Fruits Electronics is a mobile IoT solution for intelligent control and real-time management of BLE-enabled devices across industries. It combines a Flutter UI with custom BLE communication and encrypted packet handling.
Challenge
Industrial BLE devices needed a mobile console to discover paired units, open configuration, and exchange commands securely — not a generic Bluetooth scanner.
Solution
Built a Flutter app with GetX, GATT-based BLE communication, AES-encrypted packets, and a home list of paired devices for view/configure flows.
System architecture
Flutter UI (GetX) speaks BLE GATT to hardware. Command/response payloads are AES-encrypted. SharedPreferences stores paired-device prefs. Users select a device from the home grid, then configure or control it over the encrypted BLE channel.
My contribution
Implemented the Flutter IoT client — paired-device home UX, BLE GATT communication, and AES packet handling for Fruits Electronics hardware.
Technology
Engineering challenges
- Custom BLE GATT profiles instead of off-the-shelf consumer BLE APIs alone.
- Encrypting packets without making the UI feel slow or fragile.
- Clear paired-device identity (IDs/labels) for industrial units in the field.
Implementation
Delivered the Home paired-device grid, BLE connect/configure paths, encrypted packet send/receive, and supporting settings/info navigation.
Outcome
Available on Google Play as Fruits Electronics.
