I am following this tutorial for connecting Raspberry Pi to AWS IoT using Node.js SDK and I have done all the other steps but I am lost in the authentication and certificate step:
pi@raspberrypi:~ $ aws iot describe-endpoint
You must specify a region. You can also configure your region by running "aws configure".
pi@raspberrypi:~ $ aws configure
AWS Access Key ID [None]:
AWS Secret Access Key [None]:
Default region name [None]:
Default output format [None]:
pi@raspberrypi:~ $ ls

When I browse to https://A34SXNTM6AT7XH.iot.us-west-2.amazonaws.com/things/MyNewThing/shadow or https://A34SXNTM6AT7XH.iot.us-west-2.amazonaws.com I see Missing Authentication Token message:
I am not sure how to get the last step working so I could see stuff in the URLs when I browse to them. Can someone help me figure which steps I am missing or is missing from the tutorial?
This fixed the problem:
- Browse to
https://console.aws.amazon.com/iam/home?region=us-west-2#security_credential
and then if you don’t have a key click on create new access key and
if you already have it save the information and enter it in front of
entries of
aws configurecommand and also for region select “us-west-2” is Oregon is selected in your dashboard. - After that you will be able to see the credential in the following:
The AWS credentials file – located at
~/.aws/credentialson Linux, OS X, or Unix
