CC2540 Java Application

Other Parts Discussed in Thread: CC2540

Hi, I have the development kit for CC2540, and I was trying to use the JavaSimplePeripheral application to test my device. I followed the steps given on http://processors.wiki.ti.com/index.php/Category:JavaSimplePeripheral website, however eclipse keeps giving the following two errors, so I cannot change and build the code:

Description	Resource	Path	Location	Type

Archive for required library: 'lib/rxtxParallel.dll' in project 'CC2540' cannot be read

or is not a valid ZIP file	CC2540		Build path	Build Path Problem

Archive for required library: 'lib/rxtxSerial.dll' in project 'CC2540' cannot be read

or is not a valid ZIP file	CC2540		Build path	Build Path Problem

If you could help me with this, I'd appreciate.

I think this is not related to CC2540 but Java. In other projects using serial perhaps you are gonna have the same problem. I've found this:

 Install RXTX Java Serial library
1) Go to JRE directory, which by default is C:\Program Files\Java\jre1.6.***. Let's say JRE. 
2) Copy sis\lib\RXTXcomm.jar to JRE\lib\ext
3) Copy sis\lib\rxtxParallel.dll and sis\lib\rxtxSerial.dll to JRE\bin

And this:

Please see if it helps you and if you post again, try to include your operative system details ;)

Thanks for the response.

Already installed those libraries. As I said, I followed those steps given on the wiki page. But I still get those 2 errors. I'm on XP, as CC2540 works only on 32-Bit.

Just guessing, since I'm in the bus to home but... what is the answer if you make:

echo %JAVA_HOME%

in cmd.exe?

Hello,

The RXTX is part of java and not a TI supplied item. There can be a path issue with 32bit dll in 64bit java, I would try googleing RXTX for similar issues. That's pretty much what i had to do about a year ago when I muddled through the JAVA setup. I'm not a JAVA expert, but there are plenty of resources out there.

BR,

Thank you everyone who tried to help me. I managed to get through this problem by running the project in netbeans. Therefore, I presume the issue was peculiar to eclipse. Note that eclipse was not my preference, the only reason I tried to use eclipse was because on the wiki site where the JavaSimplePeripheral project is, it said so. Thus, I suggest whoever will use this project, work on it in netbeans instead of eclipse.

Thanks again,

Oguz

Also I would like to note that, in ConnectionManager.java there has to be a change in the outputBuffer array under the following two methods (see below), so as to get the two keys on the key fob working. Please update the given java code on http://processors.wiki.ti.com/index.php/Category:JavaSimplePeripheral so that people who will be using it wouldn't struggle and waste time finding the bug and fixing it.

public void simpleKeysEnabler()

int[] outputBuffer ={ 0x01, 0x12, 0xfd, 0x08, 0x00, 0x00, 0x00, 0x00, 0x34, 0x00, 0x01, 0x00 };

public void simpleKeysDisabler()

int[] outputBuffer ={ 0x01, 0x12, 0xfd, 0x08, 0x00, 0x00, 0x00, 0x00, 0x34, 0x00, 0x00, 0x00 };

Thanks,

Oguzhan

Hello Oguzhan,

could you please explain to me the meaning of the different bytes? I have some problems with the Java program.

Thanks

Peter
