    You should be able to set it with dbus-send, and if i'm reading the documentation correctly the once it's set then it will work for all communications.

    I tried that, but no go.
    dbus-send is throwing all sort of errors maybe I'm using the wrong syntax

    Hi,

    I installed HFP for Linux in Ubuntu machine, it is able to connect to my cell phone, but when I click on “Connect Audio” button on the GUI, I get “Failed to open primary sound card” error, but the Feedback Test in Audio Device page passed (with some delay).

    I enabled alsa during configure option.

    Can u please assist me on this issue?

    With Best Regards,
    Harsha

    I really want to use this great tool and therefore I created a PKGBUILD (Install script) for the ArchLinux user-repository: https://aur.archlinux.org/packages.php?ID=55457
    Installation works fine and I'm even able to find different phones in a public crowded area. Unfortunately, my Android phone doesn't seem to offer the concrete service hfp is searching for, because on the phone, I turned Bluetooth on, paired the device with my laptop but still no success. Is it possible to "unfilter" the device class of the Android phone, so that it appears on the list? sdptool browse shows that there are two audio gateways.

    Thank you for any support in advance.

    BlueZ already supports asynchronous SDP after 3.5

    Hi Sam,

    Great Job! Have you stopped developing yet?
    Just want to you know, the BlueZ already supported asynchronous SDP after 3.5. You may have interested to remove the "helper thread" in libhfp.

    Regards,

    Seems that the Feedback Test in Audio Device is a bit buggy. Even if you think you've passed it ("with some delay"), it might be not the case.
    I've managed to make hfconsole work on Ubuntu 11.10 x86_64 with kernel 3.0.0-17 and Broadcom Corp. Bluetooth Controller (0a5c:217f):
    1. [ -f /lib/libudev.so.0 ] || sudo ln -s /lib/x86_64-linux-gnu/libudev.so.0 /lib/libudev.so.0
    You can find the actual path for libudev.so.0 (subdirectory of x86_64-linux-gnu in my case) with the command "locate libudev.so.0".
    2. sudo hciconfig hci0 scomtu 64:8
    3. hfconsole
    4. Settings->Audio Device->
    Driver: ALSA
    Device: pulse
    [v]Packet Interval: 1000ms
    [ ]Jitter Window
    [v]Output Buffer: 1000ms

    Although the voice delays for ~2 seconds. You may try do disable the output buffer and reduce the packet interval. This will reduce the delays. Log of hfconfig says that the actual delay was ~130 ms.
