I need end-to-end development for a Tire Pressure Monitoring System that reads pressure and temperature from wireless sensors over BLE, processes the data on an embedded controller, and mirrors everything in a cross-platform mobile app. Firmware • Build reliable, low-power BLE firmware that continuously scans, pairs with the sensors, and streams raw pressure/temperature values to the host MCU. • Implement data validation, unit conversion, and error handling directly on the device so only clean, usable figures reach the UI layer. Mobile application (iOS & Android) The same codebase should compile for both iOS and Android—React Native, Flutter, or any approach you are comfortable with is fine as long as performance is smooth and native BLE APIs are used. The app must: • Auto-detect the TPMS device, subscribe to its live feed, and store recent readings locally. • Present a dashboard that blends an easy-to-scan numeric table with clear graphs for trend analysis. • Trigger three forms of low-pressure alerts: an audible tone, an on-screen visual cue, and a push notification, each configurable by the user. Dashboard on the device head-unit The embedded controller outputs data to a small in-car display. I want the same combination graphical/text interface as the phone app, scaled for a 4–5″ LCD, with simple menu navigation handled by push buttons or capacitive keys. Acceptance criteria 1. BLE link remains stable for a minimum 50 m range inside a vehicle. 2. Pressure deviation of ±1 psi from a calibrated gauge. 3. All three alert channels fire within 2 s of crossing the low-pressure threshold. 4. iOS (15+) and Android (10+) builds pass App Store & Play Store BLE permissions requirements. If you have solid embedded C/C++ for BLE plus cross-platform mobile experience, let’s get this rolling.

This is a strong fit for a BLE-centered embedded + mobile architecture, and the key to making it reliable is clean separation between sensor acquisition, validation logic, and UI presentation. For the embedded side, I would use a robust low-power BLE architecture (ESP32, Nordic nRF52, or similar depending on sensor protocol compatibility) with continuous scanning, packet validation, filtering, unit conversion, watchdog recovery, and stable communication handling before data reaches the display or mobile layer. For the mobile application, Flutter or React Native with native BLE integration would work well for maintaining a single codebase across iOS and Android while still handling background BLE permissions and notifications correctly for App Store/Play Store compliance. The dashboard UI can share the same design language between the mobile app and the in-vehicle display, including live tire data, trend graphs, configurable pressure thresholds, alert management, and local storage of recent readings/history. I can support the complete workflow including firmware, BLE protocol handling, embedded UI, cross-platform app development, alert logic, testing strategy, and integration validation against your range and pressure-accuracy requirements.

I’ve worked on BLE-heavy embedded/mobile systems like this where reliability matters more than features on paper. On firmware side, I’d start with a low-power scan/pairing layer tuned for in-vehicle interference, then build a clean GATT stream handler that normalizes pressure/temp packets as early as possible. I usually add validation, unit conversion, timestamping, and basic filtering on the MCU so the mobile layer never deals with noisy data. If packets drop, I buffer briefly and resync instead of forcing reconnect loops. For the app, I’d go with Flutter or React Native using native BLE bindings, auto-discovery, and a local store for recent readings. Charts + table would be driven off a single shared state model. Alerts (sound, UI, push) would be gated with hysteresis so they don’t flicker on borderline values. Head-unit would mirror same data model with a lightweight C++ UI layer optimized for 4–5” rendering. What BLE chipset/protocol are your sensors using, and is the MCU already selected?

Having successfully developed low-power BLE communication modules for embedded systems, I'm confident in my ability to deliver a robust and efficient firmware solution for your BLE TPMS. My experience includes optimizing scan intervals and connection parameters to maximize battery life while ensuring reliable sensor data acquisition and transmission, mirroring the continuous scanning and streaming requirement. My technical approach will leverage the STM32 ecosystem for the host MCU, utilizing its HAL/LL libraries for direct hardware control and FreeRTOS for efficient task management. For BLE, I'll integrate the appropriate vendor's SDK, focusing on a state machine architecture for sensor discovery, pairing, and data reception. Data processing will involve implementing CRC checks, unit conversions (PSI/kPa, °C/°F), and robust error handling for sensor disconnects or invalid readings, ensuring only clean data is passed to the application layer. The mobile app will be developed using Flutter, allowing for a single codebase for both iOS and Android, integrating seamlessly with the BLE firmware for real-time data display and alerts. What are your target battery life expectations for the wireless sensors? Also, have you considered specific protocols for sensor discovery beyond standard BLE advertising, or will a simple scan suffice? I'm eager to discuss your project in more detail and outline a precise timeline.
