An open standard for residential and commercial building automation, the KNX communication protocol offers both wired and wireless node topologies ensuring high interoperability between devices and systems without the need for a central gateway.
The S2-LP - high performance ultra-low power RF transceiver- and the BlueNRG-2 - very low power Bluetooth Low Energy (BLE) system-on-chip - are certified KNX-RF Multi compliant and are able to handle several RF channels simultaneously (to reduce interference issues with other sub-1GHz devices) as well as reduce the power consumption of battery-operated applications that is key in wireless systems.
ST's KNX-RF portfolio provides a cost-optimized, power-efficient solution with dual RF connectivity (Bluetooth LE and KNX-RF) with only a two-chip configuration.
The STSW-S2LP-KNX-DK is an evaluation package based on the S2-LP and BlueNRG-1, designed to evaluate KNX-RF communication in the 868 MHz license-free ISM band.
To help engineers working on applications including KNX-RF gateways and wireless switches with smartphone connectivity get their solution to market quicker, ST offers a selection of KNX evaluation boards and development kits.
