The light switch client implements a Generic OnOff client. Together with light switch server and Bluetooth mesh provisioner, it is part of the light switch example network demonstration, in which it has a provisionee role.

The light switch client has four buttons to control the state of LED 1 on servers. It instantiates two instances of Generic OnOff Client model. It can either be provisioned and configured by the provisioner device or by a GATT-based provisioner. The provisioner configures this client model instances to communicate with servers.

Source code

You can find the source code of the light switch client in the following folder: <InstallFolder>/examples/light_switch/client

To run the light switch client example, see Light switch example.

Use of Bluetooth mesh APIs

The client uses the following set of APIs:

The client application is implemented in a similar way as that of the server (see examples/light_switch/client/src/main.c). Additionally, it has the following functionalities:

Handle button presses and call Generic OnOff client APIs to send Bluetooth mesh messages to the desired nodes or a group of nodes.
Handle model callbacks and print corresponding messages in RTT log.

The following figure shows the calling sequence of key Bluetooth mesh stack APIs used by the light switch client.
