Processing & Arduino communication

Projects Interfacing w/ Software on the Computer

I am running a Processing Sketch with a mysterious error which says in effect "Error opening serial port COM4: Port busy". The Arduino is connected to COM5 and running the StandardFirmata sketch.

Windows 10 does not show any COM4 connection.

Also, want to add that the COM4 does show in Arduino IDE . . . Tools>Port>Serial ports.

Any help would be appreciated . . .

If you want to talk to an Arduino with Processing then it must be connected to the same port as the Arduino.

I get that Grumpy Mike. . . The problem is that the Arduino shows up on COM5 when plugged into the USB port but Processing only sees COM4 (which is busy) and there is nothing on COM4????

Problem solved . . . Turned off Bluetooth which was using COM4
