how to implement a profile of energy consumption monitoring of nodes on fit iot lab

[yahya-93]

Hi everyone
I want to test the AES message encryption mechanism on M3 and ST-Lorawamn nodes and collect information about the energy consumption of the nodes during the encryption phase and the computing time
the problem I found is that the experiment on fit iot lab can't be launched using a power consumption monitoring profile without the tutorial-M3.elf firmware
im getting the following message error
rbah@grenoble:~/iot-lab/parts/contiki/examples/ipv6/rpl-udp$ plot_oml_consum -p -i /.iot-lab/255409/consumption/m3_103.oml

SVP CAN U HELP ME

Hi @yahya-93
I'm sorry but it's impossible. Indeed the ST-Lorawan nodes don't provide this feature.
We will soon deploy a fix to check that profile monitoring is allowed on the nodes (i.e. monitoring hardware is available on the IoT-LAB gateway) and in this case returned an error when updating or associating profiles during experiments submission.
Sorry for the inconvenience.

Hello @fsaintma , thank you for your reply.
I have a question please
I want to use a M3 node to monitor the power consumption. while in the existing tutorial on the platform website associates the power consumption profile to the firmware tutorial_m3.elf which is created in advance to turn on/off the device LEDs periodically
How can we use other firmware (if they exist. where can i get them) to update and associate profiles during experiments submission which allow to use the sensors of node M3 to collect information like temperature then launch the energy consumption profile
