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

    After upload the nRF stuck into the infinite loop. 

     What infinite loop?

    What project is your bootloader built on? Is it the SDK17\examples\dfu\secure_bootloader\pca10056_s140_ble?

    If so, can you please try to replicate it with the project: SDK17\examples\dfu\secure_bootloader\pca10056_s140_ble_debug? If you manage to do that, what does the RTT log say when you have programmed the bootloader + SoftDevice + Application + settings.hex?
