Open.RF is a free and easy to use software library for the development of best in class RF applications. The first library available is osxSmartConnPS, an implementation for Bluetooth low energy slave profiles running on the STM32 for ST's BlueNRG Bluetooth Low Energy device.

The software comes with examples of implementation of the drivers running on the Bluetooth Low Energy BlueNRG Nucleo expansion board (X-NUCLEO-IDB04A1),  when connected to a STM32F4 Nucleo board (NUCLEO-F401RE) or a STM32L0 Nucleo Board (NUCLEO-L053R8).

When installed on your pc, it must be activated through a licensing wizard tool.
