I’m trying to upload my sketch to the Arduino UNO using Visual Micro inside MS Visual Editor. It compiles fine but can’t upload saying that the port is closed.
In the port selector box two ports show COM3 and 4, although 4 indicates that it is connected to a Bluetooth speaker.
Do I need to give special permission, inside or outside of the app, for the port (COM3) to be used or is there some tick box that I haven’t checked in connection with the upload process?
Thanks
Jules
