3 Commits • 2 Features
May 1, 2026May 2026: Focused on expanding Zigbee gateway capabilities and shrinking binary size to improve deployment flexibility and reliability. Key progress includes ESP32-P4 support in the gateway example with Ethernet connectivity and a Kconfig-driven RCP chip selection, along with improved update error handling. In parallel, we optimized example apps for size and dependencies, expanding the app partition to the maximum available, updating dependencies, and reconfiguring mbedTLS to reduce code size. A targeted bug fix added more failure handlers for the RCP path, increasing resilience to RCP communication issues. Overall, these changes deliver stronger hardware platform support, faster time-to-market for ESP32-P4-based gateways, improved reliability, and a smaller, more maintainable code footprint.
