Hello @dfrey,
Thank you for your help. I have installed the jumper and the demo now works when run from the Terminal. If, however, I follow the instructions from a different topic or here and instead try run this perticuler project through DS the LED does not blink. It should be noted that I have not had the same issue with timerLed, that project works fine through DS.
I have checked that the app is installed on the board and that it is running, still no luck.
