No steps/code for attaching policy to device cert #7

@coderbyheart What is the expected behavior for the simulated device? I'm seeing constant disconnect -> reconnect -> connected after the shadow is set:

I don't see where in the code you are attaching the policy to the device cert.

For troubleshooting purposes I created a dfu_simulator policy and then ran aws iot attach-policy --policy-name dfu_simulator --target arn:aws:iot:us-east-1:680502709288:cert/49fbb87fe6a087e48110f1b5c7083063e80d4914828e20cdbaa0e230d47cb515 to attach it to the cert for my device and that resolved the issue:

  }
}

Not sure how you want to handle this in the project.

Make sure the device you use has sufficient permissions to interact with the AWS IoT Jobs topics. This is not set up for you by the simulator.
