Hi Lennart, If I understand you right, my handsfree unit could only receive HFP/HSP audio from the mobile phone. The handsfree unit could not send any audio to the mobile. Right? I'll definitely ping the Bluez guys (again). Thanks, Burkhard <div class="gmail_quote">2009/12/28 Lennart Poettering <<a href="mailto:lennart@poettering.net">lennart@poettering.net</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div class="im">On Mon, 28.12.09 13:08, Burkhard Stubert (<a href="mailto:burkhard.stubert@googlemail.com">burkhard.stubert@googlemail.com</a>) wrote: > Hi chaps, > > I am trying to build a demo for a handsfree unit (HFU) in a car.

However I know that someone mentioned that Intel (?) wrote some code to allow PA/Bluez to act as HFP/HSP device, too, but that code seems not to be available publically. It might be a good idea to ping the Bluez folks about this as the core HFP/HSP/A2DP implementations comes from them, on which PA then builds.
