Error ProcessingAPP

Dear all,
Once I try Pick Serial and click Connect, I got the error message below :

19:24:16 Serial connection start: detecte serial…
19:24:16 Serial detected: COM3
19:24:16 Serial connection attempt: COM3…
java.lang.ArrayIndexOutOfBoundsException: 16
at ProcessingApp$Communication.SerialRead(
19:24:18 Serial connection failed: detected serial, no serial responded

Your help is highly appreciated


it looks like a code looping to search a serial
but it s very difficult from the error message alone,
if you can share your code here, i will have a look

If you open Arduino ide and it was connected to Arduino processing won’t find com

Try to include your scketch manual selection of com port and post your code here
