Thread is an IPv6-based, low-power mesh network protocol that offers advantages such as self-organization, no single point of failure, wide coverage, and large network capacity. Espressif now provides comprehensive Thread software & hardware platform solutions, including various Thread-supporting SoCs, Thread Border Router, Matter over Thread, RainMaker over Thread, etc.

We have set up a large-scale Thread network testing platform based on Espressif's Thread platform solution and Thread SoCs (e.g., ESP32-H2, ESP32-C6, etc.) to test and verify the performance of the Thread network. This video demonstrates the networking performance with 300 Thread nodes: network formation done within 2 minutes, stable connections, and the ability to achieve point-to-point communication.
