2.3.2 AWS Certificates and Configuration From stackArmor
To connect the IoT Gateway to the AWS IoT service, the gateway needs authentication certificates
provisioned by AWS. For these certificates, as well as a unique AWS URL, see the stackArmor web
page[8]. Return to this guide once obtaining the following:
• certificate.pem.crt
• private.pem.key
• public.pem.key
• root-CA.crt
• a URL to the AWS host that should be used
Use SCP to copy the four files into the {demo software directory}/prebuilt/iot-gateway/cloudAdapter/certs/
directory on the BeagleBone Black’s file system.
