Core Bluetooth
Core Bluetooth is an Apple framework that enables iOS, iPadOS, macOS, watchOS, and tvOS apps to communicate with Bluetooth Low Energy (BLE) devices. It provides APIs for discovering, connecting to, and exchanging data with BLE peripherals such as fitness trackers, smart home devices, and medical sensors. The framework handles the underlying Bluetooth protocol details, allowing developers to focus on app-level functionality.
Developers should learn Core Bluetooth when building apps that need to interact with BLE devices, such as health monitors, IoT gadgets, or custom hardware accessories. It's essential for creating apps that leverage wireless connectivity for data transfer, remote control, or sensor integration in Apple's ecosystem. Use cases include fitness apps syncing with heart rate monitors, home automation apps controlling smart lights, or medical apps reading data from glucose meters.
