Aug 1, 2025August 2025 (2025-08): Delivered critical Wi‑Fi stability improvements in espressif/esp32-wifi-lib across ESP32 variants. Implemented fixes for an incorrect HT20 state check and TWT beacon/DFS scanning issues, with changes reflected in library binaries to ensure reliability in production deployments. The work reduces erroneous HT20 behavior and mitigates beacon timeouts on DFS channels, improving overall Wi‑Fi reliability in dense environments and varied hardware. This aligns with product goals of robust connectivity, lower support incidents, and smoother user experiences in ESP32 deployments.

May 1, 2025May 2025 monthly summary for espressif/esp32-wifi-lib. Focused on stability and reliability improvements in the ESP32 Wi-Fi stack to drive higher deployment reliability and lower support frictions. Key features delivered: - Wi-Fi stability improvements and bug fixes: implemented fixes around transmission power updates on country code changes, disabled bandwidth signaling RTS by default to improve compatibility, and resolved PS state machine invalidation after enabling max BSS idle. These changes reduce misconfigurations and improve consistency across regions. - BSS idle and driver reliability: updated to pre-compiled ESP32 library versions to fix Wi-Fi driver-related bugs related to bss_max_idle, reducing connection drops and improving roaming stability. Major bugs fixed: - Addressed Wi-Fi bugs related to transmission power update behavior and BSS idle handling. Commit references: 643e8bfd44ae63f367afed3c28d77d83ba818772; 8458b90f45f494e50564dff5e5364729cf79007b. Overall impact and accomplishments: - Higher connection stability and reliability for ESP32-based deployments in varied regulatory regions and network conditions. - Fewer re-connects and roaming issues, leading to improved user experience and lower field support. - Clear alignment with ESP32 Wi-Fi driver roadmap through library updates, enabling longer maintenance windows and simpler upgrades. Technologies/skills demonstrated: - Embedded C/C++, ESP32 Wi-Fi driver debugging and optimization, library version management, and Git-based change tracing. - Performance-focused debugging and problem isolation for low-level networking components.
