Just tried and works as expected. I think used /dev/ttyACM0 while the serial port to the application processor is /dev/ttyACM1.

What I did:

west build -p always -b nrf54l15dk/nrf54l15/cpuapp nrf/samples/openthread/coprocessor/
west flash --erase

sudo docker run -it --rm --privileged --name otbr --network otbr -p 8080:80 --sysctl "net.ipv6.conf.all.disable_ipv6=0 net.ipv4.conf.all.forwarding=1 net.ipv6.conf.all.forwarding=1" --volume /dev/ttyACM1:/dev/radio nrfconnect/otbr:fbde28a --radio-url spinel+hdlc+uart:///dev/radio?uart-baudrate=1000000

Thanks for the reply.

Tried your suggestion replacing "openthread/otbr" with "nrfconnect/otbr:fbde28a" using the nrf54l15-dk with broadly similar results.

Switched the nrf54l15-dk for the nrf52840dongle and that was able to see two entries under Available Thread Networks as with "openthread/otbr".

Looks like the problem is most likely related to nrf54l15-dk support.

Note that I used the v3.0.0 toolchain and SDK to build the RCP firmware.

Hi,

You're using the openthread/otbr Docker image. I would recommend using the Nordic-specific image nrfconnect/otbr. See the Running OTBR using Docker documentation to download the compatible version of the OpenThread Border Router Docker image.
