[NRF MESH] Problem when creating NEW MODEL for proxy example

[William Nguyen]

Hi all, I'm working on creating new model for sending a byte from proxy client based on Generic On Off model. For working with light-switch proxy example, I used NRF Mesh Application(on Android) as a provisioner.
My new model was only working fine if GENERIC_BYTE_CLIENT_MODEL_ID defined the same as GENERIC_ONOFF_CLIENT_MODEL_ID(0x1001).
But when I change my model id to another variable(0x0005), a problem happened: After had provisioned successfully by the NRF Mesh Application, I clicked on CONFIGURATION and it was automatically closed the app, and after that I didn't see my model shows inside the Element collapsed. I thought It must have a name of my model like Unknown Model or something like that. 
How can I make this case work? I mean about Model ID on proxy example, do we have to use a defined model ID?

Hi,

I'm not sure why the nRF Mesh app is crashing, but have you followed this when creating a new model?

I've already followed it. It worked well. I was trying to send a byte(213 for instance) from client to server. It worked with no problem. But I don't know how to publish a message back to client from server. I mean when I wrote a byte_publish() using access_model_publish()  function based on  reply_status() function to send a byte back in server side. But I don't know how to show log to know the value send from server in debugging terminal on client side.
