I recevied this message from Seth at U of Cincinatti:
The new build of the firmware do not seem to work at all. I have tried this on 16.04 with both rev 5 and 6. The ROS node just spams Detected time offset of 1506704629.(some random decimal) over and over and over. The airspeed sensor still doesn't work I have tried everything I can think of and nothing works. I really need to be able to receive airspeed data and I can't do so on old builds of rosflight or new.
