Help: ConBee 2 with OpenThread Border Router in Docker Won’t Start

Configuration Matter/Thread
1

Hi everyone,

I’m trying to run my ConBee 2 as an OpenThread Border Router via Docker, but I’m running into issues. After flashing with GCFFlasher, the otbr-agent fails to start properly.

What I did:

  1. Flashed ConBee 2:
GCFFlasher_internal -d /dev/ttyACM0 -t 60 -f ot-rcp-cb2_0x01010700.GCF
  1. Configured otbr-env.list:
# Adjust otbr-env.list
OT_RCP_DEVICE=spinel+hdlc+uart:///dev/ttyACM0?uart-baudrate=1000000
# IMPORTANT: Use wlp1s0 instead of wlan0/eth0
OT_INFRA_IF=wlp1s0      # Your Wi-Fi interface
OT_THREAD_IF=wpan0

# Log level
OT_LOG_LEVEL=7

# Optional WLAN optimizations
OT_BACKBONE_ROUTER=1
OT_NAT64=1
  1. Started Docker:
docker run --name=otbr --detach --network=host --cap-add=NET_ADMIN \
  --device=/dev/ttyACM0 --device=/dev/net/tun \
  --volume=/var/lib/otbr:/data --env-file=otbr-env.list \
  --restart=always openthread/border-router

Problem:

When checking the logs (docker logs otbr -f), I repeatedly get errors like:

iptables v1.8.10 (nf_tables): interface name `wlp1s0      # Dein WLAN-Interface' must be shorter than IFNAMSIZ (15)
...
P-Trel--------: Failed to bind socket to the interface wlp1s0      # De
Platform------: PrepareSocket() at trel.cpp:215: No such device
otbr-agent exited with code 5 (by signal 0)

Additionally, it seems communication with the co-processor is failing:

P-SpinelDrive-: Waiting response: key=1
P-SpinelDrive-: Wait for response timeout
Platform------: Init() at spinel_driver.cpp:87: Failure
otbr-agent exited with code 1 (by signal 0)

Questions:

  1. Could the issue be my Wi-Fi interface (OT_INFRA_IF)? I left it as in the example, including the comment.
  2. Is the co-processor reset / Spinel timeout normal after flashing, or did I flash something incorrectly?
  3. Are there known Docker settings on Linux that make otbr-agent run stable?

Any tips or guidance to get my ConBee 2 working again would be much appreciated.

Thanks in advance!

Buy a new stick is my advice.
