<pre>Creates a device in a device registry.

parent: string, Required. The name of the device registry where this device should be created.
For example,
`projects/example-project/locations/us-central1/registries/my-registry`. (required)
body: object, The request body.
The object takes the form of:
{ # The device resource.
&quot;credentials&quot;: [ # 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.
{ # A server-stored device credential used for authentication.
&quot;expirationTime&quot;: &quot;A String&quot;, # [Optional] The time at which this credential becomes invalid. This
# credential will be ignored for new client authentication requests after
# this timestamp; however, it will not be automatically deleted.
&quot;publicKey&quot;: { # A public key format and data. # A public key used to verify the signature of JSON Web Tokens (JWTs).
# When adding a new device credential, either via device creation or via
# modifications, this public key credential may be required to be signed by
# one of the registry level certificates. More specifically, if the
# registry contains at least one certificate, any new device credential
# must be signed by one of the registry certificates. As a result,
# when the registry contains certificates, only X.509 certificates are
# accepted as device credentials. However, if the registry does
# not contain a certificate, self-signed certificates and public keys will
# be accepted. New device credentials must be different from every
# registry-level certificate.

that this is a continuation of a prior `ListDevices` call and
the system should return the next page of data.
fieldMask: string, The fields of the `Device` resource to be returned in the response. The
fields `id` and `num_id` are always returned, along with any
other fields specified.
pageSize: integer, The maximum number of devices to return in the response. If this value
is zero, the service will select a default size. A call may return fewer

indicates that more data is available.

IDs: 10,000. (repeated)
gatewayListOptions_associationsDeviceId: string, If set, returns only the gateways with which the specified device is

<div class="method">
<code class="details" id="sendCommandToDevice">sendCommandToDevice(name, body=None, x__xgafv=None)</code>
<pre>Sends a command to the specified device. In order for a device to be able
to receive commands, it must:
1) be connected to Cloud IoT Core using the MQTT protocol, and
2) 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.
Args:
name: string, Required. The name of the device. For example,
`projects/p0/locations/us-central1/registries/registry0/devices/device0` or
`projects/p0/locations/us-central1/registries/registry0/devices/{num_id}`. (required)
body: object, The request body.
The object takes the form of:
{ # Request for `SendCommandToDevice`.
&quot;subfolder&quot;: &quot;A String&quot;, # Optional subfolder for the command. If empty, the command will be delivered
# to the /devices/{device-id}/commands topic, otherwise it will be delivered
# to the /devices/{device-id}/commands/{subfolder} topic. Multi-level
# subfolders are allowed. This field must not have more than 256 characters,
# and must not contain any MQTT wildcards (&quot;+&quot; or &quot;#&quot;) or null characters.
&quot;binaryData&quot;: &quot;A String&quot;, # Required. The command data to send to the device.
}
x__xgafv: string, V1 error format.
Allowed values
1 - v1 error format
2 - v2 error format
Returns:
An object of the form:
{ # Response for `SendCommandToDevice`.
