This page explains how to create, configure, and manage gateways.

Creating or editing a gateway

You can create a gateway or edit an existing one using console, or gcloud. After you create a gateway, you can't change it to a non-gateway device. Make sure Ensure you've created a registry and a device key pair before completing the steps in this sectionbelow.

Console

...

Create a new gateway

...

1. Go to the Registries page
...
.
...
Click
...
a registry ID.
2. On the Registry details page, click Gateways
...
and Add gateway to create a new gateway.
3. Enter a
...
gateway ID that
...
describes the gateway
...
and helps you identify it
...
(
...
this field can't be edited later).
...
4. For Gateway communication, select Allow or Block.
...
The latter allows you to block communication when needed, such as when a gateway or one or more devices bound to it are not functioning properly.
...
You’ll most likely want to allow communication when
...
creating the gateway. When a gateway is blocked, all devices bound to it are
...
blocked from communicating with
...
ClearBlade IoT Core.
5. Select the
...
public key format that matches
...
this gateway’s key pair
...
. Paste the certificate or key in the Public key value field. You can also set
...
the key’s expiration date
...
.
6. Select the authentication method to use for devices bound to the gateway.
7. Use the Key and Value fields to add optional gateway metadata, such as a serial number.
...
Under Stackdriver Logging, select an activity log level for the gateway. The gateway's log level overrides its registry's log level.
...
8. Click Submit to create the gateway or Update to save changes to an existing gateway.To edit

Edit an existing gateway

...

1. Go to the Registries page

2. Click the

gateway’s registry ID.
3. Click Registry details.
4. Click Gateways.
5. Click the gateway’s ID
...
you want to edit.
6. Click Edit at the top of the page.
To add a key to an existing gateway, click Add public key on the Device details page.

Configuring the gateway and getting state

With ClearBlade IoT Core, you can control a gateway by modifying its configuration, just as you would with any other device. See Configuring Devices to learn how to configure a gateway over the MQTT or HTTP bridge.

After a configuration has been applied to a gateway, the gateway can report its state to ClearBlade IoT Core. You can compare the gateway's state and its most recent configuration to make sure the gateway is doing what it's supposed to be doing.

Binding or unbinding a device

You can authenticate non-gateway devices to ClearBlade IoT Core by binding them to the gateway. Binding creates an association between the devices and the gateway that ClearBlade IoT Core checks to authenticate the devices.

Note: Binding is required when using the HTTP bridge.

Console -

Go to the Registries page in Google Cloud console.
Click the ID of the registry for the gateway.
Click Gateways, then click the gateway's ID.
On the Gateway details page, click Bound devices.
Click Bind device.
Select the devices you want to bind to the gateway, then click Bind.
To unbind a device, select the device in the Gateway details page and click Unbind device, then click Unbind again to confirm.

API -

Use the following methods to bind a device to or unbind a device from a gateway:

Registries BindDeviceToGateway method (projects.locations.registries.bindDeviceToGateway) to bind devices to gateways
Registries UnbindDeviceFromGateway method (projects.locations.registries.unbindDeviceFromGateway) to unbind devices from gateways

Listing all devices bound to a gateway

Console -

Go to the Registries page in Google Cloud console.
Click the ID of the registry for the gateway.
Click Gateways, then click the gateway's ID.
On the Gateway details page, click Bound devices.

API -

Use the Devices list method (projects.locations.registries.devices.list) and specify a gateway ID to list all devices bound to the gateway.

Listing all gateways in a registry

Console -

Go to the Registries page in Google Cloud console.
Click the ID of the registry for the gateway.
On the Registry details page, click Gateways to see a list of all gateways in that registry.

API -

Use the Device list method (projects.locations.registries.devices.list) to list all gateways in a registry.

Deleting devices bound to a gateway

To delete a device bound to a gateway, you first unbind the device from all gateways it's bound to, then delete the device from the registry.

Console -

Unbind the device from every gateway it's bound to.
In the Device details page, click Delete.
Enter the device ID to confirm and click Delete.

API -

After unbinding the device from all gateways it's bound to, use the Device delete method (projects.locations.registries.devices.delete) to delete the device.

Deleting a gateway

To delete a gateway, you first unbind its devices then delete the gateway from the registry.

Console -

Unbind all devices from the gateway.
Go back to the Gateway details page and click Delete.
Enter the gateway's name to confirm, then click Delete.

Deleting devices bound to a gateway

To delete a device bound to a gateway, you first unbind the device from all gateways it's bound to, then delete it from the registry.

Console

1. Unbind the device from every gateway it's bound to.

2. In the Device details page, click Delete.

After unbinding the device from all gateways it's bound to, use the device delete method to delete the device.

Deleting a gateway

To delete a gateway, you first unbind its devices and then delete the gateway from the registry.

Console

1. Unbind all devices from the gateway.

2. Go back to the Gateway details page and click Delete.

API

After unbinding all devices from the gateway, use the device delete method to delete the gateway, specifying the gateway’s ID you want to delete.
