-description: Azure IoT Central is an IoT application platform that simplifies the creation of IoT solutions. This guide describes how IoT devices connect to your IoT Central application. After a device connects, it uses telemetry to send streaming data and properties to report device state. Iot Central can set device state using writable properties and call commands on a device.
