Easily transform digital notes into printed treasures with BLE thermal printing. Capture, connect, and print on-the-go!

Introducing “Print Notes”, the definitive app for transforming your digital scribbles into physical keepsakes. Connect seamlessly via Bluetooth Low Energy (BLE) to your thermal printer and bring your notes, ideas, and reminders to life. Whether you’re a student jotting down key points, a professional capturing meeting minutes, or simply someone who loves the feel of a printed note, our app ensures swift, easy, and reliable printing.

This project involves developing a native Android application to facilitate truck Tachographs’ audit and diagnostic processes. The app establishes Bluetooth Low Energy (BLE) communication using HC-08 Bluetooth module, which is connected to the Tachograph via a 6-pin data connector. This setup ensures a reliable and efficient connection between the Tachograph and the mobile device.

The app’s primary purpose is to streamline the collection, analysis, and presentation of Tachograph data, enabling users to easily perform thorough audits and diagnostics. Through an intuitive user interface, users can access real-time data, generate reports, and identify potential issues, enhancing the overall efficiency and safety of truck operations.

This application is an essential tool for fleet managers and auditors, providing them with the necessary insights to maintain compliance and optimize their fleet’s performance.

The project involved creating iOS and Android mobile apps for a smart door lock, enhancing Smart Home automation and security. The apps integrate with the smart door lock using BLE and WiFi communication, providing residents with a secure, seamless control over their home access. Key features include real-time monitoring, remote locking and unlocking, and customizable access permissions. A continuous and stable connection ensures a reliable and user-friendly solution for modern home security needs.

The Bartender App, developed with the Flutter framework, allows users to view recipes for various drinks and cocktails. A standout feature is the product scanning capability, which retrieves recipes based on the scanned bottles and ingredients added. The app also provides detailed information on cocktail ingredients and allows users to explore a wide variety of drink recipes. The app leverages Flutter Bloc for state management, Dio for networking, go_router for routing, and Firebase for backend services.

The CitrusDev web development team faced several challenges while developing the project. One of the significant challenges was designing a system that could differentiate between various types of cars, such as the cars of organizers and transport delivery drivers (who only enter within the framework of a particular event) and the cars of tenants (who enter on a regular, more long-term basis). This required a robust algorithm that could recognize different car categories and their quotas.

This project case was developed for Polyscale, a company of approximately 50 employees operating in the appliance, electrical, and electronics manufacturing industries. The department we collaborated with specialized in developing, manufacturing, and distributing light guide plate (LGP) based systems.
