Create a Thing
Create a Thing first
Single Thing
- Create a AWS IoT Thing
- Thing Name
- Provide a Name to the Thing
- Copy thing name into THINGNAME
- Click Next
- Create Certificates
- Click on Create Certificate
- Download Certificates Download the following
- Contents for client_cert[] from XXXXXXXXXX.cert.pem

- Download the RSA 2048 bit key
Attached the Policy created from step above
Interact with AWs IoT Core
- look for HTTP end point and copt it into MQTT_HOST[]
- Copy thing name into THINGNAME (same name from step 3)
