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 Edvin,

    We are facing issue while we upload the IoT_bootloader with application into our nRF52840DK. After upload the nRF stuck into the infinite loop. 

    Actually we are replacing the TFTP DFU layer to COAP DFU layer in our code. Upload the settings.hex file which we creating by using nrfutil command. And upload the softdevice + IoT_Bootloader + Application(LWM2M client code). 

    When We run this without IoT_bootloader the whole application is working fine.

    But when we merged the IoT_bootloader it is stuck always or Application code not started.
