Zigbee FOTA with nrf52840 DK sample

[Nagajans]

I'm having 52840-DK boards 3 and installed vscode,nrfsdk v2.2.0 and v2.8.0. i want to explore how to use FOTA for zigbee. are there any sample available to make it work and explore.

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?

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.

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 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?

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