I use the adapter Ovislink EVO-BT2-100 (Bluetooth 2.0), headset Motorola H270 (Bluetooth 2.1), Gentoo on Linux kernel 2.6.27.6 (with the driver hci_usb, btusb doesn't pairing) and Bluez 4.26. I have a problem similar to this discussion: http://thread.gmane.org/gmane.linux.bluez.kernel/456 When I start the headset, the pairing process is ok, and the heandset go into sleep/unpairing. bluetoothd[21367]: kernel auth requirements = 0x00 bluetoothd[21367]: stored link key type = 0x00 bluetoothd[21367]: State changed /org/bluez/21367/hci0/dev_00_1A_0E_DA_1F_01: HEADSET_STATE_DISCONNECTED -> HEADSET_STATE_CONNECT_IN_PROGRESS bluetoothd[21367]: authorize request was sent for /org/bluez/21367/hci0/dev_00_1A_0E_DA_1F_01 bluetoothd[21367]: Accepted headset connection from 00:1A:0E:DA:1F:01 for /org/bluez/21367/hci0/dev_00_1A_0E_DA_1F_01 bluetoothd[21367]: telephony-dummy: device 0x7fe033401790 disconnected bluetoothd[21367]: State changed /org/bluez/21367/hci0/dev_00_1A_0E_DA_1F_01: HEADSET_STATE_CONNECT_IN_PROGRESS -> HEADSET_STATE_DISCONNECTED Next when I run the command "arecord -D bluetooth -f S16_LE test.wav" Bluetoothd connect to the headset and start the record. But after 40s the record stop (no file created) and bluetoothd make a connect timed out : bluetoothd[21367]: Audio API: BT_REQUEST <- BT_GET_CAPABILITIES bluetoothd[21367]: Audio API: BT_RESPONSE -> BT_GET_CAPABILITIES bluetoothd[21367]: Audio API: BT_REQUEST <- BT_SET_CONFIGURATION bluetoothd[21367]: config sco - device = 00:1A:0E:DA:1F:01 access_mode = 1 bluetoothd[21367]: /org/bluez/21367/hci0/dev_00_1A_0E_DA_1F_01: Connecting to 00:1A:0E:DA:1F:01 channel 1 bluetoothd[21367]: State changed /org/bluez/21367/hci0/dev_00_1A_0E_DA_1F_01: HEADSET_STATE_DISCONNECTED -> HEADSET_STATE_CONNECT_IN_PROGRESS bluetoothd[21367]: adapter_get_device(00:1A:0E:DA:1F:01) bluetoothd[21367]: link_key_request (sba=00:11:67:C3:00:99, dba=00:1A:0E:DA:1F:01) bluetoothd[21367]: kernel auth requirements = 0x04 bluetoothd[21367]: stored link key type = 0x00 bluetoothd[21367]: /org/bluez/21367/hci0/dev_00_1A_0E_DA_1F_01: Connected to 00:1A:0E:DA:1F:01 bluetoothd[21367]: telephony-dummy: device 0x7fe033401790 connected bluetoothd[21367]: State changed /org/bluez/21367/hci0/dev_00_1A_0E_DA_1F_01: HEADSET_STATE_CONNECT_IN_PROGRESS -> HEADSET_STATE_CONNECTED bluetoothd[21367]: Audio API: BT_RESPONSE -> BT_SET_CONFIGURATION bluetoothd[21367]: Audio API: BT_REQUEST <- BT_START_STREAM bluetoothd[21367]: State changed /org/bluez/21367/hci0/dev_00_1A_0E_DA_1F_01: HEADSET_STATE_CONNECTED -> HEADSET_STATE_PLAY_IN_PROGRESS bluetoothd[21367]: Received AT+VGS=15 bluetoothd[21367]: Received AT+VGM=9 bluetoothd[21367]: connect(): Connection timed out (110) bluetoothd[21367]: Audio API: BT_RESPONSE -> BT_START_STREAM bluetoothd[21367]: Audio API: BT_INDICATION -> BT_NEW_STREAM bluetoothd[21367]: unix_sendmsg_fd: Bad file descriptor(9) bluetoothd[21367]: telephony-dummy: device 0x7fe033401790 disconnected bluetoothd[21367]: State changed /org/bluez/21367/hci0/dev_00_1A_0E_DA_1F_01: HEADSET_STATE_PLAY_IN_PROGRESS -> HEADSET_STATE_DISCONNECTED bluetoothd[21367]: headset_resume_complete: resume failed bluetoothd[21367]: Audio API: BT_ERROR -> BT_START_STREAM bluetoothd[21367]: Unix client disconnected (fd=13) bluetoothd[21367]: No matching connection for handle 2 The Alsa error is: arecord: set_params:1015: Unable to install hw params: ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: 16 CHANNELS: 1 RATE: 8000 .... With Strace I see it's a PF_BLUETOOTH (with ther kernel ??) socket error. Recent Bluez 3.x make the same problem and old crash rfcomm in the kernel. It's only work on Ubuntu Hardy, kernel 2.6.24 bluez 3.26 with "lm accept,master;" and "lp hold,sniff,park;" (not in bluez 4),, but 2.6.24 is a bit old for ext4... Thanks in advance. Regards. Nicolas
