Настройка сети Thread: Border Router, OTBR и проектирование mesh-топологии

Установка OTBR и создание набора данных (Ubuntu / Raspberry Pi OS)

# Install OTBR (automated script — pulls Docker image or builds from source)
curl -sL https://raw.githubusercontent.com/openthread/ot-br-posix/main/script/bootstrap   | sudo bash -s -- --no-mdns
sudo INFRA_IF_NAME=eth0 ./script/setup

# Or via Docker (recommended for reproducible builds):
docker run --sysctl "net.ipv6.conf.all.disable_ipv6=0   net.ipv4.conf.all.forwarding=1 net.ipv6.conf.all.forwarding=1"   -p 8080:80 --dns=127.0.0.1 -it openthread/otbr:latest   --radio-url spinel+hdlc+uart:///dev/ttyUSB0

# Generate a new Thread dataset via ot-ctl:
sudo ot-ctl dataset init new
sudo ot-ctl dataset channel 15          # Set channel (avoid Wi-Fi overlap)
sudo ot-ctl dataset networkname PanelCraft-Thread
sudo ot-ctl dataset commit active
sudo ot-ctl ifconfig up
sudo ot-ctl thread start

# Verify dataset:
sudo ot-ctl dataset active              # Shows full OTDS in TLV format
sudo ot-ctl state                       # Should show: leader

# Export dataset as hex (for import into other Border Routers):
sudo ot-ctl dataset active -x

Веб-интерфейс OTBR — ключевые поля

OTBR web UI accessible at: http://<border-router-ip>:80

Thread Network Configuration page shows:
  Network Name:     PanelCraft-Thread
  Extended PAN ID:  6c32fcf3fe56e68b   (random 8 bytes — unique per network)
  Network Key:      d3aba6ca7f1d8e12... (128-bit AES key — keep confidential)
  PAN ID:           0x4f2b              (16-bit, random)
  Channel:          15
  On-Mesh Prefix:   fd11:22::/64       (ULA prefix assigned by Leader)

Status page shows:
  Role:             Leader / Router / Detached
  RLOC16:           0x2000             (16-bit routing locator)
  Ext Address:      ba:c7:3a:01:...    (64-bit IEEE extended address)
  Neighbours:       3 routers, 5 end devices

Ключевые диагностические команды ot-ctl

# Network state and role
sudo ot-ctl state          # leader / router / child / detached / disabled
sudo ot-ctl channel        # Current operating channel
sudo ot-ctl panid          # 16-bit PAN ID

# Router and neighbour table
sudo ot-ctl router table   # All routers in partition: RLOC16, ext addr, link quality
sudo ot-ctl neighbor table # Direct neighbours: role, RLOC16, link margin, RSSI

# Link quality (RSSI) to specific neighbour
sudo ot-ctl neighbor linkinfo <rloc16>
# Look for: link margin >10 dBm is good; <5 dBm is marginal

# End device child table (children of this router)
sudo ot-ctl child table    # Shows: child ID, mode (SED/FED), poll interval, age

# Partition info
sudo ot-ctl partitionid    # Partition ID — should be same on all nodes
sudo ot-ctl leaderdata     # Leader RLOC, partition weight, data version

# Network topology (via OTBR REST API)
curl http://localhost:8080/api/v1/node/rloc16
curl http://localhost:8080/api/v1/topology  # Full mesh topology JSON

# Ping a Thread node by IPv6 address
sudo ot-ctl ping fd11:22::1  # Replace with node's mesh-local EID
