Hi,
actually I have not time to set up and example. Is it possible to have by your side a IoTHUB and a pair of certificate to autenticate?
If yes, i will rearrange to create an example with your iothub in a couple of days.

Thanks

Not possible. I will prepare an example more in detail in a few days. Trust me It' more easy than you expected. It is just an HTTPS client, and I know for sure that the input fragment coming from the server are 16k.

Hi,
I'm using ESP-IDF v4.2-dev-1206-g741960d5c-dirty and unfortunatly I am no able to go back and understand when the code crashes.
Is there something I can try?

Hi Guys, currently i was tring to implemente a custom HTTPs client to perform a POST. I'm facing problems with mbedTLS with dynamic memory allocation. Let me explain, if I set the MAX_FRAGMENT_LENGTH to 8k IN and 4k OUT with STATIC, the POST is corretly executed. But if I switch to dynamic a crash o...
