[sivaguru]

i am trying to develop custom board with 1 client(pca10056) and 20 server(pca10059) to get sensor data ,

I tried https://devzone.nordicsemi.com/f/nordic-q-a/39896/modifying-the-light-switch-example-mesh-sdk-2-2-0  to get data transfer in the mesh. I included uart instances.     

How to send message from client to single server node ??                                                                                           

uint32_t generic_onoff_client_set	(	generic_onoff_client_t * 	p_client,
const generic_onoff_set_params_t * 	p_params,
const model_transition_t * 	p_transition 
)	

   what are the things to be edited in above function ???
