@Leo2442926161 , you are trying to use a recent RCP build with a not-so-recent host build.

SPINEL_RCP_API_VERSION was incremented to 5 in openthread/openthread#7118.

I suggest updating your host side implementation to one that includes openthread/openthread#7118.

Hi Jwhui, thanks very much for you quick reply.

I am using the matter border-router with connectedhomeip/otbr:te7, how do I upgrade it?

If you want to use that particular Docker image, then you can try building an RCP image from some time before openthread/openthread#7118 was merged.

Hi Jwhui, thanks again.

it works when I used old version, but it was running a little bit odd. for example,there is an error returned when I following a demo that pairing devices to border router, do you know what's going on?

@Leo2442926161 , can you enough detail to reproduce your setup? Please include hardware, git revisions, build commands, etc.

@romacdon @lmnotran , have you run into this issue before?

Hi Jwhui, thank you so much for your help.

maybe that caused by exceptional "out/python_env/bin/chip-device-ctrl", which I post a feedback it in this link: project-chip/connectedhomeip#13857

I checked the RCP commit (ec69725) out and running it on BRD4166A, the host is running at Ubuntu 20.04 in VMware.

the commands are below:
docker run -d --name "otbr" -it --rm --network host --privileged -v /dev/ttyACM0:/dev/radio connectedhomeip/otbr:te7 --radio-url spinel+hdlc+uart:///dev/radio?uart-baudrate=115200 --backbone-interface ens33

Hi @Leo2442926161 Can you post the sequence of commands you used on otbr before dataset active -x?

I am unsure about the connection reset error you are seeing, but I was able to reproduce the NotFound error at my end, and I don't think this is a bug. I can see this happen in the case where you have created a dataset on a factory reset otbr, and have not committed this yet.

In my case I was able to reproduce the observation with the following set of commands:

factoryreset

dataset init new

dataset active -x
Error 23: NotFound

This link: https://community.silabs.com/s/article/Border-Router-Docker?language=en_US doesn't seem to have any commands related to dataset manipulation.

Hi Hemanth,

I am so sorry for reply late beacause of long holiday.

it works after the version of rcp matched otbr, thanks very much.
