If you are completely new to OpenWSN, and you are using Windows, read this page first. It will walk you through all the steps to install OpenWSN and explore a number of key features.
In particular you will:
- compile and run OpenWSN in simulation mode, ping a simulated mote, and interact with it over CoAP.
- program a TelosB mote, connect it to your computer, ping it, and interact with it over CoAP.
- a computer running Windows. This page is written with Windows 7 Professional.
- optionally, two TelosB motes to play with real hardware.

At the time of writing, we are using the latest and greatest of all software. Undoubtedly, this will become outdated very fast. If you see something out of the date, take action! Send an e-mail to Tengfei Chang or Thomas Watteyne to get this page update. Thanks! |
During this tutorial, you will be installing a number of tools (python, pywin32, mingw). We recommend you install the 32-bit version of all of these tools, even you have a 64-bit machine. |
Download OpenWSN
OpenWSN is a collection of repositories hosted on GitHub. We will download and use the following:
Before you can go on, you need to install a Git client. Any client will do, but we will use tortoisegit. Once you've installed it, it will integrate nicely with your Windows explorer. |
We will download these repositories side-by-side on your desktop using Git:
You now have:
At any time you can make sure you are running the latest code by right-clicking on each folder, and choosing Git Pull....
Running a simulation
Frankly, it's a bit strange to start using OpenWSN with a simulation, since the firmware is really meant (and written) to run on real motes. But, not everyone has hardware, not always the same hardware, etc. So to make things nice and easy, we'll start by simulation. Oh, and the simulated code behaves exactly the same as the real code, so what you see now is what you'll get with real hardware.
Prepare
Before we can start running a simulation, we need to compile the firmware as a Python extension. This is all explained in the OpenSim page if you want to know what's going on.
Before you can go on, you need to install mingw , which gives you all of the build tools to build the firmware: |
Before you can go on, you need to install Python: Download Python 2.7.x from https://www.python.org/ (NOT Python 3!) At the time of writing, Python 2.7.10 was just released. It doesn't work for compiling the OpenWSN code in emulation mode, for the reasons detailed in http://comments.gmane.org/gmane.comp.python.cython.user/13394. At the time of writing, we recommend you use Python 2.7.9. Let's hope Python 2.7.11 fixes this bug. If you read this and Python 2.7.11 was already released and works, please edit this page, or leave a comment at the bottom. |
- Add the following directories to your
PATH environment variable:C:\Python27 C:\Python27\Scripts
Verify you can call python : C:\Users\Tengfei>python --version
Python 2.7.9 |
- Install
pywin32 , an extension for Windows. You will need it to interact with the TAP virtual interface - Install the Microsoft Visual C++ for Windows. You will need it to compile the yappi module which will be installed with pip at next
C:\Users\Tengfei\Desktop\openvisualizer> pip install -r requirements.txt
C:\Users\Tengfei\Desktop\coap> pip install -r requirements.txt |
Install SCons, the build environment: C:\Users\Tengfei\Desktop\openvisualizer> pip install --egg scons |
If you have any problem with the installation of SCons, try the following command pip install --index-url=http://pypi.python.org/simple --trusted-host pypi.python.org --egg scons |
|

This step compile the complete OpenWSN firmware as a Python extension module (a form of shared library) which the simulation environment can import at run-time.
The extension module is at openwsn-fw\build\python_gcc\projects\common\oos_openwsn.pyd
, no need to move it.
Simulate
You can now start a simulation. Running a simulation just means taking the usual software which runs on your computer (and call "openvisualizer"), but running it in simulation mode. That is, instead of the openvisualizer connecting to real motes, it connects to emulated mote code actually running on machine.
Before you can go on, you need to install a TAP virtual interface: |

