Worked on enhancing the reliability of MQTT messaging within the OPEnSLab-OSU/Loom-V4 repository by modifying the default Quality of Service (QoS) level in the MQTTComponent class. Focused on C++ development and the MQTT protocol, the approach involved changing the default publishMessage QoS from 2 to 1, ensuring at-least-once delivery and reducing the risk of message loss in unreliable network conditions. The update maintained compatibility with existing explicit QoS overrides and included a code formatting pass using clang-format. This work improved data integrity and delivery guarantees for IoT and edge scenarios, reflecting a careful, risk-aware engineering process.
