Core Beacons is a development tool for iOS. Core Beacons lists the advertisements of Bluetooth LE devices in range, as made available to applications by the CoreBluetooth API. Core Beacons lets you explore your "Bluetooth environment" and shows how your iOS device presents this environment to applications. Core Beacons displays general CoreBluetooth information and, if advertised by a device, service and/or manufacturer-specific data. Detailed parsing support is available for • ruuvi sensor tags: • Format 3 (raw data v1) • Format 4 (sensor data encoded in Eddystone URL) • Format 5 (raw data v2) • Eddystone: UID, URL (incl. Physical Web) & TLM frame types • mijia temperature & relative humidity sensor beacons (as far as this protocol is documented) • AltBeacon Core Beacons may be most useful when working with "beacon" type BLE devices.
