Problem Description

I am currently trying to use the BLE Mesh API to create a game, and I will have until 16 devices to connect, each device has one button and one RGB led. I want the devices to start as node(unprovisioned) and if push the button of one, it will become a provisioner and provision the 15 devices left. So the problems is :

When I want to use both mode in the same program, a node can start properly, but not a provisioner. And I still don't know how to do that after some days of research.

The program is still running after the error, but only reproduce the watchdog reset

Steps to repropduce

Copy the ble_mesh_provisioner example, in $IDF_PATH\examples\bluetooth\esp_ble_mesh
run "make menuconfig" -> "Component config" -> "ESP BLE Mesh Support" -> Check "Support for BLE Mesh Node"
run "make -j4 flash monitor"
wait

Question

How can I turn a node(unprovisioned) into a provisioner after using esp_ble_mesh_init once ? Do I have to restart the ESP ?

Hi Quiscale， Note: bt_mesh_proxy_init, Device UUID is not initialized

 The cause of the error is that the device's uuid is not initialized.

 You need to initialize the uuid variable in `esp_ble_mesh_prov_t` .

 You can refer to the `ble_mesh_node` demo.

Hi WCCWCC,

Yes I found my error not a long time ago, I don't know why but to solve my problem I did as you said it : That was my code :

static esp_ble_mesh_prov_t mesh_provision_prov = {
        .prov_uuid           = MESH_uuid,
        .prov_unicast_addr   = 0x0001,
        .prov_start_address  = 0x0005,
        .prov_attention      = 0x00,
        .prov_algorithm      = 0x00,
        .prov_pub_key_oob    = 0x00,
        .prov_static_oob_val = NULL,
        .prov_static_oob_len = 0x00,
        .flags               = 0x00,
        .iv_index            = 0x00,
};

And now It looks like :

static esp_ble_mesh_prov_t mesh_provision_prov = {
        .uuid = MESH_uuid,
        .output_size = 0,
        .output_actions = 0,

        .prov_uuid           = MESH_uuid,
        .prov_unicast_addr   = 0x0001,
        .prov_start_address  = 0x0005,
        .prov_attention      = 0x00,
        .prov_algorithm      = 0x00,
        .prov_pub_key_oob    = 0x00,
        .prov_static_oob_val = NULL,
        .prov_static_oob_len = 0x00,
        .flags               = 0x00,
        .iv_index            = 0x00,
};

And it works, so I need to register twice the uuid
