Fearless Cross-Platform Development with Delphi

By: David Cornelius

Overview of this book

Delphi is a strongly typed, event-driven programming language with a rich ecosystem of frameworks and support tools. It comes with an extensive set of web and database libraries for rapid application development on desktop, mobile, and internet-enabled devices. This book will help you keep up with the latest IDE features and provide a sound foundation of project management and recent language enhancements to take your productivity to the next level. You’ll discover how simple it is to support popular mobile device features such as sensors, cameras, and GPS. The book will help you feel comfortable working with FireMonkey and styles and incorporating 3D user interfaces in new ways. As you advance, you’ll be able to build cross-platform solutions that not only look native but also take advantage of a wide array of device capabilities. You’ll also learn how to use embedded databases, such as SQLite and InterBase ToGo, synchronizing them with your own custom backend servers or modules using the powerful RAD Server engine. The book concludes by sharing tips for testing and deploying your end-to-end application suite for a smooth user experience. By the end of this book, you’ll be able to deliver modern enterprise applications using Delphi confidently.

Learning about low-energy Bluetooth

With our understanding of what it takes to use Classic Bluetooth, we can build on that to understand the newer version, Bluetooth Low Energy (BLE), also known as Smart Bluetooth. Here are the differences:

  • BLE works well with low-powered devices.
  • BLE runs on Macs and Android devices like its classic predecessor, but also on iOS devices; for Windows, you need Windows 10 or newer.
  • BLE publishes discoverable services, just like Classic Bluetooth, but there is no need for pairing—clients simply connect and start using a service.
  • BLE's published services are defined with a profile, rather than just the raw stream of bytes that you get with Classic Bluetooth. A widely used profile is the Generic Attribute Profile (GATT).
  • BLE is primarily used for information reporting from IoT devices such as heart rate or blood pressure monitors, or cycle speed and cadence measuring, but is not limited to one-way communication.
