Cloud IoT Core Java Samples

This folder contains Java samples that demonstrate an overview of the Google Cloud IoT Core platform.

Quickstart

Install the gCloud CLI as described in the device manager guide.
Create a PubSub topic:

gcloud beta pubsub topics create projects/my-iot-project/topics/device-events
Add the special account cloud-iot@system.gserviceaccount.com to that PubSub topic from the Cloud Developer Console or by using the helper script in the /scripts folder.
Create a registry:

gcloud alpha iot registries create my-registry
--project=my-iot-project
--region=us-central1
--pubsub-topic=projects/my-iot-project/topics/device-events
Use the generate_keys.sh script to generate your signing keys:

./generate_keys.sh
Create a device.

gcloud alpha iot devices create my-java-device
--project=my-iot-project
--region=us-central1
--registry=my-registry
--public-key path=rsa_cert.pem,type=rs256
Connect a sample device using the sample app in the mqtt_example folder.
Learn how to manage devices programatically with the sample app in the manager folder.
