 Hi everyone, I'm Anuja Upali, I'm Product Marketing Engineer with S3 Micro Electronics and today we are showing our Amazon Sidewalk demo. So Amazon Sidewalk is a low bandwidth long range communication protocol developed by Amazon. The main idea behind it is to create a secure community network where you can connect all your end devices to the internet for free and from nearly anywhere. It will use a small portion of the bandwidth which will be contributed by each user in the neighborhood. In the sidewalk network, we have sidewalk gateways. So these are Amazon Echo devices or Ring devices like doorbells or floodlights. So these will form a sidewalk network. Then we have sidewalk enabled end devices. So these are motion detectors or smart switches, smart lights. So these will send encrypted data over to the sidewalk gateways. They will in turn route it to the AWS server so that users can receive alerts and notifications regarding their devices. So Amazon Sidewalk uses both Bluetooth LE and sub gigahertz technologies. Bluetooth LE is used for short range communication whereas Laura and FSK custom modulation is used for long distance communication. So in this demo we are using STM32 WBA 52 and STM32 WL 55. STM32 WBA is our Bluetooth LE device. So we are using that device for commissioning and setting up the network with Amazon Echo. The STM32 WL 55 is our sidewalk enabled device. It supports both Laura and FSK modulation and in our demo this is sending all the data to Amazon Echo using Laura modulation. Amazon Echo in turn sends the data to AWS server. On the AWS server side we have created a simple dashboard where we can visualize and access this data. So here we can see the internal temperature of the microcontroller. We can see the LED status and we can see a variable counter to create a sine wave. So this is our Amazon Sidewalk demo.
