Hello, I use * Debian Jessie/Experimental * kernel 3.16 * pulseaudio 5.99-2 * bluez 5.27 when I connect my Android4.4-based smartphone to PC via bluetooth, I get A2DP profile only, not HSP/HFP Pulseaudio debug log contains this lines: D: [pulseaudio] bluez5-util.c: Adapter: /org/bluez/hci0 D: [pulseaudio] bluez5-util.c: Unknown interface org.freedesktop.DBus.Properties found, skipping D: [pulseaudio] bluez5-util.c: Unknown interface org.bluez.MediaControl1 found, skipping D: [pulseaudio] backend-native.c: Bluetooth Headset Backend API support using the native backend D: [pulseaudio] backend-native.c: Registering Profile /Profile/HSPAGProfile then there is no message from backend-native.c source even I connect my smartphone. Bluez debug log contains follow info after pulseaudio started: bluetoothd[19688]: src/profile.c:ext_device_probe() Headset Voice gateway probed with UUID 00001108-0000-1000-8000-00805f9b34fb bluetoothd[19688]: src/service.c:change_state() 0xadd800: device 00:02:5B:00:13:5B profile Headset Voice gateway state changed: unavailable -> disconnected (0) bluetoothd[19688]: src/adapter.c:dev_class_changed_callback() Class: 0x180104 bluetoothd[19688]: src/attrib-server.c:attrib_db_update() handle=0x0008 bluetoothd[19688]: src/adapter.c:dev_class_changed_callback() Class: 0x1c0104 bluetoothd[19688]: src/attrib-server.c:attrib_db_update() handle=0x0008 then, when I connect my smartphone, bluez writes this: bluetoothd[19688]: src/device.c:connect_profiles() /org/bluez/hci0/dev_00_02_5B_00_13_5B (all), client :1.206 bluetoothd[19688]: src/service.c:btd_service_ref() 0xad31d0: ref=2 bluetoothd[19688]: src/service.c:change_state() 0xad31d0: device 00:02:5B:00:13:5B profile Headset Voice gateway state changed: disconnected -> connecting (0) bluetoothd[19688]: src/adapter.c:connect_failed_callback() hci0 00:02:5B:00:13:5B status 4 bluetoothd[19688]: plugins/policy.c:conn_fail_cb() status 4 bluetoothd[19688]: src/adapter.c:bonding_attempt_complete() hci0 bdaddr 00:02:5B:00:13:5B type 0 status 0x4 bluetoothd[19688]: src/device.c:device_bonding_complete() bonding (nil) status 0x04 bluetoothd[19688]: src/device.c:device_bonding_failed() status 4 bluetoothd[19688]: src/adapter.c:resume_discovery() bluetoothd[19688]: Unable to get Headset Voice gateway SDP record: Host is down bluetoothd[19688]: src/service.c:change_state() 0xad31d0: device 00:02:5B:00:13:5B profile Headset Voice gateway state changed: connecting -> disconnected (-112) bluetoothd[19688]: src/device.c:device_profile_connected() Headset Voice gateway Host is down (112) bluetoothd[19688]: src/device.c:device_profile_connected() returning response to :1.206 But with ofono backend (without any other changes), my smartphone connects via HSP/HFP and can use PC as headset device perfectly.
I need to confirm this still, but it might be that the native backend simply doesn't have implementation for the headset role, meaning that your use case isn't supported. If so, then someone should implement the headset role support, but I don't know who that will be... At least this needs to be added to the release notes, since this is an important shortcoming.
Yes, this is known, and hopefully we can try to have this for 7.0.
