Need FOTA Support in LWM2M firmware update object using block2 coap process.

Pankaj Jaswal

Hi 

We searched a lot of stuff regarding FOTA update in nRF52840DK using Lwm2m and coap protocol. But we could not get help in the right direction. We could not find any stuff or documentation (explanation) regarding BACKROUND_DFU in nRF16_SDK.

We already implemented firmware object and its instance callback with existing lwm2m client example. Now we want to update the firmware over the air using lwm2m and coap protocols. Please share any kind of stuff or example you have so that we can get out from this trouble

    Hello,

    The iot section of the nRF5 SDK is no longer supported in SDK17.0.0, because it was deprecated, so I suspect there are no good documentation for the IoT part of the SDK. I don't know why it remained in the SDK for so long, because it hasn't been updated for the last 4-5 years or so.

    I guess you have already seen the SDK\examples\iot\bootloader project. Have you tried this? My assumption is that you use it like the normal bootloader in the BLE examples, but that it runs in the bacground rather than as a separate application. I have never used any of the examples in the iot folder. Let me know if it doesn't work, and I will try to reach out for someone that worked on the IoT part of the SDK back in the days.
