zigbee OTA server sample for ncs2.9..0

[sureshi]

Hi I'm trying to work on OTA implementation for zigbee with nrf52840-DK boards. 

there is a sample available in ncs2.9.0,light switch,but i understand it can only work as client(which receives the firmware update).

I could not find any examples or references for zigbee OTA server side examples. in many places they are suggesting to refer the link,

https://infocenter.nordicsemi.com/topic/sdk_tz_v4.2.0/zigbee_example_ota_server.html?cp=9_3_3_8_5_2_1

but it says no page found. Can some please help with this. if u have any sample please share or at least share some working links for OTA samples

Hi,

We do not have an OTA server sample in the nRF Connect SDK.
There is a sample available in the nRF5 SDK for Thread and Zigbee, but this SDK is deprecated and can not be used for certification, so I do not recommend using it. It is possible to look at the sample to see how the Zigbee OTA server is implemented there, but you would have to implement a lot yourself to get it to work in the nRF Connect SDK. This is the correct link to the sample: https://docs.nordicsemi.com/bundle/nrf5_sdk_thread_zigbee/page/zigbee_example_ota_server.html.

If you want a Zigbee OTA server for testing, you can use nRF Util and an nRF52840 DK, see DFU over Zigbee. If you build a sample with Zigbee FOTA enabled in the nRF Connect SDK, the Zigbee-specific image is automatically generated in the build folder, so you do not need to use the command to generate it manually. So, you only need to use this command:

nrfutil nrf5sdk-tools dfu zigbee -f <ota_image> -chan <channel> -snr <ota_server_serial_number>

Best regards,
Marte

We’re facing challenges implementing the OTA server using the link you provided. Could you please suggest a way to modify the NCS client code to function as a server—perhaps through documentation or an example file similar to fota_server.c from the nRF5 SDK?
