Hi @tcpipchip

This seems to be a continuation of content from this thread, am I correct?

http://forum.espruino.com/conversations/323658/?offset=50#comment14901112

See #64 in above thread, for Gordon's succinct position with ESP32 on this matter.

While @gfwilliams is focusing his skill set on Authentic Espruino boards, and his time is valuable, others might be able to assist. It would be nice to know the environment and available memory. Please post the results of process.memory() and process.env for others to garner detail in your setup.

Yes, i was on wrong topic, sorry!

I will post that values before to run the script that call routine with certificates

Sorry again! I have to make that work to put to in my AWS IOT book with ALEXA

Let me know if runs in your ESP32

Confirming: Is the amount of free mem that after the entire upload of source code?

"free": 2155, "usage": 145

The usage seems to suggest that no certificate code has been uploaded?

@robin the certificates end up in flash memory so won't use RAM.

You could try confirming that the certificates really are the same as you put in... eg:

oca == atob("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")

But as a start, since you have the RAM on ESP32, maybe ignore all the flash storage stuff for now. Just remove fwrite and set the variables directly to the result of running atob.

... also use the certificates that I used in the example rather than making your own - for now.
