[RFC 00/24] Add support for Bluetooth HFP Handsfree Unit implemented in oFono

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Jo?o Paulo Rechi Vita <jprvita@xxxxxxxxxxxxx>

The Bluetooth Handsfree Profile (HFP), role Hansfree (HF), is used when we want
to work as a Hands-free unit to control audio calls performed by an Audio
Gateway (AG), generally a cellular phone.

After the release of BlueZ 5, which added support for external profiles, the
HFP implementation has been moved out of BlueZ and implemented in oFono. A new
D-Bus API has been defined to enable the IPC between oFono's Handsfree Audio
Manager, which takes care of the Bluetooth HFP modems, and a Handsfree Audio
Agent, which in our particular case is PulseAudio.

This series implements support for the HFP HF role in the card representing the
Bluetooth device through a new card profile, "Handsfree Audio Gateway", which
is the name of the role performed by the remote device.

At the moment HFP up to 1.6 is supported, but without wideband speech. Wideband
speech support work is in progress. Also, this series works with kernels < 3.8,
since handling of defer setup of SCO sockets is also a WIP.

This series is based on top of Mikel Astiz' work to add BlueZ 5 support to the
bluetooth modules.
