INTRODUCTION

Technologies that allow both wireless and wired

systems to communicate with other devices of the

same ability are referred to as Machine-to-Machine

(M2M). M2M uses a device to capture an event, which

is then relayed through a network to an application that

translates the event into meaningful information. A

common application of M2M is fleet management,

where vehicle tracking is wirelessly transmitted to a

central monitoring office over cellular networks.

There are many popular M2M applications, one of

which is a utility meter. One of the major benefits of a

M2M-based utility meter over a traditional one, is

immediate operational efficiency from reading and

programming meters remotely, which eliminates the

need to physically visit the meter.

Another application becoming more popular with M2M

technology is in-car GPS navigation. With this

technology, consumers now have a complete GPS

navigation system in their vehicles. This technology

can be used to track a driver’s current location, or

provide a map for directions. Also, the consumer can

make an emergency call from the same device that is

doing the tracking. Businesses can use this technology

for parking lots to know how long a vehicle has been

parked and to charge it accordingly.

The Microchip M2M PICtail™ Plus Daughter Board

(referred to as the M2M Board) developed by u-blox

AG, was designed to connect directly to the PICtail™

interface of the Multimedia Expansion Board (MEB),

but can also be used with any PIC32 microcontroller.

This application note describes a reference design that

enables the implementation of GSM/GPRS/GPS

connectivity using a PIC32 microcontroller (MCU), the

M2M Board, and the MEB.

Feature Overview

The M2M PICtail Plus Daughter Board contains many

features, including GSM, GPRS, and GPS.

• Global System for Mobile Communication (GSM)

• General Packet Radio Service (GPRS)

• Global Positioning System (GPS)

Functionality

The main functionality of the M2M Board is

accomplished using two communications modules from

u-blox A, which is a company that specializes in GSM/

GPS ICs. For more information, visit www.u-blox.com.

The M2M Board was designed to connect to

Microchip’s MEB. The MEB uses Microchip’s PIC32

starter kit collection as the primary controller source.

This suite makes it easy to start and implement

embedded controller projects due to its:

• Built-in debugger

• USB power source

• On-board header for easy attachment to PCBs

• PIC32 device with high-speed performance and

GSM is a popular world-wide standard for mobile

telephone systems. GSM includes technologies in

both signaling and speech channels, which are

digital; therefore, GSM is considered a Second

Generation (i.e., 2G) mobile phone system. This

facilitates the wide-spread implementation of data

communication applications into the system. GSM

also implements a Short Message Service (SMS),

called text messaging.

GPRS is a service on 2G and 3G cellular

communication systems (GSM). GPRS provides

data rates of 56-114 kbps, which provides users

with the capability to connect to the Internet.

GPS is a space-based navigation system that pro-

vides reliable location and time information in all

weather conditions and at all times, and anywhere

on or near the Earth when and where there is an

unobstructed line of sight to four or more GPS sat-

ellites. It is freely accessible by anyone with a GPS

receiver.
