Introduction

For general infomration see: http://en.wikipedia.org/wiki/Bluetooth.

The following guidance might be useful in helping to configure Bluetooth on an Linux server.

My Bluetooth Configuration

The Bluetooth packages currently installed are:

[root@99dpr-004 ~]# yum list all | grep blue
bluez-bluefw.i386                        1.0-6                  installed

A nu ber of tools are available to query the status of applications and devices. For example:

Scan for devices:

[root@99dpr-004 etc]# hcitool scan

        00:01:E3:22:64:3F       MyS55

Query local devices:

[root@99dpr-004 etc]# hcitool dev

Query remote devices:

[root@99dpr-004 etc]#

Query specific devices for details:

[root@99dpr-004 etc]# hcitool info 00:01:E3:22:64:3F
Requesting information ...
        BD Address:  00:01:E3:22:64:3F

[root@99dpr-004 etc]#

The following commands can be used to display relevant details. For example, check the system configuration, USB:

[root@99dpr-004 objects]# lsusb
Bus 002 Device 026: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle
(HCI mode)
Bus 002 Device 021: ID 0ac8:301b Z-Star Microelectronics Corp. ZC0301 WebCam
Bus 002 Device 013: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 003: ID 046d:08a2 Logitech, Inc. Labtec WebCam Pro
Bus 001 Device 002: ID 152d:2329 JMicron Technology Corp. / JMicron USA Technology Corp.
Bus 001 Device 001: ID 0000:0000
[root@99dpr-004 objects]#

Expansion on this provides full details for the specific Bluetooth Dongle device as shown

[root@99dpr-004 objects]# lsusb  -s 002:026 -v
...
[root@99dpr-004 objects]#

Check the system configuration, loaded modules:

[root@99dpr-004 objects]# lsmod
Module                  Size  Used by
cdc_acm                14433  0

crc_ccitt               2241  1 irda
hci_usb                14657  2
rfcomm                 37213  0
l2cap                  25285  5 rfcomm
bluetooth              48069  7 hci_usb,rfcomm,l2cap

usbserial              26409  1 pl2303
...

Finally configure the system to automatically start bluetooth when the system is re-booted:

[root@99dpr-004 ~]# man chkconfig
[root@99dpr-004 ~]# chkconfig --add bluetooth
[root@99dpr-004 ~]# chkconfig --level 345 bluetooth on
[root@99dpr-004 ~]# chkconfig --list | grep bluetooth
bluetooth       0:off   1:off   2:off   3:on    4:on    5:on    6:off
[root@99dpr-004 ~]#

Conclusion

The bluetooth connection was successfully established.
