Zigbee FOTA with nrf52840 DK sample

The Zigbee R23 is in production grade now. Zigbee2MQTT is not our solution, so we cannot guarantee that some 3rd party solution will work. That is out of our scope.

I was able to get Zigbee OTA working with Zigbee2MQTT by adding an external converter. However, I’d like to understand whether the ZBOSS Zigbee stack integration in Zephyr is considered production-grade. My concern arises from the fact that I’m unable to interface Nordic’s Zephyr-based Zigbee applications with third-party tooling directly, and the Zigbee2MQTT documentation notes that ZBOSS adapter support is still experimental and not recommended for production deployments. Could you provide clarification on this?

Z2M is not something that we support directly; see this post. However, you can check out this post.

We successfully got the simple_gw sample working, but our main goal is to enable OTA firmware upgrades. We’ve now established a connection with Zigbee2MQTT using the Nordic NCP sample, but OTA updates are still not working. Please see the below image, It shows firmware id is unknown even though firmware id is available in device. Could you please guide us on how to achieve this?

In your figure, there are * character in the commands. We always called it straight NCP_SLAVE_PTY=dev/ttyACM0 ./simple_gw (not sure if this could have an effect and where the * could have come from)

We are testing the simple gateway sample program with the USB port enabled in the build. For this, we are using 64-bit Ubuntu 24.04 Linux. We have the NCP sample running on one board and the light bulb sample on another board. The NCP sample board is connected to the Linux system. However, when we run the command NCP_SLAVE_PTY=ttyACM0./simple_gw, the port does not get enabled. Please find the details below for your reference.

I’m currently trying to understand how ZBOSS NCP host handles DFU. Could you please clarify which command should be used to start the DFU process and how to send the DFU command from the NCP host?

RE: Zigbee FOTA with nrf52840 DK sample

It's only compatible with 64-bit Ubuntu 24.04 Linux. See ZBOSS NCP Host.

Is the NCP host supported only on 64-bit Ubuntu 24.04 Linux, or is there also a version available for Windows 11?

Here is the Zigbee: NCP sample for R23.

When i click this NCP sample link

I am getting the below error, page not found.

I’m trying to use the host tool for Zigbee DFU. If I flash the NCP sample on the nRF52840 Dongle and run the light switch application on the nRF52840 DK, how can I use nRF Util as the Zigbee host server to transmit a firmware binary from the PC (host tool) to the Zigbee client without storing the binary on the nRF52840 Dongle?

RE: Zigbee FOTA with nrf52840 DK sample

Amanda Hsieh — Tue, 14 Oct 2025 12:57:09 GMT

You can install nRF Util and refer to the DFU over Zigbee section for more information.

Initially, we would like to experiment using a PC tool as the Zigbee server. Is there any Zigbee PC tool available from Nordic for this purpose?

Thank you for the information. With this build configuration, I was able to successfully build the Zigbee client code without any errors. However, I’m unable to find the Zigbee server code for the nRF5 SDK. Could you please share the link to the server code if available?

Hi,

How do you enable the Zigbee FOTA? Could you refer to the activating optional extensions section?

The OTA Upgrade Server can be either a standalone third-party device or it can be instantiated on an nRF52840 DK using nRF Util’s DFU over Zigbee procedure. See Zigbee FOTA doc and this post.

sureshi — Wed, 03 Sep 2025 10:20:56 GMT

Can you please help me with procedure,how can we make the sample work for FOTA. i seen light_switch code alone has FOTA implementation. what about the server. which sample we can use as server,or we need to make any modifications? it will be great help,if you can give little more procedure of this. for example if i flash light_switch example in one nrf52840-dk board, what about other board.

Hi,

Please use NCS v2.9.0 and install Zigbee R23 add-on. You can start from the Zigbee: Light switch, which supports Zigbee FOTA for nRF52840.
