  1. Indicates the version of Bluetooth Core specification that was first introduced.
  2. CSA: Core Specification Addendum

Bluetooth Low Energy protocol stack basic package provides an application demo project that shows an example of protocol stack integration into your project and an example of user application implementation.
It notifies pressing push switch of Renesas evaluation board by Bluetooth communication and controls blinking of LED.
Control from a smartphone is also possible by using a general purpose BLE communication smartphone app such as GATTBrowser.
