In today’s Internet of Everything era, cloud connectivity is the cornerstone of the development of many applications, including consumer electronics, home and building automation, smart appliances, handheld and wearable devices, toys and entertainment devices. No matter where the device is located, developers need to ensure the connectivity and security of remote devices, which brings challenges to the development of IoT applications.

‍‍‍‍‍‍In today’s Internet of Everything era, cloud connectivity is already the cornerstone of the development of many applications, including consumer electronics, home and building automation, smart appliances, handheld and wearable devices, toys and entertainment devices. No matter where the device is located, developers need to ensure the connectivity and security of remote devices, which brings challenges to the development of IoT applications. Although the demand scenarios for various applications are different, at the bottom layer, a certain connection method is required to securely connect the remote device to a certain background. In view of this, ST cooperates with Microsoft Cloud Azure to provide a variety of connection methods through device-cloud collaboration, enabling enterprises and developers to easily build IoT applications on the cloud, so as to better combine their own business scenarios and create industrial value. .

The third topic of wireless and cloud connection technology: STM32 IoT connection based on Microsoft cloud Azure

As a global partner of Microsoft Cloud Azure, ST, relying on the STM32 Cube ecosystem several years ago, developed an extension package for connecting to the Azure IoT Hub service, namely X-CUBE-AZURE, which contains the IoT SDK required for cloud connection, It can help developers connect STM32L4, F4, F7 and other development boards to Azure quickly. The currently supported connection methods include Ethernet, WiFi and cellular, and the cellular connection needs to be used together with the X-CUBE-CELLULAR extension package. If the developer also needs a secure firmware update (secure firmware update), it can be achieved through the X-CUBE-SBSFU extension package. The above expansion packs can be downloaded from the ST official website (www.st.com).

In addition to the above-mentioned method that developers are more familiar with, recently ST has also customized some connection demonstration development kits covering all levels together with the Microsoft Azure RTOS team, which can be used out of the box. The general structure is as follows:

These development kits include various interfaces, drivers, middleware, and cloud connection modules required for connection. Relying on the rich components of Azure RTOS, it is convenient for developers to freely mix and develop IoT applications more quickly. Please refer to the table below for the existing connection methods and development kits. In the future, ST will also maintain cooperation with the Azure RTOS team to launch more connection demonstration development kits.
