CSR µEnergy CSRmesh™ 1.3 Light Application – Application Note

1. Introduction

This document describes the CSRmesh™ Light on-chip application built using the CSR µEnergy® Software

Development Kit (SDK).

The application demonstrates the following use cases:

 Light Control: The Light application implements the handler for the CSRmesh messages related to the

Light Model, Power Model, Firmware Model, Stream Model and Attention Model.

 CSRmesh GATT Bridge: The application also implements the CSR custom Mesh Control Service. This

service allows a Bluetooth Smart enabled phone to send and receive CSRmesh messages to many

devices with the light application acting as a bridge.

The CSRmesh Light Application is provided as part of the CSRmesh release to demonstrate CSRmesh light control

use case.

The application uses the CSRmesh library which is provided as part of the CSRmesh release. See the CSRmesh

API Guide documentation for details.

The CSRmesh Light Application does not support bonding and is not compatible with previous releases of

CSRmesh.

CSR µEnergy CSRmesh™ 1.3 Light Application – Application Note

1.1. Application Overview

The CSRmesh Light Application uses the CSRmesh library API to communicate with other devices that are

associated within the same CSRmesh network. Additionally it supports a custom GATT profile to allow control of the

CSRmesh from a Bluetooth Smart enabled device.

1.1.1. Profiles Supported

The CSRmesh applications referred to in section 1 implement the following CSR custom profile to support the use

cases described.

1.1.1.1. CSRmesh Control Profile

The CSRmesh Control Profile defines the behaviour when:

 A network of devices such as lights and switches needs to be created.

 Controlling the device after a network has been created. For example, switching on/off, changing the

intensity or the colour of a light.

 Reading the status of a device in the network, for example on/off state, colour or intensity of a light

device.

The CSRmesh Control Profile defines the following two roles shown in Table 1.1.

Role Description

CSRmesh Bridge Device Receives commands from host and sends them over the CSRmesh network

to associated devices.

Receives responses from associated devices over the CSRmesh and

forwards them onto the host over a Bluetooth Smart connection.

CSRmesh Control Device The CSRmesh Control Device provides the interface to create a network of

devices and to control the associated devices. The control commands are

sent over a Bluetooth Smart connection to the CSRmesh devices.

Table 1.1: CSRmesh Control Profile Roles

The CSRmesh Bridge Device role is implemented on the CSRmesh Light Application. The CSRmesh Control Device

is implemented on a Bluetooth Smart enabled phone or tablet.

1.1.2. Application Topology

The CSRmesh Bridge uses the following topology shown in Table 1.2 and Table 1.3.

Role Responsibility

GATT Server Accepts incoming commands and requests from a client and sends responses, indications

and notifications to the client.

GAP Peripheral Accepts connection from remote device and acts as a slave in the connection.
