Hi everybody,

i’m a long time Debian user and, while i’ve always loved the Linux experience, the bluetooth side of things was always a little bit… painful.

Lately, i’ve been digging on how bluetooth on Linux works (i knew about BlueZ, but i didn’t know about HCI sockets, standard protocols for bluetooth controllers, …). Seeing how Android manages to work fine with bluetooth (yes, i know, money and company support, blah blah blah), i was thinking about re-writing the bluetooth daemon, in order to be modern, modular, safe (written in Rust), stable and retro-compatible (exposes the same D-Bus APIs as BlueZ) I already found some documents about HCI socket in Linux, HCI communication with bluetooth controllers, HID standards for Bluetooth, etc…

My questions are:

  • is this a good idea?
  • does somebody want to collaborate?

Thanks for reading.

EDIT: The repository is https://github.com/djtech-dev/reblued but at the moment is pretty much empty, just the project’s skeleton, license, README and disussions for collaborators.

    Thanks for your reply; i won’t work with firmware-level aspects of the stack, as my plan is to write the userspace daemon, while keeping the kernel-levels modules identical and to communicate to them via HCI sockets, as they are implemented by Linux and with them I can talk directly to the bluetooth controllers.

    I’ll check out Android’s project and double-check for security vulnerabilities in older version of the protocols tho, so thank you again for replying.
