1. Introduction
WIDCOMM's BTW-CE is a complete communication software solution for integrating
Bluetooth wireless technology into the Pocket PC® operating system. It has all the necessary
protocol and driver software to enable PC OEMs to bring wireless devices to market quickly
and efficiently.
The BTW-CE DK product for ordinary Pocket PC devices consists of three parts:
• The base software CD which includes drivers, protocol stacks, support tools, and
documentation. Installing this CD provides the Microsoft Windows operating system
extensions that will allow your Pocket PC device to communicate using Bluetooth
wireless technology.
• The Software development kit containing programming APIs, sample applications, and
programming documentation. This is available as a download from the technical
support section of www.widcomm.com.
circuitry.
The Compaq iPAQ H3850 differs from the iPAQ H3870 since it does not include an integrated
Bluetooth adapter and software. It also differs from the other members of the 36XX, 37XX,
and H38XX family in that the first available COM port that is assigned to an external Bluetooth
adapter is COM5 rather than COM4. This means that when you install the BTW-CE 1.0.0.11
software from WIDCOMM, the software will be improperly configured and will not run.
This document will allow owners of the Compaq H3850 Pocket PC to reconfigure their device
so that the BTW-CE 1.0.0.11 software from WIDCOMM will operate properly on their
device.
IMPORTANT: This document covers only the iPAQ H3850 and this CF card .
These instructions may not apply to a CF card from another manufacturer.
IMPORTANT: The procedures outlined in this document cover only the 1.0.0.11
release of the BTW-CE software.
IMPORTANT: BTW-CE 1.2.0 will not correctly auto-detect the COM port settings
of the CF card on an iPAQ H3850 and will not set up the device correctly. There is
no workaround. This problem is currently under investigation. Contact
WIDCOMM, Inc. Technical Support for a status report on this issue.
2. Symptoms of the Failure
You can tell if your software is configured correctly by attempting to run CEDemeExplorer.
The device should initialize correctly as shown in Figure 1 below. If the software is not
configured correctly, you will see the display shown in Figure 2.
3. A Quick Overview of the Procedure
You should follow all of the steps outlined in this document in order to successfully configure
your BTW-CE on your Compaq H3850. Here is a quick overview of the actions that you will
take:
• Obtain and install a registry editor for your Pocket PC device.
• Install the CF Bluetooth Adapter on your unit.
• Install the WIDCOMM BTW-CE software on your unit.
• Using the registry editor, verify the actual COM port that is assigned to the CF Bluetooth
Adapter
• If the port was COM5, leave the registry file intact. Otherwise, correct the registry file.
• ActiveSync the registry file to your iPAQ 3850 and use your registry editor to import it.
• Soft reset the iPAQ
• Attempt to run CEDemoExplorer.
If CEDemoExplorer runs successfully, then your device is working properly and you will be
ready to begin using your BTW-CE software and DK.
4. Reconfiguring your Device
This problem is due to the fact that the iPAQ 3850 assigns a different COM port to the
CF Bluetooth Adapter than the other iPAQ models.
