Description

Problem Description:

When configuring ESP32-S3 as a Wi-Fi Access Point (softAP) and connecting a specific client device (a particular smartphone), the AP successfully establishes the connection, the client obtains an IP via DHCP, and the AP appears as connected (status shows 1 station).

However, after the initial connection and the first few incoming packets (e.g., an automatic HTTP request from the client immediately after connection), the AP becomes unresponsive to all subsequent incoming traffic from this client. Ping requests time out, and attempts to access the web server fail, even though the client remains connected according to the AP's status and the client's network information.

This behavior is reproducible consistently with the problematic client device. Another client device (tested with a Quest 3 VR headset) connects and communicates with the AP without issues.

The issue is not caused by:

  • Basic sketch/code errors (minimal ESP-IDF example used)
  • Power supply issues
  • ESP32 core system freezes (FreeRTOS tasks continue to run)
  • Task starvation (Wi-Fi task priority was increased in tests)
  • High TX power
  • Incorrect Flash size or Partition Scheme
  • External 2.4GHz Wi-Fi interference (tested on different channels and locations)
  • The WebServer implementation itself (works with other clients)

Your code does not appear to be using arduino-esp32. ESP-IDF issues are handled at https://github.com/espressif/esp-idf/issues
You should turn off wifi power save if you are using the device as a server.
