You're so right, damn how did I not find that on GitHub...
Anyway, thanks again. Guess we'll wait for 6.0.3.

Hey guys, I just wanna give you one last update.

I did try an HTTP endpoint instead of an HTTPS one. It is, in fact, the mbedTLS bug that MicroController linked.

The heap is completely stable now:

Code: Select all

W (24721) RTOS_FETCH_TASK: (Time #2) Hello from the fetch_task. FREE HEAP: 339964

Thanks again for the help, very much appreciated! I guess now we just wait for Espressif to release IDF 6.0.3.
