[Feature Request]: Test nodes network connection

[KomelT]

Hello, I am having an issue with one of my nodes connected via USB to a server with a network connection. Currently, I am unable to physically check this node. I think it would be a great feature to check with CLI if the node is connected to the Wifi / MQTT server.

I'm not really sure what you'd want to be tested here -- could you provide more details? I don't think that there's currently anything on the client API that would know if a network or MQTT connection is active or successful, so if you were thinking of it happening that way it might require a firmware change. If you're thinking of testing it by some other method, it might be possible (though depending on the details it might not make that much sense in this library/CLI). So let me know what you were thinking, if you could.
