Cloud connectivity allows you to easily collect data and take actions on microcontroller-based devices for use in IoT applications and with other AWS cloud services. You can connect FreeRTOS devices to AWS IoT Core using MQTT-based messaging or HTTP. MQTT is a lightweight protocol with a small footprint, enabling efficient communication for constrained, microcontroller-based devices. FreeRTOS facilitates easy onboarding with standard, vendor-independent library interfaces. MQTT is a lightweight protocol with a small footprint, enabling efficient communication for constrained, microcontroller-based devices. Cloud connectivity allows devices like smart electricity meters to send back information on consumption and analyze that data with other AWS services like AWS IoT Analytics.
