Problem about use nRF Connect SDK v1.4.99-dev to implement lwm2m on nrf52840DK

[taoyinzhou]

I want to implement lwm2m, and I use nRF Connect SDK v1.4.99-dev to compile the thread firmware. 

I am using 52840DK, here is a screenshot of my project creation

No code changes . Then select build->build zephyr zephyr .hex. and  target->connect J-Link->download zephyr zephyr .hex.

The result is the following screenshot

I also tried the other samples and the hello world and coap samples are working fine.

How can I program lwm2m and run it properly on nrf82840 DK?

Hi,

The LwM2M Client sample is a nRF9160 sample, and therefore you won't be able to get it to work with nRF52840. The sample itself connects an nRF9160 DK to an LwM2M server via LTE, and the nRF52840 doesn't have LTE, so it wouldn't be possible to use the sample as it is on the nRF52840.

Best regards,

Marte
