BLE or Bluetooth Low Energy (or Bluetooth 4.0) is a new standard in Bluetooth technology that allows devices to send and receive data while using only a small amount of energy. This allows Bluetooth devices most of the benefits in a Bluetooth connection while lowering the power draw significantly.
Beaconizer turns any BLE enabled iOS device in to a iBeacon. It can operate in a broadcaster mode (as an iBeacon) or as a receiver (application). The application can be used in integration testing and development of proximity based services.
