Thread topology monitor does not work on Ubuntu 18.

[jarekb123]

I set the Thread network with 2 Dev Kits. I tested it using CLI directly. The network works.

But I can't observe topology on the monitor tool.

Reproduce path:

1. Follow the steps from here: https://www.nordicsemi.com/DocLib/Content/SDK_Doc/Thread_SDK/v2-0-0/thread_topology_monitor
2. Click "Start Scan" on the Topology monitor.
3. Check the state by running "state" command in Thread CLI.

After this steps the state is changed to "disabled" and the monitor says that "Error - No response from Thread CLI device.".

I run Ubuntu 18.10.

Hi,

Please make sure that you check the "Perform factory reset" checkbox in the application:

I initially got the same error with similar setup to you, but checking this box fixed the issue.

Best regards,
Jørgen
