1. Introduction

1.1. General Information The MOBISA is a self-contained quad-band mobile phone module which offers most of the functions of general GSM/GPRS mobile phone plus Open MOBISA development environment for future external functions by customer. The Open MOBISA Software Suites allow you to develop, compile, test, debug, download and natively execute your applications written in standard ANSI C directly on your MOBISA Mobile Phone Module. It comprises Nucleus real-time operating system, ARM developer suite. With the open source development environment, the developers can complete access all the low-level hardware and software. The feature rich open platform afford you great flexibility, enabling you to respond to changing demands. One of the main features of the MOBISA Mobile Phone Module is to support Java, at the heart of the MOBISA is the Java virtual machine, making it a high performance, open-platform module. Being based on Java, the MOBISA provides developers to design Machine-to-Machine(M2M) applications with a sophisticated developer’s software platform. MOBISA was designed to satisfy the needs of different M2M applications such as:

• Metering • Security • Fleet management • Vending machine • Remote maintenance and control • The Internet of Things

The MOBISA with Java technology is the missing link between M2M applications and the world of IP-based services and trend of global Internet of Things. The new standard provides control of M2M applications and enables user-friendly over-the-air software updates(OTA) for reliable e-maintenance. The MOBISA is designed to popularize the development of mobile application , our goal was to “Make It Easy to Develop the Mobile Applications”.

Figure 15:Catcher Tool

9.6.2. Quick Start Guide The chapter is a starting guild for logging messages with Catcher Tool. A database file of the MOBISA and a workspace file for filter setting are required, the database file is usually named BPLGUInfoCustom_XXX and is located in mcu\tst\database_classb. The workspace is a file with extension name *.csw. To start logging, please follow the steps:

1) Open a workspace file. 2) In menu config, set the database file. 3) Click the logging mode button, and then configure the RS232 port. 4) Click the Connect Button. 5) Disable the sleep mode on MOBISA, and click the filer button on Catcher to set

filter. If all setups are correct, logged messages will be displayed on Primitive Log window.

11. Programming This section descriptions how to install software images onto the flash memory on the MOBISA. This procedure can be used to install a customized version built by the customer or to restore the flash image if it is destroyed or damaged. This procedure will work even if the flash is completely erashed.

11.1. Setting up the programming environment

11.1.1. Requirements • A Windows XP PC • The FlashTool software

FlashTool is an application that downloads build images and binary data to MOBISA module.

• The driver of PL-2303 USB-to-Serial Bridge Controller for Windows XP

11.1.2. Preparing to Install

11.1.2.1. Installation of High-Speed USB-to-Serial Bridge Cable

A USB-to-Serial bridge cable also enables high-speed download up to 921,600 bps. 1) Plug the USB-to-Serial cable into the computer USB port. 2) When the new COM ports device was discovered by MS Windows, install its

driver. 3) After driver has been installed successfully, a new COM port device can be seen

in the Device Manger. Below are the steps for entering the Device Manager: On the Desktop, right-click on My Computer -> Manager -> System Tool -> Device Manager -> Ports(COM & LPT).

The following figure illustrates the new device(COM3) in the Ports item.





- 34 -

Figure 17: Device Manger - COM Ports

11.2. FlashTool Installation Procedure This software no need to install, just copy the FlashTool folder to your computer. Double click “Flash_tool.exe” in the folder to run the program.

Figure 18: Flash Tool

11.3. Updating/Restoring the Flash Image Follow the steps below to download the firmware into MOBISA:

1) Power off the MOBISA module.





- 35 -

2) Click on “Options” and choose “Bandrate” from the menu, make sure baud rate was set to 926100.

3) You’ll need to figure out which serial PORT(COM) you are using, plug in the USB-to-Serial Cable, check the Device Manager, look for “Prolific USB-to-Serial Comm Port(COMx)”. Select the corresponding COM port.

4) Press the “Download Agent” button and select the “MTK_AllInOne_DA.bin” file from FlashTool folder.

5) Press the “Auth File” button and select the “TEST_AUTH_MTK_6225.auth” file from FlashTool folder.

6) Press the “Scatter-loading” button and select the “scatMT25.txt” from the release firmware folder or mcu\build\MT25 after you rebuild the code.

7) Assign the target image file Once the scatter file has been opened, the image names are listed in the viewing panel. To manually assign a resource file to an image, double-click on the image name: a file browser appears for file selection as following figure.

Figure 19: Flash Tool - Option

8) Click the DOWNLOAD button to start downloading the built image to MOBISA. 9) Power on the MOBISA to start the download process.

* Note that to interrupt the download process at any time, press the STOP button.
