To setup the Testbed, one can simply follow the instructions below. For a successfull measurement one should follow the instruction precisely.

Required Material for our Testbed

  • HOST PC with Ubuntu installed
  • 1x Raspberry Pi
  • 2x USB - Extension Cable
  • 1x Powerbank (optional)
  • 1x Power Supply
  • 2x CC2531 Sticks (TI)
  • 1x SD Card (16GB or more recommend)
  • 1x WLAN Stick (in this case TL-WN722N)(if connection via wlan to the network is required, cable would work as well)
  • Flash Device for example CC-Debugger

Prepare the Host

To prpeare the Host please follow the next instructions. Please enter the commandline by opening terminal or pressing CTRL+ALT+T. After that enter the following line to prepare your host system.

Please execute line by line (The console lines are in a box)


sudo apt-get install autoconf autogen
sudo apt-get install gpp
sudo apt-get install g++ 
sudo apt-get install libtool
sudo add-apt-repository ppa:chris-lea/libsodium

next things have to be done by root

sudo su
echo "deb http://ppa.launchpad.net/chris-lea/libsodium/ubuntu trusty main" >> /etc/apt/sources.list
echo "deb-src http://ppa.launchpad.net/chris-lea/libsodium/ubuntu trusty main" >> /etc/apt/sources.list
apt-get update && sudo apt-get install libsodium-dev

from here no root shell required zmq

wget https://github.com/zeromq/zeromq4-1/releases/download/v4.1.4/zeromq-4.1.4.tar.gz
tar -xvzf zeromq-4.1.4.tar.gz
cd zeromq-4.1.4
make -j 4
make check
sudo make install
sudo ldconfig

python packages

sudo apt-get install python-zmq python-dev python-qt4 libzmq3-dev python-numpy

Plot Function: Download our plot.pyc script. This is availabe here in a couple of days.

Prepare the CC2531 Stick

Before we continue with the Raspberry we have to configure the CC2531 Stick. The required firmware can be downloaded (soon) here. To install this firmware to the Stick we use the CC Debugger, which is able to communicate via the proprietary TI Connection, which is installed on the Stick. In our testenvironment we install SmartRF Programmer on a Windows PC, there are other tools and devices, that offer the installation to the CC2531 device as well, but we want to focus on the way we worked with.

The required Tool can be found here : Smart RF Programmer by TI. After the installation of this tool on the computer, the user can connect the CC2531 Stick to the Debugger. In addition to that, make sure, that the Stick is connected to a power supply as well. In our case it is connected to a powerbank. If the Stick is connected in a correct way, the light of the CC Debugger-Light turn from red to green. It should look similar to the picture in the right. Be sure the cable is placed in the right direction, otherwise it might harm the CC2531.

CC Debugger connected to CC2531

After the right connection one has to choose the right device. Usually there is only one device listed, if only one CC Stick is connected at the same time. After that you select the File, which you downloaded before. Select the Radiobutton "Erase, program and verify" and press "Perform actions" to install the firmware on the CC Stick. After that the CC Stick is ready for the usage.

Set up a Raspberry

Download an install the latest version of RASPBIAN and install it to the SD Card. Several installation guides can be found on the internet. (For example this one[1])
