OpenBLE, Swagger for Bluetooth

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.

In the maker’s words, at launch

OpenBLE is an API specification language and client generator for Bluetooth services built on the generic attribute (GATT) profile. Bluetooth development is a mess. Too many datasheets, too little documentation and SDK fragmentation across platforms. I built this tool to improve documentation, version control and…

  Agents.json – OpenAPI Specification for LLMs2025 · github.com · ▲212

  Hey HN, we’re building an open specification that lets agents discover and invoke APIs with natural language, built on the OpenAPI standard. agents.json clearly defines the contract between LLMs and API as a standard that's open, observable, and replicable. Here’s a walkthrough of how it works: https://youtu.be/kby2Wdt2Dtk?si=59xGCDy48Zzwr7ND. There’s 2 parts to this: 1. An agents.json file describes how to link API calls together into outcome-based tools for LLMs. This file sits alongside an OpenAPI file. 2. The agents.json SDK loads agents.json files as tools for an LLM that…

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
