[apollo80]

Environment

• Development Kit: https://github.com/espressif/ESP8266_RTOS_SDK
• IDF version: d3a5f99
• Development Env: [make | cmake | idf.py]
• Operating System: [Ubuntu 22.04.4 LTS]
• Power Supply: [USB]
• Module: ESP-12F

Problem Description

Hi.
I have a firmware for esp8266 implementing bridge wifi-uart. The udp protocol is used for network communication.
After load testing, an error occurs:

(15025923) wifi: err2,exceed max time value,max val is 198A5759

Expected Behavior

Stable firmware operation is required for a week.

Actual Behavior

The error occurs after several hours of operation.

(15025923) wifi: err2,exceed max time value,max val is 198A5759

Steps to repropduce

1. Download and install last ESP8266_RTOS_SDK to ${HOME}/esp/ESP8266_RTOS_SDK
2. Download wireless-klipper, branch esp8266-rtos-sdk
3. Build wireless-klipper firmware:

...$ cd wireless-klipper
...$ source ~/esp/ESP8266_RTOS_SDK/export.sh
...$ cp sdkconfig.debug sdkconfig
...$ idf.py build flash

5. Run load testing (need install python modules):

...$ cd wireless-klipper/test
...$ python3 test_net.debug.udp.py

and see log __main__.log in wireless-klipper/test directory.
