How We Built a Bluetooth Connected Mobile App in 4 Weeks

A development team successfully built a cross-platform tablet app in 4 weeks that connects to Bluetooth Low Energy devices, configures them, and visualizes pressure sensor data in 3D. The project used React Native with Expo, react-native-ble-plx for Bluetooth connectivity, and Three.js for 3D visualization. Key success factors included a small co-located team, rapid prototyping with established tools and component libraries, and close collaboration with the hardware inventor who worked on-site throughout the project.
