This pager is under construction. To get things moving faster, contact Thomas Watteyne.

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.

What to bring?

  • a computer running Windows. This page is written with Windows 7 Professional.
  • optionally, two TelosB motes to play with real hardware.

Download OpenWSN

OpenWSN is a collection of repositories hosted on GitHub. We will download and use the following:

Oops!

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.

Oops!

Before you can go on, you need to install mingw, which gives you all of the build tools to build the firmware:

  • Download from http://www.mingw.org/
  • Install at C:\MingGW\
  • Add C:\MinGW\bin to your PATH environment variable

  • Verify you can call the gcc command:

    C:\Users\Thomas>gcc --version
gcc (GCC) 4.8.1

Oops!

Before you can go on, you need to install Python:

  • Download Python 2.7.x from https://www.python.org/(NOT Python 3!)
  • Add the following directories to your PATH environment variable:
    • C:\Python27
    • C:\Python27\Scripts

  • Verify you can call python:

    C:\Users\Thomas>python --version
Python 2.7.5
  • Install the Python setuptools from https://pypi.python.org/pypi/setuptools#installation-instructions. Typically, this means downloading a file called ez_setup.py and double-clicking on it.

  • Verify that you can call the easy_install command:

    C:\Users\Thomas>easy_install --version
setuptools 1.1.6

  • Install the pip utility:

    C:\Users\Thomas>>easy_install pip

  • Verify that you can call the pip command:

    C:\Users\Thomas>pip --version
pip 1.4.1 from c:\python27\lib\site-packages\pip-1.4.1-py2.7.egg (python 2.7)

  • Install the OpenWSN Python dependencies (from the openwsn-sw\ directory on your Desktop):

    C:\Users\Thomas\Desktop\openwsn-sw> pip install -r requirements.pip

  • Install SCons the build environment:
     

    C:\Users\Thomas\Desktop\openwsn-sw> pip install scons
