-
Install the dependencies
pip install -r requirements.txt
The following snippet summarizes usage:
cloudiot_mqtt_example.py [-h]
--project_id PROJECT_ID
--registry_id REGISTRY_ID
--device_id DEVICE_ID
--private_key_file PRIVATE_KEY_FILE
--algorithm {RS256,ES256}
[--cloud_region CLOUD_REGION]
[--ca_certs CA_CERTS]
[--num_messages NUM_MESSAGES]
[--mqtt_bridge_hostname MQTT_BRIDGE_HOSTNAME]
[--mqtt_bridge_port MQTT_BRIDGE_PORT]
For example, if your project ID is blue-jet-123, the following example shows
how you would execute using the configuration from the MQTT code samples guide:
python cloudiot_mqtt_example.py \
--registry_id my-registry \
--project_id=blue-jet-123 \
--device_id my-python-device \
--algorithm RS256 \
--private_key_file ../rsa_private.pem
