Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii"; format=flowed Sender: linux-bluetooth-owner@vger.kernel.org List-ID: Hello, I want to make use of the answer-button of a bt-headset in my linux app but it just works in HSP, not in HFP mode (I have been playing around with this since bluez 4.3x, but the error stayed). I tried this in C and in python and I get the AnswerRequested-signal only when "HFP=false" is set in /etc/bluetooth/audio.conf. Tests with three different headsets and on two different computers (Ubuntu laptop and debian lenny desktop PC) showed the exact same behaviour. HSP would be enough for me, but when HFP is true, the range of the headsets increases from like 5 to 20 meters until the sound gets choppy (although the headsets are class2, but the adapter is class1), and I would like to make use of the extended range. Is this normal or do I have misconfigured something (for both the range and the answer-signal)? Thanks, Peter P.S.: I still have the error from last week with getting speakergain of the headsets in C, any help is appreciated.
