I am trying to implement a HFP and a A2DP profile on top of bluez. I did check out the bluez-utils/audio stuff, but I couldn't get it working, so I decided to write my own, and publish it for your review so that you can pull it into bluez if you like it. My primary problem with the current bluez-utils/audio implementation (apart that it's not working for me) is that gstreamer, d-bus is integrated all over the place. I would prefer to implement the HFP and A2DP profiles so that are stand alone, and they can be integrated with d-bus, hal and gstreamer through an API. This would allow us/me to use the profiles not only on a desktop PC but also in an embedded environment where d-bus or gstreamer is not an option. The HFP profile is ready, all 4 state machines (main hfp, service connection, incoming call, outgoing call) work properly and one can accept, reject and make calls both from the Device or from the PC. For HFP audio io I use ALSA. However for the A2DP, I failed to get up the L2CAP Transport Layer so I cannot get any audio out of L2CAP socket. My setup is the following: Device: a2dp capable phone (SonyEricsson W850i and an MDA with windows mobile) PC: usb bluetooth dongle with latest bluez stack running on the 2.6.20-2936.fc7xen kernel I implemented the L2CAP signaling layer, and the Device hooks up nicely with the PC and starts streaming the audio data. I can see the audio data with hcidump: > ACL data: handle 1 flags 0x02 dlen 665 L2CAP(d): cid 0x0041 len 661 [psm 25] AVDTP(m): ver 2 cc 0 pt 1 seqn 726 time 9478796 ssrc 1 But I don't know how to extract this data through the L2CAP socket which I opened for signaling. Is there some socket option that I need to set up in order to get the audio data? Or do I need to set up an other socket once the AVDTP state machine enters into OPEN state? Once this problem is solved, it would take me about 2 weeks to publish both, fully featured profiles. Any help is appreciated!
