Hello Lemmy,
I am the author of bluetuith, an open-source TUI-based bluetooth manager for Linux only. I have been working on this project for over 2 years on and off, and I was wondering about extending support to other platforms as well.
To begin with, the Bluetooth Classic (BR/EDR) implementation on Linux is fairly standardized (via bluez APIs), but on other platforms, especially windows, Bluetooth APIs are finicky, and tricky to deal with, and also there is no standardized management in general.
I would like to start creating a centralized Bluetooth server or a daemon for other platforms (natively maybe), mainly Windows and Linux, which can expose relevant APIs so that clients can use them to handle Bluetooth-based operations. I know this is quite an uphill task, but I would like suggestions on how to implement it, or if anyone has a better idea, please do suggest that as well.
To summarize, my current plan is this:
- Create bluetooth servers natively for each platform, utilizing the platform's proven APIs to handle bluetooth-based functions and expose a standard API to clients
- Adapt clients to use said APIs provided by the daemons to allow the user to control bluetooth in general.
For the server implementation (mainly to other platforms), I will require contributors, so contributors are highly welcome to be involved in the project. I am in the process of securing an NLnet grant to invest into this project and mainly pay contributors to implement this platform-wise (the proposal has been accepted, and the negotiation call will be hosted in a few weeks, more details about this can be further published if anyone has questions about this. If contributors are confirmed, maybe the budget could be adjusted as well).
I apologize if the post is naive or does not fit this community's guidelines, and if it doesn't, a comment on where to redirect this question would be great.
Constructive feedback is appreciated. Thank you.
Note: By Bluetooth operations, I mainly mean Bluetooth Classic based operations.
It's not about the size of the stacks IMO, the Bluetooth stack is notoriously difficult to interact with since the implementation varies wildly across different platforms and maybe architectures, and communicating with those different stacks is difficult, in a way. And within each stack you may find many features that are sparsely or not documented at all.
Just saying, but if it were easy, cross-platform libraries would have been developed long ago, but to this day most libraries have implementations where some functions are either finicky or not implemented. In no way am I trying to criticize the authors of those libraries, IMO it is a commendable achievement that they have understood the standard and the different stacks and have attempted make it cross-platform friendly and easy-to-use, but that's just the state of Bluetooth these days.
That does go a long way towards explaining why there are so many Bluetooth vulnerabilities, thanks for the info. Looking at the list of Bluetooth protocols wiki page gives me a headache. Surely there is a better standard, and I see things like HaLow, ZigBee, Z-Wave and other custom protocols, but it seems like there should be a very cleanly well-documented alternative to do the basics that everyone expects BT to do. This, coming from a total noob, speaking completely out of my anus. I just know that as a BT user, it's a crapshoot whether there will be major audio delay, and pause/play actually worked, that's if pairing works in the first place. But if something did come along I wonder if there would even be adoption among consumer devices.
