Cannot set OTBR baud rate according to instructions

[whyeye]

I am trying to follow the instructions in this section: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_thread_tools.html#installing-otbr-manually-raspberry-pi

Specifically, the part where it says to set the baud rate using the command "spinel+hdlc+uart:///dev/ttyACM0?uart-baudrate=1000000". 

On my Raspberry Pi setup, it says that the directory does not exist: -bash: spinel+hdlc+uart:///dev/ttyACM0?uart-baudrate=1000000: No such file or directory

In which directory should I be running this command?

I should note that it seems I can start a Thread network just fine without setting the baud rate to 1000000. However, I am unable to pair a Matter device, so I'm trying to troubleshoot that and suspect this might be the reason?

Hi Yi,

Just ignore this command now.

The latest https://github.com/openthread/ot-br-posix.git has already set this automatically.

Best regards,

Where is this set?

This is set in  /etc/default/otbr-agent

OTBR_AGENT_OPTS="-I wpan0 -B eth0 spinel+hdlc+uart:///dev/ttyACM0 trel://eth0"
