IoT clients

The Internet of Things (IoT) describes connected end-node devices that collect, process and exchange data. Such devices are frequently connected via the Internet to a cloud service that provides processing power, data analytics, and storage capabilities. An IoT client is a software interface which runs in the IoT end-note device and establishes the connection to a cloud service.

Many cloud service providers offer open-source software that implements an IoT client for an embedded system. Arm adopted these clients for using the reliable MDK-Middleware network component for communication with the cloud service. Alternatively, you can use WiFi devices that are supported by a CMSIS-WiFi driver. The following IoT clients are supported:

For the above mentioned cloud providers, an IoT client is available. The end node application uses this client, connected to the MDK-Middleware networking stack running on a CMSIS-RTOS v2 based real-time operating system.

A simplified software flow can be described as follows:

1. The application initializes and starts the real-time operating system.
2. It initializes the network stack which needs to be active before the next step.
3. The IoT client is used through its API.
