Hello, im making ROV that uses one RPi at underwater and one RPi on above water controller box. I want to take camera display and sensor values from ROV to the controller box and take controller values from controller box to the ROV. How can i make communication between 2 Pis?
With a long, flexible, waterproof cable and lots of sealant where it enters the submersible?
(Because, due to non-RPi-specific physics, aren't most common consumer forms of 'wireless' communication in the electromagnetic spectrum heavily attenuated by water?)
