  • Bluetooth Low Energy (Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG) aimed at novel applications in the healthcare, fitness, beacons, security, and home entertainment industries.
  • Step 5: Find your BLE device and connect to it. To see all available devices (peripherals) to connect with, you can listen for discovered peripherals with didDiscoverPeripheral.
  • Passing data between view controllers inside a tab bar controller In the cases we saw above, the source view controller gets a reference to the destination view controller somehow. There is a special case where this does not happen: when you use a tab bar controller.
  • On iOS the whole BLE connection management is maintained by the operating system. That means that no single application "owns" a connection. All BLE functionality is multiplexed to allow more than one application to gain access to centrals and peripherals.
