RIOT/dist/testbed-support

RIOT integration into IoT-LAB

Check the Wiki to see how to build and run RIOT on FIT IoT-LAB: https://github.com/iot-lab/iot-lab/wiki/Riot-support

Control IoT-LAB via Make

Requirements

This feature requires to have a valid account for the FIT IoT-LAB (registration there is open for everyone) and the iot-lab/cli-tools to be installed.

Description

The folder dist/testbed-support/ contains a Makefile.iotlab that defines some targets to control RIOT experiments on IoT-LAB using the GNU Make build system. In order to use this, one has to include this Makefile at the end of the application's Makefile, like this:

include $(RIOTBASE)/dist/testbed-support/Makefile.iotlab

Variables

This Makefile introduces some additional variables (default values in brackets):

• IOTLAB_NODES (5)
• IOTLAB_DURATION (30 minutes)
• IOTLAB_SITE (grenoble.iot-lab.info)
• IOTLAB_TYPE (m3:at86rf231)
• IOTLAB_AUTH ($HOME/.iotlabrc)
• IOTLAB_USER (taken from $IOTLAB_AUTH)
• IOTLAB_EXP_ID (taken from first experiment in running state)
• IOTLAB_EXP_NAME (RIOT_EXP)
• IOTLAB_PHY_NODES
• IOTLAB_PROFILE
• IOTLAB_EXCLUDE_NODES
• IOTLAB_LOGGING
• IOTLAB_TMUX

Format of a Resource ID

Both variables IOTLAB_PHY_NODES and IOTLAB_EXCLUDE_NODES use the resource id string format as specified in the output of iotlab-experiment submit --help. An example would be: 1-3+7+10-13

Targets

It defines the following targets:

• iotlab-exp
• iotlab-flash
• iotlab-reset
• iotlab-term

Please note: All targets that require an already running experiment will use the first experiment of the user that has already entered state "Running" if IOTLAB_EXP_ID is not set.

iotlab-exp

This schedules a new experiment on the FIT IoT-LAB and waits until it enters "Running" state. It will request IOTLAB_NODES nodes of type IOTLAB_TYPE for IOTLAB_DURATION minutes at site IOTLAB_SITE using IOTLAB_PROFILE (if provided). With IOTLAB_PHY_NODES it is possible to choose specific nodes for this experiment by using the resource id string format as described above. Note that the usage of IOTLAB_PHY_NODES ignores IOTLAB_NODES. It will also flash the binary of the current application to all registered nodes. The name of the experiment is set to "RIOT_EXP" or "RIOT_EXP_$(IOTLAB_EXP_NAME)" if IOTLAB_EXP_NAME is defined. If IOTLAB_LOGGING is set to 1, then the output of all nodes will be logged on the server into a file called "RIOT_LOG--".

iotlab-flash

This target updates the application on all registered nodes of the given experiment to the current version of the application. Certain nodes can be excluded by listing them in the IOTLAB_EXCLUDE_NODES variable using the resource id string format as described above.

iotlab-reset

This target resets all registered nodes of the given experiment. Certain nodes can be excluded by listing them in the IOTLAB_EXCLUDE_NODES variable using the resource id string format as described above.

iotlab-term

Uses ssh to login the user on the IoT-LAB server of the specified site and start the serial_aggregator to communication with all registered nodes. If IOTLAB_LOGGING is set to 1, then closing the connection with CTRL+C/D will also quit the logging process. If you enabled TMUX with IOTLAB_TMUX, detach from the server-side tmux process with CTRL+A-D (or as defined in your server-side .tmux.conf file)
