This can be a silly question but I'm having a trouble with serial communication between arduino nano with other serial device. Please help me to handle it.
I'm currently doing a RF communication project using arduino nano and radio telemetry which is using serial communication. I tried to use SoftwareSerial but unfortunately, every pin is being used on arduino nano to control other extra devices. So I decided to have serial communication via usb port of arduino nano
Firstly, I directly connected rx and tx wire of RF device with D- and D+ of B type mini USB. but it did not work
Secondly, I tried to connect rx and tx wire with arduino nano via UART to USB bridge, cp2102 module. I soldered a female USB - male mini USB wire for this connection. but It did not work. the wiring that I build seems like the picture below.
Did I miss something? It doesn't work theoretically anyway?
Thank you in advance
