More and more functionalities of real devices include the need for interactions with other smart devices or sensors. Bluetooth technology is the connectivity standard for these kinds of interactions: it implements a local networking facility connecting different nearby devices.
In this section, we'll learn about Bluetooth technology and the support built into the FMX framework. For example, we'll learn how to scan for other Bluetooth-enabled devices, along with how to connect to or interact with them.
Bluetooth is a wide-ranging technology that has been around for a few years now. The original Bluetooth has been widely adopted and can be used in a multitude of applications (desktop and mobile). To provide coverage of Bluetooth specifications is way beyond the scope of this book, but I want to show you how Delphi can be used to target a specific slice of the Bluetooth family, that is, Bluetooth Low Energy (BLE) devices.
The Delphi...
