Hello everybody,
since I use the rev. 1.03 I have a lot of trouble with my serial port #6.
It works a long time with upload and serial monitor without problems, but from one time to the other I get the error
" arduino serial port 6 is already in use "
I tried everything without success, even reboot doesn't work.
sorry for that, I pressed the button accidentally.
I believe I have an idea for the problem:
if I kill the program MMscan.exe from the MobileMaster the port is free, although this prog. doesn't use the comPort !!!???
