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.
