1. Create Policy

2. Register a thing

3. Create the certification and connect policy that was made before

4. Test the connection to IoT Core

1. Create Policy

1) In the left navigation pane, choose secure, and then choose Policies. Click create a policy button

2) Enter restriction infomation that mean allowed all clients to connect to AWS IOT.

 - In the Action field, enter "iot:*". The type of actions that can be perfomed by a resource.

3. Create the certification and connect policy that was made before

1) Create the certification automatically, and then download connection kit.

2) Connect a policy to the certification

 - That can help allow all clients to connect to AWS IoT and publich messages to the specified topic.

 

4. Test the connection to IoT Core

* Note

 - Run Test Code. "-t" option is topic

python aws-iot-device-sdk-python\samples\basicPubSub\basicPubSub.py -e 

xxxxxxxxxxxxx-ats.iot.ap-northeast-2.amazonaws.com -r root-CA.crt -c eccTest03.cert.pem -

eccTest03.private.key -t ecc/test/python

 - Modify this code in "basicPubSub.py"
