2.3 KNX-RF frameworks based on STM32L0 microcontroller
Another framework is based on STM32L0 Cortex-M0+ microcontroller. It provides a simple KNX-RF switch
application (VCOM required to simulate buttons) and KNX-RF light application is simulated with another board
receiving light control commands (on/off, dimming and color control).
Each KNX-RF application involves an STM32L0 development board (
NUCLEO-L073RZ ) and an S2-LP expansion
board ( X-NUCLEO-S2868A2 or X-NUCLEO-S2868A1 with modifications).

2.4 KNX-RF point-to-point topology based on BlueNRG-2 evaluation kits
This point-to-point topology demonstrates KNX-RF multi-communication without KNX infrastructure (based on
wired KNX devices).
It also demonstrates extra connectivity via smartphone (only the KNX-RF switch application is controlled via BLE).

2.5 KNX-RF point-to-point topology based on STM32L0 development boards
This point-to-point topology demonstrates KNX-RF multi-communication without KNX infrastructure (based on
wired KNX devices).
It is designed for STM32 general purpose microcontrollers belonging to
STM32L0 family.
