Worked on the nrfconnect/sdk-nrf repository to enhance the reliability and memory safety of a Bluetooth-based Connection Time Synchronization Sample for embedded systems. Addressed a memory corruption risk by refining the use of memset in C, ensuring that only a single entry was cleared during connection state resets. This targeted fix eliminated out-of-bounds writes, improving stability and reducing the potential for crashes in edge-case scenarios. The work demonstrated disciplined memory management and careful bounds checking, aligning with best practices for safety-critical IoT software. Delivered a focused, traceable patch that improved maintainability and reliability in a critical connectivity sample.
