Bluetooth Help Needed!!!!!!

Hello

I can't seem to get my bluetooth USB Dongle working. I'd like to be able to send & receive files from my mobile fone.

When trying to connect it I get the following error messages:

' Failed to connect to the SDP server.

Please make sure that sdpd is running;
without it, other devices will not be able to find out
which services your computer offers. '

Can someone please help?

I need to know how to connect to this ' SDP server ' so my bluetooth device is recognized.

I'm running Mepis 6.0 on x86 AMD Athlon machine with 486mb Ram.

Thanks

In order to use bluetooth you need to be running a SDP server. This is included in kernel 2.4 and later and should therefore be in Mepis 6.0

You can download the latest versions of bluez-sdp server at http://www.bluez.org/ but this shouldn't be necessary.

Have you installed Mepis or are you running it from a live CD?

I don't know whether Mepis loads the required modules when used live. Anybody know?

I've installed mepis. But keep getting that same error message which is very frustrating because i have to keep going into windows xp to use my bluetooth dongle, which doesn't make me very happy!!

Try this link. It seems pretty easy to follow. Good directions.

http://www.bluetooth.com/Bluetooth/C...structions.htm

Also open kmenu/help and type bluetooth in the search. Good stuff right inside MEPIS

The program multisync sounds pretty good too. In synaptic. :)

I am Unable to configure my Bluetooth dongle because error messages are appearing that I've already described at the beginning of this thread

I need to know How to get a simple Bluetooth dongle recognized by Mepis.

What is an SDP Error? Why doesn't Mepis recognize my Bluetooth Dongle when plugged into USB Port?

I have already thought about installing kubuntu 6.10 if I can't receive help with this issue.

Although installing another operating system is not what i really want.

So if someone can help a Mepis Linux Noob & explain very simply in non-techy/geeky language The most simplest of questions...

How do I get my BLuetooth Dongle Recognized in Mepis 6.0?

Hope someone can help soon

You could try and re-install hwinfo using synaptic package manager. Hwinfo is what detects your gear. Also you may get an answer posting at the forum at mepis.org or at mepislovers.org . Sorry I couldn't have been more help. :scratch:

I've tried reinstalling Hwinfo and the kbluetooth & various other bluetooth related stuff but still no luck.

As per my earlier post your bluetooth device will only work if you have the SDP server module running.

Have you checked to see if sdpd is running? Open up a shell, change user to root and use lsmod to identify your loaded modules.

I'm in the dark here as I don't know if Mepis installs and/or enables this module in a 'standard' install. I would be surprised if they left it out given that bluetooth is so pervasive but I'm afraid I can't confirm it.

So, step one is to check that the module is loaded. If it isn't add it using whatever client Mepis uses to add/remove software.

(Any Mepis experts out there? This isn't a distro I know!)

I've also tried searching for it in Mepis package management tool called Synaptic Package Manager, but again can't see it anywhere.

I'm really at a loss here. All I have is you guys to help me, as i'm no linux expert.

But Always appreciate the help.. Any other suggestions?

It would appear that you don't have the required modules loaded.

If Mepis has the required files on its installation disk then use the package manager to search for and install the required files. That is the easiest way.

If you can't find them download bluez-libs-3.9.tar.gz and bluez-utils-3.9.tar.gz from http://www.bluez.org/download.html and install them.

I'm not sure if you are that familiar with installing on Linux so;

Download the files.
Extract them to a location such as your home folder. (eg put one in /home/bluez-libs-3.9 and the other in /home/bluez-utils-3.9)
open a shell such as Bash.
Change directory (cd /home/bluez-libs-3.9) to each of the folders in turn and install them by typing;

./configure
make
make install

You may hit upon (in my humble opinion) one of Linux's greatest weaknesses, that the files you are trying to install require others to be present, known as dependencies. You will then need to find and install the required files before you can finally install the one you want. This can be tedious and time consuming, hopefully it won't be an issue for you.

Don't give up! You will look back with fondness at all this effort and will be the forum bluetooth expert soon!

1. downloaded the files.
2. extracted to home directory using the commands you described above.
3. when i try cd /home/bluez-libs-3.9 it says no such file or directory, but they're definately in there.

any more suggestions appreciated.

many thanks

Try the hciconfig command in a konsole.
Hciconfig is used to configure bluetooth devices. This info and a lot more is gotten from MEPIS help found at kmenu, help. Type bluetooth into the help searchbar. There are lots of commands that you can use. The guide and more is in MEPIS help.
MEPIS help is the red and white life preserver. I know that you know. I just said that for newer users to see.

Finding Bluetooth in MEPIS 6.0 & 3.3.2

That didn't work for me.

I have 2 SimplyMEPIS installations running:

an old, heavily customized, "it needs to have been replaced yesterday, but I'm not quite ready to do that" 3.3.2
a brand new 6.0.

Neither shows "sdp[d]" in the output of

Code:

lsmod | less -N

They do show

Code:

## 3.3.2

67 bluetooth              41988  7 rfcomm,l2cap,hci_usb



## 6.0

10 bluetooth              43793  5 rfcomm,l2cap,hci_usb

OTOH,

Code:

ps -aux | less -SN

shows /usr/sbin/sdpd on lines 10 & 40 respectively. Obviously, YMMV on the actual line #'s.

hciconfig shows

Code:

# hciconfig

hci0:  Type: USB

        BD Address: 00:10:60:D1:40:FA ACL MTU: 384:8 SCO MTU: 64:8

        UP RUNNING PSCAN ISCAN

        RX bytes:111 acl:0 sco:0 events:14 errors:0

        TX bytes:310 acl:0 sco:0 commands:14 errors:0

in 3.3.2, but blank in 6.0. That makes sense -- I haven't tried to get it to work in 6.0.

Using APT tools:

Code:

## 3.3.2

# dpkg -l | head -5;  dpkg -l | grep blue

Desired=Unknown/Install/Remove/Purge/Hold

| Status=Not/Installed/Config-files/Unpacked/Failed-config/Half-installed

Slight differences, interesting. More interesting: the "rc ... " line in 3.3.2 -- that may be why I haven't been able to get my Sony Ericsson W600i to connect.

Hope the commands help you figure out what's going on. I think you have all or most of what you need installed by default & that your problem lies somewhere else.
