nRF Thread Topology monitor 0.8.0-1 with cloud_coap example

[Reto]

Dear community,

I have your Thread example set up with 3 nRF52840 Preview Development Kit. nRF Thread Topology monitor 0.8.0-1 runs fine if I download CLI-example onto my boards. But Topology monitor does not run if I download the cloud_coap_client example.

I always get the error:

"Serial port COM3 has been successfully opened."

"Successfully verified Thread CLI device."

"Resetting and configuring Thread CLI device.."

"Error - No response from Thread CLI device."

But I can talk to the cloud_coap_client through serial port (get 'state', 'panid', etc.).

• Should the cloud_coap_client example also run with the Topology monitor? As I understand it should.
• Is this a bug? Or do I make a mistake?

Thank you for a quick answer or help. Reto

Hi Reto,

To use Thread Topology Monitor PC app, you should dedicate one Dev Kit with pure CLI example flashed. You should not use other examples which expose CLI interface in addition to their main functionalities. One of the reason is that Thread Topology Monitor calls some commands through CLI which are also called internally by applications (like cloud_coap_client), which in result causes errors. For more info about Thread Topology Monitor please refer here.

Best regards,

Krzysztof
