=====Fedora - 802.15.4 ATUSB=====
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]]

====Configure the adapter====
  * Install the WPAN tools:<code>dnf install wpan-tools</code>
  * Connect the ATUSB and a ''wpan0'' network device should appear.
  * If the device is not already in the DOWN state, configure it down: <code>ip link set wpan0 down</code>
  * Set the channel, for example channel 15:<code>iwpan phy0 set channel 0 15</code><code>
# 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-22 	2460
channel-23 	2465
channel-24 	2470
channel-25 	2475
channel-26 	2480
</code>
  * Configure a PAN ID:<code>iwpan dev wpan0 set pan_id 0xCAFE</code>
  * Configure a short address (node 1):<code>iwpan dev wpan0 set short_addr 0x0001</code>
  * Add the lowpan device and enable the interfaces:<code>ip link add link wpan0 name lowpan0 type lowpan
ip link set wpan0 up
ip link set lowpan0 up</code>
====Test WPAN layer====
  * On node 1, listen for node 2:<code>wpan-ping -d 0x0002</code>
  * On node 2, send pings to node 1:<code># 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
</code>
====IPv6====
  * Configure IPv6 address on node1:<code>ip addr add 2001:db8::1/64 dev lowpan0</code>
  * Configure IPv6 address on node2:<code>ip addr add 2001:db8::2/64 dev lowpan0</code>
  * Ping test (node 2 to 1):<code># 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=5 ttl=64 time=15.1 ms

--- 2001:db8::1 ping statistics ---

rtt min/avg/max/mdev = 14.669/16.056/17.607/1.041 ms
</code>
====Monitor mode====
  * Configure devices down:<code>ip link set lowpan0 down
ip link set wpan0 down</code>
  * Configure channel to monitor:<code>iwpan phy0 set channel 0 26</code>
  * Add monitor interface:<code>iwpan phy phy0 interface add monitor%d type monitor</code>
  * Enable monitor interface:<code>ip link set monitor0 up</code>
  * Dump packets with tcpdump, tshark, wireshark, ...
