[Bluez-devel] Service registering but not visible

[Bluez-devel] Service registering but not visible

[-- Attachment #1: Type: text/plain, Size: 1447 bytes --]

Hi,

When i add a service using the command

root@darkstar:~# sdptool add --channel=13 OPUSH
OBEX Object Push service registered

And then using my Nokia 6600, search for available services no services are shown.

This is the setup i'm using

Linux distr: Slackware 9.0
Kernel: 2.4.22
Packages installed: 
bluez-libs-2.7-1.i386.rpm
bluez-sdp-1.5-1.i386.rpm
bluez-utils-2.7-1.i386.rpm

Am i missing something or doing something wrong?

Thanks

Dan






I start the daemons hcid and /usr/sbin/sdpd and can discover services on my nokia 6600 using
sdptool browse.

Using rococo's java api's i have created a server(linux) and a client(nokia 6600) but my nokia
 does not find the service i have registered via the server.

I have checked my code against other working java bt servers that register their services and everything is fine.

So then i used the command 

"sdptool add--channel =13 OPUSH" to add a service (presumably register as well) and this was successful.
"Service OPUSH added" was the message I think. But still I could not see this service through my phone.
(I am using benhui's BTBrowser that happily discovers bluetooth services when i'm using windows).

Do you have any idea what i might be missing or where i might be going wrong? I've spent so many hours trawling 
through the internet reading anything on bluetooth and can't see where i'm going wrong.

Thanks for your time

Dan

check with "sdptool browse local" if the service record is really
present.

Run "hcidump -x" as root to see for what services your phone is
searching and try to set the correct class of device bits.

I tried the commands you suggested with the following results:

The output from "sdptool browse local" seems to point to some kind of
configuration problem. Do i need to
register my local device address to the sdptool or the sdpd?

Thanks

Dan

Hi Daniel,

after that check what /proc/bluetooth/l2cap is saying.

That is the problem. Make sure that sdpd is really running.

This means "Connection refused - PSM not supported" and leads to me that
the sdpd is not running.

Hi Marcel,

It does look like there is something wrong with the sdpd daemon but it does
seem to be running and the sdptool can find services on my nokia 6600.

Below is the output from a "ps aux", a "sdptool search 0x1101" and a
"lsmod". I know there's a lot of info in the ps aux but i thought i'd
show it all to you in case there is something else you might be able to see

I hope this helps to decipher the problem.

Hi Daniel,

these are two different things.

You have two hcid running, which is never good. Make sure that only one
hcid and one sdp are running.

The sdptool don't need the sdpd to find the records on remote device. We
talk here about local SDP records.

> I hope this helps to decipher the problem.

No this was not helpful. Check /proc/bluetooth/l2cap and take a look at
the syslog for error messages from the sdpd. Do this more than once,
because I think there will be changes within the usage.

> Also, I'm not too sure what a PSM is - could you explain?

Maybe you read the Bluetooth specification or look it up in an Internet
search engine ;)

Regards

Marcel

Hi Marcel,

I've switched from Slackware to RedHat and everything is working fine now.
Sorry to have wasted your time and
thanks for your help.

Regards,

Dan
