Hello all. Does anyone know how to get bluetooth working on CentOS 5? I can't pair any device. Things work perfectly on CentOS 4. Here is what happens: root at miho ~]# /etc/rc.d/init.d/bluetooth start Starting Bluetooth services: [ OK ] [root at miho ~]# hcitool scan Scanning ... 00:12:EE:XX:XX:XX K750i [root at miho ~]# hcitool cc 00:12:EE:XX:XX:XX [root at miho ~]# hcitool auth 00:12:EE:XX:XX:XX HCI authentication request failed: Input/output error I got no PIN requester on either phone and PC. On the same time on another console I have: [root at miho ~]# hcidump HCI sniffer - Bluetooth packet analyzer ver 1.32 device: hci0 snap_len: 1028 filter: 0xffffffff (scan) < HCI Command: Inquiry (0x01|0x0001) plen 5 > HCI Event: Command Status (0x0f) plen 4 > HCI Event: Inquiry Result with RSSI (0x22) plen 15 > HCI Event: Inquiry Result with RSSI (0x22) plen 15 > HCI Event: Inquiry Result with RSSI (0x22) plen 15 > HCI Event: Inquiry Result with RSSI (0x22) plen 15 > HCI Event: Inquiry Result with RSSI (0x22) plen 15 > HCI Event: Inquiry Result with RSSI (0x22) plen 15 > HCI Event: Inquiry Result with RSSI (0x22) plen 15 > HCI Event: Inquiry Result with RSSI (0x22) plen 15 > HCI Event: Inquiry Result with RSSI (0x22) plen 15 > HCI Event: Inquiry Result with RSSI (0x22) plen 15 > HCI Event: Inquiry Result with RSSI (0x22) plen 15 > HCI Event: Inquiry Result with RSSI (0x22) plen 15 > HCI Event: Inquiry Complete (0x01) plen 1 (connect) < HCI Command: Create Connection (0x01|0x0005) plen 13 > HCI Event: Command Status (0x0f) plen 4 > HCI Event: Connect Complete (0x03) plen 11 < HCI Command: Read Remote Supported Features (0x01|0x001b) plen 2 > HCI Event: Command Status (0x0f) plen 4 < HCI Command: Write Link Policy Settings (0x02|0x000d) plen 4 > HCI Event: Read Remote Supported Features (0x0b) plen 11 > HCI Event: Command Complete (0x0e) plen 6 < HCI Command: Remote Name Request (0x01|0x0019) plen 10 > HCI Event: Command Status (0x0f) plen 4 > HCI Event: Max Slots Change (0x1b) plen 3 > HCI Event: Remote Name Req Complete (0x07) plen 255 (auth) < HCI Command: Authentication Requested (0x01|0x0011) plen 2 > HCI Event: Link Key Request (0x17) plen 6 > HCI Event: Command Status (0x0f) plen 4 < HCI Command: Link Key Request Negative Reply (0x01|0x000c) plen 6 > HCI Event: Command Complete (0x0e) plen 10 > HCI Event: PIN Code Request (0x16) plen 6 < HCI Command: PIN Code Request Negative Reply (0x01|0x000e) plen 6 > HCI Event: Auth Complete (0x06) plen 3 > HCI Event: Command Complete (0x0e) plen 10 On CentOS 4 things work perfectly: [root at miho ~]# hcidump HCIDump - HCI packet analyzer ver 1.11 device: hci0 snap_len: 1028 filter: 0xffffffff (scan) < HCI Command: Inquiry (0x01|0x0001) plen 5 > HCI Event: Command Status (0x0f) plen 4 > HCI Event: Inquiry Result (0x02) plen 15 > HCI Event: Inquiry Result (0x02) plen 15 > HCI Event: Inquiry Result (0x02) plen 15 > HCI Event: Inquiry Result (0x02) plen 15 > HCI Event: Inquiry Result (0x02) plen 15 > HCI Event: Inquiry Result (0x02) plen 15 > HCI Event: Inquiry Result (0x02) plen 15 > HCI Event: Inquiry Result (0x02) plen 15 > HCI Event: Inquiry Result (0x02) plen 15 > HCI Event: Inquiry Result (0x02) plen 15 > HCI Event: Inquiry Result (0x02) plen 15 > HCI Event: Inquiry Result (0x02) plen 15 > HCI Event: Inquiry Result (0x02) plen 15 > HCI Event: Inquiry Result (0x02) plen 15 > HCI Event: Inquiry Result (0x02) plen 15 > HCI Event: Inquiry Result (0x02) plen 15 > HCI Event: Inquiry Result (0x02) plen 15 > HCI Event: Inquiry Result (0x02) plen 15 > HCI Event: Inquiry Result (0x02) plen 15 > HCI Event: Inquiry Complete (0x01) plen 1 < HCI Command: Remote Name Request (0x01|0x0019) plen 10 > HCI Event: Command Status (0x0f) plen 4 > HCI Event: Remote Name Req Complete (0x07) plen 255 (connect) < HCI Command: Create Connection (0x01|0x0005) plen 13 > HCI Event: Command Status (0x0f) plen 4 > HCI Event: Connect Complete (0x03) plen 11 < HCI Command: Write Link Policy Settings (0x02|0x000d) plen 4 > HCI Event: Command Complete (0x0e) plen 6 > HCI Event: Max Slots Change (0x1b) plen 3 (auth) < HCI Command: Authentication Requested (0x01|0x0011) plen 2 > HCI Event: Link Key Request (0x17) plen 6 > HCI Event: Command Status (0x0f) plen 4 < HCI Command: Link Key Request Reply (0x01|0x000b) plen 22 > HCI Event: Command Complete (0x0e) plen 10 > HCI Event: PIN Code Request (0x16) plen 6 < HCI Command: PIN Code Request Reply (0x01|0x000d) plen 23 > HCI Event: Command Complete (0x0e) plen 10 > HCI Event: Link Key Notification (0x18) plen 23 > HCI Event: Auth Complete (0x06) plen 3 Does anyone have any idea!?
