send data from client to specific server via unicast address

[michel_93]

Hi Guys,

We are currently working on a mesh sensor network. I have already developed a vendor sensor model (client and server). The client will also work as a gateway and will run on a nRF52840 DK. The Provisioner is on a separate DK just like in the Light Switch Example. The sonsors are a costum hardware with an nRF52840 on it.

The sensor send data on regular bases to the client via the mesh and the client then send it via UART to a computer.

During the provisioning process the nodes are picked randomly to add them to the network. Now the problem is that I have to know which device has received which unicast address.

I now want to send an On/Off message from the client to a unicast address and set an LED to identify which node it is. For that I have to change the publication address of the client locally. So is this possible without the provisioner? I have read that there is the following function available to change the publication address of a node: access_model_publish_address_set()

I found out that this function is in the access_config. h file decelerated but I haven't found a access_config.c file.

So which files do I have to include to use this functions?

Is there another way to change the publication address of a node locally?

Best regards,

Michel

You change the publication address like this: 

uint32_t status = NRF_SUCCESS;

  dsm_handle_t publish_address_handle = DSM_HANDLE_INVALID;
  nrf_mesh_address_t publish_address_stored;

  if (access_model_publish_address_get(m_clients[0].model_handle, &publish_address_handle) != NRF_SUCCESS) {

    status = dsm_address_publish_add(destination_address, &publish_address_handle);

  } else {

    if (dsm_address_get(publish_address_handle, &publish_address_stored) == NRF_SUCCESS) {

      if ((publish_address_stored.type == NRF_MESH_ADDRESS_TYPE_VIRTUAL) ||
          (publish_address_stored.type != NRF_MESH_ADDRESS_TYPE_VIRTUAL &&
              publish_address_stored.value != destination_address)) {
        /* This should never assert */
        NRF_MESH_ASSERT(dsm_address_publish_remove(publish_address_handle) == NRF_SUCCESS);
        status = dsm_address_publish_add(destination_address, &publish_address_handle);
      } else {
        /* Use the retrieved publish_address_handle */
      }
    } else {

      status = dsm_address_publish_add(destination_address, &publish_address_handle);
    }
  }

  switch (status) {
  case NRF_ERROR_NO_MEM:
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "NRF_ERROR_NO_MEM\n");
    //            status_error_pub_send(handle, p_message, sig_model, ACCESS_STATUS_INSUFFICIENT_RESOURCES);
    return;

  case NRF_SUCCESS:
    break;

  default:
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "ACCESS_STATUS_UNSPECIFIED_ERROR\n");
    //            status_error_pub_send(handle, p_message, sig_model, ACCESS_STATUS_UNSPECIFIED_ERROR);
    return;
  }

  NRF_MESH_ASSERT(access_model_publish_address_set(m_clients[0].model_handle, publish_address_handle) == NRF_SUCCESS);

destination_address is unicast address you want to send on/off command. You can figure out which header file you must include by searching the function on all solution.

Thank you very much the solution works