That's it, an OpenWSN simulation is now running your computer!
As SCons on Windows can be run with scons.bat, you can launch the simulation on another window with the following command : C:\Users\Tengfei\Desktop\openvisualizer>start cmd.exe /k "scons.bat" runweb --sim Closing SCons window will kill the simulation. |
Now, open http://127.0.0.1:8080/ to see the of OpenWSN.
Open the "Topology" tab:
Set up the topology to have a chain 1-2-3, and set each PDR to 1.
Back in the "Motes" tab, select mote 0001
and click on the "Toggle" button. You just declare mote 1 to be the root of your network (the DAGroot in RPL parlance, the sink in WSN parlance, the gateway, etc).
Congratulations, you have built your first OpenWSN simulated network!
Ping a mote
By convention (i.e. this is hard-coded in the software), the IPv6 prefix of the simulated network is bbbb:/64
. This means that the IPv6 address of each mote will start with "bbbb::
". The remainder of a mote's IPv6 address is it's MAC address (or EUI-64). You can read this in the web interface (under "EUI-64").
Open a new command prompt to ping mote 2:

Interact over CoAP
CoAP is a protocol implement on each OpenWSN device, which makes it appear like a web server on the Internet.
By default, an OpenWSN mote implements a CoAP "info" resource which indicate what version of the code is running. You can test that by running the Python test script provided in the :
C:\Users\Tengfei\Desktop\openwsn-fw\openapps\cinfo
OpenWSN 1.4.1

Done. Press enter to close. |
Debugging with Wireshark
In simulation mode, the openvisualizer takes care of simulating the wireless medium. You can use Wireshark to take a peek at what goes over this simulated radio space.
Before you can go on, you need to install Wireshark 6TiSCH dissectors: |
Start Wireshark (run as administrator) on the OpenWSN
interface at address, and configure the filtering for zep
(the ZigBee encapsulation protocol).
You now see all the packets exchanged over the simulated radio environment, exciting!
You may not able to see the 6LoWPAN packet in your Wireshark, then you need to configure Wireshark to decode it. Choose one packet in your wireshark and right click to choose "Decode As".
In the prompt window, Choose 6LoWPAN protocol on the Current column.
Click "OK" to close the window and do a "Reload" or press "Ctrl+R" to reload current setting. After this operation, you will see the 6LoWPAN packets.
You also need to configure the Wireshark to tell which IPv6 prefix is the network is using. In packet detail content, right click the 6LoWPAN dissect area and choose "Protocol Perference" → "Open 6LoWPAN Perference".
Type bbbb::/64 in the Context 0 textbox to indicate the prefix is using bbbb::, and click OK to close the window. A "Reload" Operation is also required.
Here is an example pcap file of openwsn simulation network with three motes: example.
Closing the OpenVisualizer
In the command prompt from where you started the OpenVisualizer, type quit
to close it
Now with real hardware
User experience with real hardware is identical than when using the simulator. Because it is a popular platform, we will use the TelosB mote, although any other supported hardware platform can be used instead.
Connecting the boards
Before you can go on, you need to install the FTDI driver for your TelosB board |
When connecting a TelosB board, Windows assigns it a COM port. in the Device Manager:
Compiling/Loading firmware
Before you can go on, you need to install mspgcc toolchain: Download the latest version from http://sourceforge.net/projects/mspgcc/files/Windows/mingw32/. At the time of writing, mspgcc-20120406-p20120911.zip . Unzip somewhere on your computer. We recommend C:\mspgcc\mspgcc-20120406-p20120911 . - Add
C:\mspgcc\mspgcc-20120406-p20120911\bin\ to your PATH environment variable
|
The build environment allow you to build the firmware and load is on all your boards with a single command (how cool is that?):

Start a network
Once the motes are programmed, you have the exact same experience as when running a simulated network.
First, start the OpenVisualizer:

Your TelosB motes turn on their blue LED once synchronized.
You might be tempted to look for a graphical representation of the topology. Unfortunately, this is only implemented in simulation mode. Really want it? Help fix . |
Ping a mote
