SPP CONNECTION WITH A STANDARD PC

Quick Start Guide v1.4

INTRODUCTION

The Laird BT900 is a dual mode Bluetooth v4.0 module. This Quick Start Guide illustrates how to make Serial

Port Profile (SPP) connections with a standard Bluetooth-enabled PC using classic Bluetooth.

The BT900 series utilises Laird’s robust, field proven

smart

BASIC programming language, specifically designed

for resource constrained environments, to control and configure the module.

REQUIREMENTS

 DVK-BT900-Sx loaded with v9.1.2.0 or later firmware

- Firmware folder including X-Compiler (found in the Software

Downloads tab of the BT900 page)

 A PC with built-in Bluetooth OR Laird BT820 USB Bluetooth adapter

 Windows 7 or later



smart

BASIC sample applications from GitHub

 Laird UWTerminal serial program:

- Laird UW Terminal v7.0.0 (found in the Software Downloads tab of

the BT900 page)

The development board includes a USB port to provide power as well as serial communication to the BT900

via the on-board FTDI USB chip. This allows a user to quickly get started and load

smart

BASIC applications

into the BT900 using our terminal emulator program, UWTerminal.

SETUP PREPARATION

To prepare your setup, follow these steps:

Plug the BT900 development board into a USB port on the Windows PC. Windows should install the

driver automatically for the FTDI USB chip. If this fails, the driver is also available from the FTDI website.

Locate the COM port in Windows Device Manager. The COM port number varies for different

computers (Figure 2).

Download the

smart

Basic sample applications zip file from GitHub and unzip it to a folder on your PC

(such as C:\Laird\BT900). – The best practice is to maintain the same file hierarchy as is present in the

original zip file, as most of the sample applications rely on the included lib folder.

Download the X-Compiler and UWTerminal from the software downloads tab of the BT900 webpage.

Place the X-Compiler and UWTerminal in the same

smart

BASIC sample application folder.
