It covers RFCOMM implementation, xHCI improvements, Bluetooth stack and media fixes, HFP session functionality, and a Bluetooth SCO Media Kit add-on. RFCOMM and SCO are nearly ready for merging, while HFP still needs to be split, reviewed, and prepared for merging. ### Source excerpt Introduction The goal of this post is to document the changes I made during the GSoC period and the current state of the project. I would also like to thank waddlesplash for his continued support throughout the project. Progress So Far RFCOMM Protocol RFCOMM is now almost ready to be merged. It acts as the control channel required by HFP. The implementation includes: RFCOMM socket addressing and connection management DLCI multiplexing over a shared L2CAP connection SABM, UA, DM, DISC, and UIH frame handling MCC commands Credit-based flow control USB and xHCI Improvements During implementation, I found that the xHCI driver assumed all isochronous packets had the same size, which is not always true. The xHCI driver now supports variable-length isochronous packets and processes completed transfers in FIFO order instead of LIFO order. Bug Fixes A part of this period was spent fixing issues in the existing Bluetooth stack. The main fixes include: Correcting ACL packet splitting when packets exceed the L2CAP MTU. Holding socket references while working on them. Related changes include the L2CAP refactor,send-status fix, socket lifetime changes, and MTU packet fix Media Stack Fixes While working on Bluetooth audio integration, I found some bugs in the media stack. After initial work, waddlesplash took over these changes and implemented the actual changes. The improvements landed in the media auto-stop change and the live output reconnection change. Hands-Free Profile The first pass for HFP is done. It includes: Hands-Free service discovery through SDP. HFP session management. Basic AT-command parsing. The implementation is functional but work is needed to split the changes, getting it reviewed and making it merge ready. Bluetooth SCO Media Add-on The Bluetooth SCO Media Kit add-on has also been implemented. It discovers Bluetooth audio devices, exposes them through the Media Kit, and creates media nodes for headset playback and capture. It includes: Bluetooth headset disco ## \[GSoC 2026\] Modernizing Haiku's Bluetooth stack: Implementing support for HFP profile - Mid-Term Progress Report DevFeed: [\[GSoC 2026\] Modernizing Haiku's Bluetooth stack: Implementing support for HFP profile - Mid-Term Progress Report]() Original publisher: [Read original article]() Author: vighnesh-sawant Published: 2026-07-15T14:32:12Z Content type: article Language: en Sources: [Haiku Project]() Topics: [Bluetooth](), [Protocol (disambiguation)](), [systems](), [real-time](), [Streaming](), [USB](), [Kernel](), [interface]() Tags: [api](), [bluetooth](), [driver](), [gsoc](), [haiku](), [implementing](), [kernel](), [modernizing](), [progress-report](), [protocol](), [real-time](), [report](), [software](), [streaming](), [usb]() ### AI overview A GSoC 2026 progress report on modernizing Haiku's Bluetooth stack by adding groundwork for the Hands-Free Profile. Completed work includes isochronous USB endpoint support, SCO handling, kernel hooks, and SCO and RFCOMM protocol implementations. Planned work covers SPP, SDP, and the remaining HFP functionality. ### Source excerpt Introduction Hello again! It has been a fun journey since the beginning of GSoC. My project focuses on modernizing Haiku's Bluetooth stack, specifically adding support for the Hands-Free Profile (HFP). HFP is a profile that allows operating systems to interact with Bluetooth audio devices, such as headsets, for two-way voice calls and audio streaming. Today, I'll be sharing a progress report on the work I have completed till now, and will outline my plans for the remainder of the project. Progress So Far A significant portion of my work has been dedicated to laying the groundwork for the HFP profile. Because Haiku's Bluetooth stack previously lacked the necessary transport layers for real-time audio, I had to implement several underlying protocols. Here is a breakdown of the changes I've made: USB and Driver Support (Isochronous Endpoints): I started off by adding support for isochronous USB endpoints to the h2generic Bluetooth driver. Isochronous transfers are critical because they guarantee bandwidth and timely delivery of data, which is a requirement for streaming real-time audio. Following this, I implemented SCO (Synchronous Connection-Oriented) handling within h2transactions, along with the proper scheduling mechanism.. Kernel Hooks: I added the necessary hooks for SCO and HCI (Host Controller Interface) commands. Protocol Implementations (SCO and RFCOMM): I successfully added the core implementations for both the SCO and RFCOMM protocols. RFCOMM provides an emulated serial interface over L2CAP. It serves as the control channel for many higher-level profiles, including HFP. SCO handles the actual low-latency audio transmission needed for voice calls. What's Next? Short-term Goals: Serial Port Profile (SPP) The Serial Port Profile sits on top of RFCOMM and provides a standard way to send and receive data. Implement SPP API: I will be implementing the JSR82 API methods for SPP in the Bluetooth kit. Implementing the Hands-Free Profile (HFP) The remaining time wil ## Agent Client Protocol (ACP) Adoption Across Editors and Coding Agents DevFeed: [Agent Client Protocol (ACP) Adoption Across Editors and Coding Agents]() Original publisher: [Read original article]() Author: Franciska Dethlefsen Published: 2025-10-02T00:00:00Z Content type: article Language: en Sources: [Zed Industries - Blog]() Topics: [Protocol (disambiguation)](), [agentic-coding](), [Neovim](), [Large Language Model](), [codex]() Tags: [agentic-coding](), [agents](), [coding](), [community](), [llm](), [progress-report](), [protocol](), [report](), [sdk]() ### AI overview Zed reports growing adoption of the Agent Client Protocol (ACP) across editors and coding agents.

Solve the riddle! Housekeeping We're proud to announce that starting this month all our community services, including this very website you're currently visiting, are all running on our PINE64 cluster of 24x ROCKPro64 single board computers. The process of migrating services to the cluster began on June 5 and finished on the 10th without any major dowtimes or hiccups. As of right now the cluster hosts the main PINE64 website, the Wiki, forum, IRC server (and chat bridge) as well as all our Matrix channels. To our knowledge we're the only organization in this neck of the woods to dogfood hardware in this way. I like when things speak for themselves, and so I hope and trust that this is a testimony to our faith in our own hardware. I know many of you are very keen to learn more about the cluster, so I already ha ## September Update: The PinePhone is real & shipping soon DevFeed: [September Update: The PinePhone is real & shipping soon]() Original publisher: [Read original article]() Published: 2019-09-05T00:00:00Z Content type: news Language: en Sources: [Community blog on PINE64]() Topics: [Pinephone](), [Hardware](), [Linux](), [Mobile](), [Development]() Tags: [github](), [gitlab](), [hardware](), [linux](), [mobile](), [pinebook-pro](), [pinephone](), [progress-report](), [projects](), [release](), [software](), [update]() ### AI overview PINE64 reports that PinePhone prototypes completed testing and that a small developer batch has entered production, with shipping to developers planned for September 2019.
