Arduino-ESP32 Zigbee Networks Scan Example

This example shows how to scan Zigbee Networks.

Supported Targets

Currently, this example supports the following targets.

Supported Targets ESP32-C6 ESP32-H2

Nr | PAN ID | CH | Permit Joining | Router Capacity | End Device Capacity | Extended PAN ID
 1 | 0xe6f0 | 14 | Yes            | Yes             | Yes                 | f0:f5:bd:ff:fe:02:3f:24
 2 | 0xa9bb | 24 | No             | Yes             | Yes                 | 60:55:f9:00:00:f7:52:d0

Hardware Required

  • One development board (ESP32-H2 or ESP32-C6) acting as Zigbee coordinator (loaded with Zigbee_Thermostat example)
  • A USB cable for power supply and programming
  • Choose another board (ESP32-H2 or ESP32-C6) as Zigbee end device (loaded with Zigbee_Temperature_Sensor example)

Configure the Project

In this example, the internal temperature sensor task is reading the chip temperature. Set the Button Switch GPIO by changing the GPIO_INPUT_IO_TOGGLE_SWITCH definition. By default, it's the GPIO_NUM_9 (BOOT button on ESP32-C6 and ESP32-H2).

Using Arduino IDE

To get more information about the Espressif boards see Espressif Development Kits.

  • Before Compile/Verify, select the correct board: Tools -> Board.
  • Select the End device Zigbee mode: Tools -> Zigbee mode: Zigbee ED (end device)
  • Select Partition Scheme for Zigbee: Tools -> Partition Scheme: Zigbee 4MB with spiffs
  • Select the COM port: Tools -> Port: xxx where the xxx is the detected COM port.
  • Optional: Set debug level to verbose to see all logs from Zigbee stack: Tools -> Core Debug Level: Verbose.

Troubleshooting

Important: Make sure you are using a good quality USB cable and that you have a reliable power source

  • LED not blinking: Check the wiring connection and the IO selection.
  • Programming Fail: If the programming/flash procedure fails, try reducing the serial connection speed.
  • COM port not detected: Check the USB cable and the USB to Serial driver installation.

If the error persists, you can ask for help at the official ESP32 forum or see Contribute.
