Controlling Bluetooth DUN with Upstart
 

Hi all,

I spent some time today writing a suitable upstart script to control bluetooth DUN. This will let it start automatically and generally act seamlessly.

You can read the details and get the script from my blog post

Thank you for sharing!
I was searching for somethinig like this since long time!
I'll try it in the next week and will post the results. :)

Re: Controlling Bluetooth DUN with Upstart
 

Is there a way to package this into a .deb and push it into extras or otherwise make it simple for users to do? I'd hate that a cool thing like this that could benefit a lot of people and demonstrate the benefits of an open source platform ends up being exclusive to users who actually know what bluetooth DUN, upstart etc. are.

Re: Controlling Bluetooth DUN with Upstart
 

Great! I don't have the device yet but your script is going to be one of the first things I'll install. So, thanks :)

One thing I'd like to know - if there are any symbian experts around - is *if* and *how* a symbian phone can connect to the internet by tethering to another phone through bluetooth dun. This is because I am going to have my voice sim in a symbian phone and my data sim into the N900. Occasionally I'd like to use some symbian apps that go online, and the simplest way could be to tether. Any hint?

Re: Controlling Bluetooth DUN with Upstart
 

What happens if Bluetooth is disabled at startup and is enabled manually after that? I only want to enable Bluetooth when I need it and then it should be already possible to connect my notebook to the N900 and use the 3G connection from the N900.

Re: Controlling Bluetooth DUN with Upstart
 

So, when you disable bluetooth in the UI, the hardware is turned off but all the software keeps running, so that doesn't cause any issues.

Re: Controlling Bluetooth DUN with Upstart
 

Hi ... I tried to setup the upstart script as per your suggestion:
However the job doesn't seem to automatically start after rebooting the N900:
I need to start it manually via:
Do you have any idea?

Re: Controlling Bluetooth DUN with Upstart
 

Looks like I underspecified the starting constraints. It probably needs something that could start after bluetoothd. I'll have to investigate and find out what it is.

Has anybody got DUN connection working with Windows Vista?

Re: Controlling Bluetooth DUN with Upstart
 

I too had a problem with bluetooth-dun not starting after a clean boot.

I'm also going to document, for posterity, the steps I had to go through to get DUN running between a Gentoo Linux laptop and T-Mobile, using the N900 as the relay.

The N900 setup was more or less what you specified (specifically putting http://intr.overt.org/misc/bluetooth-dun into /etc/event.d and running `start bluetooth-dun`) except that I kept getting "spawning too fast" messages when testing.

For my laptop, I first had problems pairing--I'm sure this is some bug with the bluez version I was using, but I eventually gave up and put the line "34:7E:39:24:88:FC 9339" in /var/lib/bluetooth/*/pincodes where the "34:..." is the bluetooth address (from `hciconfig -a` on n900) and 9339 is the pin I wanted. A `rfcomm connect 0 34:7E:39:24:88:FC` then forced a pairing attempt and I was able to enter the pin 9339 on the n900. Also, the n900 was unable to see the laptop during discovery until I ran `hciconfig hci0 piscan` I don't think this was important to my efforts because the rfcomm explictly requested the pairing.

I have, more or less, the following contents of my /etc/bluetooth/hcid.conf:
------------------------------------
options {
autoinit yes;
security user;
pairing multi;
}
device {
name "BlueZ@%h (%d)";

}

------------------------------------

Note my use of internet2.voicestream.com and the username/password of guest/guest. One of those two changes (from internet3.voicestream.com and no username/password) was what I had to do to get DUN working over and above what has been documented here to date.

Re: Controlling Bluetooth DUN with Upstart
 

I've got a fix for the failure to start automatically and updated the script. Details on my blog.

Re: Controlling Bluetooth DUN with Upstart
 

Great. Do you know how to connect the N900 with Windows 7 and use the 3G internet connection from the phone? Do I need any specific drivers or programs? With my Nokia 5800 and Windows 7 it was very easy. Just connect the phone via Bluetooth, go to the device control panel and click on "Connect". No program or additional driver was needed. Is it the same for the N900 with this script?

Re: Controlling Bluetooth DUN with Upstart
 

Now it starts correctly but i still have issues in connecting.
In windows7 i get error 734, PPP connection terminated.
I'm using the same dial-up connection i use with n900 & usb cable.
Any idea?

DaSilva: once the script is running and device is pared, right click on n900 in bluetoooth devices, you will find dial-up or remote connection in contextual menu.
I'm unsure how to set the dialup as it is not working for me...

Re: Controlling Bluetooth DUN with Upstart
 

You are the Man!!!
It is starting/working like charm for me too.(WinXP+PC Suite Drivers)

(OT: I still have some issues with other tools - proftpd ftp server - trying to automatically start them on boot and maybe same cause applies there)

Could you please suggest the best way to troubleshoot/monitor upstart execution?

Re: Controlling Bluetooth DUN with Upstart
 

This is sort of going in the reverse direction.
Does anyone have any experience tips on Bluetooth PAN between N900 and Windows 7?

The 3G reception in the Office is rubbish and we don't have wireless, so I'm thinking that connecting to my office PC via bluetooth and then using its Internet connection might be the best thing.

Re: Controlling Bluetooth DUN with Upstart
 

It started working for me too with Windows Vista after installing PC Suite, couldn't get it working before that. Works with Ubuntu&blueman without any tricks.

I'll say it's ready for packaging as 'Bluetooth DUN support'

Re: Controlling Bluetooth DUN with Upstart
 

Thank you, Philipl.

As another poster mentioned, what are the chances of packaging it for us code idiots?

Re: Controlling Bluetooth DUN with Upstart
 

I expect to have time to put a package together this weekend.

I'm glad people are finding it useful!

Re: Controlling Bluetooth DUN with Upstart
 

Packaging was easier than expected. It's now available from the extras-devel repository. I will be beginning the promotion process but for the impatient, you can turn on extras-devel to access it. Please take the warnings about this repository seriously and exercise caution over any packages you do install, including mine!

Re: Controlling Bluetooth DUN with Upstart
 

quick comments:

use XB-Maemo-Display-Name field
use XB-Maemo-Icon-26 filed (48x48 icon)
Use more user oriented description. Do not mention upstart script in description. It is Bluetooth DUN support, that people might even understand.

Re: Controlling Bluetooth DUN with Upstart
 

Thank you very many, although just after I got this working I remembered Joikuspot :)

Re: Controlling Bluetooth DUN with Upstart
 

Quoting myself as this is still not working in windows 7 nor win xp. :(

Re: Controlling Bluetooth DUN with Upstart
 

The bluetooth-dun package is now in the main extras repository
