Wifi not working with micropython 1.19.1 esp32 S3 generic spiram

It seems to freeze when the wifi station starts connecting (not sure if it's wifi, it's just the last trace of activity I have on my app). Micropython 1.18 also has the same problem.

I recompiled micropython 1.19.1 with esp-idf 4.4.1, it fixes the problem and the wifi connection works.

Esp-idf 4.4.1 works perfectly fine on esp32cam, esp32 generic, esp32 spiram and also esp32 s3 spiram, I haven't tested on esp8266.

Assessment

S Sonnet · high

Both are ESP32 WiFi bugs tied to ESP-IDF version compatibility, but they differ in symptoms, hardware, and versions. #6151 reports a specific error code (0x3014) during disconnect event handling on ESP-IDF v3.x. #8779 reports a system freeze during WiFi station connection initiation on ESP32 S3 SPIRAM with MicroPython 1.18/1.19.1, resolved by switching to ESP-IDF 4.4.1. Different error modes, different hardware targets, different ESP-IDF versions — they share the root theme of ESP-IDF version sensitivity in the WiFi subsystem but are not the same bug.

Suggested action

No closure action needed. Both issues can remain open independently. If #6151 is still present on ESP-IDF v4.x or v5.x, a comment linking to #8779 as a related ESP-IDF compatibility issue may provide useful context.
