How to acknowledge on a received opcode from respective server handler

[Ubaid_M]

Hi,

My BLE-Mesh client model sends an opcode to retrieve the server model state,
When server model receives the opcode, relevant handler gets triggered from where I need to acknowledge or send the server state to client.

Below handler I referred from nCS supplied "Chat" sample, wherein Chant presence is being sent.
But this is being sent to a device with an "addr", in my case I do not have an addr, as I am supposed to reply the state to the provisioning device, which is a mobile app.

int bt_mesh_chat_cli_presence_get(struct bt_mesh_chat_cli *chat,
				  uint16_t addr)
{
	struct bt_mesh_msg_ctx ctx = {
		.addr = addr,
		.app_idx = chat->model->keys[0],
		.send_ttl = BT_MESH_TTL_DEFAULT,
		.send_rel = true,
	};

	BT_MESH_MODEL_BUF_DEFINE(buf, BT_MESH_CHAT_CLI_OP_PRESENCE_GET,
				 BT_MESH_CHAT_CLI_MSG_LEN_PRESENCE_GET);
	bt_mesh_model_msg_init(&buf, BT_MESH_CHAT_CLI_OP_PRESENCE_GET);

	return bt_mesh_model_send(chat->model, &ctx, &buf, NULL, NULL);
}

Please suggest how I can reply the state to mobile app and which API I can use..?

Thanks,

Hi,

What do you mean you you don't have an address?

I am supposed to reply the state to the provisioning device, which is a mobile app.

What mobile app are you referring to here? Are you using nRF Mesh?

Since you are using a phone to provision, you can always set an address to the provisioner in the provisioner settings. An address is needed to send config messages or other messages than provisioning messages.
