    followup results

    sam,

    Just a followup...the last rev I used (I think it was about r44, can't remember) wasn't working, in that I wasn't even able to pair the phone and laptop at all, so couldn't test anymore, but today I checked out r55 and it started working again (used hfstandalone, initiated pairing via the phone). Audio was working as well- tested my voicemail again and it was working (same breakups when doing something like changing window focus, etc...any kind of system load). Perhaps more interesting, however, was that I made my first live voice call! 6m24sec...both audio output and capture worked... the recipient said they could hear their own voice...I tried changing the echo cancellation delay but it didn't seem to affect it (in hindsight though, maybe I wasn't thinking correctly...does the program have to be restarted or a new call initiated for changes to take effect?). Other change since I last tried is a kernel upgrade to 2.6.28-rc5-git4. Going great here, thanks for your hard work!

    Thumbs up Yay

    Revision 69 is working great here, using an MSI BT/Wifi Combo card (MS-8255 or something similar was the exact model, I think). It works nicely with my 1st gen iPhone, and is able to extract full caller ID information correctly, and can handle not only the basic answering and call control functions, but dialing as well... which is something I didn't think the iPhone would support.

    The only trouble I've run into is the latest BlueZ releases (4.x), as they seem to at least have problems with the 2.6.27 kernel, and will not prompt for the PIN on the computer side of things. I tried upgrading the kernel and replacing various libs and binaries, but only was able to pair after downgrading to the 3.x branch.

    Just a heads up for anyone who runs into that. Aside from the BlueZ problems, though, I haven't had any trouble at all with the nohands package, it pretty much 'just worked' for me.

    Audio quality was so-so... the outgoing sound was a bit muffled but I can't guarantee my microphone wasn't a factor there. Sound coming in was excellent, though.

    As soon as I get the hardware for my carputer, I guarantee it will be part of my setup.

    My sister gave me her v3xx (she just got a Wing) and it seems to work much better and much more consistently than my v3x...although there still seems to be pairing problems when using hfconsole (which just got reworked...looks nice sam!). The phone always states Invalid PIN entered, whether I initiate the pairing from the phone or the computer...but I am never asked for it (I've tried setting up hcid.conf with automatic or ask user for pin settings...I seem to remember there used to be an option to select what command to use for a pin-helper, though that's not there anymore).

    Cheers,
    Jesse

    gtk ui works

    Nevermind my last post, the gtk ui now works quite well...signal strength, battery charge meter and call status all seem to function properly, too! Sam, have you considered porting the qt ui to qt4? I've opened up the ui files in the Qt Designer that comes with qt/KDE 4 and they seem to import pretty clean...they look nice. I tried porting as much of the nohands source as I could to qt4 with the automatic utilities that come with qt4 but of course there are some leftovers that it isn't going to pick up and I know very little C (let alone C++).

    Cheers,
    Jesse

    n800....

    Hi Samr7,

    Ive been looking over your work here and over at internet tablet talk regarding having the hfpd and hfconsole running on a n800.. and for the most part I have it working to the same level of the others (Primary Soundcard Failure) even tho the feedback loop test works fine..... so im thinking of maybe changing things around a little anyways and either just run the hfpd on a laptop and then just have X forward the display of hfconsole to the n800 or is there a way to connect to the dbus/hfpd over the network and I can just knock up a native frontend for then n800?

    Very good work I must say and the most mature of any solutions I can find regarding bluetooth handsfree emulation.

    If I can get this working it would be the final peice of the puzzle regarding my carPC and I can start planning on putting it all together.

    Cheers,

    Lucan

    is it possible to connect to wammu/gammu and hfp at the same time?

    perhaps you can use gammu to integrate the phonebook into your application?

    Samr7, I write a couple email to you about your software.
    I test it on my dell laptop equiped with a
    413c:8103 Dell Computer Corp. Wireless 350 Bluetooth
    I can connect and use my nokia N65, I need only to fix a mic issue.

    I try to build the nGhost plugin, but I have some problem during the plugin loading

    nghost: nhandsfree.cpp:187: bool nghost::NHandsFree::InetConnect(int): Assertion `m_hfpd_state == NHS_HFPD_DISCONNECTED' failed.
    Aborted


    If I comment out the line 187 and rebuild the plugin it start with no problem but I can't see any difference in the main interface, how can I interact with HFP from nghost?

    IlGab, you should use the d-bus API to interact with nghost. i never tried this and i do not know how hard this could be.
    try to join the openice forum. perhaps kev000 is able to help you.

    audio errors in feedback test

    Hi everyone,

    This app looks fantastic! I am having some problems getting it to run though. I am using pulseaudio on my ubuntu dev machine, so maybe that is the problem...

    I have set driver=alsa, device=pulse, packet size=21ms, output buffering=41ms. However I have tried lots of different combinations of packet size and output buffering, they all fail. This is the output I'm getting:

    Code:
    ALSA play state: 2
    ALSA play state: 2
    ALSA rec state: 2
    ALSA rec state: 2
    Config warn: Configured output minimum buffer (328) is less than twice the maximum packet size (336)
    Config warn: Configured output window size (80) is less than twice the maximum packet size (336)
    Pump: packet size = 168
    Pump: bot packet size = 168
    Pump: bot input max fill = 336
    Pump: bot min fill = 336
    Pump: bot max fill = 672
    Pump: top packet size = 168
    Pump: top input max fill = 4294966959
    Pump: top min fill = 0
    Pump: top max fill = 4294967295
    Pump: watchdog timeout = 500

    SoundIoPump Stopped
    Sound card failed: SoundIoPump: bottom output underprocessing
    Audio pump aborted

    After I try that a few times, I inevitably get a segfault.
    Any ideas?

    Humm... I think it's an audio card issue.
    I have the same problem on my new board for the carpc
    The card is
    Code:
    00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)
    On my laptop I have a similar card but rev 01
    Code:
    00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)
    and all works ok...

    I try with the oss driver but no sucess... I still investigate :x
