The GA edgeHub does not return connectionState

[shizn]

The EdgeHub module does not return connectionState, in VS Code, we cannot visualize the module states without it.

Expected Behavior

By returning the connectionState, customer can visualize edgeHub module states during development.

Current Behavior

Always blue because no connectionState

Steps to Reproduce

1. Expand an active IoT Edge device in VS Code and look into the module list.

Hello @shizn,

Thank you for the report, Xin.

This is in the reported properties of the $edgeHub module twin, correct? I will mark this as a bug and put it in our back log.

Hi Xin,

So this behavior is because IoTHub uses the D2C telemetry link status to determine if the device is connected or now. But since the EdgeHub doesn't send any telemetry, it never opens that link. So the module shows up as disconnected.

Either of those will be hard to fix at this point. Can you use the RuntimeStatus of the module in the EdgeAgent reported properties instead? That should give you an accurate status of which modules are running and which are not.

Thanks for the information, Varun. We will take a look and use RuntimeStatus to update the status in VS Code.
