i have a BlueRov2 and recently got an upgrade to a fathom-x tether box, it ran with some problems at first since i had to do the ipv4 config with 2 addreses to get video and control
192.168.2.1 – 255.255.255.0
192.168.2.3 – 255.255.255.255
With that config, at first that seemed to work, Q control was working fine and the unit seemed to be ok.
After a short trip to the dive site the Rov will not get a link light and wont send video to the topside comp.
After opening up the case i pulled the blue tether wire from the negative connection on the fathom-x board in the Rov side and video came online, but not control.
I´ve read all the info on bluerov site and ardsub, downloaded all, reset all, new flash img and all. and cant seem to make it work.
