OpenThread: Minimal Thread Device (MTD) option is not building

[ramonhpr]

Hi guys,

I'm working in a project where I have to use the minimal thread device (MTD) from openthread and I am using the zephyr as a full thread device (FTD) and is working fine with 2 boards nrf52840 but when I set the MTD option the bellow problem appears.
I am working in a fork a solution for this problem. With my changes in CmakeList the MTD was compiled properly. But the sample app echo_client was not sending through udp to my server (which was working normally with FTD). So my solution was to bump to the newest version of openthread.

Hi @ramonhpr,
I am a Newbie working on a project where I want to use Zephyr along with openThread and I don't know how exactly to use zephyr to build an FTD device .
could you please help me with running Zephyr as an FTD on two NRF52840 DK boards.

[ramonhpr]

Sure. When I used zephyr, the FTD option was the default if you'd like to change the option, you should change that. (I used to run the command make menuconfig and search for the option MTD, but I think that now you can use the command west for that).

Since you are getting started in the zephyr I recommend you to follow the getting started.

And for openthread you can use the samples echo server and echo client.

Sorry for the late answer, I hope that I could help you.
