BLE Mesh SDK - Publish to unicast address

Question

Hi, 
 
 how can I publish a message to unicast address from a generic on/off client with mesh sdk? 
 How can I set the address? 
 
 Jost to be more precise, the function: 
 access_model_reliable_publish(const access_reliable_t * p_reliable) 
 only works if the client model publishes on a unicast address: 
 if (pub_addr.type == NRF_MESH_ADDRESS_TYPE_UNICAST) { add_reliable_message(index, p_reliable); } 
 return NRF_SUCCESS; 
 
 What if the model publishes on group address? 
 We need to implement a gateway. How can we address singles nodes in the mesh net? 
 
 Thank you 
 Lucio

Hi Lucio, 
 Yes, you can have a the server on the gateway, if that node also act as a normal node. The client on the gateway can send packet to the server on the same node (but we will not broadcast the packet but route it internally ) 
 It's up to you to decide if you want to delete the address in DSM database. You don't have to follow what we have in the config_server.c . There is only one rule ab that, you can have only one publish address at a time. 
 I don't think you should call access_flash_config_store() this everytime if you switch server address all the time. There is some good read about flash usage in mesh here .
