Worked on the YeachanOkh/BANSHEE-Mechatronics-SPR24 repository to enhance drone communication reliability by refactoring the ESP-NOW protocol implementation. Focused on embedded systems and IoT, the developer updated the peer connection logic to consistently use the master MAC address, introduced a data receive callback for improved message handling, and revised button press logic to target the master device. Maintenance efforts included syntax corrections and code cleanup in C++, reducing build risks and improving code quality. These changes established a more maintainable and robust foundation for future development, supporting safer drone operations and clearer traceability of protocol-level changes within the project.
