Light CTL Client

The Color-Tunable Light (CTL) Client model remotely controls the state of the Light CTL Server model, and the Light CTL Temperature Server model.

Unlike the server models, the Light CTL Client only creates a single model instance in the mesh composition data. The Light CTL Client can send messages to the Light CTL Server, the Light CTL Setup Server and the Light CTL Temperature Server, as long as it has the right application keys.

Note

By specification, the Light CTL Temperature Server must be located in another element than the Light CTL Server models. The user must ensure that the publish parameters of the client instance point to the correct element address when using the function calls in the client API.

Extended models

None.

Persistent storage

None.

Shell commands

The Bluetooth mesh shell subsystem provides a set of commands to interact with the Light CTL Client model instantiated on a device.

To make these commands available, enable the following Kconfig options:

mesh models ctl instance get-all

Print all instances of the Light CTL Client model on the device.

mesh models ctl instance set <elem_idx>

Select the Light CTL Client model instantiated on the specified element ID. This instance will be used in message sending. If no model instance is selected, the first model instance found on the device will be used by default.
