After you create a gateway, you can't change it to a non-gateway device. Ensure you've created a registry and a device key pair before completing the steps in this sectionbelow.

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.

See Creating or editing a device to learn how to create the devices you'll use with the gateway.
...
With ClearBlade IoT Core, you can control a gateway by modifying its configuration, like any other device. See Configuring Devicesdevices to learn how to configure a gateway over the MQTT or HTTP bridge.
...
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
1. Go to the Registries page.
2. Click the gateway’s registry ID.
3. Click Gateways, then click the gateway's ID.
4. On the Gateway details page, click Bound devices.
5. Click Bind device.
6. Select the devices you want to bind to the gateway, then click Bind.
7. To unbind a device, select the device in the Gateway details page, and click Unbind device and Unbind to confirm.
API
Use the following these methods to bind a device to or unbind a device from a gateway:
...
| Code Block |
|---|
if (bBindUnBindDevice)
{
logger.LogInformation("Get configuration of a device");
// While running this sample, it is assumed that, device with name
// "Sample-New-Device" exists and Gateway with name "TestGateway" exists

Listing all devices bound to a gateway
Console
1. Go to the Registries page.
...
Click the gateway’s registry ID.
2. Click Gateways, then click the gateway's ID.
3. On the Gateway details page, click Bound devices.
