I have now switched to the LwM2M_client from the 1.3.1 SDK and when using Target>Download zephyr/merged.hex I am getting a strange error at the end of the build process:

 Did you re-open the project after changing SDK?
It is often also recommended to check the "Clean build directory"

Hi Didrik,

I got the LwM2M client example from SKD 1.3.1 working now as well after a "clean build directory".

I have almost finished the hardware design of our own board now. What would be needed in order to be able to use the LTE Link Monitor even with our board? Would it be enough to reserve 2 pins for RxD & TxD and use an seriell to USB converter?

[Didrik Rokhaug]

Yes, exposing two pins used as TX and RX should be enough.

I would also recommend that you expose a second UART, that can be used to take modem traces, as those are very helpful if you encounter any network related issues.

Thanks Didrik,

will provide a header for two UART connections.

I got a comment from our developer supposed to take care of the LwM2M server part. He says he could not find open source examples for servers supporting DTLS and being scalable to be used for a production server. We tried the Leshan demo server and it works fine but is obviously just a demo not for production. Do you have any suggestions where to look for a start to build a production LwM2M server with DTLS support?

[Didrik Rokhaug]

I only know of the Leshan server myself. My understanding was that it should be usable for more than just demo purposes.

You should obviously not use the demo server, but host an instance yourself. What makes your developer say that the Leshan server is not suitable for a production environment?
