Espressif Systems is proud to announce that the ESP32-C6 has achieved the Thread 1.4 Interoperability Certification, marking a significant milestone in our commitment to providing state-of-the-art IoT solutions. Tested by the Thread Group's authorized test laboratory, the ESP32-C6 demonstrates seamless compatibility with the latest Thread 1.4 protocol, ensuring robust performance, enhanced security, and interoperability across a wide range of IoT devices. 

Key Highlights of ESP32-C6 with Thread 1.4: 

·  Secure Device Commissioning: 

The ESP32-C6 supports Thread Commissioning Over Authenticated TLS (TCAT), simplifying the deployment of Thread devices. Integrating a certificate-based TLS commissioning provides strong security for large-scale IoT device networks. 

·  Advanced Diagnostics for Network Reliability: 

Thread 1.4 introduces extended diagnostic tools that simplify troubleshooting and enable developers to collect critical diagnostic data from devices. This feature ensures reliable network operation and streamlines the management of IoT deployments. 

·  Flexible Device Roles for Energy Efficiency: 

The ESP32-C6 supports critical Thread device roles, such as Full-Thread Devices (FTD), minimal-thread devices (MED), and Sleepy-End Devices (SED). Thread 1.4 optimizes these roles, enabling ESP32-C6-based devices to be more power-efficient while maintaining robust connectivity. 

·  Enhanced Internet Connectivity with Thread over Infrastructure: 

Thread 1.4 enhances internet connectivity for devices by supporting both IPv6 and IPv4. It allows Thread devices to obtain globally routable IPv6 addresses via DHCPv6 Prefix Delegation, enabling direct communication with other IPv6-enabled services. 

The Thread SDK enabling this certification is a part of the Espressif SDK, providing developers with a comprehensive and reliable toolkit to design and deploy Thread-based solutions. 

Espressif remains committed to advancing open standards and interoperability in the IoT space. The ESP32-C6, with its cutting-edge features and Thread 1.4 certification, is poised to empower developers in building scalable, secure, and efficient IoT ecosystems.
