The Companion is not detecting your Pixhawk, it seems to be the source of the issue.
Try connecting directly to a PC with QGC and flashing Ardusub again. If this does not work, you can force it to erase all parameters by flashing another vehicle (Copter/Plane/Rover) and then Ardusub again.
Also check that the sd card inside the Pixhawk (not the raspberry) is ok. It is necessary for Ardusub to work.
Como hago para forzar eso me podrías enviar algo mas detallado por favor
Hi Roger, I think you might need a replacement hardware. Please email firstname.lastname@example.org and let them know about your problem here, and when you purchased your ROV.
