Installing java toolchain to connect Intel Mote 2 to a PC:

It should be possible to interact with deployed sensor networks from any PC. In TinyOS, this is accomplished by connecting a dedicated mote (a base station) to a PC. Base station provides a NIC interface to the sensor network through a virtual serial port. SerialForwarder java application further lets you map the virtual com port to a TCP port on your PC, where any number of applications (both local and remote) can connect.

iMote2 can be connected to a PC through the interface board (IIB2400) by connecting the mini USB port on the interface board to a USB port on your PC. FTDI USB drivers for Windows XP are required. After connecting iMote2 to a PC and pressing the reset button (iMote2 is powered off by default), two new virtual COM ports will be detected in Device Manager. The mote can send data to a UART which maps to the COM port with lower number. However, TinyOS java toolchain has not yet been configured for the iMote2 platform. We provide detailed instructions how to configure these tools in this document. It is assumed that you have finished installation of tinyos toolchain.

Step 1 Installing Java

• Download and install the java sdk from sun http://download.java.net/jdk6/
• Add the following line to your .bash_profile file

	export PATH=/cygdrive/c/Program\ Files/Java/jdk1.6.0_02/bin:$PATH

• Download commapi
• Copy the comm.jar and javax.comm.properties files to

	c:\Program Files\Java\jdk1.6.0_02\jre\lib\ext\
	c:\Program Files\Java\jdk1.6.0_02\jre\lib
	c:\Program Files\Java\jdk1.6.0_02\lib\

• Copy win32com.dll to

	c:\Program Files\Java\jdk1.6.0_02\jre\bin\

• Add the following to your CLASSPATH

	export CLASSPATH=".;c:/Program Files/Java/jdk1.6.0_02/lib/comm.jar"
	export CLASSPATH=$CLASSPATH:`$TOSDIR/../tools/java/javapath`

Step 2 Installing FTDI

• Download drivers from http://www.ftdichip.com/Drivers/VCP.htm
• Plugin the iMote with debug board and look for drivers in the CDM 2.02.04 WHQL Certified folder

Step 3 Configuring tinyos java toolchain for iMote2

• download java.zip
• copy imote2 directory to $TOSROOT/tools/java/net/tinyos/message directory
• copy .platform.properties file to your $HOME cygwin directory
• go to $TOSROOT/tools/java/jni and type "make install"
if you get an error message:

• find the location of java jre on your PC (it is /cygdrive/c/Program Files/Java/jdk1.6.0_02/jre/bin on my machine), for example by typing

$TOSROOT/tools/scripts/locate-jre --java

• copy "$TOSROOT/tools/java/jni/getenv.dll" file to this jre directory
• define environment variable TOS_PLATFORMS with the location of .platform.properties file
*important*: this should be a windows style path, not a cygwin style path, for example:


	export TOS_PLATFORMS=C:/cygwin/home/brano/.platform.properties

Step 4 Test the setup

• install imote2 mote with $TOSROOT/apps/TOSBase, attach IIB2400 board to the imote2, attach USB cable to the *interface* board (that is, not to the mote), push the mote's reset button
• install another imote2 with $TOSROOT/apps/CntToLedsAndRfm, as soon as the install finishes, TOSBase mote should start blinking green LED (this happens every time it receives a tinyos msg)
• start SerialForwarder java application (change COM3 to the actual virtual com port)

java net.tinyos.sf.SerialForwarder -comm serial@COM3:imote2 -port 9001

the "Pckts Read" field in SerialForwarder GUI should start increasing
(if you get "NoClassDefError" go to $TOSROOT/tools/java directory and type 'make' to compile java tools)
• connect to the serialforwarder with java net.tinyos.tools.Listen application
"Num Clients" field in SF GUI should increase; tinyos messages should be shown on your Listen screen
