Live measures. A monitoring profile now has outputs. With streaming, the consumption, radio measures and GPIO events reach the IoT-LAB database during the experiment: follow them in your browser or query them from your scripts, for 30 days. No need to wait for the end of an experiment any more. See Monitoring outputs.

JSON lines files. With the jsonl output, the measures of the experiment are written as one JSON object per line, readable with any language. The OML format is deprecated. It stays the default for the existing profiles, and we will announce the date of its end.

GPIO events. Your firmware toggles a GPIO line of an M3 or A8-M3 node, and the testbed records it with its time. Use gpio2 together with the consumption: gpio1 stops the consumption measures. See GPIO events.

Debian images, your own images. The open Linux nodes boot Debian 13 (trixie) instead of Yocto, now deprecated, and you can boot your own image: an ordinary Docker image built on the IoT-LAB one. See Linux and the tutorial.

Web shell and live sniffer. Open a root shell on your open Linux nodes from the web portal, without SSH client or key, and follow the packets of the radio sniffer live in a tshark like view. Both are also available from your computer with ws-cli-tools: iotlab-ws-shell and iotlab-ws-sniffer, the latter for Wireshark. See Linux and Radio monitoring.

New nodes. The NVIDIA Jetson Nano and Jetson Orin are available in Saclay: GPU nodes, with Docker, as open Linux nodes.

A testbed on your desk. The local testbed runs a small IoT-LAB on one Linux machine, with your own boards.

Upgrade the CLI tools to use these features: pip install -U iotlabcli.

Your image is an ordinary Docker image, built on top of the IoT-LAB one and pushed to Docker Hub:

FROM fitiotlab/iot-lab-open-linux-base:1.0.4
RUN apt-get update && apt-get install -y --no-install-recommends htop \
    && rm -rf /var/lib/apt/lists/*

Add it to the nodes of your experiment, and they boot it:

iotlab-experiment submit -n my-image -d 30 -l grenoble,a8,1-5,image=docker.io/<you>/my-image:1

The tools of your experiment are ready on every node from the start, the same on all the nodes, and the image is yours to keep and share.

What changes with the new images:

• each node has its own root filesystem, removed at the end of the experiment (with Yocto, the nodes of an experiment shared one): install in your image, with iotlab-ssh run-cmd, or in ~/shared;
• the journal of each node is copied in ~/.iot-lab/<experiment id>/journal/<node>/ at the end of the experiment.

Upgrade the CLI tools to 3.4.0 (pip install -U iotlabcli) to use image=, or use the web portal. Read Linux for the details and limits, and follow the tutorial for your first image.

We improve our deployment of 30 Pycom boards to support not only MicroPython firmware but any generic firmware for ESP32 MCU.

Old Pycom boards are now available under generic support:

• ESP32 LoPy4

We are also very happy to announce the release of 5 new boards on the Strasbourg site:

• ESP32-C6-DevKitC-1

• Some nodes will be slightly moved.
• A new ground truth will be measured and published

Several dwm1001 nodes were initially fixed to furniture which, with time, has created contradictory needs in an active office building :

• These furniture items should not be moved to maintain testbed reproducibility and an accurate ground truth
• It is sometimes required to move them (change in the floorplan, need to reach a socket behind a cabinet, …)

To solve this, they will be mounted on the ceiling. We will attempt to put them as close as possible to their previous position but the mounting points cannot be installed arbitrarily, therefore there will be some change in their position on the XY plane (at most 35 cm). We will however set them at the same height. 

The following dwm1001 nodes will be impacted : 1, 2, 5, 6, 9, 10, 62, 69, 70, 77, 81, 85, 89, 93, 94. These changes will occur over the coming weeks, starting today with nodes 69 and 70.

Because these dwm1001 nodes will move and we have recently installed new dwm3001 nodes, we will re-measure the ground truth. Since we now have access to a 3D LIDAR scanner, this new ground truth will have a 1mm accuracy over the whole building. The old node positions will be removed on the iot-lab website and on the MQTT broker as soon as the nodes are moved, and they will be updated as soon as the new ground truth is available.

• 4 Qorvo DWM1001 boards have been deployed in an anechoic chamber.
• 42 new Qorvo DWM3001 boards have been deployed in the same environment as the DWM1001 (38 in an office setting, and 4 in an anechoic chamber).

These new nodes are already available in our production environment, you can start experimenting with them as soon as you wish.

The positions of the new nodes are not yet known. A 3D LIDAR scan of the whole floor with sub-cm accuracy is scheduled in the coming weeks to establish a reliable ground truth for ranging, localization and time synchronization experiments.

SLICES-RI (Scientific Large Scale Infrastructure for Computing/Communication Experimental Studies) is a flexible infrastructure designed to support large-scale, experimental research focused on networking protocols, radio technologies, services, data collection, parallel and distributed computing and in particular cloud and edge-based computing architectures and services. Since 2021, SLICES-RI managed to launch several projects to define a common architecture of the targeted infrastructure.

The french node of SLICES-RI, called SLICES-FR, plan to integrate major french infrastuctures of the domain like IoT-LAB and bring them to SLICES-RI. The IoT-LAB is defining a roadmap for a smooth migration SLICES-RI to avoid downtime for the users.

We are very happy to announce the release of 20 new boards on the Strasbourg site.

• Qorvo DWM1001

We are proud to announce the arrival of a new IoT-LAB site located in the city of Toulouse (Occitanie).

More precisely the nodes are deployed at the IUT Blagnac, in collaboration with the IRIT/UT2J laboratory. You can find information about the actual deployment by following this link.

This site is catered towards indoor localisation in varying setups, but can host experiments on other topics such as time synchronisation.

More development will arrive soon.

We are very happy to announce the release of new boards on the Grenoble site.

You will find two new LoRa development boards:

• Nucleo WL55JC
• SAMR34 Xplained Pro evaluation kit

As a reminder, a The Things Network LoRa gateway is deployed on the Grenoble site which allows you to follow the tutorials on Labs.

We have also deployed embedded Linux boards based on Raspberry Pi hardware. The boards are equipped with a co-microcontroller (i.e. SAMR21 Xplained Pro) to manage 802.15.4 communications.

• Raspberry Pi 3

For more details on the deployment, please have a look at the Grenoble 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.

We are proud to announce the arrival of a new IoT-LAB site located in the city of Nantes (Pays de la Loire).

More precisely the nodes are deployed at the IETR laboratory of the Polytech’Nantes engineering school, in collaboration with the LS2N Laboratory. You can find information about the actual deployment by following this link. More development will arrive soon.

We warmly thank the people who worked on this project and in particular Sébastien Pillement, Marc Brunet and Amine Benomar from the University of Nantes.
