How do I connect to the provisioned proxy node via smartphone(nRF connect for mobile)?

[Yoshihiro Goto]

I am developing BLE Mesh product with `nRF connect SDK`.

I understand most of sample project has a function of proxy node. But I don't know how to connect a provisioned node via proxy. A provisioned node doesn't advertise while connecting mesh network, right? Needless to say, I can connect to a provisioned node which is not connected to the mesh network because it is (mesh) advertising. Also needless to say, Provisioned nodes which connected by `nRF connect for mobile` cannot return to the mesh network.

I'm not sure if this is the correct procedure, when I launch `nRF connect for mobile` on my provisioned smartphone, it starts up connected to the node.
But if I want to use my own application, I can't use this method, right? How can I connect to a provisioned and connected node?

Ahh... I just understood and this post is misunderstood.

`nRF Mesh App` also uses proxy connection...right?

Hi Yoshihiro, 
Yes, correct. Right after provisioning the nRF Mesh app will automatically connect to the fresh provisioned node as a proxy node. The configuration steps is done via proxy channel, not provisioning channel. 

When you click Connect in nRF Mesh app, the app will try to scan and list the Proxy node around that you can connect. 

Since the node can only handle one connection at time it could be the reason why you couldn't see the node when it's already connected to nRF Connect app for example.
