Although the Bluetooth wireless networking protocol is not really designed to serve
as a full-fledged networking service, IOGEAR
has produced a set of modules that plug into USB ports on computers to
provide Bluetooth service for Windows and Macintosh computers. Bluetooth
services resemble some of the services you would get from a wireless network,
including file transfers. What is Bluetooth? I quote from IOGEAR’s
excellent treatise :
What is Bluetooth?
Bluetooth is a standard for a small, low-cost,
low-powered radio chip that can be used by computers, printers, mobile
phones, etc. A Bluetooth chip is designed to replace cables by taking the
information normally carried by the cable, and transmitting it at a special
frequency to a Bluetooth receiver chip, which will then give the information
received to the computer, phone, printer, etc.
Why Bluetooth
Cables have become the annoyance of many offices
and homes. Most of us have experienced the “joys” of trying to figure out
what cable goes where, and getting tangled up in the details. Bluetooth
essentially aims to fix this — Bluetooth is a cable-replacement technology.
No More Wires |
So what does Bluetooth connect to? Devices like printers, Bluetooth-equipped
cell phones (some of the fancier ones, perhaps those that have PDA features),
as well as other devices.
This kit consists of two small modules that plug into USB ports on two
computers, which can then be networked together within a limited range
(330 feet) and for a limited speed (Kbps). IOGEAR calls the network created
by these Bluetooth modules a PAN (Personal
Area Network).
If your computer doesn’t have room to plug in the modestly sized module,
IOGEAR thoughtfully provides an extension cord. The cords also let you
position the modules where they may be able to “see” other Bluetooth services
better.
I elected to install the PAN on two computers: my Dell Dimension 4100
Pentium III desktop machine and my Hewlett-Packard Pavilion ze-1000 series
notebook computer, both using Windows XP. The installation process appeared
easy: first you install the software from a distribution CD, and then you
plug in the device to a USB port and let plug-and-play set up the drivers.
That’s for a Windows computer; Macs will be different. So how did it go?
The Bluetooth software installed easily. A dialog box warned me that
Microsoft had not certified any Bluetooth drivers, so the drivers provided
would be unsigned. I told Windows XP to install the drivers anyhow. After
the software installation was finished, I restarted the computers and plugged
in the 2¾-inch long Bluetooth modules. The plug-and-play service
detected new hardware and installed the drivers. There were two new icons
on the computers: one labeled My Bluetooth Places and a tray icon labeled
Bluetooth Configuration. I clicked on the My Bluetooth Places icon and
told the software to “View devices in range.” That was supposed to detect
other Bluetooth equipped devices. The software could detect no other devices,
even though the Bluetooth modules were only 3 feet apart. I then opened
the Bluetooth Configuration window and discovered that one of the two Bluetooth
modules appeared to be not working. I swapped the two modules between the
two computers, and discovered that the module still didn’t work. In desperation,
since the deadline for this issue of the PC Alamode was fast approaching,
I downloaded and installed a newer driver for the hardware. The new driver
was able to recognize the errant module, but the two computers still couldn’t
find each other’s Bluetooth availability. I dashed an e-mail to IOGEAR
telling them of the problem and encouraging a fast replacement of the possibly
defective module.
A review of IOGEAR’s Web site turned up a tech support document citing
compatibility problems with some Dell computers. Apparently some Dells
don’t put out enough voltage through their USB ports to power the IOGEAR
Bluetooth adaptors. Dell recommends using an external powered hub to provide
additional power to the adaptor. But I had already done that, so that didn’t
solve the problem. The web site also mentions some failures of Windows
XP to detect the adaptors if they are the first USB devices plugged into
the computer. However, on both my computers, the Bluetooth modules were
not the first USB device plugged in, and both computers recognized the
fact that the Bluetooth adaptors were plugged in. Another tech support
note cautioned me to install all Windows XP updates from the Microsoft
Windows Update site. I had already done that. I concluded that one of the
modules was not quite right. Our indefatigable hardware and software acquisition
guru, Larry Grosskopf, went into action. He called the company and explained
our situation. They agreed that the problem sounded like a hardware failure,
and to make this review possible, shipped a replacement module via overnight
Fedex. What great support!
I eagerly plugged the new modules into the back of my notebook computer
and my powered USB hub. Both announced their arrival with a couple of beeps
through the computer speakers. Then came the moment of truth: I clicked
on the My Bluetooth Places icon on my notebook and told it to search for
devices within range. After watching the moving flashlight icon that told
me the search was in progress, I was elated to see the icon for my desktop
computer show up onscreen. The new hardware worked! Or so I thought.
However, when I tried to establish a Bluetooth network connection between
the two computers, it failed. No matter which computer I tried to use,
I got only error messages. Thus I could not explore any of the additional
features of the Bluetooth system. The Time-Warner Internet connection was
down, so I couldn’t consult the IOGEAR web site for help. The little booklet
that comes with the IOGEAR system is quite abbreviated. It tells you about
the main features, but contains no troubleshooting information or contact
numbers. At times, the descriptions of the software in the manual didn’t
exactly match what I saw onscreen, which typically happens when the manual
is sent to the printer before the software is totally finalized. Disappointing.
So under the time crunch of Clarke’s deadline, I have to sign off without
fully setting up the Bluetooth network. I have no doubt that with some
help from IOGEAR, which has a reputation for being very supportive, I could
have gotten everything running. But all this goes to show that setting
up this network is not as easy and straightforward as it need to be.
If you want to use the IOGEAR Bluetooth Networking Starter Kit by itself,
it could be useful. But since it doesn’t provide the range or speed of
a standard WiFi network, the latter seems to make more since, unless you
