Not following you on this one, oFono is intended for telephony functionality and afaik it could parse battery, etc. Also would your daemon include such functionality or you are to combine that with oFono? I do appreciate the effort you have put into the SBC modes and codec support but Im afraid you are going to experience some real pain to maintain such a system all in your own, there are a lot of features being exposed via AT commands and we risk to have yet another daemon that just do parts of them until the next person comes with a different use case and we are back to square one. > > 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.

Well the exactly the same thing with yet another daemon, we obviously will need an AT parser, but the nice thing of being a native plugin is that it can detect if another entity register for HSP/HFP and disable itself (or have a policy to control that), the implementation can be exactly what you have but without the extra rounds trips involved to communicate back and forth with your daemon, so it is pretty straight forward in terms o implementation. > So if bluez daemon is not the right place for hsphpfd, it would be > separate daemon outside of bluez. > > -- > Pali Rohár > pali.rohar@xxxxxxxxx -- Luiz Augusto von Dentz _______________________________________________ pulseaudio-discuss mailing list pulseaudio-discuss@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss
