IEEE802.15.4 over USB Linux kernel driver

QUICK HOWTO

Prerequisites

QuarkSE devboard is connected to Linux PC with 2 USB cables and flashed with wpanusb application.

Building Linux kernel wpanusb driver

1. Make sure you have Linux kernel headers installed

   $ ls /lib/modules/`uname -r`/build

2. Type make, below is output for the latest Ubuntu

   $ make
   make -C /lib/modules/`uname -r`/build M=$PWD
   make[1]: Entering directory '/usr/src/linux-headers-4.4.0-38-generic'
     CC [M]  /usr/local/src/ieee802154/wpanusb/wpanusb.o
     Building modules, stage 2.
     MODPOST 1 modules
     CC      /usr/local/src/ieee802154/wpanusb/wpanusb.mod.o
     LD [M]  /usr/local/src/ieee802154/wpanusb/wpanusb.ko
   make[1]: Leaving directory '/usr/src/linux-headers-4.4.0-38-generic'

Loading wpanusb

You can load driver with insmod given that all dependency are loaded, otherwise use provided modprobe.sh script

$ sudo scripts/modprobe.sh

wpan0 device should appear in the network devices list

Configuring 6lowpan address

There is a script helping to configure 6lowpan address

$ sudo scripts/lowpan.sh <last octect of IP address> <channel> <pan_id>

$ sudo scripts/lowpan.sh 2 5 && ip -6 monitor dev lowpan0

Creates lowpan0 with IP address 2001:db8::2, short address 0xbee2, pan id 0xabcd using channel 5. The monitor will show the status of routes on lowpan0

lowpan0 network device should appear and IPv6 address can be checked with

$ ip addr show dev lowpan0
59: lowpan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1280 qdisc noqueue state UNKNOWN group default qlen 1
    link/[825] 92:05:91:9b:5a:2c:34:41 brd ff:ff:ff:ff:ff:ff:ff:ff
    inet6 fe80::9005:919b:5a2c:3441/64 scope link
       valid_lft forever preferred_lft forever

There is link local IPv6 address which can be used for ping6.
