Hi jonathan , i tried other applications and it works perfectly fine with that, i have edited the code and built and flshed, i am getting the following error in my putty terminal, if u can help please suggest what is this error mean,

for the same lwm2m sample in nrf/samples/nrf9160/lwm2m

I would recommend that you test some other applications on the Icarus to se if you get he same Image not confirmed error when building for the Icarus. If that is the case then I am guessing there is a config that is not sett correctly. Like the static config : Partition Manager — nRF Connect SDK 1.9.99 documentation (nordicsemi.com)

We do have the two samples here if these are what you are referring to:
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/nrf9160/lwm2m_client/README.html#

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/nrf9160/lwm2m_carrier/README.html#

Hi Jonathan,

I will get Errors in my putty terminal like the image is not confirmed, and the LTE connection doesnt happen.

I am using NRFw1.3.1 newest version of nordic software.

I have not tested Co-AP Client till now may be i can proceed with that,

Thank you

Can you provide any insight to what goes wrong?

Any logs or errors you gett that you can share?

If you could test other samples like the coap_client then we at least know there is no HW issue.

Other details like what Modem firmware are you using and what NCS version would also be great to have to help you.
Regards,
Jonathan

Hi Jonathan LL, sorry for the late reply,

I have nrf9160dk board and the LWM2M works perfectly fine with it.

Yes i have tested with nb-iot with icarus board and it worsk.

I have not tested at-client though,

yes as i predicted it should work perfectly fine, but its not even after changing ports and pheripherals in the sample,it throws me error like image not matched and etc thats why i wanted a sample or repo where LWM2M works with icarus for coiote iot device management.

Hi,

Just some questions first.

Do you have a nrf9160DK and have you tested that it works for you with the LWM2M?

Have you tested any other applications on the Icarus board? do you get LTE/NB-IoT to connect to the Icarus?

Have you tested AT client sample?

The Icarus is a supported board, as far as i know building the application for the board should be all that is needed.
