# Gateway Example
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-H4 running [esp_zigbee_rcp](../esp_zigbee_rcp) to provide 802.15.4 radio.
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.
## Hardware Required
* One development board with ESP32 or ESP32-S3 SoC acting as Zigbee gateway (loaded with esp_zigbee_gateway example)
* A USB cable for power supply and programming
* Three jumper wires for UART (TX, RX and GND)
* Gateway doesn't function alone. Choose ESP32-H4 as Zigbee rcp (see [esp_zigbee_rcp example](../esp_zigbee_rcp))
* **Flash** Zigbee rcp on the ESP32-H4 DevKitC first **before** connecting to Zigbee gateway
* Connect the two SoCs via UART, below is an example setup with ESP32-DevKitC and ESP32-H4-DevKitC:
