The following document will help you to setup Bluetooth
synchronization using ActiveSync 3.7.1 with Microsoft Bluetooth Wireless
Transceiver. This article provides an illustrated, step-by-step
procedure to get it working. This article can be referred for
other Bluetooth software as well but the steps might vary a little
to setup the virtual COM port. The crucial step while setting up a
Bluetooth connection is to ensure that the COM port assigned is not
greater than COM 9. The reason being - ActiveSync does not support higher COM ports.
For more information on how you can reassign the COM ports, please refer
My sincere thanks to Chris De Herrera for allowing me to host my articles
on Pocket PC FAQ (formerly CEWindows.NET).
Finally, it is possible to synchronize your Pocket PC with Microsoft's Wireless Transceiver shipped with their
Optical Wireless IntelliMouse Explorer and Wireless Optical Desktop for Bluetooth.
This was not possible earlier due to lack of support for the serial
profile. The illustrations below gives a detailed instruction of
how I have setup my iPAQ 4155 for Bluetooth synchronization.
How to set it up:
- Step 1: Install Service Pack 2 for Windows XP
First, you need to download the Service Pack 2 (SP2) for Windows
XP since this has various enhancements for Bluetooth standard.
You can install it by visiting the following Windows update Web site
After installation, you need to restart the computer.
- Step 2: Setting up the Bluetooth on the Desktop and the
Assuming you have already installed and
established a partnership with your Desktop computer, Clicking File
-> Connection Settings will show the following as your COM port
settings. Or else it is recommended that you connect your
Pocket PC either using serial or USB connection and establish a
partnership before proceeding to establish a Bluetooth connection.
You will first need to Add the Pocket PC device. This can
be down by right-clicking the Bluetooth icon running in the system
tray or else Click on Start -> Control Panel -> Printer & Other
Hardware and click the Bluetooth Devices and click "Add a Bluetooth
The following screen will appear. Now you need to
turn on the Bluetooth signal on your Pocket PC, check the option on
the screen below and click the Next button:
The Wizard will search for the device and display it
as shown below:
Select the device and click next and the following
screen will appear. If you want to setup a passkey select the
option and enter the desired key:
In this example, I have set the passkey as "111" and
clicked the next button:
At this instance, you need to check your Pocket PC
and enter the passkey. This needs to be done quickly or else
you will encounter the following screen. If you do, simply go
back and perform the steps once again:
After you enter the passkey on your Pocket PC, the computer will
detect the Pocket PC. You will notice a bubble on your task bar as
shown below followed by the Wizard confirmation of a successful
connection being established:
Next step is to check the COM ports that it has got
Click the COM Ports tab and note the COM ports that
it is using. If the COM ports used by the Pocket PC are
higher then COM port 9, then you will need to assign it manually
since ActiveSync will support COM ports between 1 and 9 only:
To re-assign the COM port, go to the Device Manager
and click and expand the Ports (COM & LPT) listing as shown below:
To assign a COM port number, you will need to
rearrange the COM ports whereby the Bluetooth virtual COM port is
assigned a number in the supported range. You might need to
uninstall some serial hardware or software to be able to do so.
Refer to the following MSKB article to remove all false virtual COM
ports via Device Manager ---
Once it displays
all the COM ports, you can proceed to uninstall the blocked ports.
The other way is to manually set the port number but this might
interfere with the functioning if the COM port is being used by
another device. If you are sure the COM port is not being used
by the other device, then you can set it up manually as explained in
the following screen.
The, COM port 26 (Incoming) is going to be
assigned COM port 8. Right-click the Device Manager entry for
COM26 and click Properties and select the Port Settings tab.
Next click the Advanced button and select the COM
Port Number that you need to assign from the list box at the end of
Click Yes and proceed to do the same for the other
COM port. In our example (COM25 is to be set as COM 6).
After this is done, Click Action -> Scan for
Hardware changes on your Device Manager window and you will see the
COM ports reflecting the changes you have made. Next go to the
COM port listing again in the Bluetooth Devices list as explained
earlier and verify that the COM ports are reflecting the changes.
Once this is done, go to your Pocket PC and start
the Bluetooth Manager. Tap New and select the "ActiveSync via
Bluetooth" option. Follow the instructions on the screen and once
your computer is listed, select the device and create a short-cut
icon for the connection. Next time you want to connect using
Bluetooth, all you have to do is tap the short-cut icon and choose Connect.
On your computer, click on the Devices tab on the same dialog as
shown below and select the Pocket PC and click Properties and then
click the Services tab and ensure the Serial port service is
Open ActiveSync on your Desktop and attempt to connect via your Pocket PC short-cut. You
should have a successful connection. Enjoy synchronizing via Bluetooth with your Microsoft Bluetooth Transceiver !!!
