Hi, I've googled a lot to find any hint on getting a bluetooth connection from my tablet (iPad and Android) to pulsaudio running on raspberry pi, but up to now without success. My Raspberry PI system: Linux Kernel 4.1.19-4-ARCH bluez 5.37-2 pulseaudio 8.0-3 All packets most actual offical versions according to archlinuxarm distribution. ---------------------------------------------------------- Trying to connect with bluetoothctl yields: $ connect D8:90:E8:A5:95:86 Attempting to connect to D8:90:E8:A5:95:86 Failed to connect: org.bluez.Error.Failed ---------------------------------------------------------- No message in syslog, the only hint I can find is running bluetooth-daemon in debugging mode, which indicates that the a2dp-plugin was loaded (at least no error message), but the "protocol is not available" (without additional information). Lots of similar messages of this type can be found with google, but up to now I didn't find a hint what's going wrong. here the bluetooth-debug with a2dp relevant output: ---------------------------------------------------------- bluetoothd[6853]: Bluetooth daemon 5.37 bluetoothd[6853]: src/main.c:parse_config() parsing main.conf bluetoothd[6853]: src/plugin.c:add_plugin() Loading sap plugin bluetoothd[6853]: src/plugin.c:add_plugin() Loading a2dp plugin bluetoothd[6853]: src/plugin.c:add_plugin() Loading avrcp plugin bluetoothd[6853]: src/plugin.c:add_plugin() Loading network plugin bluetoothd[6853]: src/gatt-database.c:gatt_db_service_added() GATT Service added to local database bluetoothd[6853]: profiles/audio/a2dp.c:media_server_probe() path /org/bluez/hci0 bluetoothd[6853]: plugins/hostname.c:hostname_probe() bluetoothd[6853]: src/adapter.c:add_uuid() sending add uuid command for index 0 bluetoothd[6853]: profiles/audio/a2dp.c:a2dp_sink_server_probe() path /org/bluez/hci0 bluetoothd[6853]: profiles/audio/a2dp.c:a2dp_source_server_probe() path /org/bluez/hci0 bluetoothd[6853]: profiles/sap/manager.c:sap_server_probe() path /org/bluez/hci0 bluetoothd[6853]: Sap driver initialization failed. bluetoothd[6853]: sap-server: Operation not permitted (1) bluetoothd[6853]: src/service.c:change_state() 0x4eb178: device D8:90:E8:A5:95:86 profile audio-avrcp-target state changed: unavailable -> disconnected (0) bluetoothd[6853]: profiles/audio/a2dp.c:a2dp_source_probe() path /org/bluez/hci0/dev_D8_90_E8_A5_95_86 bluetoothd[6853]: profiles/audio/source.c:source_init() /org/bluez/hci0/dev_D8_90_E8_A5_95_86 bluetoothd[6853]: src/service.c:btd_service_ref() 0x4ec020: ref=2 bluetoothd[6853]: src/service.c:change_state() 0x4ec020: device D8:90:E8:A5:95:86 profile a2dp-source state changed: unavailable -> disconnected (0) bluetoothd[6853]: src/device.c:device_probe_profiles() Probing profiles for device 20:7D:74:94:30:76 bluetoothd[6853]: src/service.c:change_state() 0x4e2480: device 20:7D:74:94:30:76 profile audio-avrcp-target state changed: unavailable -> disconnected (0) bluetoothd[6853]: profiles/audio/a2dp.c:a2dp_source_probe() path /org/bluez/hci0/dev_20_7D_74_94_30_76 bluetoothd[6853]: profiles/audio/source.c:source_init() /org/bluez/hci0/dev_20_7D_74_94_30_76 bluetoothd[6853]: src/service.c:btd_service_ref() 0x4ebc88: ref=2 bluetoothd[6853]: src/service.c:change_state() 0x4ebc88: device 20:7D:74:94:30:76 profile a2dp-source state changed: unavailable -> disconnected (0) bluetoothd[6853]: src/adapter.c:adapter_service_insert() /org/bluez/hci0 bluetoothd[6853]: src/adapter.c:adapter_start() adapter /org/bluez/hci0 has been enabled bluetoothd[6853]: src/device.c:connect_profiles() /org/bluez/hci0/dev_D8_90_E8_A5_95_86 (all), client :1.309 bluetoothd[6853]: profiles/audio/a2dp.c:a2dp_source_connect() path /org/bluez/hci0/dev_D8_90_E8_A5_95_86 bluetoothd[6853]: a2dp-source profile connect failed for D8:90:E8:A5:95:86: Protocol not available ---------------------------------------------------------- Thanks for any help HP
