"Error, disabling serialEvent() for COM6 null"

edited November 2017 in Arduino


I have a program that was working fine in processing 2.x.x but wont work with 3.x.x. None of the text or tracings show up. While initializing, it looks like it hits a roadblock and throws the error "Error, disabling serialEvent() for COM6 null" in the console. Any ideas on how to troubleshoot?




  • Without seeing the code, there i nothing much to be done. You can start by running any sample code either from the example section or from the forum to verify your device is working. Then you will need to compare the differences between version 2 and version 3. You should consider posting the code if it is not too long. Anyways, that is what I would do...
