And part of this HSP/HFP implementation is of course needed parsing and interpreting some of AT commands. Look into my design and API proposal. Current daemons which provides AT parsing (like ofono or modem manager) are not suitable for for whole HSP and HFP profiles with all those extensions (like all possible ways for reporting battery level), so for HFP is needed some of custom AT parser. > That said one > simpler way to resolve all of this is to maintain a plugin to > bluetoothd that way HSP/HFP becomes native again, that can either be > maintained in the tree or out of the tree. I do not see how could just plain plugin for bluez without AT parser could help. This seems to just complicate whole implementation. I already implemented prototype implementation of hsphfpd to see how complicated it is and what is needed... So if bluez daemon is not the right place for hsphpfd, it would be separate daemon outside of bluez. -- Pali Rohár pali.ro...@gmail.com ___ pulseaudio-discuss mailing list pulseaudio-discuss@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss

People certainly have written such software, but I'm not aware of anything that would be easy to adopt. People have generally opted for creating a policy module that interfaces with some external policy daemon. In practice they have forked PulseAudio, becaues there's no stable module API, so the modules need to be built together with PulseAudio (or at least PulseAudio needs to be patched to install the internal headers). Nokia used a policy module + policy daemon with the Maemo and Meego phones, and Sailfish OS inherited that (I don't know if they're still using the same system). Intel created the Murphy policy daemon for automotive IVI systems and that too had an associated PulseAudio module. I think I've seen a custom policy module also in Ubuntu (I don't know if it's used outside their phone distro). -- Tanu https://www.patreon.com/tanuk https://liberapay.com/tanuk ___ pulseaudio-discuss mailing list pulseaudio-discuss@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss
