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

Thanks we have already gone through the SDK17 before. But i am using SDK16.

As you mentioned that the sdk16 have bootloader project, i saw that and research about their functionality to understand the logic of that bootloader. But in that example TFTP protocol is used. In my case,  i want to use Lwm2m server with CoAP protocol. So please provide any other useful information or example so that i can move further in my project. 

Please keep in touch, so we can find out the way to resolve this trouble.

Regards
Pankaj
