Hi Nikos,

 

The project file selection depends on whether you want to use USB CDC or UART for the communication, by default UART is used, applying ` overlay-usb-nrf-br.conf` will switch to USB (you’ll need to use the “nRF USB” port on your DK).

 

As for the Border Router itself, you can either setup a RPi, or use a Docker image provided by OpenThread community and run it on any Linux host.

 

Regards,

Robert

Thank you Robert, so the idea is to flash this https://docs.zephyrproject.org/latest/samples/net/openthread/ncp/README.html on my nrf52840-dk and then using the openthread border router implementation on a raspberry to build a OpenThread Border Router (OTBR)? If yes, do I need the overlay-usb-nrf-br.conf file or just the simple proj.conf?

Regards,
Nikos

Hi Nikos,

 

Unfortunately, we don’t have a step-by-step guide for the scenario you describe, but I can provide you with some guidelines.

 

OpenThread has a reference implementation of border router, which can be run on a Linux host under docker (OpenThread is a protocol that enables IP over 802.15.4):

https://openthread.io/guides/border-router/docker

 

The `lwm2m_client` does not support OpenThread out-of-the box, but it can be easily added, see this comment:

Hi all,

I have two nrf582540-dk modules and I would like to run the lwm2m client example of the link using the leshan server. How could I implement this using real device? How my 802.15.4 device will communicate with the server running on my PC? Is there any border router? 

I really need this. Can someone point me in the right direction?

Thank you,
Nikos
