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
