Hi,
I have followed the Chat Sample Walkthough, Vendor Model Development Overview and other examples from different vendors using zephyr, but I'm getting stuck at the following point:
In the model_handler at bt_mesh_elem list I add my vendor model with callbacks:
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_VND_CB(BT_MESH_VIBE_SERVER_VENDOR_COMPANY_ID, \
BT_MESH_VIBE_SERVER_VENDOR_MODEL_ID, \
vibe_server_opcode_list, \
NULL, \
NULL, \
&vibe_server_cb)
)),
};
I have added init, start and reset functions in my vendor model with log outputs, but those never get called. I trimmed down the chat sample a lot and had to create the server vendor model (since the chat model doesn't really show a server approach), but I think I may have done something incorrectly or missed a step.

Is my approach to the custom vendor model doable or should I follow more strictly the chat sample with it's chat_cli struct and function pointers?
