Northern Tools partnered with Technostacks to design a mobile application capable of connecting to generator hardware through BLE. The solution allows users to manage fuel levels, diagnostics, and servicing schedules efficiently, reducing downtime and enhancing generator performance.

• Bluetooth Integration: Establishing a reliable Bluetooth connection for seamless communication between the app and generator hardware.
• Real-Time Data: Ensuring continuous data transfer and notification delivery for status updates, diagnostics, and servicing.
• Write Operations: Allowing users to clean alerts and update hardware settings via the app.
• Offline Access: Providing access to the last retrieved data even when disconnected.

Technostacks utilized Flutter to create an intuitive mobile application with the following features:

Bluetooth Connection Workflow

• Device Discovery: Scanning and identifying available Bluetooth devices.
• Pairing: Authenticating and pairing the app with the target hardware.
• Connection Establishment: Ensuring a stable connection using BLE profiles.

Data Read Operations

• Real-Time Status: Displaying generator power, remaining runtime, and hour meter data.
• Servicing Insights: Providing service schedules based on hours or days left.
• Diagnostics Information: Reading voltage and amperage details for generator performance monitoring.

Data Write Operations

• Cleaning alerts via the app, which communicates changes to the generator hardware.

Additional Features

• Local Notifications: Notifying users of critical alerts.
• App Permissions: Allowing users to manage permissions directly from the app settings.
• Local Database: Ensuring offline access to the most recent data retrieved from the generator.
• Simulator Software: Providing simulation tools for testing read and write functionalities.

• Efficiency: Real-time updates enhance generator performance monitoring and maintenance scheduling.
• User Experience: A seamless interface ensures ease of use and actionable insights.
• Reliability: Offline access to historical data provides convenience and operational continuity.
