## AI overview

A GSoC 2026 proposal for Haiku aims to modernize the operating system's Bluetooth stack and implement the Bluetooth HID profile. The planned work includes completing HCI commands, improving pairing and Link Key persistence, and handling disconnection and timeout events.

## Source excerpt

Hello! I'm Mohammed R. Attia, a 2nd-year Computer Science Student. I've been accepted into Google Summer of Code (GSoC) 2026 with Haiku, with my proposal titled "Modernizing Haiku's Bluetooth Stack: HCI Completion and HID Profile Implementation." About Me I consider myself a competitive programmer and a software engineer. I haven't decided on a specific specialization in software engineering just yet; rather, I'm interested in systems development and low-level programming. You can check my GitHub for more information about my latest projects. I go by the handle mohammedrattia in many places on the internet, so feel free to reach out :). How did I get here? I first learned about Haiku while searching for GSoC organizations to contribute to. It was my first time learning about a desktop operating system other than the famous trio: Windows, macOS, and Linux. So, I started by reading the GSoC guide and joining IRC. I remember that the process was smooth because the guide contained everything, and people on IRC were welcoming and supportive. Then, I started working towards building Haiku, and I got my first commit merged into Haiku after several days. Current Goals The main goal of my proposal in GSoC is to modernize the Bluetooth stack. Currently, the Bluetooth stack in Haiku can't communicate effectively with modern Bluetooth devices because of the outdated standards it uses. However, making the Bluetooth core perfectly align with modern standards won't benefit Haiku users because it would still need a Bluetooth Profile to perform a useful task. One of the most common uses of Bluetooth is Human Interface Devices (HID) (e.g., keyboards and mice). Accordingly, this project will build the HID Bluetooth profile to provide useful functionality for Haiku users. The following three sub-sections contain a brief specification for the goals of the project from my GSoC proposal. Modern HCI Event & Command Handling Build upon the recent SSP/EIR groundwork by implementing the remai
