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

    Hi Pankaj,

    Edvin is OoO until beginning of January so I have taken over this case.

    As I understand it you have successfully copied in place the new application in bank 1, but it is not activated (copied in place etc). Is that correct? If you are doing as the example application (examples\iot\tftp\background_dfu\main.c) and TFTP DFU module then this should work out of the box. Can you share a debug log and your code so that I can better understand?
