Help with Shadow updates to AWS

[James Solderitsch]

Following the advice here:
mqtt

I have the certificate, policy and end point defined I believe correctly.

I did the setup step and copied the certificate and private key files to the Omega2+.

I run:
mosquitto_pub -t $aws/things/Omega-27BF/shadow/update -m '{"state": {"desired": {"temperature": 1 }}}' -q 1

But the shadow properties do not get updated.

There is no error. If I add the -s option to the mosquitto_pub command I see:

Client mosqpub|30677-Omega-1F9 sending CONNECT
Client mosqpub|30677-Omega-1F9 received CONNACK (0)
Client mosqpub|30677-Omega-1F9 sending PUBLISH (d0, q1, r0, m1, '$aws/things/Omega-1F93/shadow/update', ... (43 bytes))
Client mosqpub|30677-Omega-1F9 received PUBACK (Mid: 1)
Client mosqpub|30677-Omega-1F9 sending DISCONNECT

Do I need to start over because I have updated the firmware on the Omega 2+.?

I am using certificate and policy files from Feb. 2018 when this guide worked for me.

Suggestions appreciated.
