Re: [riot-devel] Measuring power on the iot-lab testbed
Hi Peter, don't worry, I think it's an IoT-Lab problem. Some nodes have this unstable consumption graph, it's tracked on the following issue: https://github.com/iot-lab/iot-lab/issues/148 Can you try with one good node: like Grenoble 1+9+12 and see if the problem remains? I added iot-lab admin as CC to let us follow the discussions.

Re: [riot-devel] Measuring power on the iot-lab testbed
Hi Gaëtan, I tested the RIOT hello-world- and also your simple_idle example on different nodes that are noted as ok in [1] (1, 9, 35, 40, 41 45). The spurious peaks were existent in all experiments. Regarding the sawtooth-problem for me it still seems to be RIOT-dependant because the sawtooth does not apply to your simple_idle example. This questions addresses all RIOTers. Looking forward to get helpful feedback by anyone :-)!

[riot-devel] Measuring power on the iot-lab testbed
