This is so wrong. How will the tablet be able to connect to anything inside a steel box on the side of a truck?
Who designed the hydraulic system? Is it working now?

We already worked that one out; by adding 50 ohm Coax cable to the HC-05's trace, and an antenna outside the steel box. We are therefore still able to connect to it.
I believe the hydraulic system is currently working, but using a manual potentiometer to control the flow valve. So in the cabin of the truck, there is a simple dial to turn to increase/decrease the flow.
