HFP for Linux Bluetooth Hands Free

**samr7** · 10-18-2008, 04:19 AM

I'm trying to put together support for Bluetooth Hands-Free Profile on Linux. We all know what a mess Bluetooth HFP is on Windows, and the lengths that some will go through to get it to work despite the fragmented infrastructure. Fortunately, on Linux, we are blessed with a single good standard of BlueZ. One would think that it could only be easier to create a good HFP implementation on Linux. I hope to prove that to be the case.

Recently posted on SourceForge, in the subversion repository:

http://nohands.sourceforge.net/

This package aims to support a variety of relevant standards:

Bluetooth HFP 1.5, although presently only tested with Motorola handsets
ALSA and OSS sound drivers
libspeexdsp for noise reduction/echo cancelation
D-Bus for environmental integration and external control
PyGTK and Qt GUIs

With luck, this package will make its humble debut as a plugin for tripzero's nGhost 2.1 platform, due to be released within a month.

Any code/testing/interest is appreciated!

Wow.. I give all my support, but i'm not a great programmer.. i hope that someone join this project, because I was looking for this feature for so much time...

Thanks Malo, I hope so too.

You don't need to be able to program to help. If you can build it on your machine, or even try to build it and tell me why it won't build, this helps. If you can get as far as to test it with your phone, that helps a lot more.

Hi Punky. What do you mean by auto-connection?

Auto-connection of _known_ devices, at least, is an implemented feature! It has also been tweaked to work following resume-from-hibernate, so if you leave hfconsole running with the phone attached when hibernating the PC, the phone is automatically re-attached when the PC is powered back on. It's a quick process too.

One of these days I'll post an action video on YouTube, but as soon as the user interface components are better integrated with nGhost.

I'll give it a go building this on my setup (Gentoo AMD64 2.6.27), and report back if it works or not

**update**

Compiled fine, but...

Code:

** OpLatency: primary open took 40ms
Create SCO socket: 93
Bluetooth Failure, hub shut down
Create SCO socket: 93

Bluetooth just refuses to work full stop...

Hm. Is your kernel built with SCO socket support? Gotta have that for the audio to work.

The error reporting is a bit lame right now, I'll see about having it make this condition more obvious.
