🛠 Zigbee 3.0 et Thread 1.3 sur le radio 802.15.4

The C6 is not just a Wi-Fi chip: its IEEE 802.15.4 radio runs Zigbee 3.0 and Thread 1.3, and the C6-MINI-1 and C6-WROOM-1 modules are certified for these stacks. Advanced tutorial: set up a mesh network. Zigbee option: start from the ESP-IDF examples examples/zigbee (light switch, gateway) or from the ESP-Zigbee-SDK; a Zigbee switch in deep-sleep at 7 µA is THE textbook case. Thread option: Thread 1.3 stacks are integrated via ESP-IDF. Since Wi-Fi, BLE, and 802.15.4 coexist on the same antenna, you can commission via BLE and then switch traffic to Thread. For a full Thread border router, you will need a second device connected to the IP network — Linux + C6 or ESP32-S3 + C6 via the esp-thread-br project; the C6 alone is not intended to be the gateway. Check the silicon revision and the official errata document before designing a product, and remember that GPIO24/25/26/28/29/30 are reserved for the SPI0/1 flash interface on QFN40 designs with external flash: your mesh pinning depends on this from the schematic stage.
