The post discusses Bluetooth proxy range, regulatory constraints, testing considerations, and the use of NFC stickers for maintenance tracking, while reflecting on using Codex during the project. ### Source excerpt Fuck1 it, we're doing consumer hardware for ourselves now and getting fucked by economies of scale, I guess. This all started with me buying some Olimex Bluetooth proxies for Home Assistant. Then I started looking at the components and wondering if I could get better range. Now I'm designing boards, displays, and enclosures, and emailing manufacturers because their bezels are enormous. I've ordered the first two boards: a Bluetooth sensor hub and a little maintenance display. I've been working on this in Codex, and this post is going to go through what it was good at, where it got stuck or got things wrong, and where I had to step in. Why build this? Honestly, Control4, Savant, and the rest of these fucking systems seem built for rich people who don't know how to turn on their TV and would rather call someone. I want to program the fucking thing. Control4 puts HomeKit integration in its paid Connect tier.2 Why am I paying a recurring fee to connect things I already bought? I don't want to call a Control4 or Savant dealer, either, just because I want to change how something works. Give me API access or give me death. Source works too. I'll pick the hardware and connect it to Home Assistant, HomeKit, or my own code. If I want another sensor or some weird maintenance reminder, I can write that. It's my fucking house.31 Back to the Bluetooth proxies With a Bluetooth proxy, I can put the BLE radio near the sensors and get back to Home Assistant over the network.4 The machine running Home Assistant doesn't have to be within range of every sensor. When I mentioned my plans to Paul (paultag) over Slack, he pointed out that Olimex might be constrained by what the FCC allows, not just the components it picked. A radio supporting more transmit power doesn't mean you can use all of it.5 I hadn't thought about that. These are boards for my house. I'm not selling them. Fuck it, I'll build them and test them. I still have to measure the range; a bigger number on the radio's datash ## GSoC 2026 Final Report | Modernizing Haiku's Bluetooth Stack: HID Profile Implementation DevFeed: [GSoC 2026 Final Report | Modernizing Haiku's Bluetooth Stack: HID Profile Implementation]() Original publisher: [Read original article]() Author: mohammedrattia Published: 2026-09-06T12:00:24Z Content type: article Language: en Sources: [Haiku Project]() Topics: [Bluetooth](), [implementation]() Tags: [bluetooth](), [drivers](), [gsoc](), [gsoc2026](), [haiku](), [hid](), [implementation](), [input](), [report](), [software]() ### AI overview This final GSoC 2026 report describes work to improve Haiku's Bluetooth stack and implement the HID profile. It reports that Bluetooth mice and keyboards are functioning and that the core stack is ready for additional profiles, while noting that Low Energy Bluetooth remains unimplemented and further work is needed. ### Source excerpt Hello! Finally, GSoC is done for me. This is the final report for my project. The project was focused on improving the Bluetooth stack and making it useful. Hopefully, the Bluetooth stack is now in a much better state than before GSoC 2026. It still needs much work to be fully developed. However, currently Bluetooth mice and keyboards are functioning. In addition, the core of the stack is ready for implementing other profiles. This report will include the following: Project Overview What I Did Future Work Conclusion Project Overview The State of Bluetooth on Haiku Before GSoC 2026 Although the Bluetooth stack was outdated (based on version 2.0 and 2.1 of Bluetooth) before GSoC, it contained many core components that helped us focus less on starting from scratch and more on making the already built stack useful. However, that's true only for BR/EDR (Basic Rate / Enhanced Data Rate) Bluetooth, not Low Energy Bluetooth, which isn't implemented yet in Haiku. The BR/EDR Bluetooth core stack is divided into several core modules that provide services for the Bluetooth profiles, which in turn provide services to users like human interface devices, audio, file transfer, etc. Some of those core modules and their state in Haiku are: L2CAP: Functional, but needed some fixes. HCI (Host Controller Interface): Functional, but on an old Bluetooth version, as stated above. Transfer Layer (h2generic): Functional, but required further extension to cover vendor-specific devices. Preferences Application: Functional, but it lacked some features, such as changing the Bluetooth friendly name, canceling inquiry and pairing, and adding devices to a block list. Security Manager: Not complete; it's blended into the Bluetooth Server, and most of its functions were missing. Service Discovery Protocol (SDP): Not implemented. The state mentioned above meant the Bluetooth stack couldn't yet offer much practical functionality to users, because none of the Bluetooth profiles were implemented.

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 ## ESPHome 2026.8.0: Bluetooth on more chips than ever DevFeed: [ESPHome 2026.8.0: Bluetooth on more chips than ever]() Original publisher: [Read original article]() Author: Jesse Hills Published: 2026-08-19T00:00:00Z Content type: release Language: en Sources: [ESPHome - Smart Home Made Simple - Blog]() Topics: [esphome](), [Bluetooth](), [networking](), [Raspberry Pi](), [ESP32](), [Ethernet](), [Modbus](), [ESP8266](), [Lvgl]() Tags: [bluetooth](), [esp32](), [esp8266](), [esphome](), [ethernet](), [lvgl](), [modbus](), [networking](), [raspberry-pi](), [release](), [releases]() ### AI overview ESPHome 2026.8.0 expands Bluetooth support beyond ESP32 through a platform-neutral BLE layer, adds Bluetooth Proxy support for more chips and Raspberry Pi Pico W, and introduces faster builds, combined Ethernet and WiFi configuration, Modbus changes, OTA signature verification, and other device and builder improvements. ### Source excerpt ESPHome 2026.8.0 brings Bluetooth to more chips, dramatically faster builds, Ethernet and WiFi together, a major Modbus overhaul, and more. ## Haiku Activity & Contract Report, July 2026 DevFeed: [Haiku Activity & Contract Report, July 2026]() Original publisher: [Read original article]() Author: waddlesplash Published: 2026-08-14T16:00:00Z Content type: news Language: en Sources: [Haiku Project]() Topics: [App](), [GUI](), [Bluetooth](), [x86](), [Font](), [pixel](), [Terminal](), [Network]() Tags: [2026](), [activity-report](), [app](), [bluetooth](), [contractor](), [gui](), [network](), [pixel](), [report](), [terminal](), [x86]() ### AI overview Haiku's July 2026 activity and contract report covers revisions hrev59821 through hrev59921.
