__construct
Constructor.
data
array
Optional. Data for populating the Message object.
↳ id
string
The user-defined device identifier. The device ID must be unique within a device registry.
↳ name
string
The resource path name. For example, projects/p1/locations/us-central1/registries/registry0/devices/dev0
or projects/p1/locations/us-central1/registries/registry0/devices/{num_id}
. When name
is populated as a response from the service, it always ends in the device numeric ID.
↳ num_id
int|string
[Output only] A server-defined unique numeric ID for the device. This is a more compact way to identify devices, and it is globally unique.
↳ credentials
array< Google\Cloud\Iot\V1\DeviceCredential
>
The credentials used to authenticate this device. To allow credential rotation without interruption, multiple device credentials can be bound to this device. No more than 3 credentials can be bound to a single device at a time. When new credentials are added to a device, they are verified against the registry credentials. For details, see the description of the DeviceRegistry.credentials
field.
↳ last_heartbeat_time
Google\Protobuf\Timestamp
[Output only] The last time an MQTT PINGREQ
was received. This field applies only to devices connecting through MQTT. MQTT clients usually only send PINGREQ
messages if the connection is idle, and no other messages have been sent. Timestamps are periodically collected and written to storage; they may be stale by a few minutes.
↳ last_event_time
Google\Protobuf\Timestamp
[Output only] The last time a telemetry event was received. Timestamps are periodically collected and written to storage; they may be stale by a few minutes.
↳ last_state_time
Google\Protobuf\Timestamp
[Output only] The last time a state event was received. Timestamps are periodically collected and written to storage; they may be stale by a few minutes.
↳ last_config_ack_time
Google\Protobuf\Timestamp
[Output only] The last time a cloud-to-device config version acknowledgment was received from the device. This field is only for configurations sent through MQTT.
↳ last_config_send_time
Google\Protobuf\Timestamp
[Output only] The last time a cloud-to-device config version was sent to the device.
↳ blocked
bool
If a device is blocked, connections or requests from this device will fail. Can be used to temporarily prevent the device from connecting if, for example, the sensor is generating bad data and needs maintenance.
↳ last_error_time
Google\Protobuf\Timestamp
[Output only] The time the most recent error occurred, such as a failure to publish to Cloud Pub/Sub. This field is the timestamp of 'last_error_status'.
↳ last_error_status
Google\Rpc\Status
[Output only] The error message of the most recent error, such as a failure to publish to Cloud Pub/Sub. 'last_error_time' is the timestamp of this field. If no errors have occurred, this field has an empty message and the status code 0 == OK. Otherwise, this field is expected to have a status code other than OK.
↳ config
Google\Cloud\Iot\V1\DeviceConfig
The most recent device configuration, which is eventually sent from Cloud IoT Core to the device. If not present on creation, the configuration will be initialized with an empty payload and version value of 1
. To update this field after creation, use the DeviceManager.ModifyCloudToDeviceConfig
method.
↳ state
Google\Cloud\Iot\V1\DeviceState
[Output only] The state most recently received from the device. If no state has been reported, this field is not present.
↳ log_level
int
Beta FeatureThe logging verbosity for device activity. If unspecified, DeviceRegistry.log_level will be used.
↳ metadata
array| Google\Protobuf\Internal\MapField
The metadata key-value pairs assigned to the device. This metadata is not interpreted or indexed by Cloud IoT Core. It can be used to add contextual information for the device. Keys must conform to the regular expression [a-zA-Z][a-zA-Z0-9-_.+~%]+ and be less than 128 bytes in length. Values are free-form strings. Each value must be less than or equal to 32 KB in size. The total size of all keys and values must be less than 256 KB, and the maximum number of key-value pairs is 500.
↳ gateway_config
