FOTA Upgrade Server implementation

Hello Tom,

I am afraid all the documentation that I can find is the OTA Server examples' description:

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

But please note that all the information here about the bootloader and SoftDevice is not relevant, as this has changed in NCS. The relevant part is only the Zigbee OTA Upgrade Cluster (which you can find more information on in the Zigbee Cluster Specification).

Regarding the 3rd party device, I am sorry, but I can't be of much help. You need to find a Zigbee stack that can run on that device, and you need to implement the OTA Upgrade Server on that device.

Yes, I also wish there was some upgrade server in NCS, but unfortunately I have been pointed to nrfutil and the nRF5 SDK when asking our Zigbee team for this earlier. I guess that most gateways that are hosting the OTA Upgrade Server are not running on Nordic devices (like in your case).

Best regards,

Edvin

Hi Edvin,

Thank you for your response. While implementing the client side, I've become fairly familiar with the referenced web resource, but I will review again since I easily could have overlooked something.

With that said, is there any documentation that shows how to implement on a non-DK device? We will actually be using the Digi IX15 Gateway, which has an XBee 3 module. For your testing of FOTA for the light_switch exmaple, what was used as the upgrade server for testing the FOTA implementation within the light switch example code? Any information regarding implementation would be helpful.

Admittedly, I am fairly new to Zigbee communications. Should I be able to find answers in Zigbee Cluster Library documentation? Even with that said, if Nordic provided a FOTA example with the light switch example, I would expect Nordic should be able to provide some implementation information of the upgrade server.

Thanks,

Tom

Hello Thomas,

As a starting page for Zigbee FOTA, please see:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/libraries/zigbee/zigbee_fota.html#lib-zigbee-fota

Setting up the server however is not straight forward. We actually don't have any ways of setting up a DFU server on a DK in NCS. To perform the update, you need to either look into the implementation in nrfutil or the DFU server from the nRF5 SDK (Zigbee and Thread version). So the new image can be generated using NCS, but to transfer it, you need to use one of the old tools. I guess you can look at the implementation of either nrfutil on Github or the nRF5_SDK_for_Thread_and_zigbee\examples\zigbee\ota\experimental_server to see how you can transfer the image to the target.

Best regards,

Edvin
