Release 8 EA 2
Beta Draft: 2014-03-25
This chapter demonstrates how to install the Oracle Java ME Embedded software on the Qualcomm Internet-of-Everything (IoE) board. The following items are required for installing and developing on the Qualcomm IoE board:
The Qualcomm IoE embedded board running the Brew MP operating system
A desktop PC running Microsoft Windows 7
A USB cable with a micro-B connector that can link the Qualcomm IoE board to your desktop PC
The Qualcomm IoE USB Drivers
The Qualcomm Netsetup Brew Application
The Qualcomm Brew MP SDK tools
A terminal emulation program, such as PuTTY.

Oracle Java ME SDK 8 EA 2
The NetBeans IDE 8.0 Beta
This document contains important information about the Qualcomm IoE board and its hardware.
Assemble and connect the board's components as listed in Chapter 3, "Hardware", and Chapter 5, "Hardware Configuration", of the Qualcomm IoE Development Platform User's Guide.
Connect the power supply as shown in the Qualcomm IoE Development Platform User's Guide and power on the board.
To use an AC-power source, see Section 188.8.131.52, "AC-powered operation."
To use a battery source, see Section 184.108.40.206, "Battery-powered operation."
The version used in this documentation is 7.12.5. Double-click on the installer executable, and install the application on your Windows platform desktop as per the instructions shown. You will need the Loader and Logger applications that are installed with the Brew MP SDK Tools in later sections.
To develop on the Qualcomm IoE board, you must first install the Windows USB drivers for the board. If you have not already done this, use the following steps:
Ensure that the Qualcomm IoE board is powered up by pressing the "PWR KEY" button on the board. Then, follow the instructions in Chapter 2, "Software Setup," of the Qualcomm IoE Development Platform User's Guide to properly install the USB drivers in Windows.
Ensure that the drivers are successfully installed by verifying the following hardware ports, as shown in Figure 1-1.
HS-USB Modem (AT command port)
HS-USB Serial Port (Java tooling port)
HS-USB Diagnostics Port
HS-USB NMEA Port (GPS)

Download and uncompress the Oracle Java ME Embedded Software 8 for the Qualcomm IoE board.
Obtain the latest
netsetup.sig signature files from the Qualcomm IoE website:
When the Loader application starts, connect to the board using the Connection type: Brew Devices (COM/DIAG), and whichever port matches the Qualcomm HS-USB Diagnostics Port, as shown in Figure 1-2.

If you are upgrading from the Oracle Java ME Embedded 3.4 release, you will need to delete all the files in the
/sys/mod/netsetup directories, including the
.sig files. After deleting the files, reboot the board.

Reset the board by pressing the "RESET KEY" on the board, then wait approximately 40 seconds for the Java VM to startup.
Start the Logger application in the same way you started the Loader application. Connect to the board using the Connection type: Brew Devices (COM/DIAG), and whichever port matches the Qualcomm HS-USB Diagnostics Port. Connect to the board, press the Start Logging button, and verify that the Java VM is sending logging information to the Logger application by checking for messages that come from the
[JVMStdout] file name. See Figure 1-3.
