 While the discovery latencies of BLE can be approximated by models for purely periodic interval-based protocols, the random delay added to each advertising interval and the three-channel discovery can cause deviations from these predictions, or potentially lead to unbounded latencies for certain parametrizations.Bluetooth LE comes with very low, and in many cases broken security.BTLE or Bluetooth Smart, is a new modulation mode and link layer packet format targeting low powered devices and is found in recent high-end smart phones, sports devices, sensors, and will soon appear in many medical devices.
