Hi,

Installed the docker inside EFR32, but cannot execute the following command for the RCP :

Once the docker is running, you can communicate with the RCP node via an interactive shell using this command. Check the state of the RCP node.

$ docker exec -ti otbr sh -c "sudo ot-ctl"

The result shown is as :

root@3ed9d2dbac34:/app# sudo ot-ctl
connect session failed: No such file or directory

/dev/ttyACM0:/dev/ttyACM0 and the baudrate as the device was correctly made.

And the result for :

$ sudo docker logs 3ed9d2dbac34 -f ,

the log shown is as:

.....

Docker runs on your host system, I'm not sure what you mean by "docker inside EFR32".

It sounds like `ot-daemon` is not able to communicate with your RCP. I would double check that you followed the RCP setup instructions properly in the codelab's Firmware Setup section.

Hi,

As Jonathan Hui said, it seems like you are unable to establish a connection to your EFR32.

Here are a few questions to clear up the details:

1) What EFR32 or BRDnnnn are you using?

2) Did you build your project from Simplicity Studio? If so, what GSDK/OpenThread SDK version are you using?

Please provide more details concerning your steps for setting up the EFR32 firmware and the docker image.

Sincerely,

Nitish kumar s

Sorry, Sir, I had meant "Installed the docker for EFR32MG12", and we had solved the case and successfully created the RCP, by the link provided:

Hi Sir,

1) We are using BRD4166A.

2)We had built and flashed the ot-RCP using Simplicity Studio V5.

Openthread gsdk-4.0.0.

" docker pull siliconlabsinc/openthread-border-router:gsdk-4.0.0 "

( https://hub.docker.com/layers/siliconlabsinc/openthread-border-router/gsdk-4.0.0/images/sha256-b6e96578f1c923735ccdde6a2fa6f4d47a7a488989ac7196b24e4f75b87cbaec?context=explore ).

We were able to successfully activate the RCP and the case is solved.
