Developed and released the Arduino Bluetooth Command Library, BleCommands.Arduino, within the arduino/library-registry to streamline Bluetooth Low Energy command handling for Arduino projects. Focused on Arduino programming and library development, the work introduced a reusable API that standardizes BLE interactions, making it easier for developers to integrate Bluetooth features into their IoT solutions. The library, written in plaintext, enhances discoverability and reuse by leveraging the centralized registry, supporting scalable and maintainable Bluetooth communication. This contribution laid the groundwork for future Bluetooth-enabled Arduino applications, reducing integration complexity and supporting faster development cycles for teams building connected hardware solutions.
