Worked on enhancing Bluetooth API interoperability in the espressif/esp-nimble repository by enabling seamless integration between C and C++ codebases. The approach involved wrapping Bluetooth service APIs with extern "C" declarations, allowing direct inclusion and use within C++ projects. This technical solution reduced integration friction for C++ developers and laid the groundwork for broader API reuse in mixed-language embedded systems. The work focused on C and C++ interoperability, leveraging skills in Bluetooth protocol development and embedded systems programming. No major bugs were addressed during this period, with efforts concentrated on delivering this foundational feature for improved cross-language development workflows.
