New web terminal available on the testbed webportal and websocket CLI tools

19 Mar 2019

We would like to inform you about new features available that simplify the access to the serial port of FIT IoT-LAB nodes.

Direct access via the testbed webportal

It is now possible to access the serial port of all nodes but the A8 from the experiment details page on the testbed webportal.
Each node in an experiment now provides a terminal icon in the list of supported actions: just click on it and a web terminal pops up with direct access to the serial port of the node.

This makes the user experience as simple as possible when using FIT IoT-LAB via the testbed webportal!

There are things to take into account though:

  • The access to the serial port is similar to the netcat access on port 20000 from the SSH frontends: only one TCP connection at a time is possible. This means that you cannot use the web terminal if a TCP connection is already opened using netcat. And vice-versa.
  • The serial stream transport uses a websocket connection between the browser and the FIT IoT-LAB web server. For performance reasons, only 2 websocket connections on a single node are allowed at a time and 10 websocket connections per site per user in total are allowed.

This new feature is used in The first experiment for beginners in video of the Learn page.

New websocket CLI Tools

The access to the node serial port via websockets also makes it possible to aggregate serial input/output of nodes from different sites on a single computer. To do this, we released a new CLI tool: the ws-cli-tools.
It is open source, compatible with Python 2 and Python 3 and available on PyPI.

See the Websocket client documentation to learn how to install and use it with the FIT IoT-LAB testbed.

Deployement of Le Cube on Lille site

10 Jan 2019

We are very happy to announce the release of a new location for experimentation boards on the Lille site of IoT-LAB.

We’ve added Le Cube, a space for heterogeneous interoperability & compatibility

For now, we’ve deployed boards that are capable of 802.15.4 in both 2.4 GHz and sub-GHz, boards using BLE, and boards using LoRa. They all coexist in a small vicinity:

  • 5 Iot-LAB M3 boards
  • 5 Zolertia Firefly boards
  • 5 ST B-L072Z-LRWAN1 boards
  • 5 BBC micro:bit boards
  • 5 Microchip SAMR21 boards

The panel of offered MCUs and radio chipsets is intended to grow (total available is 64), and can include your own boards, just follow our documentation to start, and we’ll be glad to physically plug them in LeCube.

We hope you will enjoy working with this new space.

New boards available on Saclay site

22 Nov 2018

We are very happy to announce the release of a new batch of 46 boards on the Saclay site of IoT-LAB.

With these new boards, the possibilities already provided by IoT-LAB are even more extended:

  • The boards are from different vendors: NXP, Microchip, ST, Nordic, Phytec, etc
  • The boards provide different radios: 802.15.4, BLE, WiFi, Sub-GHz

The boards with 802.15.4 radio are deployed in the same room in order to allow developers testing wireless connectivity between heterogeneous platforms. Nodes with BLE radios are deployed in another room and are quite close to each other.
For more details on the deployment, please have a look at the Saclay site deployment page.

We recall that adding support for new boards can be done by anyone: just follow our documentation.

We hope you will enjoy working with these new boards.

New Web portal

28 Sep 2018

We are glad to announce the release of our new Web portal.

The new Web portal covers everything from the previous site, with some new features.

What’s new:

  • Faster dashboard with live experiments state
  • Intuitive ergonomic UI for experiment submission
  • Testbed status page with running experiments and nodes properties
  • Account management with user profile

Additional features will be added in the upcoming months as we complete them.

The portal is built with the Vue.js framework and leverages a new version of IoT-LAB public REST API.

New boards available on IoT-LAB: Zolertia Firefly and Arduino Zero

22 May 2018

After the addition of SAMR21 and LoRa boards we want to formally announce the availability of new types of boards on some IoT-LAB sites, which will permit a wider range of possibilities on the testbed.

  • 9 Zolertia Firefly boards, featuring two radios (2.4 GHz 802.15.4 Zigbee and sub-GHz), have been deployed on the Lille site. They are deployed throughout the building and, depending on the firmware you flash, will enable heterogeneous networking with co-located regular M3 boards.
  • 3 Arduino Zero boards with XBee shields have been deployed on the Saclay site. They are close to the existing M3 and SAMR21 boards and thus allow to test 802.15.4 (2.4GHz) interoperability between different types of radio.

If you have some hardware that you would like to see deployed on Iot-LAB, check out this documentation to implement the initial support and we will help you to finalize the on site deployment.

Don’t hesitate to reach out to us on for any issue you might have with the new boards.
