as normal user it is still not working correctly [..] but as sudo it works fine. (normal user can’t save data to a file)
that’s odd, maybe you don’t have the permissions for the folder you want to save the file to.
Is there a possibility to use tabs or semicolon as field seperator?
Yes, it’s defined in WiimoteDataHandler.java in line 66: private static final String SEP = “, “;
So you could just download the source code, change SEP to whatever you like and compile & start the app with the included Ant build script. I don’t really want to make a new release just because of that.
An easier solution would be to just change the locale to English to get a point instead of a comma as decimal separator:
java -Duser.language=en -cp bluecove-gpl-2.1.0.jar:WiimoteLogger.jar org.uweschmidt.wiimote.logger.WiimoteLogger
