Hi Leonid, hi to all, I know this patch is not perfect and still has some issues. But since there is currently no alternative, I would like to use it on my iMX31 platform. And if afterwards I can help with some improvements, it's worthy. In the meantime, I have to dive in your code, the bluez code and in the buetooth specifications. Since I'm not an expert, neither for bluetooth and bluez, neither for sound, I would earn some time if I could get some answers already. I installed the "Gateway Profile" patch on BlueZ 4.28 (with some minor corrections for the compilation). 1. First issue, only the "Handsfree" service is exported : $ sdptool browse local Browsing FF:FF:FF:00:00:00 ... Service Name: Hands-free Service RecHandle: 0x10000 Service Class ID List: "Handsfree" (0x111e) "Generic Audio" (0x1203) Protocol Descriptor List: "L2CAP" (0x0100) "RFCOMM" (0x0003) Channel: 6 Profile Descriptor List: "Handsfree" (0x111e) Version: 0x0100 Here is the audio.conf file I use : [General] Master=true Enable=Gateway Disable=Headset;Sink;Source;Control SCORouting=PCM [Headset] HFP=true MaxConnected=1 I certainly miss something in my configuration in order to also get the Headset service exported. 2. Second issue, any attempt to connect the handsfree service from a mobile failed. The mobile ends in the paired state, but the handsfree device connection failed. Here is the full (annotated) ouput of the bluetoothd daemon. bluetoothd[1772]: Bluetooth daemon bluetoothd[1772]: Enabling debug information bluetoothd[1772]: parsing main.conf bluetoothd[1772]: discovto=0 bluetoothd[1772]: pairto=0 bluetoothd[1772]: pageto=8192 bluetoothd[1772]: name=%h-%d bluetoothd[1772]: class=0x000100 bluetoothd[1772]: inqmode=0 bluetoothd[1772]: Key file does not have key 'DeviceID' bluetoothd[1772]: Starting SDP server bluetoothd[1772]: Loading plugins /usr/lib/bluetooth/plugins bluetoothd[1772]: register_interface: path /org/bluez/1772/any bluetoothd[1772]: Registered interface org.bluez.Service on path /org/bluez/1772/any bluetoothd[1772]: Unix socket created: 10 bluetoothd[1772]: HCI dev 0 registered bluetoothd[1772]: child 1773 forked bluetoothd[1772]: HCI dev 0 already up bluetoothd[1772]: Starting security manager 0 bluetoothd[1772]: register_interface: path /org/bluez/1772/hci0 bluetoothd[1772]: Registered interface org.bluez.Service on path /org/bluez/1772/hci0 bluetoothd[1772]: gateway_server_probe: path /org/bluez/1772/hci0 bluetoothd[1772]: Adding record with handle 0x10000 bluetoothd[1772]: Record pattern UUID 00000003-0000-1000-8000-00805f9 bluetoothd[1772]: Record pattern UUID 00000100-0000-1000-8000-00805f9 bluetoothd[1772]: Record pattern UUID 00001002-0000-1000-8000-00805f9 bluetoothd[1772]: Record pattern UUID 0000111e-0000-1000-8000-00805f9 bluetoothd[1772]: Record pattern UUID 00001203-0000-1000-8000-00805f9 bluetoothd[1772]: proxy_probe: path /org/bluez/1772/hci0 bluetoothd[1772]: Registered interface org.bluez.SerialProxyManager on path /org/bluez/1772/hci0 bluetoothd[1772]: Creating device /org/bluez/1772/hci0/dev_00_0E_ED_01_DA_66 bluetoothd[1772]: Probe drivers for /org/bluez/1772/hci0/dev_00_0E_ED_01_DA_66 bluetoothd[1772]: adapter_get_device(00:0E:ED:01:DA:66) bluetoothd[1772]: audio handle_uuid: server not enabled for 00001112-0000-1000-8000-00805F9B34FB (0x1112) bluetoothd[1772]: Found Handsfree AG record bluetoothd[1772]: serial_probe: path /org/bluez/1772/hci0/dev_00_0E_ED_01_DA_66: 00000002-0000-1000-8000-0002ee000002 bluetoothd[1772]: Registered interface org.bluez.Serial on path /org/bluez/1772/hci0/dev_00_0E_ED_01_DA_66 bluetoothd[1772]: serial_probe: path /org/bluez/1772/hci0/dev_00_0E_ED_01_DA_66: 00001101-0000-1000-8000-00805f9b34fb bluetoothd[1772]: serial_probe: path /org/bluez/1772/hci0/dev_00_0E_ED_01_DA_66: 00001103-0000-1000-8000-00805f9b34fb bluetoothd[1772]: serial_probe: path /org/bluez/1772/hci0/dev_00_0E_ED_01_DA_66: 00001105-0000-1000-8000-00805f9b34fb bluetoothd[1772]: serial_probe: path /org/bluez/1772/hci0/dev_00_0E_ED_01_DA_66: 00001106-0000-1000-8000-00805f9b34fb bluetoothd[1772]: serial_probe: path /org/bluez/1772/hci0/dev_00_0E_ED_01_DA_66: 00001112-0000-1000-8000-00805F9B34FB bluetoothd[1772]: serial_probe: path /org/bluez/1772/hci0/dev_00_0E_ED_01_DA_66: 0000111f-0000-1000-8000-00805f9b34fb bluetoothd[1772]: serial_probe: path /org/bluez/1772/hci0/dev_00_0E_ED_01_DA_66: 0000112d-0000-1000-8000-00805f9b34fb bluetoothd[1772]: serial_probe: path /org/bluez/1772/hci0/dev_00_0E_ED_01_DA_66: 00005002-0000-1000-8000-0002ee000001 bluetoothd[1772]: Adapter /org/bluez/1772/hci0 has been enabled bluetoothd[1772]: child 1773 exited # Passkey agent started bluetoothd[1772]: Agent registered for hci0 at :1.4:/org/bluez/agent_1782 # Attempt from a mobile (Nokia 6810) to connect the handsfree device bluetoothd[1772]: adapter_get_device(00:0E:ED:01:DA:66) bluetoothd[1772]: adapter_create_device(00:0E:ED:01:DA:66) bluetoothd[1772]: Creating device /org/bluez/1772/hci0/dev_00_0E_ED_01_DA_66 bluetoothd[1772]: pin_code_request (sba=00:02:5B:00:A5:A5, dba=00:0E:ED:01:DA:66) bluetoothd[1772]: adapter_get_device(00:0E:ED:01:DA:66) bluetoothd[1772]: /org/bluez/1772/hci0/dev_00_0E_ED_01_DA_66: requesting agent authentication Agent_message was called!
