  • Here are the problems & solutions I had.
    Problem: TouchOSC on the iphone Times out and is unable to download layout.
    Solution: Open up the firewall and add an exception,
    select TCP add the port number 9658. This stops the firewall from blocking transmission.
    Problem: Procession GUI responds to the iphone layout being touched (red dot lights up) But the LED will not illuminate.
    Solution: Find the code in the processing that looks like this "this, Serial.list()[0]" Change the 0 to be what your COM port your Arduino is attached to.
    NOTE: my COM port was COM3 but actually the number required was 1. "Serial.list()[1]"
    I dont get this Why 1 and not 3 ?
    So don't be deterred if COM 7 isn't 7 maybe try 5.

  • Thank you for posting this.
    I had some problems along the way but all were answered for me by reading everyones comments.
    This tutorial has given me just enough information to see the potential this kind of connectivity has.

No public wish lists :(
