 Today we will present you a demonstration about KNX ecosystem using ST product. So I'm Philippe Simonnet, part of ST EMEA application support team, and I let Didier introduce yourself. Yes, my name is Didier Wan, so I am part also of the application team based in France, and I am focusing on the analog product and especially on ST KNX product, which is the solution for the wire bus for KNX. So the purpose of the demonstration will be both explaining all ST KNX will be the ST solution for KNX bus ecosystem, and then the second part will be we present KNX RF, YRS extension to KNX ecosystem. Here we have a simulation of a very simple KNX network. On the left we have a board with a simple switch, which is connected to the KNX bus through this KNX device. And we have also an evaluation board on which we'll find the ST KNX chipsets and all the staff around to make some some some debug. And on the other side of the bus, so we can imagine that we have a building and these two places are connected through this cable. And on the other side of the demonstration, we have one module which is used to program the different devices. So you need one module when you install the network after you don't need it anymore. You have a power supply module which will provide the power to the KNX bus and which will in fact power supply the complete devices. And on this demonstration we have also a switch which will make the communication between the KNX bus and the 220 AC network, so to control the bulb lamp. And on the evaluation board, we have added a plugging a board extension on which there is some LED so which will be controlled by the other head as I will show you. So the feature which are inside this demonstration on the first board I can decide to switch on the LED of the second board. I can increase the luminosity of the LED and decrease it and I can change the color of the LED by another button. All these features have been programmed through the ETS tool. We have programmed another feature inside this simple switch. If you switch on the bulb lamp and if you switch on also the LED, we have programmed the switch to be able to switch off all the all the lamps, the LED and the bulb, like a central protocol as you can see. So thanks to DDA who explained all STKNX chipset is working with STKNX kit. Now we can show an extension of KNX bus ecosystem to KNX RF, wireless ecosystem. So in the demonstration we can add a KNX TP-RF gateway that is extending the network to wireless system. So using KNX RF sub-gigarats connectivity. The wireless extension of KNX ecosystem is done using two kinds of ST solution. First the blue energy dash 2 BLE system on chip using that kit, blue energy dash 2 kit and the sub-gigarats connectivity for KNX RF connectivity using S2LP transceiver using S2LP kits. The purpose then is to provide of course KNX RF connectivity using using sub-gigarats band and the BLE connectivity is a plus because we can provide an additional connectivity using 2.4 gigahertz band and smart phone smart phone connectivity in order to connect device to your application on a dedicated application on smartphone. So STKNX RF multi certified solution has been done using S2LP transceiver board with integrated balloon inside and blue energy dash 2 evaluation kit. So using that demonstration we plug the S2LP expansion board on top of BLE board for push button application connected to smartphone and for simulation of KNX RF light application we are using the same setup but we are adding a KNX nucleo with a light driver on top. With the ETS tool I'm able to control and to configure all my KNX network both KNX bus devices and KNX RF devices. So with ETS then I'm able to download configuration of the push button application for example here by downloading the configuration from the tool and I'm able to do the same for KNX RF application that is simulating a LED light application. So using BLE application I'm able to control both KNX RF light application from this push button application and I'm able also to control KNX bus light application. To do so here is the demonstration with my application on my smartphone using BLE connectivity between smartphone and push button application I'm saying that okay I want to switch on or switch off that KNX RF light this is done using so that application here I'm switching on and I can switch off that application also but I'm also able to control KNX bus base device using that gateway which is the bridge between KNX RF connectivity and KNX bus connectivity so to do so I'm selecting another channel to control another light which is this one and I'm able to switch on and switch off the light on is using the same way same application with BLE application we can not only control switch on and switch off of application but also the dimming or color selection of KNX RF light application for example I can control the dimming using BLE apps like this but I can control also the color so if I select green color here you can see the color is changing or red color for example like this or purple let's say or come back to blue color as a conclusion today we have demonstrated that ST is able to provide solution for both KNX bus bus solution using KNX bus twisted pair solution and KNX RF solution like s2lp sub gigahertz from steve but also we are able to provide enhancement of wireless connectivity thanks to BLE to show that a very simple push button application could be improved with BLE connectivity and thanks to smartphone application
