M2M Communications

Overview

Subscription: IoTDA supports MQTT-based message communication between devices. By creating a rule on the IoTDA console, or calling IoTDA APIs to configure and activate rules, you can obtain messages reported by devices. For details about the involved APIs, see Creating a Rule Triggering Condition, Creating a Rule Action, and Modifying a Rule Triggering Condition. Device subscription supports only message reporting.

Push: After the subscription is successful, the platform pushes messages reported by devices to the specified MQTT topic. After devices are connected to the platform, you can subscribe to the topic to receive data for inter-device message communications. The following figure shows the message communications process between devices.
