How-to guides

• Getting started

  Set up your project and environment for Cloud IoT Core and learn about key concepts.

• Creating registries and devices

  Create device registries and set up devices within them.

• Using gateways

  Create gateways and configure them to relay messages between non-gateway devices and Cloud IoT Core.

• Using the MQTT bridge

  Connect devices to Cloud IoT Core with the industry-standard MQTT protocol.

• Using the HTTP bridge

  Use connectionless HTTP to publish device telemetry, update device configuration, and report device state to Cloud IoT Core.

• Configuring devices and getting state

  Update device configuration and get the state reported by the device.

• Sending commands to devices

  Send one-time directives to devices.

• Managing credentials

  Create public/private key pairs for devices, generate JSON Web Tokens, add certificates to registries, and authenticate applications.

• Access control

  Use Identity and Access Management to control access to devices.

• Logging and monitoring

  Use Stackdriver to monitor Cloud IoT Core resources and view audit logs and device logs.

• Error handling

  Understand Cloud IoT Core errors and how to handle them using approaches like exponential backoff.
