With the IAM Role for IoT in place, the next step is to register the device as Thing in the AWS IoT Core.

1. You will first create an IoT policy which authorizes the device to perform actions within AWS IoT core. Goto the IoT Core Console, click on Policies menu under Secure in the left and then click on the Create a policy button.

   

2. On the next screen, enter policy name as dojodevicepolicy, enter “iot:*" for the Action, enter "*" for the Resource ARN, select Allow for the Effect and click on the Create button. You are creating a no restriction type policy for the workshop. However, in the production implementation, you might want to configure policies with restrictions for the actions and the resources.

   

3. The policy is ready. After creating the policy, you will now create a device as thing and attach the policy to it.

4. On the AWS IoT Core console, click on Things menu under Manage in the left and then click on the Register a thing button.

   

5. On the Creating AWS IoT things screen, click on the Create a single thing button.

6. On the Add your device to the thing registry screen, enter the device name as dojodevice1 and click on the Next button.

   

7. On the Add a certificate for your thing screen, click on the Create certificate button. It will create certificate files which the device uses for the authentication purpose. AWS IoT supports X.509 client certificates.

8. On the Certificate created screen, click on the Activate button to activate the certificate. Finally click on the Attach a policy button.

   

9. On the Add a policy for your thing screen, select dojodevicepolicy and click on the Register Thing button.

   

10. The device registration is complete. Let’s create a Lambda function which is called by IoT Core to pass the device messages for the processing.
