Product overview


The STSW-S2LP-KNX-DK is an evaluation package based on the S2-LP high performance 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 and are compliant with the KNX ETS tool.

This software combines KNX-RF Sub-1 GHz protocol and Bluetooth LE communication in one single application (using S2-LP and BlueNRG-2).
