Worked on enhancing Bluetooth Low Energy (BLE) V2 advertisement reliability for ChromeOS within the google/nearby repository. Addressed a platform-specific issue by implementing a conditional logic in C++ that sets BLE V2 fast advertisements as non-connectable when running on ChromeOS, aligning with the platform’s limitations. This platform-aware approach improved stability and user experience by ensuring BLE advertisements behave correctly across different operating systems. The work focused on mobile development and platform-specific implementation, reducing support overhead and preventing edge-case bugs related to BLE connectivity. The solution demonstrated careful attention to cross-platform compatibility and robust handling of OS-specific BLE constraints.
