Accessing serial devices from emulator (OSX 64bit/Eclipse Kepler 64bit) #10

darugnaa · 2014-06-16T14:49:30Z

I have some troubles instantiating a serial connection to a modbus device using the emulator. The hardware is a Serial-to-USB FTDI cable with a modbus device attached.
This works on the raspberry (I see the FTDI cable as /dev/ttyUSB0) and the modbus data connection is fine.

However if I try to use the same FTDI cable on my development machine things don't work.
In my "Run configuration" I specified the VM argument: -Dkura.ext.dir=/Users/ale/dev/tmp/ to a directory containing javax.comm.rxtx.properties file declaring the serial port (/dev/tty.usbserial-FTWDSO8Z).
When I try to access the port Kura says it doesn't exist:

Hello Alessandro,

The serial library has been updated to support the OSX emulator. A
couple of notes:

The javax.comm implementation in Kura does not support dynamic port
names. We hope to have this in the future, but are waiting on IP
approval from Eclipse. So, this means the port names are hard coded in
the JNI. Port names likes "/dev/ttyUSB0, /dev/ttyS0, /dev/tty.usbserial"
should work without issue. However, if you have a name such as
"/dev/tty.usbserial-FTWDSO8Z" you will need to link to a known port:

ln /dev/tty.usbserial-FTWDSO8Z /dev/ttyS0

Then use port name "/dev/ttyS0".

There is an outstanding issue in Eclipse regarding the red
"Terminate" button (read here:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=38016). In the OSX
emulator, if you are using a serial port and use the red "Terminate"
button, this may cause the port to remain locked and can cause system
crashes. To avoid this, I would first stop the OSGI container in the
console with 'stop 0', then terminate the JVM.

Let me know if you have problems or have questions.

Thanks,
--Dave
