I am not able to establish SCO connection from PC to headset. My linux kernel version is 2.4.29. I have downloaded the required files from bluetooth-alsa.sf.net and followed the instructions as per the Readme files. To send audio over bluetooth: i) I am using alsa-driver-0.9.6, snd-bluez-sco-2003-09-15 drivers. ii) For alsa driver and library I patched alsa-driver-0.9.6-bluezsco.patch,alsa-lib-0.9.6-bluezsco.patch respectively. iii) I am using bluetooth mono headset and on the linux PC I use a standard USB bluetooth dongle. iv) I have installed on a linux PC the alsa's snd-bluez-sco driver and its dependencies. I am getting the following results: [root@localhost BT-Test]# hciconfig hci0 up [root@localhost BT-Test]# hciconfig hci0 voice 0x0040 [root@localhost BT-Test]# hciconfig -a hci0: Type: USB BD Address: 01:5A:4B:20:07:DB ACL MTU: 192:8 SCO MTU: 64:8 UP RUNNING PSCAN ISCAN RX bytes:10132 acl:198 sco:0 events:421 errors:0 TX bytes:5332 acl:192 sco:0 commands:142 errors:0 Features: 0xff 0xff 0x0f 0x00 0x00 0x00 0x00 0x00 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: RSWITCH HOLD SNIFF PARK Link mode: SLAVE ACCEPT Name: 'BlueZ (0)' Class: 0x3e0100 Service Classes: Networking, Rendering, Capturing Device Class: Computer, Uncategorized HCI Ver: 1.1 (0x1) HCI Rev: 0x110 LMP Ver: 1.1 (0x1) LMP Subver: 0x110 Manufacturer: Cambridge Silicon Radio (10) [root@localhost BT-Test]# hcitool scan Scanning ...
