NRF Connect SDK: Bluetooth mesh, How to bind an existed appkey to a local model?

[binhla]

Dears all, 

When a bluetooth mesh node is done provisioning and added an appkey, I want to bind that appkey to  local models. 

I could not find any API for that.

Can you help me.

Best regards.

Hi.

You can configure the node using the nRF Mesh application after the device has been provisioned.

Dears,

Thank you for your prompt response.

So, that mean there are no api for binding appkey to a local model?

Best regards.

How are you provisioning your device?

Configuration Client

The Configuration Client model is a foundation model defined by the Bluetooth mesh specification. It provides functionality for configuring most parameters of a mesh node, including encryption keys, model configuration and feature enabling.

bt_mesh_cfg_app_key_add()

I have implement the provisioner on an ESP32 SOC. I also use the nRF Mesh mobile app.

I think the Configuration Client is for the Provisioner, not for the Nodes. 

What I want is APIs that can be used by the Nodes themselves.

If the Configuration Client can be implemented on the Nodes and config locally, please imfrom me.

Best regarads.

Dears,

I just post this for any one that need.

struct bt_mesh_comp bm_comp = {
    .cid = CONFIG_BT_COMPANY_ID,
    .elem = bm_elements,
    .elem_count = ARRAY_SIZE(bm_elements),
};

/*****/
bt_mesh_init(&bm_prov, &bm_comp);

void app_bm_local_config(void) {
    for (int e_idx=0; e_idx < bm_comp.elem_count; ++e_idx) {
        struct bt_mesh_elem *element = bm_comp.elem + e_idx;
        for (int m_idx = 0; m_idx < element->model_count; ++m_idx) {
            struct bt_mesh_model *model = element->models + m_idx;
            if (model->id == BT_MESH_MODEL_ID_CFG_SRV || model->id == BT_MESH_MODEL_ID_CFG_CLI || 
                model->id == BT_MESH_MODEL_ID_HEALTH_SRV || model->id == BT_MESH_MODEL_ID_HEALTH_CLI) 
                continue;
            if (model->keys[0] == 0xFFFF) {
                model->keys[0] = 0; /*Appkey index is 0*/
            }
            for (int k_idx=0; k_idx < CONFIG_BT_MESH_MODEL_KEY_COUNT; k_idx++) LREP_RAW("%d ", model->keys[k_idx]);
            if (model->pub) {
                if (model->pub->addr == 0) {
                    model->pub->addr = 0xC000; /*Publish to group address 0xC000*/
                }
            }
        }
    }
}

It worked with me. But It cannot save the configuration so every time the SOC is restart, the app_bm_local_config() must be call

Best regards.
