So I plugged in the stick and typed in "lsusb" on the console to see what kind of chipset it had. On the console it said:
ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
turns out this chipset is well supported on Linux, immediately a red light in the stick started to blink.
How it works now:
The first thing I tried was sending a file with my phone, it found my computer as "zaphod-0", I didn't have to do anything for this, it just was there.
When I wanted to send the file it failed however.
On the blog of Pascal de Bruijn I read about his experience with Bluetooth and also read he installed the "gnome-bluetooth" package. I followed his example and a new application called "Bluetooth File Sharing" appeared in my "Applications -> Accessories" menu.
By starting this application a nice little icon appears in the notification area (system tray). So again I tried to send a picture from my mobile phone, and all of a sudden this dialog popped up:
Since "Arthur Dent" is the bluetooth identification of my phone, I knew it worked, so I pressed the "OK" button and waited. Now the progressbar on my phone started to work and also the icon in the notification area starts an animation, and after a while this dialog appeared:
Then I knew the file was transferred, and there it was on my desktop. Worked like a charm. Well actually there were some humps and bumps, but once I fixed those it works exactly like I told above.
What really happened:
At first when I started the "Bluetooth File Sharing" application and wanted to send a file from my phone it failed. So I grabbed my sister's phone an LG KG800 and from there I tried to send a picture, and immediately it worked.
If you experience problems with this file sharing you can start the "Bluetooth File Sharing" application from the console by using the following command:
whenever something happens on the bluetooth connection debug messages are printed to the console, a succesfull transfer should look like this:
conn_request: bdaddr 00:17:4B:1D:0B:E9
conn_complete: status 0x00
** Message: Incoming connection from 00:17:4B:1D:0B:E9
** Message: Device 00:17:4B:1D:0B:E9 is about to send an object.
** Message: File arrived from 00:17:4B:1D:0B:E9
** Message: Filename '200702171898.jpg' Length 308934
** Message: Saving to '/home/lgespee/Desktop/200702171898.jpg'
Between the "** Message: Device ..." and "** Message: File arrived ..." the file is actually being transferred, so it can take a while for the lather to show up.
When I tried to send from my phone I only got to "** Message: Device ..." and then my phone told me the transfer failed. Since I am used to problems with my phone I gave it a good old reboot, and that did the trick, now it works like it should.
Tip of the day: Never ever buy a Nokia N70, cause it sucks in everything, bigtime, thanks Nokia.
