High-Level Communications

Exploring Palm OS®

This book describes the portions of Palm OS® that are involved in high-level communications functions and are not transport specific. These include:

  • Connection Manager, which provides a central mechanism for managing Palm OS communications connections
  • Exchange Manager, which supports sending and receiving typed data objects
  • Personal Data Interchange, which facilitates the exchange of information using standard vObjects

This book focuses on the high-level communications managers. It does not cover lower-level transport-specific managers. For information on these managers, see Exploring Palm OS: Low-Level Communications.

Who Should Read This Book ^TOP^

You should read this book if you are a Palm OS software developer and you want to do one of the following:

  • Establish a communications connection so that your application can send or receive data.
  • Create or configure communications profiles, which link lower-level communications components, called plug-ins, into a complete path that can be used to establish a connection.
  • Send or received typed data objects from an application without having to manage the communications connection. The Exchange Manager manages all communications details for you.
  • Register your application to receive data objects of a particular type when they arrive on the handheld device.
  • Enable your application to read vObjects from an input stream or write vObjects to an output stream. The vObject standard allows applications to exchange standardized data types such as vCard (virtual business cards) and vCal (calendar and schedule information).

The APIs described in this book are optional, though they can greatly enhance the capabilities of an application. Beginning Palm OS developers may want to delay reading this book until they gain a better understanding of the fundamentals of Palm OS application development. Instead, consider reading Exploring Palm OS: Programming Basics to gain a good understanding of event management and Exploring Palm OS: User Interface to learn about events generated by standard UI controls. Read this book when you find that you need to enable your application with communications functionality.

The Exploring Palm OS Series ^TOP^

This book is a part of the Exploring Palm OS series. Together, the books in this series document and explain how to use the APIs exposed to third-party developers by the fully ARM-native versions of Palm OS, beginning with Palm OS Cobalt. Each of the books in the Exploring Palm OS series explains one aspect of the Palm operating system and contains both conceptual and reference documentation for the pertinent technology.

As of this writing, the complete Exploring Palm OS series consists of the following titles:

  • Exploring Palm OS: Programming Basics
  • Exploring Palm OS: Memory, Databases, and Files
  • Exploring Palm OS: User Interface
  • Exploring Palm OS: User Interface Guidelines (coming soon)
  • Exploring Palm OS: System Management
  • Exploring Palm OS: Text and Localization
  • Exploring Palm OS: Input Services
  • Exploring Palm OS: High-Level Communications
  • Exploring Palm OS: Low-Level Communications
  • Exploring Palm OS: Telephony and SMS
  • Exploring Palm OS: Multimedia
