Cloud IoT API v1 - Package cloud.google.com/go/iot/apiv1 (v0.77.0)

Package iot is an auto-generated package for the Cloud IoT API.

Registers and manages IoT (Internet of Things) devices that connect to the Google Cloud Platform.

Use of Context

The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

For information about setting deadlines, reusing contexts, and more please visit pkg.go.dev/cloud.google.com/go.

Functions

func DefaultAuthScopes

func DefaultAuthScopes() []string

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

DeviceIterator

type DeviceIterator struct {

	// Response is the raw response for the current page.
	// It must be cast to the RPC response type.
	// Calling Next() or InternalFetch() updates this value.
	Response interface{}

	// InternalFetch is for use by the Google Cloud Libraries only.
	// It is not part of the stable interface of this package.
	//
	// InternalFetch returns results from a single call to the underlying RPC.
	// The number of results is no greater than pageSize.
	// If there are no more results, nextPageToken is empty and err is nil.
	InternalFetch func(pageSize int, pageToken string) (results []*iotpb.Device, nextPageToken string, err error)
	// contains filtered or unexported fields
}

DeviceIterator manages a stream of *iotpb.Device.

func (*DeviceIterator) Next

func (it *DeviceIterator) Next() (*iotpb.Device, error)

Next returns the next result. Its second return value is iterator.Done if there are no more results. Once Next returns Done, all subsequent calls will return Done.

func (*DeviceIterator) PageInfo

func (it *DeviceIterator) PageInfo() *iterator.PageInfo

PageInfo supports pagination. See the google.golang.org/api/iterator package for details.

func (c *DeviceManagerClient) SendCommandToDevice(ctx context.Context, req *iotpb.SendCommandToDeviceRequest, opts ...gax.CallOption) (*iotpb.SendCommandToDeviceResponse, error)

SendCommandToDevice sends a command to the specified device. In order for a device to be able to receive commands, it must:

be connected to Cloud IoT Core using the MQTT protocol, and

be subscribed to the group of MQTT topics specified by /devices/{device-id}/commands/#. This subscription will receive commands at the top-level topic /devices/{device-id}/commands as well as commands for subfolders, like /devices/{device-id}/commands/subfolder. Note that subscribing to specific subfolders is not supported. If the command could not be delivered to the device, this method will return an error; in particular, if the device is not subscribed, this method will return FAILED_PRECONDITION. Otherwise, this method will return OK. If the subscription is QoS 1, at least once delivery will be guaranteed; for QoS 0, no acknowledgment will be expected from the device.
