The types of BLE devices and applications most relevant to iOS programming fall into three main categories:
- Peripheral devices with iOS apps
- In this category, BLE peripheral devices and sensors are paired with corresponding iOS apps—for example, a bicycling power and cadence meter that uses the iPhone to display and record data.
- iBeacon devices
- The iBeacon is a broadcast-only device that uses BLE advertising (see Advertising and Scanning) to augment navigation indoors, where GPS signals and cell phone towers typically can’t penetrate, to provide location services to iOS devices (and also Android devices).
