We have seen the steps to connect to an arbitrary BLE device using the TBluetoothLE component. For certain popular services, this can be even easier. Delphi comes with a number of components that simplify working with standard services such as, heart rate monitors, blood pressure monitors, and proximity sensors. There are also components available in GetIt for working with specific devices from specific vendors using not only BLE, but also other IoT protocols, such as Z-Wave.
Under the Tools menu, you can find the GetIt Package Manager. In order to use GetIt, you will need to have an internet connection. Over time, more and more new and updated software is available in GetIt. One of the available components in the IoT category is generic Heart Rate Monitor as shown in the following screenshot:
