[Bluez-users] BlueZ, Linux and Windows

[-- Attachment #1.1: Type: text/plain, Size: 1689 bytes --]

Hello you all

I’m quite new at Linux and BlueZ, and I’m having lots of problems to get it
into work. I have a Linux PC (Fedora 4), a Windws XP PC, and a Ericsson T630
mobile phone.

I have also, a TDK Bluetooth USB adapter, and a conceptronic one, both found
in the BlueZ supported hardware.

 

Using the Fedora 4 PC, I have managed to discover the winPC and the mobile,
but when I try to connect to them an error is displayed (cannot attach
specified device). I also tried to pair the phone with the Linux PC, but an
error is displayed in the mobile. When I start the pairing from the Win PC,
the Linux one get’s blocked.

 

An application called “Bluetooth manager” seems also not to work. Nothing
happens when I try to use it…

 

I need some help, on basic issues. Perhaps some “blueZ for dummies” manual
;)

I hope somebody can help me.

 

Best regards and thanks in advance

As one source you could study the information provided by the following link 

http://www.holtmann.org/linux/bluetooth/

special remark: the phones expect normally a running service on the other side 
depending from which menu point in the phone you try to connect to the other 
side.

Hi Andreas

I have review all information in Bluez home page and the one provided by
you. Most of it is outdated... I haven't managed to get it into work. I
think I'm missing some basic step... Let me explain you what I have =
done...
- Install Fedora 4 (gnome-bluetooth, gnome-bluetooth-libs, =
bluez-hcidump,
bluez-pin, bluez-utils, bluez-libs included)
- hciconfig hci0 up
- hciconfig (shows the device up and running)
- hitool scan
- mknod /dev/rfcomm0 c 216 0
- sdptool browse <addr>
- modify /etc/Bluetooth/rfcomm.conf
	Rfcomm0 { 	bind yes;
			device <addr>;
			channel 1;
			comment "FC4-BT";
		  }
- Create file: /etc/bluetooth/mypin;
	#!bin /bash
	echo "PIN:1111"
- In /etc/Bluetooth/hcid.conf
	pin_helper /etc/Bluetooth/my-pin

- hcid -f /etc/Bluetooth/hcid.conf (to reload file)
- rfcomm connect /dev/rfcomm0 <addr> 1

At this point, my windows PC shows a message requesting the PIN, I type =
1111
but the FC4 box shows: "can't connect to RFCOMM message"

Thanks in advance for your help.

Regards

Hi Esther 

anyhow you should play a little bit with "hcidump -X" for for getting in touch 
with the bluetooth stack communication.

When you would like to connect to another device then you normally would like 
to use (connect to) a service (on that device). For reaching this try to read 
out the service database of the other device (e.g. sdptool search ...). with 
this information you could select the service you would like to connect (on the 
other device). <= e.g. take the corresponding channel on the other device and 
connect to them.

Which address did you used? What is behind the channel 1? Did you checked the 
sdp database on the other device??
Does your hcidump trace shows a successful PIN delivering to the BT-chip (on 
the linux pc)?


When you try to connect your phone (e.g. in the context of sending vcards)to a 
clean bluetooth linux-pc then this will fail beause of missing "active" sdp-
records (eg. OPUSH, HF) with the specific channel number Y, a listening rfcommX 
socket on channel Y and some kind of server functionality (which takes the 
vcard) which will be called from rfcommX.  


Regards Andreas
