How to inmplement Client model on a phone?

[UdjinPr]

Hi!

I met some issue ). 

I use nrf mesh app on my phone and change it for my goals. I would like to get messages from nodes to phone via mesh. I read some posts that it is possible to implement client model on a phone and subscribe to server of nodes to get messages. I tried to figure out how .... And may i should configure node on my phone and then add models?  May be there is examples ? Or you can explain in a nutshell.

Thank you for your time.

Hi,

What kind of changes have you made to the app? 

When you say "subscribe to server of nodes to get messages", do you mean status messages from the server?

In our current nRF Mesh app, there is a local client model on the phone. Have a look at this thread on how you can receive status messages from server.

Are you using the latest version of the app?
