I've installed Ubuntu 14, and UbuntuARM ROS version on the persee machine. I've installed ros_astra_launch to stream depth topics. I would like to access the depth topics with ROS_MASTER_URI and ROS_IP mechanism.
Everything is okay but I've seen that there is a frequency decreasing of the topics in the network. So I've checked that the bandwidth of the topics that I need to share is more than 100Mb. I've seen also that the cpu can works with 1000Mb ethernet.
I've used the mii-tool and I've obtained:
eth0: negotiated 100baseTx-FD
in the same ethernet switch where others machines work with 1000baseTx.
So the question is, is it a software configuration inside the built-in Ubuntu or is it a hardware configuration inside the persee that doesn't allow to have 1000Mb?
