How to configure a node for control model?

[Sash]

How to configure a node for control model. I have used light switch on/off template to implement a control mode but i i don't know how to make a control logic for client. Have to use only client at a time but if i run the code i'm getting error and it run both client and sever at same time. I have merge the client and server program for control model but i'm getting a error as NRF_INVALID_STATE which is in nrf_mesh_init function.Please help me and thanks in advance.

Which mesh sdk version are you currently using? Have you taken a look at the creating new models documentation? This documentation might also be helpful. What error are you currently receiving? As far as I know, we have not implemented a control model yet, but I have asked about this internally & will get back to you soon.

Thanks for your reply. I'm using mesh sdk 2.1.1. For control model i used light switch control example by merge client and server main.c i'm getting error as NRF_INVALID_STATE. I have problem to initialize mesh stack & softdevice for both client and server same time. only for first time i can use mesh stack and softdevice if use the same for server i get this error.

I have added the log which i get error:

Have you tried adjusting the app_ram_base like it says: "app_ram_base should be adjusted to 0x20002DA0"? You can do this by right-clicking your project -> Edit Options, changing to Common Configuration, going to the Linker tab & double clicking on Section Placement Macros. There, you can change the RAM_START value to 0x20002DA0.

I have tried but still i'm getting the same error. Can I use mesh init function 2 times as for client and server?
