greetings from Bremen, Germany, with the following issue: I cannot upload sketches to Arduinos or other connected boards with Arduino-IDE because of busy serial port, even the easiest blink-program.
The problem seems to be an open serial port that is connected to an EV3-program. Although I no EV3 connected there is the 'EV3-SerialPort' listed in my port list. I connected the Arduino device to a make which was not connected to an EV3 yet, and everything worked perfectly.
The mentioned serial port is also listed as '/dev/cu.EV3-SerialPort' or 'dev/tty.EV3-SerialPort' without anything connected.
Does anybody know how I can get rid of this open serial port?
I already read the following posts and topics:
- Serial Port Busy on Mac: Arduino Forum
- OSX Upload-Issue: Error opening serial port: port busy

Thanks in advance,
