Enmeshed in a "blue network&quot

The subject of this research - opportunities for the organization of personal wireless Bluetooth-based network computer with an adapter Bluetooth USB - Billionton USBBTC1A. In this article we will test the connection to a PC with mobile phones and handheld computers using a wireless connection. Of course, all mobile devices that participate in the experience, support Bluetooth. To get started all a bit will tell you about the virtues of personal Bluetooth-networks in relation to our little experiment in which, again, involved a desktop computer, mobile phone and Pocket PC, networked with "golubozubogo" USB adapter. So, combining the desktop to the cellular handset wirelessly, you can afford a lot - to throw the contacts stored in the mobile phone on the big PC or even, for example, popolzovavshis "ICQ" to work where you are in addition connected to the LAN desktop, there is a stern administrator , the ban on all kinds of internet pagers. In the latter case will the following scheme. Authorized service continues to use over a network connection, and configure ICQ to work through their cell phones. In addition, the use of Bluetooth-bundles "PC + mobile phone" is obvious if we do not have my phone jack and modem. As for the unification of Bluetooth-channel handheld computer and its desktop counterpart, here again the mass of applications - from wireless synchronization of data stored on PDAs to surf the Internet or LAN through a big computer. However, in the latter case, you are somewhat limited area of ​​Bluetooth - the order of 10 meters, but still nice. Now, Own, about the main thing being tested - USB adapter for a large computer.

Here are its features:
• Class 1 - the radius of 100 m (applies to that radius only if the reply device supports such a distance). Class 2 - 10 m

Specifications:
• Bluetooth v1.1
• USB 1.1 port
• Compatibility - Windows 98/2000/ME/XP.

Detailed list of parameters Bluetooth USB adapter, you'll find in this plate. Included with this device comes with software CD, installation guide, extension at 50 cm USB / USB. Begin, as well as advising management, with the installation of the software (driver and application software) from the disk. Prior to the installation software did not connect the adapter is better, though do not worry if it is connected in advance, will not happen. The system itself will search the USB drivers, and only need to abandon its proposal. So, install software. There are no deviations from the standard process. After the download is complete on the computer, the following changes. At the bottom of the toolbar icon appears in Bluetooth. This icon will be red until the adapter is connected and becomes green when we finally connected to the USB port. On the desktop, as well as in the "My Computer" icon appears My Bluetooth Places, which should push to open the main setup menu. We begin to configure the device by clicking the icon Bluetooth Setup Wizard. The main thing - to choose and configure the options that we need in the future. On the order of each of them: - PIM Item Transfer / PIM Synchronization Responsible for file transfer and synchronization of personal database (for example, Microsoft Outlook) c of such a base and a business card and other devices. It is not clear yet, it is useful to us or not, because when working with the Pocket PC for these purposes will be used by specialized application (ActiveSync for Pocket PC). However, in our experience will participate and a mobile phone, so put a check and set up to synchronize with Microsoft Outlook. - File Transfer Sharing files between devices. This option makes sense to connect and define the folder where you will be sharing files. - Network Access Access to the network will allow access to network resources of a computer (eg Internet access) to mobile devices via Bluetooth-connection. Since our big computer is connected to a network, you may be able to somehow use this resource. Pocemu assign configuration settings - Allow access to the internet through this computer ". - Dial-up Networking Ability to set a bunch of: a mobile device - "a big computer (via Bluetooth-connection) -> Internet (via a modem connected to a large computer). Since we do not have a modem, then test this original way, we will not.- Bluetooth Serial Port But this possibility, we need one. It is through this virtual port will be an interaction Pocket PC via ActiveSync c big computer. When configuring the system suggests us to use the port COM7 (on other machines can be offered to other ports depending on which of them are free). - Audio Gateway possibility of using Bluetooth-headphones. Headphones have not yet, but the plug and this feature - a sudden end of the study that will change for the better:) - Headset And this facility allows you to use a microphone and speaker of the computer instead of the relevant attributes of a mobile phone or any other device, which we try to connect. In other words, the computer becomes a big earphones. Connect and this chip. From the unencumbered leaves us with only the "Fax", which certainly will not activate. Now we are ready to open the Bluetooth-Ups between different devices.

Experience first, or the connection of a large computer with a mobile phone

We have a little outdated but reliable tube Ericsson T68. First of all, maximally briefly about how to enable Bluetooth in the mobile phone. In the "Connections" (Sonnect), in line Bluetooth, select the Operation Mode and translate mode to ON. Then on the desktop in a row Discoverable includes options to find a mobile phone. This mode runs for 3 minutes, so you immediately start the procedure by using the menu Find Bluetooth Devices. Our T68 remarkably quickly discovered a big brother, so that count - half the job done. Now it is necessary to conduct the process of "pairing" (pairing) devices, that is, give them the opportunity to get to know each other, share passwords. Dating procedure is performed only once, so that in future the device when trying to connect immediately "recognize" each other and start working together without formality. (Note: you can set up communication so that each time a connection between the devices will be prompted for a password). Right click on the icon in your phone and select Pair Device. The pairing process went. On the computer screen in the bottom menu appears Bluetooth PIN Code Required. Introduce an arbitrary number and a similar message is already on the small screen phone. Introduce the same number and familiarity completed. Phone icon on the top left there is a check mark, indicating that the pairing process was successful and can be ready for the next experiments. Go ahead. Click on the icon of the phone and go to the following menu: There is a set of icons, but we are interested only connection Dial-up Networking. Click on the Dial-up Networking: On your computer, there is a window "Connect to Bluetooth Connection». Here you need to type a user name and password, depending on whether, to what cell phone is connected to the operator. ... And now the connection is established. Here you need to make a brief remark. We assume that our phone is connected to the network GPRS. Information on how you can do it you will find on the sites or carriers to HPCru. In our case - in rows "User" and "Password" enter the mts, in the row "Type" - * 99 #. The latter depends on phone model - see the relevant information about your phone on the operator's website. The speed of connection in the GPRS may be different, in our case, it reached 115 Kbit / c, which is quite decent. As you can see, the icon has a green phone. This means a working connection. That's all for this step. You can now use cell phone as a modem and to check out the Internet. On the big computer in the Internet Explorer settings, select "Tools" -> "Internet Options" -> "Connect". Click on "The compound via Bluetooth". In the second test Let us install a Bluetooth connection between a large computer and handheld Pocket PC.

