ah yes I forgot about those additions. Try sending a firmware request.
ard.sendFirmwareVersionRequest()When the port opens a connection it is supposed to reset the arduino, like what happens when you use the serial monitor on the IDE but that doesn't actually always happen so you might be connected to the device but the event is never triggered. The arduino will only send the firmware when it first boots unless requested so just try this after the connect phase or hitting the reset button on the arduino.
