IPv6 over Bluetooth Smart (Low Energy)

Cross-compilation tested on Ubuntu 14.10 with kernel 3.18. Tested routers:

  • ASUS RT-N16
  • x86_64 (Virtual Box)

Prerequisites

  • Bluetooth 4.0 USB dongle
  • trunk (CC 3.18)

Needed Modules

Kernel modules→Other Modules:

  • kmod-6lowpan
  • kmod-bluetooth
  • kmod-bluetooth_6lowpan

Kernel modules→USB support:

  • kmod-usb-core
  • kmod-usb-ohci
  • kmod-usb2

Libraries:

  • bluez-libs

Utilities:

  • bluez-utils

Example of usage

Below procedure shows how to establish a connection with Bluetooth Smart device (with IPv6 stack software) and do a ping. Note that router has to have Bluetooth Smart chip or dongle connected to USB.

Load 6LoWPAN module:

modprobe 6lowpan
modprobe bluetooth_6lowpan

Set PSM channel as 0x23 (35):

echo 35 > /sys/kernel/debug/bluetooth/6lowpan_psm

Look for available HCI devices:

hciconfig

Reset HCI device - e.g. hci0 device:

hciconfig hci0 reset

Read 00:AA:BB:XX:YY:ZZ address of bluetooth device:

hcitool lescan

Connect to the device:

echo "connect 00:AA:BB:XX:YY:ZZ 1" > /sys/kernel/debug/bluetooth/6lowpan_control

Check if connection has been established:

ifconfig

Try to ping device using its link-local address, e.g. on bt0 interface:

ping6 -I bt0 fe80::2AA:BBFF:FEXX:YYZZ
