duplicate designator is not allowed C/C++ (2906)

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

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

Or initialize each member individually in model_handler_init

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.
