Question on access to AppDesigner

I've written an app to control the Trossen Robotics Arm Pincher. It is initialized by this command: arb = Arbotix('port','/dev/tty.usbserial-AI05UU3S','nservos',5) This creates a variable in the workspace arb that has specific properties methods etc. Doesn't work in App Designer. Whole program hangs.

Are you setting it to be a property (that you've added) of the app?

properties
  arb
end

Whatever call back creates it:

app.arb = Arbotix(...)

Thank you I will try this

I tried it and nowit does not lock up, but when I have another action like app.arb.setpos(1,pi/2,10) it does nothing. When I run the same commands in the command window they work!

I'd have to recommend following standard debugging procedures. Put a breakpoint on that line and step into it.
