i tried to Connect an physically connected NodeMCU1.0 Board via VirtualHere Server V4.3.3 with Client V5.2.4 over Network.
The Driver "CP2102 USB to UART Bridge Controller" could be installed perfectly. After that Arduino V1.8.16 was started and a "blink-Program" has been set up. After Compile The Upload Button was pressed (with COM3 = CP21.....) and following error happens:
"serialutil.SerialException: could not open port 'COM3': PermissionError(13, 'Device not ready', None,21)
Trying this on real machine everything works fine (...) .
Thank you very much for any help,
