Hello, I plan on using an arduino board to add a remote start to my car. I tried using a HC-05 to communicate with my phone but the range is far too low. The goal is to be able to start my car that’s parked in the street in front of my house from my room. Distance is roughly 50 feet and the signal would have to pass through 1 drywall, 1 brick wall and lastly through the metal trunk which is where the module will be located. It doesn’t have to be bluetooth but I would like to be able to communicate with it from my phone. This is a budget project so best bang for my buck is preferred.