Experience of the second, or the connection of a large computer with a pocket

In general, everything as well as a mobile phone. First of all, activate a Bluetooth mode on Pocket PC. If you have a HP iPAQ, then all is simple. Turn radiorezhim, start the Bluetooth Manager and launch the "Search" (Search). Choose the device to synchronize and be sure to put a tick in the box ActiveSync Partner. And that's all. Cparivat device, of course, is not required. At this stop, we will leave until the iPAQ alone and look so simple it's all done on other devices. It turned out that when working with the Pocket PC without a built-in Bluetooth (where as radioadaptera uses CompactFlash card or SD), the situation is different. We experimented with promyshlennnym pickpocket Symbol PDT 8000 and card Anycom Bluetooth CompactFlash Card. So this bunch steadfastly resisted all attempts to establish a connection (by the way, in this case do not dispense with the procedure of pairing) and earned only after a few reboots of both machines. Below are screenshots mikrokommentariyami showing the sequence of connection in this case 1. Initiating a connection c screen PocketPC 2. Found a Symbol 8000 c Anycom Bluetooth. T68 handset is in the pocket. Pay no attention to nowhere invading notebook LAWGROUP (in our office do not exist, apparently the owner in an adjacent room). 3. The process of mating, the authorization is required. 4. Enter the password (and then the same on Pocket PC) 5. All right, the icon appeared checked, you can now connect. Now the iPAQ, Symbol, and are ready to further hostilities, which are the same for both devices. We continued to experiment with Symbol, so the icons on the following screenshots will simbolovskimi. So, what to do next? Next you need to prepare ActiveSync on both machines. Since our earlier work with Pocket PC AstiveSync through the physical port (serial or USB), but now we need to change the port because the Bluetooth connection uses in its work to a virtual port. How do you know what this port? Port we have automatically established at the very beginning of the article, when we installed the drivers for the adapter. Go to My Bluetooth Places -> My Device -> and see the following picture: Remember the port that corresponds to the line My Bluetooth Serial Port - we have it COM7 (not necessarily that you will have the same description of the potential problems of looking at the end of the article).On the desktop computer run ActiveSync -> File -> Connection Settings and select the port COM7 (he must be on the list of ports, but there may be exceptions, again - about this at the end of the article). If the iPAQ on this for almost everything, then Symbol still need to configure ActiveSync on the device itself. Why in the start menu, click ActiveSync, and select the appropriate port (in my case BTActiveSync (COM6), do not be alarmed that the port is different from the port on a desktop computer, it's as different machines). And now, after all the ordeals in the Start menu, click on the BT ActiveSync and install ActiveSync ... coedinenie! Now you can enjoy all the benefits provided by ActiveSync (email, other opportunities Outlook, transfer files, etc.) at a distance of 10-15 meters because of a computer. And now, as promised, a few words about the problems that, despite all the carefully and consistently carried out the procedure may still occur. Sometimes (and not so rare) that the compound, despite the fact that everything was done correctly, still does not want to install. Bluetooth developers in such cases has been criticized generally for Microsoft ActiveSync (quote: "it happens that ActiveSync for some unknown reasons, switched to a strange situation in which some unknown reason the connection is impossible"). Microsoft has a different point of view on these issues, because we all know that Bluetooth is yet still somewhat damp (more on this issue can be found at www.cewindows.net). But what if we do get into this situation?

The first tips are:
1. restart both computers. If not helped, then Look at the following paragraph.
2. reconfigure all the ports back in and carry out the procedure ActiveSync ordinary physical means. Then again to reconfigure the ports under the Bluetooth. And if it did not help, then www.cewindows.net described a problem that, who knows, may prevent you, too. About it - just below.

There are situations when your computer employs a large number of virtual ports for all different peripherals. So, when you install the drivers for the Bluetooth adapter, the program selects the first free port, and if you are busy all the ports to COM9, respec-tively it configures itself by COM10. No error messages or some program does not give warnings (yes, because any mistakes and was not). And the problem is that ActiveSync (in any case before version 3.5) does not support ports over COM9. In order for this fix, you must uninstall the program, kill all unnecessary ports and re-installlirovat software to produce the desired port. We hope that this little manual will serve as a model for organizing personal "golubozuboy" network. Good luck to you and comfortable existence within it of:) The authors, translation:
