Dear IOIO Users,
I'm having a problem to implement GPS Bee Kit that I have purchased from
Seeedstudio:
http://www.seeedstudio.com/depot/GPS-Bee-kit-with-Mini-Embedded-Antenna-p-560.html
I dont see any problems in Java Code, but nothing seams to be happening,
heres my code below:
package android.ioio.robot;
import java.io.ByteArrayOutputStream;

}

}
});

}
});
}
