Bluetooth App for Arduino Car

I have a small toy car that already runs on an Arduino-based motor driver. What I now need is a companion mobile app, connected via Bluetooth, that can do two things reliably:

• Send simple movement commands—forward, reverse, left and right—at the tap of on-screen buttons or a virtual joystick.
• Show a live video stream coming from the camera mounted on the car, so I can drive it while seeing exactly where it’s heading.

The Bluetooth pairing will be handled with a standard HC-05 (or comparable) module that is already wired to the Arduino. On the camera side I have flexibility; if you have a preferred off-the-shelf Bluetooth camera or a way to piggy-back the feed through the existing module, I’m open to that—as long as the stream remains smooth enough for basic indoor navigation.

Deliverables I expect:
1. Source code for the mobile app (Android is fine; cross-platform with Flutter or React Native is even better).
2. Updated Arduino sketch that listens for the movement commands you implement.
3. Clear setup instructions so I can compile, upload and pair everything myself. A short demo video showing the system working will be the final acceptance step.

No extra speed control, obstacle alerts or configuration panels are required at this stage; just solid directional control and dependable real-time video.
