JuanMcd/expo-app: Expo-app

This release contains the full source code of the React Native mobile application developed using Expo. The app functions as a gateway between the embedded device (AMB82-Mini) and the cloud-based platform.

It includes:

BLE UART communication with the AMB82-Mini using secure UUIDs.

Real-time reception and parsing of JSON alerts from the device.

Offline queue management with retry logic using AsyncStorage (retries every 30 seconds).

HTTPS POST transmission to the backend (TLS 1.3 encrypted).

Basic UI for BLE device scan, connection, and alert status display.

Configuration files and permission settings for Android builds.

The application was compiled as a production APK and used in real urban driving tests. This work supports the study: Development and Field Validation of a Low-Cost Embedded Driver Monitoring System Using AI-Based Vision Algorithms and IoT Connectivity.
