So I have a robot with 2 wheels and it works fine with a USB cable to drive. But I want to upgrade it to bluetooth. I have a HC-06 module and I upload the code to the board with rx and tx disconnected and the USB connected. But when I open an app called 'Serial Debug Assistant' and try to open and connect to the hc-06 on COM 11 (which is the COM for incoming) and type and send a command the it displays a message 'this port is already in use'. So it is. I want to know how to change the COM port something (being the hc-06 module) is assigned to. Can anyone help?
