Ben's notes

Configuring 6LoWPAN with an ATUSB on Fedora.

• You can find the adapter here: http://shop.sysmocom.de/products/atusb
• Linux WPAN http://wpan.cakelab.org/
• WPAN tools https://github.com/linux-wpan/wpan-tools

• Install the WPAN tools:

  dnf install wpan-tools

• Connect the ATUSB and a wpan0 network device should appear.
• If the device is not already in the DOWN state, configure it down:

  ip link set wpan0 down

• Set the channel, for example channel 15:

  iwpan phy0 set channel 0 15

  # Channels
  channel-11 	2405 MHz
  channel-12 	2410
  channel-13 	2415
  channel-14 	2420
  channel-15 	2425
  channel-16 	2430
  channel-17 	2435
  channel-18 	2440
  channel-19 	2445
  channel-20 	2450
  channel-21 	2455
  channel-22 	2460
  channel-23 	2465
  channel-24 	2470
  channel-25 	2475
  channel-26 	2480

• Configure a PAN ID:

  iwpan dev wpan0 set pan_id 0xCAFE

• Configure a short address (node 1):

  iwpan dev wpan0 set short_addr 0x0001

• Add the lowpan device and enable the interfaces:

  ip link add link wpan0 name lowpan0 type lowpan
  ip link set wpan0 up
  ip link set lowpan0 up

• On node 1, listen for node 2:

  wpan-ping -d 0x0002

• On node 2, send pings to node 1:

  # wpan-ping -a 0x0001  -s 5 -c5
  PING 0x0001 (PAN ID 0xcafe) 5 data bytes
  5 bytes from 0x0001 seq=0 time=5.3 ms
  5 bytes from 0x0001 seq=1 time=5.3 ms
  5 bytes from 0x0001 seq=2 time=5.3 ms
  5 bytes from 0x0001 seq=3 time=7.9 ms
  5 bytes from 0x0001 seq=4 time=7.2 ms
  
  --- 0x0001 ping statistics ---
  5 packets transmitted, 5 received, 0% packet loss
  rtt min/avg/max = 7.162/6.199/7.917 ms

• Configure IPv6 address on node1:

  ip addr add 2001:db8::1/64 dev lowpan0

• Configure IPv6 address on node2:

  ip addr add 2001:db8::2/64 dev lowpan0

• Ping test (node 2 to 1):

  # ping6 -c5 2001:db8::1
  PING 2001:db8::1(2001:db8::1) 56 data bytes
  64 bytes from 2001:db8::1: icmp_seq=1 ttl=64 time=14.6 ms
  64 bytes from 2001:db8::1: icmp_seq=2 ttl=64 time=16.3 ms
  64 bytes from 2001:db8::1: icmp_seq=3 ttl=64 time=17.6 ms
  64 bytes from 2001:db8::1: icmp_seq=4 ttl=64 time=16.4 ms
  64 bytes from 2001:db8::1: icmp_seq=5 ttl=64 time=15.1 ms

  rtt min/avg/max/mdev = 14.669/16.056/17.607/1.041 ms

• Configure devices down:

  ip link set lowpan0 down
  ip link set wpan0 down

• Configure channel to monitor:

  iwpan phy0 set channel 0 26

• Add monitor interface:

  iwpan phy phy0 interface add monitor%d type monitor

• Enable monitor interface:

  ip link set monitor0 up

• Dump packets with tcpdump, tshark, wireshark, …
