| 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 |
