Can you share the log of that scenario as well?

Kind regards,

Unfortunately I've already tried using http:// without any success, Any other suggestions that may be worthwhile to look into ?

Kind regards,

Hassan

Try to push http:// instead of https:// first, to see if this works better.

The reason for getting an error is highly likely because you do not have the root CA for that specific domain.

Kind regards,

Håkon

Hi Håkon

I've attempted to do this by pulling an update from our own server. This is the error I'm getting.

Hi Hassan,

As stated in the former link, this is not a recommended method by leshan either.

It is recommended that you provide an URI to the object.

Kind regards,

RE: FOTA - THINGY91 lwm2m Leshan Demo Server

Hi Håkon

Thank you for your assistance. Is this "package" method a feature I can expect to work in future updates or would it be worthwhile to build with the assumption that a "Package URI" method will only be available.

Kind regards,

Hassan

RE: FOTA - THINGY91 lwm2m Leshan Demo Server

Håkon Alseth — Tue, 07 Mar 2023 15:33:32 GMT

Hi Hassan,

I wasn't able to use the "package" properly, but I did find this in the leshan wiki:

https://github.com/eclipse/leshan/wiki/Using-CoAP-Block-Wise-to-transfer-large-file-%3F

I would recommend that you try to push an URI instead.

Kind regards,

Håkon

RE: FOTA - THINGY91 lwm2m Leshan Demo Server

Hkhan7861 — Tue, 07 Mar 2023 13:47:24 GMT

Hi Håkon

I write to the package and not the package URI. I use the "\build\zephyr\app_update.bin" file saved within my project. This is where I get the "cannot find block context" error.

Kind regards,

Hassan

RE: FOTA - THINGY91 lwm2m Leshan Demo Server

Håkon Alseth — Tue, 07 Mar 2023 13:39:30 GMT

Can you share how you push the update?

Do you write to the "Package URI"?

Here's the URI that I write (http) and this is pushed to the device.

Here's the log:

I am currently using v3.2.99-ncs2-rc1. The error is thrown before the download takes place.

I have made the stock lwm2m_sample with my NBIOT settings and this is what ive found. Apologies for the late reply.

Håkon Alseth — Tue, 28 Feb 2023 18:14:47 GMT

Could you share your full log?

It looks like that error is thrown after the application image has been downloaded, is that correct?

[quote user=""]I have recently updated my toolchain and now I seem to be have having trouble with FOTA updates over lwm2m using the lwm2m client and over NBIOT. [/quote]

From which ncs version did you upgrade from? Have you tried to replicate this issue in the stock lwm2m_client sample?

Kind regards,

Håkon
