I am trying to develop and AUV using the ArduSub firmware on a Pixhawk. In the early stages at the moment we are trying to have the vehicle tethered for easy testing and debugging.
I know that using a Pixhawk with ArduSub firmware and a RaspberryPi with ArduSub-raspian image I can easily connect to the reapberrypi from a laptop using an ethernet and detect the pixhawk in the QGroundstation
But instead of the rasperrypi I want to use a mini-pc connected to the surface computer via ethernet and establish the connection with SSH.
I have done that with the SITL simulator but I couldn’t detect the simulated Pixhawk from the surface computer running QGroundControl, the following figure can explain the situation much better
