Solved! : Trouble solving of Bluetooth Set up new device failed error. An error of Bluetooth device pairing of Ubuntu 10.04 Lucid Lynx

Personal File Sharing Preferences menu


Nokia 2330-c mounted as a removable media

Set up completed

The key is in "introducing" our cellphone first to the system

Previous days, I was very annoyed by an error (perhaps that was a bug) of Ubuntu 10.04 Lucid Lynx. The error was I couldn't make bluetooth pairing between my computer and my cellphone. I often use bluetooth connection to transfer any files, from and to computer-cellphone (photos, Java applications). In the previous versions of Ubuntu (9.04 and the below), I never get any trouble to make bluetooth pairing. But in Ubuntu Lucid, I got my pairing process failed in the 'Set up new device' step. For so many times I'd tried, but I always got an error. Again and again I tried to make pairing and always been failed. I didn't know where the mistake was, but when I followed the wizard, I always got the error. At last, I got myself desperate because of its error and for long time I gave up and had been lost my interest to find the solution.


But recently, in the rest time, I made an experiment and unintentionally, I got the trouble solving. The key is we don't have to follow the wizard which the first step is 'Set up new device', but we could “introduce” our cellphone first, by sending it a file from our computer, and then we could follow the wizard. This is surely works to me. I can successfully receive and send files from my computer. Also, I can successfully 'Browse the device' so I can see my cellphone being visible just look like a removable media.


These are the steps to make a bluetooth pairing between Ubuntu 10.04 and cellphone:

  1. Plug the bluetooth dongle in; Or in some laptops, switch the internal bluetooth on :)

  2. Switch our cellphone bluetooth on.

  3. At the bluetooth icon in the notification area in the upper panel, click and select 'Send files to device'.

  4. Select any file (the smallest in filesize is picture) and wait for a moment until our cellphone is detected. Then, when our cellphone is visible, select our cellphone and transfer process will be ran.

  5. Go to the bluetooth icon once more, and for now, select the choice 'Set up new device'.

  6. When our cellphone is visible, select it. Leave the system to make automatic PIN selection.

  7. An confirmation about pairing process will be shown at our cellphone. We will be asked about the PIN code. Enter the PIN code, and press OK.

  8. The process is finished, and we can now use the connection to transfer any files, or to make a dial-up Internet connection.


I was very satisfied by this trouble solving. And even, now I am really satisfied by the bluetooth features of Ubuntu 10.04. I can make my computer always be visible to other bluetooth devices. I can make my computer always be ready to receives any file from any devices, without making a pairing process first.


Notes:

To make our computer always be ready to receives any file from any devices, we have to manage it by accessing Bluetooth Preferences menu. Go to System>Preferences>Bluetooth, or click at Bluetooth icon in the notification area, and select 'Receives Files' button. And then, will be shown a dialog menu titled 'Personal File Sharing Preferences'. Check all of the selections.


For the technical comparison, these are the equipments that I've used:

  • Ubuntu 10.04 Lucid Lynx with original kernel

  • CPU Intel Pentium IV 2.4 GHz

  • 512 MB Memory

  • K-One Bluetooth USB Dongle

  • Nokia 2330-c

Ubuntu Kylin 19.04 Review : A Gorgeous Windows 10 Clone

It's been quite a while since the last post I wrote in this blog. My daily life prevents me to write another stuff about Linux Desktop, and now I'm curious to take a look to the Ubuntu Kylin 19.04. Ubuntu is always be my favorite distro. It supports huge number of hardwares, it has probably the largest Linux software repository. It is also --the most important thing-- very easy to install, even for beginners.  But for some couple of years, because of technical reason, I stopped to play around with the Ubuntu releases. I stood for KDE Neon and became my primary OS because of its simplicity and the look. Few days ago Ubuntu has released its newer version, Ubuntu 19.04 codenamed Disco Dingo. I'm yes impressed by the progress Ubuntu developer has made, especially the way they arrange the GNOME desktop to match the Ubuntu theme. But the most interesting flavor of this release is Ubuntu Kylin. It's an official Ubuntu flavor, designed for Chinese People with its own...

How To Speed Up Your KDE Plasma Desktop (KDE4)

KDE is one of the oldest desktop environment in Linux. While GNOME (the other desktop that as old as KDE) is trying to built its own style of user interface, KDE from the beginning seems to mimics the Microsoft Windows' "classic" user interface. Thus, KDE has its own user base, especially for them who still in love with the Windows' philosophy : a simple desktop, with a single taskbar in the bottom, and a start menu in the left. Personally, I love KDE. It's gorgeous and eyecandy. But sometimes, I feel KDE is little bit slow in my older hardwares. So, after some experiences, I've found some tweak how to make KDE Plasma Desktop Runs Faster . 1. Change The Compositing Engine  Go to System Settings>Desktop Effect>Advanced , and change the Compositing type from OpenGL 2.0 to XRender. 2. Remove All Bloatware Apps There are some uneeded apps installed in Kubuntu (my favorite KDE distro) and you could safely remove them. Here are my list : ...

Q4OS 4.6 "Gemini" Review: A Real Hidden Gem

Distro hopping is a fun adventure. It's a pure joy you can only find in GNU/Linux world. It's a nature you want to escape from what I call 'comfort ecosystem'. You need to play, trying something new even for a few little differences. For a long time I've been using Ubuntu family as my daily driver. The main reason is probably just same as any other Ubuntu user: it's reliable. You can't go wrong with Ubuntu. It works almost in any device, even for the newest one. It is the ultimate Linux distro you can rely on. However, sometimes, you will feel bored. The temptation to flirt with other new distro is unbearable. There are a lot of hot new Linux distros waiting to try.  A Real Hidden Gem I've known this distro for a quite long time. At first, it offered Trinity Desktop as the main desktop, which brings me the sweet memories about KDE3. It is simply fast, stable, almost without any issue, and it is based on Debian. I install it on my old machine and I love t...
