Configuring Zigbee samples for other ecosystems¶
You can configure Zigbee samples in nRF Connect SDK that you program onto Nordic Semiconductor’s hardware platforms to make them work within Zigbee networks of other ecosystems, such as Amazon Alexa, IKEA TRÅDFRI, or Philips Hue. This is only possible for Zigbee networks of other ecosystems that include the Trust Center.
Zigbee samples in nRF Connect SDK use the centralized type of Zigbee network.
This type of Zigbee network is created by a Zigbee Coordinator that usually acts as the Trust Center. In this network, only the Trust Center can issue encryption keys and allow Routers and End Devices into the network. The Coordinator is usually implemented on a hub or a gateway, such as Amazon Echo.
To make Zigbee samples in nRF Connect SDK work within Zigbee networks of other ecosystems, it might be required to change Zigbee sample configuration, based on the device types you are using. The following configuration scenarios are possible:
- Connecting Nordic device to a third-party Coordinator
If you are connecting a Nordic Semiconductor’s device programmed with a Zigbee sample to a third-party Zigbee Coordinator, set the
CONFIG_ZIGBEE_CHANNEL_SELECTION_MODE_MULTIKconfig option for the Zigbee sample in nRF Connect SDK. This will allow your device to scan all channels to find the Coordinator’s Zigbee network.
- Connecting a third-party Zigbee 3.0 device to a Nordic-based Coordinator
If you are connecting a third-party Zigbee device that is compatible with Zigbee 3.0 to a Zigbee Coordinator that is programmed onto a Nordic Semiconductor’s device, no additional configuration is needed.
- Connecting a third-party Zigbee legacy device to a Nordic-based Coordinator
If you are connecting a third-party Zigbee device that is not compatible with Zigbee 3.0 to a Zigbee Coordinator that is programmed onto a Nordic Semiconductor’s device, you must enable the legacy mode on the Coordinator by calling
For the scenarios with the Nordic-based Coordinator, you can select the 802.15.4 channel on which the Coordinator will form the network by setting the
CONFIG_ZIGBEE_CHANNEL Kconfig option.
Alternatively, you can enable the
CONFIG_ZIGBEE_CHANNEL_SELECTION_MODE_MULTI Kconfig option to allow the Coordinator to use the best channel with least RF interference.
After configuring the sample for other ecosystems, programming it and turning on the device, check the sample log output to see if joining (or forming) the Zigbee network is successful.
If the following message or similar is shown, the joining was not successful:
I: Network steering was not successful (status: -1)
The connection process can fail for different reasons. The following instructions can help you troubleshoot the connection problem:
Make sure that the Coordinator node is up and running.
Make sure that the network is accepting new devices. The most immediate way to verify this is to check if the LED3 on the Zigbee Coordinator node. If the LED is on, the network is configured correctly and it is open to new nodes.
Each ecosystem can also offer its own method for checking the network configuration. For example, on the Amazon Alexa ecosystem, you can say “Alexa, find my devices”.
Make sure that the device is scanning through all channels to find the Zigbee network. For example, verify that the
CONFIG_ZIGBEE_CHANNEL_SELECTION_MODE_MULTIKconfig option is correctly set.
Check if the device is compatible with Zigbee 3.0. If it not compatible, enable the legacy mode by including a call to
