so, i got several machines that i need to keep connecting a laptop to debug and program, and i saw the option to use some hc05 i have here (the laptop has built in bluetooth), but i found some things that i might need help,
To access the RX - TX pins in my machines i would need to disassemble it entirely which would be hard, is there any way to use the usb (from the usb serial ch340) instead? if so, how can i do it? i have easy access to the arduino usb port (there is a "programming usb female" in the back of the machine, directly connected to an arduino mega).
I never worked directly with "reading and connecting to usb" in arduinos, but i have some experience with bluetooth
