2. CHAPTER 2 - PRODUCT

OVERVIEW

2.1 INTRODUCTION

G24 is a GSM/GPRS/EDGE OEM module. It is similar to a condensed cellular phone core, which can be integrated into a
communication system to enable the transfer of voice or data information over a cellular network. For a detailed description of
the G24 cellular engine refer to reference

This OEM module which once was controlled by an external CPU is now enhanced to be controlled by the customer’s java
MIDlet applications running on G24's CPU. This new module name is OEM KJAVA.

The main Java differences between a mobile handset and G24 KJAVA engines are shown in Table 1:

Handset G24

[1].

Table 1: G24 Java Compared to a Handset

Java is not the main feature. Java controls all activities.
Activation via Menu by the user. Activated automatically upon power-up.
MIDlet is for entertainment (Games, Calculators, …). MIDlet is a stand alone controller.

G24 KJAVA allows the customer MIDlet to control the following major features:

• Circuit Switched calls (data and voice)

• IP Network connections

• SMS/MMS

• GSM/GPRS Network status

• Serial connectivity

• SIM card

• NVM Data base (Phone book, File System, Record management)

• HW interfaces: A2D and GPIO

• Power (Low power mode, Airplane mode, Real Time Clock)

• MIDlet upgrade

6802981C50-C 5

CHAPTER 2 - PRODUCT OVERVIEW

Note

Figure 1 and Figure 2 present the differences between basic module architecture and the KJAVA one:.

Figure 1. G24 - Basic Module Architecture

Figure 2. G24 - KJAVA Architecture

Two G24 hardware configurations are available:

• OEM - display and keypad are disabled

• HMI - display and keypad are enabled

These two configurations look identical and can be identified by the model name printed on the units.

In order to facilitate G24’s integration with external systems, an evaluation board (EVB) should be u sed. The EVB consist of
the following features:

• 70 pin connector for G24 placement

• SIM card interface

• Antenna

• DC power supply

• USB and RS232 interfaces

• Digital and analog audio interfaces

• Switches, jumpers and LEDs for miscellaneous controls and indications
For a detailed description of the EVB, see “EVALUATION BOARD” and reference [2].

A handset, display and keypad can be attached to the EVB. Such an EVB configuration requires the use of an HMI G24 unit.

6 6802981C50-C

CHAPTER 2 - PRODUCT OVERVIEW

2.2 PRODUCT ADVANTAGES

1. Cheaper & Simpler - No External CPU (the traditional controller).

• Java MIDlet controls G24 functionality by running on its own CPU ("On target"), instead of using external control ler
CPU executing AT commands.

• Smaller PCB.

2. Friendly & Flexible - Java Language has rich verity of standard cellular APIs.

3. Easy maintenance - Over The Air (OTA) customer MIDlet application upgrade.

4. Provides full Java solution ­New Motorola proprietary API - dedicated for the M2M market segment.

5. Partial mode - AT command mode running si mu ltaneously with Java mode.
Example: Developers can use the G24 as a GPRS/EDGE module to connect to the internet via external TCP/IP stack (i.e.
connect it to a standard computer dialer), on the other hand, in parallel, a Java MIDlet can be run.

2.3 TYPICAL USE CASE

A typical M2M use case can be described as follows:
G24 integrated within a vending machine, when the machine is out of products it toggles a G24 I/O pin which notifies the MIDlet

(via G24 proprietary API). The MIDlet uses a standard SMS protocol (JSR 120) to notify a control center about this event.

Note

3.2.3 USB PC Driver

USB PC driver can be found in:

http://developer.motorola.com/docstools/USB_Drivers/Handset_USB_Driver/

3.2.4 Default RS232 Configuration

Baud rate 19200bps, 8 data bits, 1 stop bit, no parity bit, Flow Control = HW (Auto CTS/RTS)

3.2.5 Query System Information

There are two ways to query for system information. The first one is by using DM default outputs upon its startup. Some of its
outputs are:

• Software version

• Flex version

• DM version

The second way is by using OSC AP I via user own MIDlet. This can be done by using: OSC.getProperty method.

3.2.6 MIDlet Downloading

3.2.6.1 Serial (UART2)

Downloading a MIDlet via serial communications can be done using two different applications.
The first is a multipurpose tool developed alongside the G24, called "Jadpur".
The second is a Motorola Java loader application tool called "MIDway".
Both tools are available in MOTODEV website [4].
Jadpur Setup Stages:

Jadpur requires MS .NET framework installed on your PC.

