Select the policy version and click on the "Edit versions" button

Update "Resource" in the JSON file and save it as a new version, then go back to the Policies page and select the new version as active.

5. Define the destination in the destinations.syrus.conf file

define destination awsmqtt json aws://a2b6cghq3lfdh2-ats.iot.us-east-1.amazonaws.com:8883 
client_id="syrus-867698041094437" publish="zenzando/events" subscribe="zenzando/configuration" 
commands_pub="zenzando/commands_pub" commands_sub="zenzando/commands_sub" 
key_name="Syrus_demo.private.key" cert_name="Syrus_demo.cert.pem" ca_name="AmazonRootCA1.pem"

Note: you need to update your destinations.syrus.conf with your own values.

5. Upload the necessary files on Syrus 4G

Note: If you need to create an instance in the Syrus 4 Management Tool, please go to Application Manager.

In the Syrus 4 Management Tool upload:

• {name_device_aws}.cert.pem and {name_device_aws}.private.key included in the connection kit from step 2.
• {AmazonRootCA1}.pem downloaded in step 3.
• configurations.syrus.confand destinations.syrus.conf configuration files for syrus.

6. Test the connection
