Has anyone had any luck getting the image on the following site to publish messages via ROS on the Navio+Rpi combo?

Everything has built properly, and the topics are publishing over UDP to my MASTER but the messages are blank. I had to build their custom messages on the master in order to pull them down properly so I thought I might have introduced and error. To test that that wasnt the issue, I tried to run the module using the pi as the MASTER within the env the guys at CCtronics built and I got the same result: the message shows up but is completely blank.

Thanks!
