USER’S GUIDE
Chapter 1. Introduction

®
Thank you for purchasing the Microchip Technology PIC32 Bluetooth Starter Kit (P/N: DM320018). This starter kit provides a low-cost solution for developing Bluetooth Serial Port Profile (SPP) applications.
1.1 KIT CONTENTS

The starter kit ships with demonstration code that enables SPP full-duplex data trans-mission with many connected Bluetooth-enabled smart devices. The starter kit supplies on-board circuitry for full debug and programming capabilities and includes an inte-grated Bluetooth HCI module. Optionally, the starter kit board may be coupled with an expansion daughter board through its expansion header interface.

The PIC32 Bluetooth Starter Kit contains the following items:

• PIC32 Bluetooth Starter Kit development board, which includes:

- An integrated HCI-based Bluetooth radio

- USB host and device connectors

- High output multi-color LED

- Accelerometer and temperature sensor.

• USB Type-A to B-mini cable for power and debug of the development board

Note: The starter kit is preprogrammed with Bluetooth SPP full-duplex data transmission demonstration software and more demonstrations are planned in the near future. The demonstration applications are available for download with MPLAB® Harmony v0.80.02 or later. Please refer to the MPLAB Harmony documentation, which is available from http://microchip.com/harmony/ for more information on these demonstrations. An Android application for handsets is also available in this version of MPLAB Harmony to support the SPP data demonstration.

Note: If you are missing any part of a kit, contact a Microchip sales office for assis-tance. A list of Microchip offices for sales and service is provided on the last page of this document.

USER’S GUIDE
Chapter 2. Hardware

This chapter describes the hardware features of the PIC32 Bluetooth Starter Kit

2.1 HARDWARE FEATURES

The following key features of the starter kit are presented in the order provided in 1.2 “PIC32 Bluetooth Starter Kit Functionality and Features”. Refer to Figure 1-1 and Figure 1-2 for their locations on the development board.

2.1.1 Bluetooth ModuleThe FLC-BTM805 is a dual-mode Bluetooth HCI module that allows original equipment manufacturers to add Bluetooth wireless capability to their products. The module supports BT2.1 and later with an HCI interface, which makes it simple to design into fully certified embedded Bluetooth solutions. The module supports Bluetooth Enhanced Data Rate (EDR) and delivers up to a 3 Mbps data rate. In addition, the module supports Class 1 transmission and multiple device connection.

2.1.2 Processor SupportThe development board in the starter kit is designed with a permanently mounted (i.e., soldered) PIC32MX270F256D microcontroller. Support for this microcontroller is available using the Microchip MPLAB® X IDE v2.10 and later, and with the MPLAB XC32 C/C++ Compiler v1.32 or later.

2.1.3 Powering the Starter KitUse one of the following methods to provide power to the starter kit:

• Connect USB bus power to the USB debug connector, J7

• Apply VBUS (+5V) power to the micro-B USB connector

• Connect an external application board with a regulated DC power supply that provides +5V to the J8 header (not populated)

2.1.4 USB Connectivity

2.1.4.1 HOST MODE

Connect the device to the Type-A connector, J1, which is located on the top of the starter kit development board.

2.1.4.2 DEVICE MODE

Connect the starter kit to the Host using a cable to port J2, which is located on the bottom of the starter kit development board.

2.1.4.3 DEBUGGING MODE

The starter kit includes a PIC24FJ256GB106 USB microcontroller that provides debug-ger connectivity over USB. The PIC24FJ256GB106 is hard-wired to the PIC32 device to provide protocol translation through the I/O pins of the PIC24FJ256GB106 to the ICSP™ pins of the PIC32 device.

Connect the starter kit to port J7, which is located on the top side of the starter kit development board.



2.1.5 Switches

Switches, SW1-SW6, are available on the development board of the starter kit. SW6 is connected to the reset pin (RB5) of the board. When Idle, the switches are pulled high (+3.3V), and they are grounded when pressed.

2.1.6 Other Features

The starter kit is integrated with a temperature sensor, the Cree high output multi-color LED with PWM, a 3D- accelerometer, and an authentication connector. These features are used for application development purposes.
