In plain words
OpenBLE is an API specification language and code generator for Bluetooth GATT services, designed to address fragmentation and poor documentation in Bluetooth development. It provides tools for specification, version control, and code generation to speed up BLE program development. The frontend uses Web Bluetooth technology, eliminating SDK dependencies and platform-specific installations while offering browser-based compatibility. All components, including the specification, SDK, code generator, and testing framework, are built in JavaScript.
