Issue sending data from UART over mesh

[Arij]

Hi, 

I've been working on a project where I need to send data from UART over mesh, I managed to create custom model for sending string data over mesh, I did merge UART example with mesh SDK, I started with light switch demo from mesh SDK v2.0.1 and with nRF5 SDK v15, now I'm trying to get the data received on UART to send it over mesh, but I didn't do it correctly, the send_my_message function kept sending the same random data, Any idea on how to make that work, it would be greatly appreciated.

Here is a snippet of my code:
