Bluetooth Mesh Light Lightness Model has no controls

[parksj10]

I'm trying to implement an esp32 to control an LED, and use bluetooth-mesh to communicate with the device. I've tried going through the documentation/examples and have set up models that incorporated the following models:

Code: Select all

ESP_BLE_MESH_MODEL_CFG_SRV
ESP_BLE_MESH_MODEL_GEN_ONOFF_SRV
ESP_BLE_MESH_MODEL_GEN_ONOFF_SRV
ESP_BLE_MESH_MODEL_GEN_POWER_ONOFF_SRV
ESP_BLE_MESH_MODEL_GEN_POWER_ONOFF_SETUP_SRV
ESP_BLE_MESH_MODEL_GEN_LEVEL_SRV
ESP_BLE_MESH_MODEL_LIGHT_LIGHTNESS_SRV
ESP_BLE_MESH_MODEL_LIGHT_LIGHTNESS_SETUP_SRV

However, when I try to control the device, there are no options in the element/model containing the "Light Lightness", yet there are options in the Generic Level Server. See these screenshots:




Any suggestions? Here's the full example code:

Code: Select all

Indeed, so far the nRF Mesh App has not yet implemented the light lightness server control options. From the App (and from what I have seen so far) is that you can control the Generic OnOff Model, the Generic Level Model, the Scene model.

Your nodes is probably well configured with all the models correctly set into node composition, but you cannot control all these models from the app.
