OpenWSN support

The WSN430 is fully supported in OpenWSN.The OpenWSN builders build the WSN430 firmware nightly:

Support for WSN430v13b is EXPERIMENTAL. WSN430v14 is fully supported.

The WSN430 mote


The WSN430 features a MSP430 micro-controller and a radio. There are two versions of the board:

  • the WSN430 1.3b features a CC1100 radio, which communicates at 868MHz

  • the WSN430 1.4 features an IEEE802.15.4-compliant CC2420 radio, communicating in the 2.4GHz ISM frequency band

Both versions are supported by OpenWSN.




  • MSP430F1611 microcontroller (16bit, 48 kb flash, 10kB RAM)

  • CC1101 or CC2420 radio chip (depending on version)

  • TSL2550 light sensor

  • DS1722 temperature sensor

  • M25P80 external flash memory (1 MB)

  • 3,7V battery (830 mAh)

Datasheets, Schematics and Resources

Although the board is fully supported by OpenWSN, the WSN430 board is NOT developed by the OpenWSN team. Below are links to the official WSN430 documentation, as well as additional resources we find useful:

This section documents how to load firmware into the WSN430.

This guide was prepared using the following:

Many (perfectly working) alternatives exist. Some are listed in the "Alternate Tools" section below.

Connect the Hardware


Make sure to use following jumper settings:

  • On the WSN430 1.3b, put the JP5 on the "batt" position
  • On the "WSN430 JTAG adaptor" board, close the JP6 jumper

Load and Run


Before you can go on, you need to install the required tools to load and debug code in the MSP430:

$ sudo apt-get install gcc-msp430 msp430-libc msp430mcu mspdebug


If you're using the MSP430-JTAG by Olimex, it connects to your computer's parallel port. You need to allow the mpsdebug tool to access that parallel port (in our case /dev/parport1).

List the available parallel ports:

$ ls -l /dev/parport*
crw-rw---- 1 root lp 99, 0 juil. 2 09:40 /dev/parport0
crw-rw-rw- 1 root lp 99, 1 juil. 2 09:40 /dev/parport1

Grant read/write access to the parallel port your MSP430-JTAG is connected to

$ sudo chmod 666 /dev/parport1

Using the following commands, you will:

  • launch mspdebug on the parallel port
  • load and run the 01bsp_leds_prog.ihex binary image
  • load and run the test_leds_xtal.ihex binary image
 See commands...
$ sudo mspdebug -j -d /dev/parport1 pif

IoT-LAB Testbed Support

IoT-LAB is a large-scale open wireless sensor network testbed operated by the French CNRS and INRIA research institutions. It features 2728 low-power sensor motes deployed in 6 different research centers throughout France. Among these 2728 motes, over 1000 are WSN430 boards.


An IoT-LAB node consists of 3 interconnected boards:


  • The "Open Node", a WSN430 fully programmable by the user (the board closest to us in the picture above)
  • The "Gateway" the board which connects the WSN430 to the IoT-LAB infrastructure and the Internet (the larger board in the picture above)
  • The "Control Node", a second WSN430 node, not programmable by the use, but used for monitoring (the board furthest from us in the picture above)


More information about IoT-LAB at

Building for IoT-LAB

The IoT-LAB's management interface allows you to load binaries images onto the boards. These images are in the "intel-standard" format, and contain the hexadecimal representation, in ASCII characters, of each byte. This means that they can be opened by a regular text editor.

For example, the following is the 00std_uart application for the WSN430v14, in "intel-standard" format:


This file can be uploaded on IoT-LAB.

All IAR projects are already set up to generate the intel-standard version of the binary (with extension .hex) for all WSN430v13b and WSN430v14 projects.
