This example demonstrates how to build a Zigbee Gateway device. It runs on a Wi-Fi SoC such as ESP32, ESP32-C3 and ESP32-S3, with an 802.15.4 SoC like ESP32-H2 running [esp_zigbee_rcp](../esp_zigbee_rcp) to provide 802.15.4 radio.
The example could also run on a single SoC which supports both Wi-Fi and Zigbee (e.g., ESP32-C6), but since there is only one RF path in ESP32-C6, which means Wi-Fi and Zigbee can't receive simultaneously, it has a significant impact on performance. Hence the two SoCs solution is recommended.
Before flash it to the board, it is recommended to erase NVRAM if user doesn't want to keep the previous examples or other projects stored info using `idf.py -p PORT erase-flash`
* After Zigbee gateway starts up, it will read MAC ieee address and Zigbee stack version number from the Zigbee rcp and start working together with Zigbee rcp via UART communication to form a Zigbee network
* More Gateway functionalities supporting Wi-Fi interaction will come later
