Description
The STSW-S2LP-KNX-DK is an evaluation package based on the S2-LP highperformance ultra-low power RF transceiver and BlueNRG-2 very low power
Bluetooth Low Energy (BLE) system-on-chip. It is designed to evaluate KNX-RF
communication in the 868 MHz license-free ISM band.
The STSW-S2LP-KNX-DK package provides a software framework including KNX
Tapko technologies stack (evaluation version). The package includes application
examples which allow simulating point-to-point KNX-RF protocol communication andare compliant with the KNX ETS tool.
