I have previously integrated the WaterLinked DVL with my BlueROV2. During testing today I continuously lost connection in QGroundControl to the ROV.
Having troubleshot every part it seems to be the ethernet switch setup.
The switch itself is a RTL8306E. aliexpress, (not the most reliable place to source electronics but it has done the job)
The power for it was just spliced out of the on board 5V 6A regulator (which is probably why the connection kept dropping)
A more robust setup is definitely needed as this was the way it was originally done while under time constraints. (which worked very well as I had posted here)
Could anyone advise on a better setup/parts? To note: the DVL is powered directly off of the main busbar.
