asset_tracker_v2 configured to work with AWS works with SDK 1.6.0, gets disconnected right after connect when built under 1.7.0

JVantol

This is a pretty top level description of the problem. I've not dug very deep, but what I've observed is that when deployed against an AWS instance set up per the instructions at:

https://nordicsemiconductor.github.io/asset-tracker-cloud-docs/v1.6.x/docs/aws/GettingStarted/Index.html

The device is booted shortly after connecting and subscribing to topics.

With a 1.6.0 build, it works as expected.

It looks to me like the instructions for AWS have not been updated for the 1.7.0 SDK. Is this the case, and if so, are updated instructions forthcoming?

    The device is booted shortly after connecting and subscribing to topics.

    Could you provide the serial output from the application when the device reboots?

    Sorry, my terminology was unclear. It doesn't actually reboot, it is simply disconnected, and then retries later.

    Here's a log showing an boot, and then several cycles of connect/subscribe/disconnect.

    Thanks for the log. Could you take a modem trace during this event, so we can see more of the communication between the device and the MQTT broker? I suspect the host might be sending the disconnect and a modem trace might tell us why.
