2 KNX-RF evaluation package options
2.1 Package overview
KNX-RF package demonstrates:
•
S2-LP Sub-1GHz transceiver capabilities to support KNX-RF multi-protocol
• BlueNRG-2 BLE 5.1 system-on-chip capabilities to host KNX-RF stack and to run BLE and KNX-RF stack
with a single Cortex-M0 core (in combination with S2-LP )
• STM32L0 microcontroller capabilities to host KNX-RF stack (in combination with S2-LP )
The evaluation package provides software example projects (based on Keil IDE) to simulate:
•
KNX-RF switch application using BlueNRG-2 BLE 5.1 SoC. The application can be controlled by
smartphone
• KNX-RF light application (using VCOM)
Different KNX-RF topologies can be addressed using the evaluation package:
•
Standalone mode: point-to-point KNX-RF multi-communication
• KNX ETS5 PC application:
–
using Tapko Technologies TP/RF gateway (commercial devices)
– using Tapko Technologies USB dongle (evaluation device)
2.2 KNX-RF frameworks based on BlueNRG-2 BLE 5.1 system-on-chip
KNX-RF evaluation package features a framework based on BlueNRG-2 BLE SoC. It provides a KNX-RF switch
application example using BLE connectivity to control applications.
KNX-RF light application is simulated with another board receiving light control commands (on/off, dimming and
color control).
Each KNX-RF application involves a
BlueNRG-2 kit ( STEVAL-IDB008V2 with modifications) and an S2-LP
expansion board ( X-NUCLEO-S2868A2 or X-NUCLEO-S2868A1 with modifications).
