Message Reporting Overview

Introduction

Message reporting is a method by which a device directly sends data to the cloud and forwards the data to applications or other Huawei Cloud services through data forwarding. The platform does not parse or store the messages reported by devices. In this case, a product model is not required.

Scenarios

• The platform does not parse or store the messages reported by devices.
• Data needs to be forwarded to other Huawei Cloud services for storage and processing based on data forwarding rules.

Constraints

• Maximum size of a single message: 1 MB.
• The maximum bandwidth of a single MQTT connection is 1 MB/s.
• A single MQTT connection supports a maximum of 50 upstream messages per second (one request is considered as one message).
