I am going through Tiny OS tutorial lesson number 4 "Mote-PC serial communication and SerialForwarder" and I am stuck on the line where it says "Once you have installed TestSerial, you need to run the corresponding Java application that communicates with it over the serial port. This is built when you build the TinyOS application. From in the application directory, type
$ java TestSerial
However when I type this, I face the following error
Error: Could not find or load main class TestSerial
I tried several things to fix this issue, but none helped.
Solutions that I tried:
export CLASSPATH=.:/home/wsn/tinyos-main/apps/tests/TestSerial
2)set CLASSPATH to the directory where tinyos.jar is located
export CLASSPATH=.:/home/wsn/tinyos-main/support/sdk/java/tinyos.jar
3)run command using java -cp . TestSerial
however I keep having the same error
Is there any other better way to fix it?
I am using Virtual Machine with Fedora OS
I am trying to run the program on mib520 platform and I use iris motes
my java version
openjdk version "1.8.0_31"
OpenJDK Runtime Environment (build 1.8.0_31-b13)
OpenJDK Server VM (build 25.31-b07, mixed mode)
You must have skipped the step when you had to run the make command.
Navigate to the apps/tests/TestSerial folder and type make [platform]
(such as make telosb, make iris e.t.c), the makefile that will be run will be the makefile in the TestSerial folder which is defined as follows:
COMPONENT=TestSerialAppC
TOSMAKE_PRE_EXE_DEPS += TestSerial.class
TOSMAKE_CLEAN_EXTRA = *.class TestSerialMsg.java
TestSerial.class: $(wildcard *.java) TestSerialMsg.java
javac -target 1.4 -source 1.4 *.java
TestSerialMsg.java:
nescc-mig java $(CFLAGS) -java-classname=TestSerialMsg TestSerial.h test_serial_msg -o $@
TINYOS_ROOT_DIR?=../../..
include $(TINYOS_ROOT_DIR)/Makefile.include
So the makefile compiles TestSerial.java. After this you can proceed to installing the application and then running the TestSerial application.
So step by step on a iris mote for example you would
Navigate to the apps/tests/TestSerial
Folder
Make the application by typing make iris
Connect your mote and then type motelist
. This command will list all connected motes. The name of your mote should be listed under the "Device" section. Note this for use in the next two steps.
Install your application by typing the command make iris install.1 bsl, [DEVICE NAME]
. This will make and upload your program to your device.
Run the TestSerial application by running java TestSerial -comm serial@[DEVICE NAME]:iris
If you use another platform such as telosb then just replace all occurances of iris in the commands above with telosb.
