iam working on tethered drone where i would like to use pixhawk. Is it possible to connect pixhawk with computer wiht wire (UTP) and control drone with qgc?
another question(stuppid one):
is it possible to fully operate pixhawk (operate drone with qgc) while is conected with usb cable to computer? This would be the easiest solution for my project.
I need solution to control a drone without rc. Any other solution?
You’ll get better results using serial rather than USB, but they aren’t the only two options.
Getting any real distance will require a bit of engineering. Have a look at how blue robotics tether their sub.
For long distance serial connections, RS485 can be a good solution. It is a robust differential signal protocol, and the drivers (i.e. SN75176) are cheap.
Its either differential driver or fiber optic.
