I'm having big problems making the WiFi Power Save IDF example to work properly.
The problem is that the firmware crashes with a Panic at wakeup.
I've seen quite some posts describing the same kind of issue, most are pretty old.
Some seems to suggest that the issue was fixed, some have no answer.
I've tried various IDF versions v3.2, v3.3, v3.3-beta3, v4.0-dev all leading to the same results.
The example code has only been modified:
- to use my network credentials (I'm using a plain TP-LINK Wireless router)
- to extend the wake-up delay from 2000µs to 10000µs as suggested in some posts and docs.
I'm building the code in Visual Studio using VisualGDB ESP32 plugin (all up to date).
I'm using an ESP-WROOM-32 module on the following board:
https://www.az-delivery.de/products/esp ... oard?ls=de
The WROOM module is labeled:
Z11-161007
FCC ID:2AC7Z-ESPWROOM32
Here is the log:
Does anyone have some hints on how to proceed or solve this issue?ets Jun 8 2016 00:22:57
