Scale-up

GOAL: Scale-up in a realistic environment.

IoT-LAB provides a very large scale infrastructure suitable for testing small wireless sensor devices and heterogeneous communicating objects.

Even if the ESP32 is not currently among the supported hardware, IoT-LAB supports FreeRTOS.

Once you have setup a user connect to a lab by ssh, as an example

ssh vitalett@grenoble.iot-lab.info

Follow the instructions here to run FreeRTOS on IoT-LAB
The reference code is available on https://github.com/iot-lab/openlab and in particular we are inetrested in the tutorial
Once the code has been compiled, it can run into an experiment as explained here
A quite unique feature, is the ability to perform consuption monitoring as explained here. To plot the graphs, download the oml files and use the following tools

IOT-LAB

Run a Lorawan experiment

ssh vitalett@saclay.iot-lab.info

git clone https://github.com/FreeRTOS/FreeRTOS-LTS.git
cd FreeRTOS-LTS/FreeRTOS
git clone https://github.com/Lora-net/LoRaMac-node.git
cd cd LoRaMac-node/
