of problem:

I used the SMTP/Send_Text.ino in order to test this library and it fails to work.

I got this log every time (ckpt_session, ckpt_recipient and ckpt_connect are just print I placed here) :

Additional information and things you've tried:

I thought it was du to a miss configuration of mine. So, I checked everything ten times and I cannot find anything in Gmail that I miss (I followed your instructions and other sources as this one : https://randomnerdtutorials.com/esp32-send-email-smtp-server-arduino-ide/).

I also used all 2.0.X version of this GitHub project but all of them have the same issue.
I have the unpleasant impression that I miss something but since I spent the most part of the day on this without finding anything I'm asking here if something is wrong with the library ? :/

Thanks !

This is not library issue unless you config to use or enable PSRAM in Arduino IDE as your device does not have any PSRAM connected as this debug error shown.

18:20:42.619 -> E (116) psram: PSRAM ID read error: 0xffffffff
18:20:42.619 -> [W][esp32-hal-psram.c:30] psramInit(): PSRAM init failed!

[mobizt]

When you enable the PSRAM in IDE for the device that does not have PSRAM, the ESP32 core library enabled the PSRAM APIs and this library checked the PSRAM availability from core API and it failed to access the PSRAM and unexpected behavior will happen.

Yes, you nailed it ;).
I thought it wouldn't be load for this board. Thanks for your help and this great library :)
