I’ve just finished ballasting and testing my BlueRov2. In the last few minutes of the mission, the link to the ROV failed. Back on the test bench, I cannot get the FathomX link to work.
Steps in fault finding:
Connected direct QGroundcontrol to ROV Pi via ethernet. Works (updated Qgroundcontrol and Pi as well)
Removed tether, connected topside FathomX to Rov FathomX with 1m of spare twisted pair. Fail
Slim tether checked for continuity by bridging with a meter. Works.
Topside Fathom X on power shows power light constant, link light flashes on, then off at start up.
ROV Fathom X on power shows the same power light constant, link light flashes on, then off. Link light comes back on for a few seconds, then goes out.
