Data visualization: Seamless BLE integration for real-time insights
Ideas. Concept. Solution.
Our client approached Devomech Solutions with an innovative vision: to develop a Flutter mobile application that seamlessly connects to custom-built hardware using Bluetooth Low Energy (BLE) technology. The goal was to transmit and receive data between the app and hardware, enabling real-time data visualization on an oscilloscope-like graph. The client required a mobile application that could establish a BLE connection, display real-time data, save data to a file, plot saved data on-demand, show a timer display, and indicate the connection status and data receiving state. Additionally, the app needed to provide an options page for configurations and related information, as well as a device selection page for BLE connectivity.
Design, development, and deployment
Central to the app’s functionality, the real-time oscilloscope graph accurately illustrates dynamic data changes. This achievement results from resource optimization, ensuring user-friendly experiences and accurate data insights.
The app was designed to be highly scalable and compatible with a wide range of Android operating systems, from Android 5.0 to the latest versions.
Thorough testing was conducted, including stress testing and handling potential exceptions or errors during data transfer, plotting, and file management, and iterations were made to improve reliability.
We prioritized efficient memory and computational resource management to facilitate smooth and responsive real-time graph plotting. Users could also plot previously saved data on-demand. Moreover, through an accurate timer display built to showcase the elapsed time, users could pause, reset, or resume the data collection at any time.
Employing dynamic data handling, pruning outdated values, and optimized buffering, our app ensures responsive performance while minimizing memory footprint. Proactive memory management enhances user experience, long-term stability, and reliability.
Seamless BLE links high-frequency data acquisition, dynamic graph rendering, and optimized user experience for unparalleled performance.
Power-saving techniques were used to minimize battery consumption, ensuring a longer-lasting app experience.
Insights from the Team Lead
It was an exhilarating experience, leading a team of skilled developers to create a user-friendly interface that effortlessly captured and presented real-time data on an oscilloscope-like graph. We delved into the intricacies of establishing a robust communication channel between the app and hardware, implementing robust error-handling mechanisms, and optimizing power consumption. The journey highlighted the importance of meticulous design, efficient data processing, and compatibility with the latest technologies. Our team’s dedication and innovative approach resulted in a scalable and resilient solution that exceeded the client’s expectations, empowering users to gain valuable insights from their data with ease.

A BLE-enabled app for exercise monitoring
Ideas. Concept. Solution.
Undertaking an ambitious project to develop a cutting-edge Android tablet application for a valued client, Team Devomech Solutions created an application that could seamlessly communicate with the client’s custom-built hardware using Bluetooth Low Energy (BLE). The app was developed to allow users to personalize fitness targets, maintain a database to store user-specific information, monitor real-time data exchange related to physical exercises, and display exercise statistics through visually appealing graphs.
The app’s structure was designed using the Iterative Software Development model, allowing for flexibility and iterative improvements throughout the development lifecycle.
Design, development, and deployment
The team enabled the application’s capability to automatically scan for and connect to the hardware upon startup, as well as reestablish the connection if it was ever disrupted to simplify initial set-up.
The app’s architecture was designed to be highly scalable, allowing it to run efficiently on a wide range of Android devices, starting from version 5.0.
Close attention was paid to mirroring the client’s provided design to create a visually appealing graphical user interface.
The team ensured that the hardware communication adhered to industry standards and the app’s commands were reliably sent and resent until acknowledgment was received.
Comprehensive testing was carried out, encompassing all relevant test cases, to ensure the app’s quality and performance met high standards.
The app’s ability to handle high-speed data transmission ensured no data loss during exercise sessions, providing users with accurate and real-time exercise statistics.
As the founder of Illusio, I wanted to work on a new way of improving sports performance. We did that by creating a machine with data that was digital, intelligent, and represented in a beautiful and minimal design. Devomech Solutions helped us in enabling the WIFI logic control through Rasberry Pi Zero. I would want to work with them again as they did the job very professionally.
