Project overview
The client, providing an open-source protocol stack for Bluetooth-enabled applications, sought to enhance its toolset with a Bluetooth Frequency Control System. To achieve this, they partnered with LARION, assembling a dedicated team of three specialists. Leveraging the Sdbus C++ library, CLI11, and Bluetooth on Linux, the team successfully developed the BlueZ++ Control Tool. This solution significantly improved Bluetooth communication, providing users with greater control and stability across their devices
Challenge: Developer Shortage
To support the development of Bluetooth-enabled applications, the company aimed to enhance its toolkit by introducing a Bluetooth Frequency Control System. This new feature would enable users to dynamically adjust the Bluetooth frequency range for each connected device, significantly improving communication quality.
However, the project faced a critical challenge — a shortage of in-house developers. To overcome this resource gap and stay on track with their roadmap, the company turned to LARION. With our strong technical expertise and proven track record, we were selected to provide development support and help bring this innovation to life.
Solution: Advanced Bluetooth Frequency Control Tool
The project operated under a fixed-cost model with a two-month delivery timeline, following the Waterfall methodology to ensure a clear, phase-driven approach. Our 3-member team—consisting of a project manager, developer, and quality controller—collaborated closely to move through planning, development, and testing in a disciplined sequence.
We leveraged technologies including the Sdbus C++ library for D-Bus messaging, CLI11 for building the command-line interface, and deep integration with Bluetooth functionalities on Linux.
The final BlueZ++ Control tool featured a well-architected system composed of three core modules:
- D-Bus Interface Module: Functioning as the communication hub, this module enabled smooth interaction between the Bluetooth Frequency Control Tool and other system services. It processed real-time D-Bus messages, allowing control commands, updates, and data exchange with the BlueZ stack.
- Bluetooth Protocol Module: This component handled all Bluetooth stack operations, including frequency adjustments, signal optimization, and core protocol tasks. It ensured the tool could efficiently manage connections and maintain strong communication performance.
- Command-Line Interface Module: Designed with user control in mind, this module offered a straightforward terminal-based interface. Users could issue commands, monitor system status, and dynamically adjust Bluetooth frequencies—enhancing both usability and flexibility.
With these integrated components, the tool delivered a powerful and responsive solution for dynamic Bluetooth frequency management.
Result: Precise Bluetooth Management for Devices
With smooth workflows and strong collaboration, the team successfully delivered the BlueZ++ Control tool on time and within budget. The tool enables efficient management of Bluetooth frequencies and seamless control over enabling or disabling specific devices. By minimizing interference and allowing precise frequency adjustments, it significantly optimizes Bluetooth communication and improves overall connectivity.
As a result, users gain greater control and stability across their Bluetooth-enabled devices, empowering them to enhance performance in increasingly complex and dynamic environments.
