Thanks for the response. See the statis dump below. Note that this is esp-idf v5.3.1 with the |

Out of interest, I've also captured a statis dump from esp-idf v5.2.1 with power-save disabled (e.g. esp_wifi_set_ps set to |

Are there any more details or tests which would be helpful to resolve this issue? Do you think it's related to the access point configuration? Also, note that these issues aren't present in another project instead utilizing the ESP32-S3, so at this stage, it appears to be specific to the ESP32-C6. |

What is the expected behavior?
WiFi Station connects to an Access Point and continues operating normally without errors.
What is the actual behavior?
WiFi Station connects to an Access Point, receives an IP Address , and after a 30 seconds starts logging "wifi:m f null" continuously blocking other tasks from operating.
Steps to reproduce.
examples/wifi/getting_started/stationwith ssid + password, and upload to board.wifi:m f nullto start being printed.Debug Logs.
More Information.
I've tested various wifi configurations and versions of esp-idf to narrow down this issue and discovered
esp_wifi_set_psmay have some impact on this issue, with esp-idf <= 5.2.1 working as long asWIFI_PS_MIN_MODEMorWIFI_PS_MAX_MODEMis used.Noticeably esp-idf v5.3+ has a longer delay (30 seconds) before this issue presents allowing STA_GOT_IP to be emitted, but
esp_wifi_set_pshas no effect with all power saving modes eventually returning the samewifi:m f nullerrors.(m f null, wdt)
