server and client model in same element index

[bivay]

Can a server and a client of dimming example, have same element instead of different element ID.

I got worked for server and client model in single node, but they are in different element index.

When I combined in single element index, they worked, but I can't use unicast address to send data, I can only use Group address for it.

So, How can I use unicast address to send data from client to server and get data from server to client in response.

Thank You

Hi,

Which Mesh SDK are you using? I think your issue is related to this.

[bivay]

Mesh SDK: 3.2.0

I also tried to use two element one for server with health and config server.

and another for client.

and used this function:

static uint32_t set_model_publish_address(uint16_t publish_address, access_model_handle_t model_handle) {
  if (!m_device_provisioned) return;
  if(get_model_publish_address(model_handle)==publish_address) return;
  uint32_t status = NRF_SUCCESS;
  //publish_address=0xc000;
  dsm_handle_t publish_address_handle = DSM_HANDLE_INVALID;
  access_model_publish_address_get(model_handle, &publish_address_handle);
  NRF_MESH_ASSERT(dsm_address_publish_remove(publish_address_handle) == NRF_SUCCESS);
  status = dsm_address_publish_add(publish_address, &publish_address_handle);
  if (status != NRF_SUCCESS) {
    return status;
  } else {
    return access_model_publish_address_set(model_handle, publish_address_handle);
  }
}

when I use group address : 0xC000 and other this function works,

but when I use unicast address it didn't work

As of now the only workaround is to have client and server model in seperate elements. But this only apply if the responses sent by the server model is segmented messages, if not client and server model can be on the same element. We are looking into the issue and try to fix this as soon as possible. 

I'm a little bit confused, you said "I got worked for server and client model in single node, but they are in different element index." but now it doesn't work?

As you said when client and server is in different element, I can use above function to communicate.

Thank you for segmented message idea, I think I should try unsegmented method.

As in code message length for unsegmented message is 11 byte. I am right?

Yes, that is correct :)
