LWM2M Client fails to upgrade modem firmware

RonanB96

modem fw 1.3.0

ncs 1.5.0 and master

I am trying to test modem firmware upgrades using the lwm2m client sample and every time it is writing the 20% downloaded chunk, the modem throws an 

DFU_ERROR_INTERNAL_03 error. The modem firmware delta is attached

I got the same result from using NCS v1.5.0 and on master.
I added in a custom DNS server as our SIM provider doesn't serve one from the network but otherwise, the sample is unchanged

    Hello Ronan,

    my apologies for the late reply! It took me some time to analyse the issue.

    What I can see in your log is that the first block of the FOTA image is send twice:

    [00:00:22.163,879] <dbg> net_lwm2m_engine.lwm2m_write_handler: BLOCK1: total:13772 current:0 last:0
[00:00:47.148,773] <dbg> net_lwm2m_engine.lwm2m_write_handler: BLOCK1: total:13772 current:0 last:0

    This is the reason for modem errno 8 and DFU err -5.

    Otherwise I wonder what kind of server it is you are connecting to since your log still says that you are connecting to the Leshian Server?

    Hi Markus, 

    Sorry for the delay, I was off most of last week. The response to AT+CGMR was mfw_nrf9160_1.3.0.

    I am triggering the download from the Leshan Server by uploading the fota test file to "Package" Resource in the "Firmware Upgrade" Object.

    My goal is just to prove that firmware upgrades triggered by an LWM2M server are possible and the underlying SDK is mature enough for our application. The Leshan server will not be used for our application
