OpenRF Platform v2.0.0-beta.1 – ESP32-S3

OpenRF Platform v2.0.0-beta.1 – ESP32-S3

The first public beta of the new ESP32-S3 generation of OpenRF Platform.

This release ports the proven ESP8266 platform to the ESP32-S3 N16R8 architecture while preserving the existing OpenRF functionality and preparing the project for further development.

Highlights

• ESP32-S3 N16R8 support
• Dual-core architecture
• Dedicated RF processing task
• 8 MB PSRAM support
• 16 MB Flash support
• Improved RF processing performance
• Improved RF Analyzer responsiveness
• MQTT and RF processing can operate concurrently
• RAW Learn & Replay
• Universal RX Slots
• Native protocol framework
• NVKP01 Kinetic protocol support
• Home Assistant Discovery
• REST / JSON API
• OTA firmware updates
• Backup & Restore
• 433 / 868 MHz operation
• Updated web interface with CPU and memory monitoring

Architecture

The ESP32-S3 port removes the major memory and processing limitations of the original ESP8266 implementation.

RF processing is separated from the main application workload using the ESP32-S3 dual-core architecture, providing a significantly stronger foundation for future OpenRF development.

Status

This is a beta release.

The core functionality has been tested and is operational, but additional testing and refinement are expected before the first stable ESP32-S3 release.

The ESP8266 implementation remains available in the esp8266 branch and is considered feature complete.

Hardware

Current reference hardware:

• ESP32-S3 N16R8
• CC1101 RF transceiver
• 433 MHz / 868 MHz
