LWM2M Client fails to upgrade modem firmware

RE: LWM2M Client fails to upgrade modem firmware

Hello Ronan,

yes, modem error 8 and dfu err -5 occur due to the fact that first block of the FOTA image is send twice:

Hi Markus,

Sorry looks like I had a mix up, see below the error from my original log

[00:00:49.850,433] <dbg> net_lwm2m_engine.lwm2m_write_handler: BLOCK1: total:13772 current:2304 last:0
[00:00:49.850,463] <inf> app_lwm2m_firmware: Downloaded 20%
[00:00:49.852,050] <err> dfu_target_modem_delta: send failed, modem errno 8, dfu err -5
[00:00:49.852,050] <err> app_lwm2m_firmware: dfu_target_write error, err -14

I mixed up "errno 8" and "dfu err -5", "dfu err -5" maps to DFU_INVALID_DATA and not DFU_ERROR_INTERNAL_03.

So I'm assuming DFU_INVALID_DATA is from a corrupt chunk?

Thanks for the feedback, Ronan! DFU_ERROR_INTERNAL_03, is this something you see in the modem trace?

Regards,

Markus

Hi Markus,

I tried again with no changes and it worked this morning. So I'm very confused why it failed multiple times before at the same chunk. See the working log below.

I have been working on another LWM2M ticket and was told to try to do a full erase before testing, maybe this somehow fixed it?

But anyway, would you be able to tell me what the DFU_ERROR_INTERNAL_03 error I was receiving before means? Is it a corrupted chunk error?

Regarding the DNS, iBasis does not have coverage in Ireland so I must use another SIM provider. The SIM provider I'm using does not serve a DNS server on network registration so I must define one myself.

Hello Ronan,

[quote user="RonanB96"]I am triggering the download from the Leshan Server by uploading the fota test file to "Package" Resource in the "Firmware Upgrade" Object.[/quote]

Have you adjusted the Response Timeout to >5s? This was initially the root cause for failing FOTA download during my tests. You can find the “Response Timeout” field on top of the Leshan web UI.

[quote user="RonanB96"]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[/quote]

Then I do not really understand where the custom DNS server comes in? Can you elaborate?

Regards,

Markus

Hi Markus,

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

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?

Hello Ronan,

After testing the LwM2M client application myself I can confirm that there is a FOTA issue, which might be related to mfw 1.3.0.

I have not really found a pattern yet, but I’ll cross-check this with our development department.

Could you just do me a favour and run the AT Command "AT+CGMR". It would be interesting for me to see which revision your currently have loaded on your modem. Thanks!

Regards,

Markus

Hi Markus,

I haven't tried with previous modem firmware but I have successfully used the fota_download lib for upgrading modem firmware deltas without any issues

Thanks

Ronan

Hello Ronan,

I unfortunately do not have a straight forward answer to your problem. But I’ll try to dive into it a little an see if I can find a pattern. I’ll come back to you as soon as possible.

Just a quick question, though: Did firmware updates work with the previous modem firmware?

Regards,

Markus
