# Gateway Example
|
||
|
|
|
||
|
|
(See the `README.md` file in the upper level 'examples' directory for more information about examples.)
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
## 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-H2 as Zigbee rcp (see [esp_zigbee_rcp example](../esp_zigbee_rcp))
|
||
|
|
* **Flash** Zigbee rcp on the ESP32-H2 DevKitC first **before** connecting to Zigbee gateway
|
||
|
|
* Connect the two SoCs via UART, below is an example setup with ESP32-DevKitC and ESP32-H2-DevKitC:
|
||
|
|
|
||
|
|
|
||
|
|
ESP32 pin | ESP32-H2 pin
|
||
|
|
------------- |-------------
|
||
|
|
GND | G
|
||
|
|
GPIO4 (RX) | TX
|
||
|
|
GPIO5 (TX) | RX
|
||
|
|
|
||
|
|
* TX, RX pin can be also configured by user in esp_zigbee_gateway.h
|
||
|
|
|
||
|
|
## Configure the project
|
||
|
|
|
||
|
|
Before project configuration and build, make sure to set the correct chip target using `idf.py set-target esp32` or `idf.py set-target esp32s3`
|
||
|
|
|
||
|
|
## Build and Flash
|
||
|
|
|
||
|
|
Build the project, flash it to the board, and start the monitor tool to view the serial output by running `idf.py -p PORT flash monitor`
|
||
|
|
|
||
|
|
(To exit the serial monitor, type ``Ctrl-]``.)
|
||
|
|
|
||
|
|
## Example Output
|
||
|
|
|
||
|
|
As you run the example, you will see the following log:
|
||
|
|
|
||
|
|
esp_zigbee_gateway:
|
||
|
|
I (660) ESP_ZB_GATEWAY: status: -1
|
||
|
|
I (670) ESP_ZB_GATEWAY: Zigbee stack initialized
|
||
|
|
I (680) ESP_ZB_GATEWAY: Zigbee rcp device booted
|
||
|
|
I (1280) ESP_ZB_GATEWAY: Start network formation
|
||
|
|
I (3060) ESP_ZB_GATEWAY: Formed network successfully (ieee extended address: f9:54:2d:01:a0:03:f7:84, PAN ID: 0x8651)
|
||
|
|
I (4060) ESP_ZB_GATEWAY: status: 0
|
||
|
|
I (4400) ESP_ZB_GATEWAY: Network steering started
|
||
|
|
|
||
|
|
## Gateway Functions
|
||
|
|
|
||
|
|
* 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
