Hello Alessandro,
Unfortunately the soda.dk.comm libraries are not very dynamic. We have to enumerate which ports will be available in the source code, then compile the libraries. If your port name is not in the enumeration, you can get this error. You can view the port
names here [1]. In your case, the port name /dev/tty.usbserial-NXGVOOYF is not enumerated. So, you can add your device name to the list and recompile, or a simpler solution is to create a soft link to one of the existing names:
ln -s /dev/tty.usbserial-NXGVOOYF /dev/tty.usbserial
Thanks,
--Dave
Hi all,
I just compiled Kura release 1.1.0 and imported the user workspace to Eclipse.
I would like to use the Serial Publisher example included, but I get
this error after configuring the serial port for the component. The
port actually exists, it is free and works using other applications.
This is the error stacktrace:

ExampleSerialPublisher:158 - Updated ExampleSerialPublisher... Done.
Do I need to configure the port somewhere to make it available from
soda.dk library?
My configuration is
Eclipse Version: Kepler Service Release 2 - Build id: 20140224-0627
$> java -version
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)
OSX Yosemite 10.10.1
Thank you
