I’ve built a prototype around an ESP32-based sensor board and now need a small, clean mobile interface that can pull the live readings and present them in real time. The firmware is already streaming the data; what’s missing is the bridge between the board and a user-friendly app. Here’s what I’m aiming for: • A lightweight mobile application (Android, iOS, or cross-platform—whichever you’re most comfortable with) that discovers the ESP32, establishes a secure connection, and continuously retrieves the sensor values. • A simple but responsive UI that shows the live data numerically and as a chart, plus a basic log/history view that can be exported (CSV or JSON is fine). • Clear, well-commented source code so I can extend or brand it later, along with concise setup notes for replicating your build environment. • If the ESP32 firmware needs minor tweaks to optimise the data flow, include those changes in the final hand-over. This must be done using BLE. Focus is on the ESP32 side while the app is mainly used for end-to-end testing. Once you’re done I’ll test the app against my hardware; acceptance is a smooth connection, consistent real-time readings, and a successful export of at least one session log.
