Using USB bluetooth with slackware 12.0

vitalstrike82 · 06-14-2009, 09:27 AM

Greetings,

i'm trying to use bluetooth on slackware 12.0. I manage to do some search on google and find the steps to activate the blue tooth by setting the /etc/rc.d/rc.bluetooth

Code:

chmod o+x /etc/rc.d/rc.bluetooth

When i execute the file, my bluetooth usb manage to light up.

Code:

 hciconfig -a

produce these results:

Code:

hci0:   Type: USB

My questions are:
1) how to i scan for other blue tooth network around my area?
2) If i manage to find other blue tooth network, how do i connect to them?
3) If i want to stop using the bluetooth, how do i safely remove it or i can just pull out the bluetooth usb without any adverse effects?

Thanks

You would scan for other discoverable Bluetooth devices with the command:

Code:

hcitool scan

Actually connecting to something is slightly more complicated, and the method depends on what exactly you are trying to connect to and do. If you are trying to do file transfers with a phone for instance, as soon as you try the first transfer the phone will prompt you for the Slackware machine's PIN (default is 1234, this can be changed in /etc/bluetooth/hci.conf), at which point the devices will pair. But if you were trying to hook up to a headset, or use RFCOMM, the method would be slightly different.

As for removing the adapter, you can pull it out at any time. It isn't like a flash drive with a mounted filesystem, when you pull the adapter BlueZ will simply shut down that interface and wait for a new adapter to be connected. Although, obviously, you should wait for any file transfer or similar operation to complete before pulling it out...

Hi,
thanks.

Currently i'm trying to connect to my handphone.

Using hcitool scan enables me to search for my handphone bluetooth.
00:1E:E2:05:9F:C9 is the address of my handphone.

I try using:

Code:

hidd --connect 00:1E:E2:05:9F:C9

Code:

passkey-agent 0000 00:1E:E2:05:9F:C9

Code:

hcitool cc --role=m 00:1E:E2:05:9F:C9

All cannot connect to my blue tooth in my handphone. How am i able to connect?

Thanks for the advice..

None of those would connect to the phone, you would pair by attempting to use a service on the phone.

As I said before, if you wanted to transfer files, you would run a command like:

Code:

 obexftp -b 00:1E:E2:05:9F:C9 -l

Which would prompt your phone for the Slackware machine's PIN. It would then allow you to view the files on the phone from the computer.

Hi,

Thanks for the advise. I manage to connect to my handphone. However my handphone request for the passkey and when i enter, the connection failed which i think its due to that i'm not able to enter the passkey on my laptop.

From my understanding, the passkey input has to been input with matching passkey in my laptop and handphone.

However my handphone requests for the passkey, but i cannot input the passkey in my laptop, therefore i'm not able to connect.

I try to google online(the site address is display below) on how to use obexftp to connect to the handset with a passkey, but it seems that obexftp does not have the command to input the passkey.

http://www.irongeek.com/i.php?page=b...-3-man/obexftp

I have try to look at the man obexftp to see if i can enter a passkey while connecting to the bluetooth device but no info of how to enter the passkey on my laptop

How do i connect to my device?

thanks

You can change the PIN code in /etc/bluetooth/hcid.conf, then restart BlueZ. When prompted on the phone, enter in the new PIN code. You don't need to interactively enter it on the laptop.

Hi i have edit the file as you have suggest. This is the section i edit. I set the passkey to '1111'

Code:

# Default PIN code for incoming connections
	passkey "1111";

Then i restart it:

Code:

/etc/rc.d/rc.bluetooth restart

WHen i connect to my phone, i type 1111 on my phone but still cannot connect.

Am i on the right track?

thanks

vitalstrike82 · 06-18-2009, 11:23 AM

Oh i know why i cannot connect.

I need to set the passkey in /etc/bluetooth/passkeys/default

Thanks for the advice for the previous post. Without it, i not able to get this far

Hi, i got another problem again.

I manage to connect, but it list the folder in my phone and then disconnects instantly.

How do i choose a folder in my phone and send it to my pc? This is the output when i connect successfully, but it disconnects after listing the folders.

Code:

Connecting...done
Receiving "(null)"... <?xml version="1.0"?>
<!DOCTYPE folder-listing SYSTEM "obex-folder-listing.dtd">
<folder-listing version="1.0">
 <folder name="Images"/>
 <folder name="Other files"/>
 <folder name="Sounds"/>
 <folder name="Videos"/>
</folder-listing>done
Disconnecting...done
