SDK Usage

Introduction

The Huawei Cloud Device Python SDK provides abundant demo code for devices to communicate with the platform and implement device, gateway, and over-the-air (OTA) services. The SDK greatly simplifies device development and enables quick access to the platform. This section uses an example to describe how to use the SDK to quickly connect MQTT devices to the Huawei Cloud IoT platform. For details, see IoT Device Python SDK.

Requirements

  • Python 3.11.4 has been installed.
  • The third-party class library paho-mqtt 2.0.0 has been installed.
  • The third-party class library schedule 1.2.2 has been installed.
  • The third-party class library APScheduler 3.10.4 has been installed.
  • The third-party class library requests 2.32.2 has been installed (optional, used in the demo of gateway and child device management).
  • The third-party class library tornado 6.3.3 has been installed (optional, used in the demo of gateway and child device management).

You can run requirement/install_requirements.py to install dependencies.
