Same data on all transducers

[Kupofty]

Hi,

I'm using a A50 DVL with ROS and I noticed that the beam0,1,2,3 topic returned exactly the same data whatever the situation.
The same thing can be observed in the subscriber_gui.py picture in the readme.md file
Aren't they suppose to measure and return different values (distance, validity, etc ) and would it be possible to have access to the data of each one ?

Thanks
