Chapter 1. Introduction

1.1

OVERVIEW

This document contains the software command reference and advanced configuration

settings for Roving Networks Bluetooth

data

modules. The document is applicable to

all Bluetooth data modules modules (such as the RN41 and RN42), and USB dongles.

Commands and settings that are specific to a single product or product family are iden-

tified as such in the document.

You configure Roving Networks Bluetooth devices over the Bluetooth link or over the

module’s UART using a simple ASCII command language. Set commands configure

the module and get commands echo the current configuration. Configuration settings

modified with set commands do not take effect until the module has been rebooted,

even though the get command may show otherwise.

This document assumes that you have a working knowledge of Bluetooth operation

and communications. To configure the Roving Networks modules you need a Blue-

tooth-enabled PC (either built-in or using a USB Bluetooth dongle). You can only con-

figure one module at a time. Once configured, module settings are saved (independent

of power down) until they are explicitly changed or the factory defaults are restored.

NOTICE TO CUSTOMERS

The commands and applications described in this document apply to Roving Networks

Bluetooth

data modules,

e.g., RN41 and RN42. For Bluetooth audio module configuration

information (e.g., RN52), refer to the

Bluetooth Audio Module Command Reference User’s

Guide.

1.2

EVALUATION BOARDS & REFERENCE DESIGNS

Roving Networks provides a variety of boards, kits, and reference designs that you can

use for evaluation and prototyping.

The RN-41-EK and RN-42-EK evaluation boards are field-ready, Bluetooth SIG quali-

fied prototyping platforms for the RN41 and RN42 modules, respectively. The boards

have the flexibility to connect directly to PCs via a standard USB interface (via the FTDI

chipset) or to embedded processors through the TTL UART interface. The status LEDs,

dipswitches, and signal headers enable demonstrations and proofs of concept.

The Bluetooth HID reference design is implemented in the RN42HID-I/RM module. The

Bluetooth HID profile is typically used in applications such as keyboards, mice, and

game controllers. To demonstrate the basic capability of the Bluetooth HID profile, Rov-

ing Networks has developed a Bluetooth reference design implemented in the

RN42HID-I/RM module. The reference design operates in three modes:

•

Presenter mode—Used

for presentation software such as Microsoft Powerpoint

•

Music mode—Music

controller for products such as the iPod, iPhone, and iPad

•

Custom mode—You

can configure each button to send a sequence of up to 4

keys
