Worked on the arduino/library-registry repository to deliver the SIM800_GSM_GPRS Library Integration, expanding the registry’s support for IoT workflows. Integrated a new repository link into repositories.txt, enabling SMS, call, and HTTP functionality over GPRS for Arduino, ESP32, and STM32 platforms. Focused on clear documentation and version control practices, the work included detailing library capabilities and compatibility within the registry notes. This addition improved the discoverability and completeness of the library registry, providing developers with simple APIs for network detection, IMEI retrieval, and event-driven SMS or call handling, thereby broadening options for cross-platform IoT integrations using text-based configuration.
