.. _google-iot-mqtt-sample: Google IOT MQTT Sample ###################### Overview ******** This sample application demonstrates a "full stack" application. This currently is able to - Acquire a DHCPv4 lease. - Connect to an SNTP server and acquire current time - Establish a TLS connection with the Google IOT Cloud servers - Publish data to the Google IOT Cloud - Send/Receive keep alive / pings from cloud server The source code for this sample application can be found at: :zephyr_file:`samples/net/google_iot_mqtt`. Requirements ************ - Entropy source - Google IOT Cloud account - Google IOT Cloud credentials and required information - Network connectivity Building and Running ******************** This application has been built and tested on the NXP FRDMK64F. RSA or ECDSA certs/keys are required to authenticate to the Google IOT Cloud. The application includes a key creation script. Run the ``create_keys.py`` script in the ``samples/net/google_iot_mqtt/src/private_info/`` directory. Users will also be required to configure the following Kconfig options based on their Google Cloud IOT project: - CLOUD_CLIENT_ID - created from <telemetry>/<region>/registries/<registry name>/devices/<device name> - CLOUD_AUDIENCE - created from telemetry without projects on front - CLOUD_SUBSCRIBE_CONFIG - created from /devices/<device name>/config - CLOUD_PUBLISH_TOPIC - created from /devices/<device name>/state See `Google Cloud MQTT Documentation <https://cloud.google.com/iot/docs/how-tos/mqtt-bridge>`_.
