This guide was prepared using

Ubuntu 13.10, 64-bit
MSPGCC
- http://sourceforge.net/projects/mspgcc/

Tip
Part of this demo runs on IoT-LAB web interface, so it's supported by other operating systems. If you don't like MSPGCC, you can use IAR Embedded Workbench

Info
In the following lines, a demo will be presented in order to test the WSN430v14 UART and radio drivers, for the implementation of OpenWSN on IoT-LAB.

title	IoT-LAB architecture

IoT-LAB permits you access its large sensor network remotely, enabling your computer to be anywhere in the world. The site-servers are deployed in each of the six sites. Their function is to receive requests of experiments thru the web interface, as well as enable the communication between your computer and the motes, thru TCP forwarding.
To access the site-server remotely, IoT-LAB uses SSH. Because of this, it's required that you configure your SSH access.
More information about IoT-LAB architecture:
- https://www.iot-lab.info/tools/
- https://www.iot-lab.info/deployment/

Configure your SSH access

Following the instructions at https://www.iot-lab.info/tutorials/configure-your-ssh-access/.

Create a new experiment

On the IoT-LAB web interface, go to "Testbed", and click "New Experiment":

Give your experiment a name, for example "bsp_uart_v14"
Click "Rennes Map" to open the map representation of the motes in the Rennes site
Info
There are motes in each of the 6 sites IoT-LAB is deployed in. We choose Rennes in this tutorial, feel free to pick another one. The only constraint is that they have to be WSN430v14 motes.
On the man, select an unused node and click "Save"
Click "Next"

Image Removed

Now that you have selected a mote, you need to upload the binary image you want the IoT-LAB to load on it.

Select the mote
Create a profile (don't need to change any settings)
Use the "Choose Files" button to browse your local file system and select the 01bsp_uartprog.ihex file you have built in the step above. It is located at openwsn/openwsn-fw/firmware/openos/projects/common/01bsp_uart_prog.ihex
Click the "Add Association" button to associate the firmware to your mote
Tip
You'll see later on that you can associate different firmware images to different motes.
Click "Submit".

Image Removed

You are now presented with the details of your experiment.

Note
You might need to refresh the page for "Success" to appear in the "Deployment" column. "Success" indicates your firmware image was successfully loaded, and is now running somewhere in Rennes, France!

Access the chosen mote

Info
IoT-LAB uses NetCat to create a TCP tunnel with the motes

"Hello, World!" should be printed in your terminal periodically.
Whenever you enter a character, the board echoes it back

Code Block
user@rennes:~$ nc wsn430-<moteID> 20000 Hello, World! openwsn openwsn Hello, World! Hello, World! c c Hello, World! Hello, World! Hello, World! iotlab iotlab

Testing the Radio

Image Removed

In this application, we will use two motes. One of them will run the TX, and the other will run the RX. Each 500ms, the TX sends a packet in the air. The RX listens to these packets and write in its serial interface the length, number, RSSI, LQI and CRC of each packet.

Load 01bsp_radio_rx_prog.ihex in a mote and 01bsp_radio_tx_prog.ihex in the other

After the firmware is selected for each mote, click "Submit"

Download openwsn-fw on server

Info
The parser script's goal is to parse the packets and show them in a way humans can read. TX transmits arbitrary bytes thru the air, and not all of them have a corresponding character in ASCII table. Without it, the printed line in the terminal cannot be read. It is located at openwsn-fw GitHub repository, so we need to clone it in the server.

Code Block
user@rennes:~$ mkdir openwsn user@rennes:~$ cd openwsn user@rennes:~/openwsn$ git clone https://github.com/openwsn-berkeley/openwsn-fw.git ... user@rennes:~/openwsn$

Compile and run the parser script `01bsp_radio_rx.py`