1. Connect G24 UART2 to PC COM via RS232 cable.

2. Switch the KMgr pin to JTool mode.

3. Run Jadpur, use the Ports button to select the desired COM port, and from "File"->Settings -> Communication menu option
to configure the COM port baudrate to 19200 bps.In the Settings menu, check-mark the "One Click Download" option.

4. Use "File">"Open JAD" menu item to select the JAD file for download. JAD file properties will be displayed in the upper
right corner window frame.

5. Click the Download button, located in the bottom toolbar, to send the oemdownload command and send JAD file.

6. MIDlet download and installation process reports are sent to terminal window, ending with "MIDlet installation
completed".

MIDway Setup Stages:

1. Connect G24 UART2 to PC COM via RS232 cable.

2. Run MIDway and from "File"->Settings menu-> "Communication Settings" configure to 19200 bps. In the "AT command"
box enter "OEMdownload" and click OK.

12 6802981C50-C

CHAPTER 3 - GENERAL SETUP

Note

3. Switch the KMgr pin to JTool mode.

4. Select "File"->"Send AT command" menu item to send the download command to the device.

5. Select "File">"Open JAD" menu item to select JAD file.

6. Select "File">"Send JAD" menu item to send the JAD file (JAR file will be sent automatically).

Using "AT command" box and “Debug Log” Tab in MIDway imitates the traditional terminal use. It is possible to work
separately - sending JTool commands through external terminal and limiting the MIDway to handle the down load
process only.

3.2.6.2 Over the Air

Provides the ability to download and install content over a wireless network.
MIDlets stored on a web server can be downloaded to the unit in two ways:

1. Using the OT ADownload API from a UM.

2. Triggering an OTA download from the DM.

3.2.6.3 Common Errors

1. Attributes common to JAR manifest and JAD are not identical.

2. The MIDlet-JAR-Size attribute field does not contain the correct JAR size in bytes.

3. Wrong JAD attributes:
MIDlet-Name must be "UserMIDlet" (case sensitive).
MicroEdition-Configuration should be CLDC-1.1.
MicroEdition-Profile must be MIDP-2.0.

4. Untrusted MIDlet trying to replace trusted MIDlet (resolution: trusted MIDlet must be deleted first).

Refer to "Motorola MIDway User's Guide" in the SDK documentation for additional information.

3.2.7 Reflashing G24 Software

G24 enables its own software upgrade. Upgrades can be done via:

1. USB with RSD tool.

2. UART1 with PCLoader tool ("OEMreflash" command must be issued via UART2 before using PCLoader).

Note

ARCHITECTURE

4.1 GENERAL

The G24 KJAVA product runs one of the following two types of MIDlets:

User MIDlet (UM)

The UM is the customer's MIDlet which controls the G24 to its needs. The UM is the core concept within the G24 Java module.
It lets the customers to run their own code on the G24's CPU. UM is expected to run "forever".

MIDlet-Name attribute (in JAD file) must be "UserMIDlet" (case sensitive) and is verified during MIDlet installation
(Any other name will cause the MIDlet to be rejected).

Default MIDlet (DM)

The DM is a MIDlet provided by the manufacturer. It is a backup MIDlet which enables basic control in case UM has failed or
is absent (e.g. out of the factory). It also enables the customers to broadcast a command for a fresh UM download to all of their
newly scattered units

“APPENDIX B - DEFAULT MIDlet FEATURES” describes all the DM's supported features.

4.2 FUNCTIONAL DESCRIPTION

G24 KJAVA module has three entities:

• MIDlet Manager - Manages and executes the MIDlet.

• JTool Manager - Manages G24 maintenance

•JAL

• G24 SW reflash

• KDWP activation

• Module configuration

• OTA download Manager - Over The Air MIDlet download procedure

The handshake between these three entities, controlling the G24, is shown in Figure 4. These three entities are mutually exclu­sive, i.e. upon starting one of these entities the already running one will be stopped.

A GPIO pin ("KMgr pin") selects between MIDlet Manager and JTool Manager entities.
Pin status and selection is defined as follows:

• OFF (low HW signal) - JTool Manager.

• ON (high HW signal) - MIDlet Manager.
