bluetooth: sdpd not working


I have RedHat 9 installed (kernel 2.4.20-8). I have installed Bluez packages. But, sdpd is not coming up. I am able to see device details using hciconfig -a. But when I try to run sdpd, it does not run. I checked ps -A | grep sdp, no process is listed. I am not getting any error also, so I am unable to understand why it is not running. I tried running hcitool scan, it does not list devices in vicinity. I tried capturing hcidump while running hcitool, It starts enquiry, gets one device in vicinity then there are no messages.

Can somebody help me on this?

Thanks in advance.

Update your kernel if at all possible. Bluetooth support is considerably better in the 2.6 series, so much so that I'd suggest if you updated these problems would resolve themselves.

Thanks for your response.

The problem is solved. We have to execute following command before running sdpd:
insmod l2cap

Thanks and regards,

i am facing a similar problem.i'm running on fedora core 4.when we run hciconfig hci0,it gives me a bd address but it doesn't give me the bdaddress of my bluetooth phone. On running hcitool scan, it isn't able to find anyb device. on running Bluetooth Device Manager, it locates my phone. but i can't do any file transfer.

Please advice.

May be you can look for following things:

Run 'lsmod' command and check if it lists following:
l2cap, rfcomm, bluez (or bluetooth), hciusb

probably l2cap and rfcomm will be missing.
Run following:
insmod l2cap
insmod rfcomm
insmod bluez
insmod hciusb

check if following processes are running:
hcid and sdpd

Use following command for that:
ps -A | grep hcid
ps -A | grep sdpd

when you run hciconfig check if iscan and pscan are listed.

I can tell only this much at the moment.
