Hi,

There is code for vendor model element creation in nCS provided Chat client sample, as in below:

static struct bt_mesh_elem elements[] = {
	BT_MESH_ELEM(
		1,
		BT_MESH_MODEL_LIST(
			BT_MESH_MODEL_CFG_SRV,
			BT_MESH_MODEL_HEALTH_SRV(&health_srv, &health_pub)),
		BT_MESH_MODEL_LIST(BT_MESH_MODEL_CHAT_CLI(&chat))),
};

This works fine in "model_handler.c",

But when I import the same code to the file "model_handler.cpp", I get a build error saying 

On : 

BT_MESH_ELEM(

I cannot avoid C++ here, kindly suggest for me to solve this.
Thanks,
Ubaid

    Hi,

    Try initializing each member of bt_mesh_elem without using the BT_MESH_* helper macros. 

    I tried doing this As in below:

     static bt_mesh_elem elementsx = {.loc=1, .model_count=2, .vnd_model_count=1,
 .models = BT_MESH_MODEL_LIST(BT_MESH_MODEL_CFG_SRV,BT_MESH_MODEL_HEALTH_SRV(&health_srv, &health_pub)), 
 .vnd_models = BT_MESH_MODEL_LIST(BT_MESH_MODEL_VND_CB(BT_MESH_CORPORATION_ID, BT_MESH_MODEL_CUSTOM_SRV,
 			_bt_mesh_custom_srv_op, &(cstm_srv)->pub, BT_MESH_MODEL_USER_DATA(bt_mesh_custom_srv, cstm_srv),
 			&_bt_mesh_custom_srv_cb))
 };

    This is giving an error with the line: 

    .vnd_models = BT_MESH_MODEL_LIST(..........
    Here it says, unable to use -> operator or  *cstm_srv on BT_MESH_MODEL_USER_DATA.
