could not open port 'COM3': PermissionError(13, 'Zugriff verweigert', None, 5)
could not open port 'COM3': PermissionError(13, 'Zugriff verweigert', None, 5)

have a great day. 

greetings 

btw. where to download the newest v ersion of uPCraft - i have running version 1.0 
and besides that: i have mused and thougtht that it wold be  a good idea to get other IDEs working with the ESP such as 

vscode 
thonny 
ATOM 
PyCharm 

but do i need to install the ArduinoIDE too !? 
love to hear from you
